Deutsche Fluglehrer bilden auf Blackhawk aus

 

09.07.2014 Bundeswehr

 

Im „Army Aviation Center" in Fort Rucker im US-Bundesstaat Alabama bilden die US Streitkräfte eigene und ausländische Hubschrauber Besatzungen aus. Zurzeit unterrichten dort auch sieben Fluglehrer der Bundeswehr auf der Bell UH-60 -- Blackhawk. Für die deutschen Ausbilder bedeutet dies ein enormer Erfahrungsgewinn. Gleichzeitig werden durch ihren Einsatz sog. Credits erwirtschaftet, die wiederum für deutsche Flugschüler eingesetzt werden können. Pro Jahr nehmen rund 60 Bundeswehrsoldaten an Ausbildungen und Lehrgängen in Fort Rucker teil.

Mobile Gun System in Afghanistan

Mobile Gun System in Afghanistan

 

Jun 28 by DAVID AXE

 

A taxonomy of armored vehicles, volume two—the Mobile Gun System

 

The U.S. occupation of Iraq is over. The Afghanistan war is winding down. Today America faces “emerging threats in an increasingly sophisticated technological environment,” according to Gen. John Campbell, the Army vice chief of staff.

 

For the U.S. ground combat branches that means a renewed emphasis on fast-moving armored warfare. The Army and Marines are dusting off heavy vehicles that played a minor role in Iraq and Afghanistan.

 

In this series, we spotlight some of the more obscure, and fearsome, armored behemoths. The battle wagons of a new era of warfare. The focus of this volume—the Army’s very troubled Mobile Gun System.

Kopin® Corporation (NASDAQ:KOPN), the largest U.S. developer of display systems for wearable technologies and military applications, today announced it has received a $9Million order for display modules in support of the U.S. Army’s Thermal Weapon Sight (TWS) program. This urgent order was placed by a major customer to replace a competing display technology which was not able to meet the stringent military specifications. As a result of this new order, we expect our revenue for 2014 will be in the range of $24Million to $28Million, an increase of $6Million from the earlier projection.

 

“Dismounted soldier environments such as TWS are the harshest environments for any product to endure,” stated Michael Presz, the Company’s Vice President of Government Programs. “We were informed that reliability issues were discovered with the alternative display technology during extensive testing. Our unique AMLCD technology, however, has demonstrated proven performance and reliability for the TWS program in over 15 years of deployment. Kopin has delivered more than 200,000 display units to the TWS program, either in component form, in a display module or as a complete eyepiece assembly, with essentially zero product returns.”

Precision Air Drop Contract For Lockheed Martin

 

16/06/2014 by Paul Fiddian - Armed Forces International's Lead Reporter

 

United States defence officials have contracted US aerospace/defence firm Lockheed Martin to develop technology able to improve the accuracy of air drops.

 

With countless applications, air drops are a hugely important part of modern military operations. So often, the presence of transport aircraft such as USAF C-130 Hercules variants or C-17 Globemaster IIIs dropping supplies has been a godsend for victims of natural disasters or soldiers in distress.

 

However, wind drift and other factors can send the supplies off target: a scenario Lockheed Martin's modified WindTracer system aims to correct.

 

Precision Air Drops

 

The US AFRL (Air Force Research Laboratory) has ordered the firm to produce a PAD (Precision Air Drop) system that gets supplies to the ground more quickly and more accurately than can be achieved at present.

 

WindTracer has now been in operation for some ten years. It works by hitting atmospheric dust particles with infrared light beams - the returning beams indicating both wind speed and wind direction. Especially at airports, WindTracer thus acts as an early warning system, giving pilots crucial information on the potential for wind shears, gust fronts, microbursts and other weather phenomenon.

 

Air Drop Contract

 

The Lockheed Martin air drop contract should involve a version of WindTracer that's dropped from altitude, measuring wind speed and wind direction during its descent and transmitting real-time data back to those in the overhead.

 

"Currently air drop missions require several flyovers to accurately determine wind readings, but our WindTracer technology would eliminate the need for so many passes" explains Lockheed Martin division STAR Labs' vice president, Doctor Kenneth Washington. "WindTracer is an adaptable commercial system. By developing this prototype, we're putting this technology on a path for fielding."

 

"Applying proven technology to the air drop mission is the most effective way to deliver fast, affordable innovation", adds Lockheed Martin Commercial Ventures president Mike Hamel. "WindTracer has been helping commercial airliners take off and land safely for years, and it is an ideal technology to support military air drops."

Major General Patrick J Donahue II handed command of US Army Africa (USARAF) to Major General Darryl A Williams during a ceremony on Hoekstra Field at Vicenza in Italy.

 

General David M Rodriguez, Commanding General of US Africa Command (Africom) presided over the change of command ceremony.

 

“Under General Donahue’s leadership, Army Africa worked with the first Regionally Aligned Force and helped ensure its success,” Rodriguez said.

 

“When the regionally aligned force is training, exercising or enabling partners, US and African soldiers benefit from enhanced skills, inter-operability and readiness. The regionally aligned force also supports the protection of US personnel and facilities on the continent.”

 

Rodriguez praised Donahue’s leadership of USARAF.

 

“Another way the US Army is transforming to meet the challenges of the 21st century security environment is by developing leaders who can work effectively with a broad range of partners,” he said.

 

“This includes partners from other countries, government agencies and military services. Army Africa has deepened partnerships with African and European militaries, with civilian agencies and with other Service components,” Rodriguez said.

 

Rodriguez welcomed Williams as the incoming USARAF commander.

 

“As Pat and Maureen Donahue depart for Army Forces Command, they pass leadership of the Army Africa team to Darryl and his wife Erin. I know the Williams’ will continue to lead this team superbly. Thank you all for your continued contributions to advancing our nation’s interests in Africa. We will go forward, together," Rodriguez said.

 

Williams said he was thankful of the opportunity to serve as USARAF’s commander.

 

“Gen Rodriguez thank you for having confidence in me and giving me an opportunity to command this great organisation of soldiers and civilians.

 

"Pat (Donahue), the work you have done with the US Army Africa team has made great changes in Africa. I am honoured and humbled to follow in your footsteps and look forward to the challenge.” Williams said.

 

“USARAF’s mission on the continent of Africa could not be more relevant than it is today. The team of professionals you have assembled is proving each day how valuable they are to the mission. I look forward to working alongside these fine men and women,” the new force commander said.

L’US Army vend ses CH-47D Chinook

 

9 juin 2014 par Frédéric Lert – Aerobuzz.fr

 

Le dernier rapport du Sénat français sur les forces spéciales vient une fois plus de le rappeler : il manque aux militaires français des hélicoptères de transport lourd. La plupart de nos voisins européens en ont, mais pas nous. C’est d’autant plus regrettable que ceux qui font la guerre au Sahel par 40°C à l’ombre (ou plus), et qui auraient bien besoin de ces bêtes de somme, ce sont précisément les Français.

 

Le rapport du Sénat, qui cite le Chinook en exemple, donne les chiffres suivants (sans préciser toutefois les altitudes et les températures d’opérations) : la capacité d’emport du Caracal est de 900 kg à 300 km. L’hélicoptère américain emporte quant à lui 5500 kg, soit six fois plus, sur la même distance. Le rapport rappelle également que « l’hélicoptère de transport lourd (HTL) avait fait l’objet d’un « objectif d’état-major » au mois de juin 2006 et un rapport de l’Inspection Générale des Armées Air fin 2006 avait recommandé l’acquisition d’une telle capacité. Plusieurs hypothèses avaient alors été évoquées : échange de potentiel au niveau européen (…), achat sur étagères, lancement d’un programme industriel européen. Aucune de ces pistes n’a été poursuivie afin de ne pas remettre en question la commande des 68 NH-90 de l’armée de terre ». Ajoutons qu’à la fin de la décennie, l’armée de Terre avait envoyé des missions d’études à droite et à gauche pour étudier les différentes solutions possibles. Bref, l’armée de Terre aura ses NH90 Caïman, magnifique appareil aux commandes de vol électriques. Mais elle n’aura pas ses hélicoptères poids lourds qui sentent fort l’hydraulique.

 

Dans le même temps, on apprend que l’US Army vient de vendre un nouveau lot de dix CH-47D à des opérateurs privés. Le processus de vente avait été entamé en décembre dernier et s’est terminé en avril 2014. Les « D », âgés de vingt ans en moyenne, sont progressivement remplacés dans les régiments de l’US Army Aviation par des « F », plus récents et plus puissants. Le lot de Chinook a été vendu à trois opérateurs nord-américains spécialisés dans le travail aérien : Billings Flying Service, Columbia Helicopters et CHI aviation. Les prix s’étageaient de 2 à 3,5 millions de dollars suivant les potentiels des appareils. Au total, les dix CH-47D sont partis pour 28 millions de dollars, soit une vingtaine de millions d’euros. Bien moins cher qu’un seul NH90.

 

N’allez pas croire que cet article suggère que les armées françaises auraient pu acheter des hélicoptères d’occasion auprès de l’US Army. On sait bien qu’acheter du matériel militaire auprès de l’Empire, c’est se lier les mains sur le terrain diplomatique tout en sabotant la fameuse BITD française (Base Industrielle et Technologique de Défense). On sait aussi que ces affaires là sont bien plus compliquées qu’elles ne le paraissent et que des appareils d’occasion ne sont pas forcément de bonnes affaires techniques et financières. Il faut former les équipages et les mécaniciens, acheter des pièces…

 

Si de simples opérateurs privés franchissent le pas, c’est sans doute par pure inconscience ou sur le conseil de leurs actionnaires qui souhaitent plomber les bilans… On sait enfin que pour défiler le 14 juillet, le CH-47D d’occasion n’est ni très glamour ni suffisamment français. Mais pour servir de bétaillère et de camion de déménagement dans le sable du Sahel ?

 

L’US Army prévoit de vendre dix autres Chinook cette année. Si les armées sont intéressées, elles peuvent toujours aller jeter un œil sur le site gsaauctions.gov, tout y est ! En attendant, pour transporter un groupement tactique parachutiste vers ses bases d’assaut dans le massif des Ifoghas, il nous reste le système D et les TRM 10000 que le monde entier nous envie…

Du lundi 12 au jeudi 15 mai 2014, le 1er  régiment d’artillerie (1er RA) a organisé ROYAL BLACKHAWK, un exercice de coopération franco-américaine, dans la région de Belfort.

 

Durant trois jours, près d’une centaine de soldats regroupant les équipes de détachements de liaison d’observation et de coordination (DLOC) du 1e RA, la 7e brigade blindée mais aussi des hélicoptères d’attaque du 1er RHC, des avions de la BA 102 et deux Blackhawk américains du 214th Aviation Régiment -basé en Allemagne-, ont participé à l’exercice. L’occasion de les entraîner aux missions d’appuis feu-artillerie et aux procédures de combat interarmes et interarmées.

 

Le LCL Alexandre Lesueur, chef opération du 1er RA, a fait le bilan de cet exercice :  « Nous sommes dans la phase d’entraînement collectif de notre cycle de préparation, les équipes, déjà aguerries, progressent encore. Chacun a travaillé dans sa spécificité, mais toujours au profit de l’autre. C’est bien là l’essentiel de notre mission. »

La mission ISR de Dynamic Aviation prolongée d'un an en Afghanistan

 

01.05.2014 par Philippe Chapleau  - Lignes de Défense

 

Dynamic Aviation, l'un des spécialistes US de l'ISR, va poursuivre ses opérations aéroportées, pendant une autre année en Afghanistan. La firme US, qui est présente depuis 2006, y maintient trois appareils (pour ce type de prestations, elle dispose de Dash 8 et de King Air). L'avis du Pentagone (daté du 29 avril) est intéressant (lire ci-dessous) parce qu'il prolonge le contrat jusqu'au 30 mars 2015, donc au-delà la date fatidique du 31 décembre 2014 qui est supposée marquer le retrait des forces étrangères.

 

Dynamic Aviation Group Inc., Bridgewater, Va., was awarded a $22,359,136 firm-fixed-price contract for continued operations, sustainment, and integration of three communications electronic attack with surveillance and reconnaissance aircraft, currently deployed in support of Operation Enduring Freedom. Fiscal 2014 operations and maintenance, Army funds in the amount of $5,919,114 are being obligated at award. Work will be performed in Bridgewater, Va. (20 percent) and Afghanistan (80 percent), with an estimated completion date of April 30, 2015. One bid was solicited and one received. The U.S. Army Contracting Command, Redstone Arsenal (Aviation), Redstone, Ala., is the contracting agency (W58RGZ-14-C-0037).

 

Le Pentagone a diffusé le même jour un autre avis, concernant la prolongation d'autres prestations en Afghanistan; il s'agit d'une extension au profit de DynCorp qui entraine depuis des années la police afghane. Or l'extension (lire ci-dessous) ne court que jusqu'au 31 décembre prochain.

 

DynCorp International LLC, McLean, Va., was awarded a $49,898,634 modification (P00034) to cost-plus-fixed-fee contract W91CRB-11-C-0053 for mentoring and training in support of the Afghanistan Ministry of Interior and Afghanistan National Police. Work will be performed in Afghanistan with an expected completion date of Dec. 31, 2014. Fiscal 2013 other funds in the amount of $24,949,317 are being oblicated at award. The U.S. Army Contracting Command, Rock Island, Ill., is the contracting agency.

 

Hésitation, hésitation... Que restera-t-il de la présence US en Afghanistan au 1er janvier: 0 personnel, 5000, 10000? Les négociations, au point mort avec Karzaï, vont reprendre avec le nouveau président. L’ex-ministre des Affaires étrangères Abdullah Abdullah a obtenu 44,9% des voix au premier tour du scrutin présidentiel , selon la Commission électorale indépendante (IEC), devançant l’économiste Ashraf Ghani (31,5%). Suite après le second tour.

The active US Army will receive National Guard Apache attack helicopters under a new plan. (US Army)

Apr. 8, 2014 - By PAUL McLEARY – Defense News

 

WASHINGTON — In a surprising move, the head of the US National Guard Bureau has given his blessing to the US Army’s plan to move all of the Guard’s Apache attack helicopters into the active force while receiving several hundred Black Hawk and Lakota multi-use helicopters in return.

 

“As a member of the Joint Chiefs of Staff, we have fought, and we have discussed many, many times, these topics,” the National Guard Bureau chief, Army Gen. Frank Grass, told the Senate Armed Services Committee on Tuesday “And I provided my best military advice. I’ve assessed the risk. I’ve given the cost.

 

“But the decision’s been made, Mr. Chairman,” he said. “And my job now is to begin to look at the effects across the states, and figure out how we’re going to execute this plan.”

 

The general’s acquiescence came as a surprise in what many anticipated to be a contentious hearing, especially after Grass told the House Defense Appropriations subcommittee on April 3, “I do not agree with the proposal to take all Apaches out of the guard.”

 

Grass testified before the committee with Army Chief of Staff Gen. Ray Odierno, who has been campaigning for the aviation restructuring for months, but has encountered stiff resistance from the Guard leadership and sharp questions from Congress.

 

The chief emphasized that the aviation plan is a necessity given the tightening fiscal picture for the Army, and the expense of upgrading its helicopter fleets.

 

“No one is fully satisfied with the final outcome, including myself,” he offered. “However, the reality is the funding in the future will not allow us to have everything we may want. These cuts will still occur, even if we delay our decisions or fail to address the issue as the total Army. The results will be hollowing out of our Army.”

 

The plan calls for the Army to retire its fleet of Kiowa Warrior scout helicopters and replace them with the Guard’s Apaches, which will team with Army drones to perform the scout mission. Overall, the Army will lose 687 aircraft, including 600 Kiowas.

 

The active component will also eliminate three of its 13 Combat Aviation Brigades while the Guard will retain all of its 10 aviation brigades.

 

The Army expects to save about $12 billion over the next several years by taking this approach, beginning with $2 billion in fiscal 2015 alone.

 

The strategy “salvages our plans to modernize our aviation fleet,” said Col. Frank Tate, the Army’s chief of aviation force development, at an event across town at the same time the chiefs were testifying on Capitol Hill.

 

“We were lowering our rates of procurement on our biggest systems” due to the cost of maintaining seven different helicopter platforms, Tate told an audience at the Center for Strategic and International Studies.

 

The Army’s proposal to get rid of two models of the Kiowa and the TH-67 trainer helicopter would eliminate three aircraft models of the Army’s seven, as it continues to modernize the Chinook, Apache and Black Hawk until replacement helicopters begin to enter the fleet some time in the 2030s.

 

While the Army might be losing helicopters, it is increasingly eyeing shipboard operations for the 690 Apaches that it is keeping.

 

Operating from ships at sea “seems to be a growth capability, and we do sense that there is increasing demand out there” in South Korea and the Central Command area of operations, said the Army’s director of aviation, Col. John Lindsay.

 

“We’ve gotta make sure that we have the appropriate demand signal coming in from the combatant commanders,” however, in order to determine “how much maritime capability does the Army need to invest in,” he added.

 

Lindsay acknowledged that over the long term, “we still have some work to do” to determine how much the Army wants — or needs — to invest in operating Apache helicopters from naval vessels.

 

In a nod to Marine Corps sensitivities over the issue, Tate was quick to point out that flying Army helicopters from the decks of ships isn’t necessarily anything new. He was involved in operations in Haiti in the early 1990s where the Army flew Apaches off the back of short-deck Navy frigates.

 

“The Army is not new to this idea of maritime operations and ship operations,” he insisted

US Army leads development of improved coating for howitzer breech spindles

8 April 2014 army-technology.com

 

The US Army Research, Development and Engineering Command's (RDECOM) Armament Research, Development and Engineering Center (ARDEC) is working on a project to identify, evaluate and implement an improved coating process for howitzer breech spindles.

 

Working in collaboration with the Product Manager Towed Artillery Systems (PM TAS), the ARDEC has shortlisted three new coating and application processes for further testing based on performance and cost. It had been evaluating 12 material formulations in small samples.

 

The selected processes include high power impulse magnetron sputtering from Sheffield Hallam University, accelerated plasma arc from Phygen Coatings, and electroless nickel plating.

 

The team had developed a list of ten primary metrics necessary for a new coating and application process, which included resistance to corrosion, mechanical wear and high temperatures.

 

In an effort to ensure that the coatings withstand the rigours of soldier use, the team has joined forces with the Aberdeen test center for live-fire testing on a howitzer range.

 

After the first round of firing, the spindle undergoes 30 days of weathering in a caustic and acidic propellant byproduct, called a swab water. This is to replicate potential combat conditions, and is followed by another round of firing and then a final weathering cycle.

 

ARDEC project technical lead and materials engineer Dr Christopher Mulligan said the new processes are vastly outperforming the legacy chrome electroplating in terms of corrosion and wear.

"The new technique will boost the howitzer performance, reduce the logistical burden on the soldier, and reduce environmental hazards."

 

The team has also identified and funded a newly developed chemical vapour deposition type coating known as Carbonyl from Canada, and is planning to start testing over the next few months.

 

A final decision is expected to be made within 90 days of the completion of testing of all processes, with an aim for a production-ready coating within six months to a year.

 

The new technique will boost the howitzer performance, reduce the logistical burden on the soldier, and reduce environmental hazards. According to Mulligan, it will save the government more than $2m each year.

 

The evaluation of foreign processes and materials is being funded through the foreign comparative testing (FCT) programme.

US Army Rejects GD's Vehicle Protest; Company Mulls Further Action

General Dynamics will have to decide whether to pursue a more formal protest regarding the fairness of the Armored Multi-Purpose Vehicle program. (US Army)

 

Apr. 7, 2014 - By PAUL MCLEARY – Defense News

 

WASHINGTON — The April 4 rejection by US Army Materiel Command of a General Dynamics Land Systems protest disputing the fairness of the Armored Multi-Purpose Vehicle (AMPV) competition puts the ball squarely back into GD’s court, which has the option of lodging a more formal protest with the Government Accountability Office — a move that would halt all work on the program for weeks or even months.

 

On Feb. 14, GD filed a protest contending “the AMPV solicitation provides a competitive advantage” to competitor BAE Systems, since BAE “has years of Army test and performance data” on the M113 personnel carrier, which the competition has been launched to replace.

 

“In our view, the AMPV procurement process is not consistent with the Competition in Contracting Act of 1984, requiring a “full and open competition,” the company said in a statement.

 

These statements could indicate the company will file a protest with the GAO during the 10-day window that began when the initial protest was denied on April 4.

 

At issue is the fact that the Army wants competitors to incorporate parts from the Bradley fighting vehicle and the M113 in their AMPV designs, both of which are made by BAE. General Dynamics contends that it doesn’t have all of the relevant historical information on those parts to fully compete. The company has long said that it would submit a version of its eight-wheeled Stryker vehicle, of which the Army currently fields nine full brigades and a smaller Special Operations contingent.

 

BAE launched its own salvo on Friday afternoon, saying that it “is pleased” at the decision and that “cost savings, political expediency and business reasons do not justify putting soldiers’ lives at risk. The Army has had this solicitation in the works for two years and has adjusted requirements based on industry feedback to accommodate the broadest number of competitive offerings possible.”

 

On April 3, 10 members of Congress wrote a letter to the Pentagon’s top weapons tester, Frank Kendall, urging the Army to rewrite the five-month-old request for proposals. The lawmakers wrote that the Army should rework the program with a view toward “allowing for a mixed fleet of both track and wheeled vehicles” to meet the requirements for the competition.

 

In other words, the Army should split up the buy for 3,000 AMPVs between Stryker and Bradley variants.

 

The lawmakers also outlined the core reason for GD’s protests: the dearth of new ground vehicle programs in the Army’s near-term future.

 

“Given the intensely restrictive budget requirement the Army faces, the AMPV might be the only new vehicle entering the fleet for decades,” they wrote.

 

Rep. Ralph Hall, R-Texas, who represents the district that houses the Red River Army Depot — and its 4,500 jobs — which performs a great deal of work on Bradleys, issued a statement on Friday applauding the decision.

 

“No current vehicles meet the survivability, mobility, and reliability upgrades outlined in the Army’s competitive bid,” he wrote. The program “cannot be delayed a year or more by rehashing the multi-year bidding process.”

 

On March 4, Hall sent a letter to Defense Secretary Chuck Hagel pitching BAE’s AMPV bid as good for the local economy, saying that “if BAE Systems is awarded the contract, jobs will be protected at Red River Army Depot and additional jobs could be added.”

 US Army Modernization Focuses on Soldier

 

April 04, 2014 defense-aerospace.com

(Source: U.S Army; issued April 2, 2014)

 

Modernization Strategy Soldier-Focused In Lean Years

 

WASHINGTON --- Research, development and acquisition investments have declined 37 percent since the fiscal year 2012 budget planning cycle, said the G-8.

 

Historically, the research, development and acquisition, or RDA, account averaged about 22 percent of the Army's obligation authority. But for fiscal year 2015, the RDA account is at 17 percent or about $20 billion, Lt. Gen. James O. Barclay III told members of the House Armed Services Subcommittee on Tactical Air and Land Forces, today.

 

Yet, despite slashing RDA, "it's essential that the Army ensure every Soldier deployed is equipped to achieve decisive overmatch," he said, outlining the steps being taken.

 

To achieve decisive overmatch without much money, the Army is using incremental improvements to modernize critical systems, he explained. And new systems will be built "only by exception."

 

Additionally, he said the Army is divesting older systems like the Kiowa helicopter and "niche capabilities to decrease sustainment costs and generate more resources to invest in modernization and readiness."

 

In the area of science and technology, the Army is funding research on key areas that commercial corporations are ignoring, while reducing funding where private-sector S&T gains are being seen.

 

And finally, to maximize every dollar, the Army is procuring smaller quantities of systems and components.

 

Barclay admitted to lawmakers that the Army "is taking risks in its near-term modernization program," as it tries to balance that with readiness and modernization.

 

INDUSTRIAL BASE

 

Lawmakers expressed their concern that the organic industrial base would stagnate and lose workers as a result of the Army procuring smaller quantities of materiel, divesting systems and not buying new systems.

 

Addressing their concerns, Maj. Gen. Michael E. Williamson, military deputy to the assistant secretary of the Army for Acquisition, Logistics and Technology, enumerated steps the Army is taking as lawmakers tighten the purse strings.

 

Foreign military sales could keep some of the assembly lines running and talented professionals employed, he said, but that will only go so far.

 

"Not all sales come through," Williamson said, adding foreign sales can at times be unpredictable.

 

Acquisition reform is another area where improvements could be made, he said, pointing out that there are too many statutes and rules of where money can or cannot go and that adds to overhead costs associated with running facilities within the industrial base.

 

Army Materiel Command and the Office of the Assistant Secretary of the Army for Acquisition, Logistics and Technology, are now locating greater efficiencies, identifying "cost drivers," determining overhead and looking for opportunities, Williamson said.

 

Another way to save costs, while procuring in less quantities, he said, would be to team up with other agencies, not just sister services. For example, he said the Army might look at partnering with police and other security forces to procure body armor. Buying in quantity would drive down costs of the research as well as the procurement. Also, with more money in play, competition among vendors would be more likely.

 

Something else that could benefit the Army as well as the industrial base, he said would be using more multi-year programs. Depending on how the contracts are worded, multi-year might allow savings by creating leverage in negotiations.

 

Multi-year programs, of course, would need a predictable funding stream, which is something that hasn't been too predictable in recent years.

 

WEAPONS SYSTEMS

 

Barclay said the Army remains committed to continued funding of its mission-critical systems such as the Paladin Integrated Management System, double-V-hull Strykers, Warfighter Information Network-Tactical, and the Joint Light Tactical Vehicle.

 

He added that despite "a rocky start, [the Paladin Integrated Management System] is performing very well now."

 

If WIN-T is so important, why has the Army lowered funding for it and the Joint Tactical Radio System's Handheld, Manpack and Small Form Fit, asked a lawmaker.

 

Williamson replied that both WIN-T and HMS radio are critical to the warfighter but because of the declining budget, the Army has accepted some risk, "but not excessive risk."

 

Lower funding of those systems, he said, will mean fewer coming off the production lines, but those that do will be fielded first to the "most critical units" that are or could deploy.

 

Besides slowing production, he said some capability in the networks are being delayed, such as the WIN-T Increment 3 package which would have had enhanced bandwidth capability.

 

With respect to the networks, Barclay added that low funding is pushing the dates of procurements and deliveries to the right, but the Army is "not backing away from its commitment to the network and its overall importance."

 

One lawmaker commented that with the removal of the Apache helicopters from the National Guard, the Reserve Component is losing its teeth.

 

Barclay replied that active-component Apaches will still be "aligned with the National Guard" and its combat aviation brigades.

 

Why would the Guard's combat aviation brigades be called "combat" aviation brigades if the Apaches are being removed, the lawmaker pressed?

 

Black Hawk and Chinook helicopters, which the Guard has in its fleet, can and do perform combat missions, Barclay replied, adding that the decision to divest all of its Kiowa helicopters and remove Apaches from the Guard was done in consultation and after much analysis and that it's the "best we could do given the dollar amount given."

Kratos Defense & Security Solutions has been awarded a multi-million dollar subcontract for the modernisation of the US Army's CH-47F Chinook Avionics Trainers (CAT).

 

The deal, awarded by Usfalcon under the Aviation Applied Technology Directorate (AATD) SPOTS V contract, requires the company to perform upgrade services to four of the simulators currently located at the army's 128th Aviation Brigade in Fort Eustis, Virginia, US.

 

Specifically, this includes the aircraft product improvement programme one (PIP1), which will ensure concurrency of the simulators to the aircraft, as well as other product lifecycle and functional improvements, such as the networking of simulators to enable trainees to perform more advanced maintenance scenarios.

 

Kratos Training Solutions senior vice-president Jose Diaz said that the maintenance of the CH-47, which is a vital asset for troops, is critical to the army.

 

"Based on our detailed knowledge of these simulators, coupled with the use of our advanced software integration lab capability, device downtime will be minimised and student training will continue during the upgrade period," Diaz said.

 

Manufactured by Kratos, the CH-47F CAT is a high fidelity hands-on training system (HOTS) designed to train soldiers in fault isolation procedures (FIPs), remove and install (R/I) tasks, and system and subsystem familiarisation in a fully immersive physical environment.

 

Additional tasks include servicing and inspection, maintenance operational checks (MOCs), and component identification.

 

It is currently used to support heavy-lift helicopter maintenance training at the US Army's Aviation Logistics School (USAALS) in Fort Eustis.

U.S. Army Testing Fire Control System It Hopes Will Turn Average Shooter Into A Sniper

 

 

April 6, 2014. David Pugliese -  Defence Watch

 

Lance Bacon of the Army Times is reporting that the U.S. Army is testing a fire control system that turns an average shooter into a sniper in a matter of minutes.

 

More from the article:

 

The service recently bought six XactSystem precision-guided firearm kits. Each will be calibrated to the XM-2010 sniper rifle and the M248 Mod 1 rounds, which are standard-issue .300 Winchester Magnum.

 

School-trained snipers at various locations will spend up to four weeks testing functionality and effectiveness. The goal is to determine whether fire control systems enhance individual capabilities, said Lt. Col. Shawn Lucas, program manager for individual weapons at PEO Soldier.

 

“I can only squeeze so much more performance out of a rifle,” Lucas said. “Only so much more performance out of a bullet. I can only train a soldier so much. I have finite resources and time.

 

“However, for a relatively small investment, I can make a significant increase in probability of hit and overall effectiveness by making an investment in advanced fire control.”

DoD Sends Congress $36B Wish List, But Passage Unlikely

The US Air Force requested 12 General Atomics Reapers in the unfunded list.

 

Apr. 3, 2014 - By MARCUS WEISGERBER  - Defense News


 

WASHINGTON — The US military services have sent Congress wish lists that include $36 billion in priority items that were not included in the Pentagon’s 2015 budget proposal.

But actual passage of the lists seems unlikely.

The lists are very similar to the White House’s Opportunity, Growth and Security Initiative (OGSI), which includes $26 billion in defense items not included in the Defense Department’s $496 billion spending request.

Some of the overlap items include:

■ Two Air Force Lockheed Martin F-35 joint strike fighters ($372 million).

■ 10 Air Force Lockheed C-130Js, five MC-130J and five HC-130J variants ($1 billion).

■ 12 General Atomics Reapers ($192 million).

■ Eight Boeing P-8 maritime patrol aircraft ($1.1 billion)

■ Two Boeing CH-47 Chinook helicopters, according to Bloomberg (about $100 million).

■ 28 Sikorsky Black Hawk helicopters, according to Bloomberg (about $500 million).

■ One Northrop Grumman E-2D command-and-control plane ($146 million).

■ One Lockheed KC-130J tanker for the Marine Corps ($75 million).

But the service wish lists include other procurement items, including:

■ $200 million for the Air Force Combat Rescue Helicopter program.

■ $2.1 billion for 22 Boeing EA-18 Growler jamming aircraft for the Navy.

■ $720 million for 10 C-130J for the Air National Guard.

■ $1 billion for six F-35, five F-35Cs and one F-35B for the Marine Corps.

The wish lists also include tens of billions of dollars for upgrades, maintenance and construction projects, that have been reduced or deferred due to lower defense spending levels imposed by defense budget caps or cuts by sequestration.

Rep. Buck McKeon, R-Calif., chairman of the House Armed Services Committee, requested the lists from the services this year. The Army, Navy, Marine Corps, Air Force, Army National Guard and Air National Guard all sent the list to him this week. Defense News obtained all of the lists except the Army’s.

The top lines figures for each wish list are:

■ Army, $10.6 billion, according to Bloomberg.

■ Navy, $10.6 billion.

■ Marine Corps, $2.5 billion.

■ Air Force, $8 billion.

■ Army National Guard, $1.5 billion.

■ Air National Guard, $2.6 billion.

But the chances of any of the items in these wish lists and OGSI getting approved is slim, since defense spending is capped at $496 billion.

“It is not going to happen,” said Gordon Adams, a Stimson Center analyst who ran defense budgeting during the Clinton administration.

During a roundtable with reporters on Thursday, McKeon was asked what kind of chance the $26 billion OSGI had of passage. He made a “zero” gesture with his fingers.

“We already did the budget this year,” he said.

Lawmakers are unwilling to renegotiate the spending caps established in the two-year budget deal struck late last year by Rep. Paul Ryan, R-Wis., and Sen. Patty Murray, D-Wash., Adams said.

“This is political three-ring circus, but it’s not budgeting,” Adams said. “The thing that really concerns me about it is that it totally undermines planning discipline in the Pentagon.”

DoD submitted a five-year spending plan to Congress that exceeds the spending caps between 2016 and 2019 by $115 billion.

The wish lists submitted to Congress this week — called unfunded priorities or unfunded requirements — were a flashback to last decade when the services would send lawmakers lists totaling tens-of-billions of dollars.

At its high point, the Air Force submitted a $20 billion wish list of items desired by service brass, at a time when military spending, already at an all-time high.

Then-Defense Secretary Robert Gates truncated the lists substantially during his tenure at the Pentagon to the point where they were no longer produced in 2013.

Unlike in prior years, the National Guard submitted unfunded lists this year.

New York Army National Guard soldiers train at Camp Smith, N.Y. (Army)

New York Army National Guard soldiers train at Camp Smith, N.Y. (Army)

 

 

Apr. 3, 2014 - By PAUL McLEARY – Defense News

 

WASHINGTON — The US Army National Guard is asking Congress to find an extra $1.5 billion to meet its unfunded requirements in fiscal year 2015, primarily to fund training and operations, according to a copy of the list obtained by Defense News.

 

Due to budget cuts and the winding down of troop requirements in Afghanistan, the Guard was not funded for any brigade-sized Combat Training Center (CTC) rotations in 2015. The Guard, therefore, is requesting $45 million to send two brigades through to intensive operational training.

 

The active Army is being funded for 19 brigade CTC rotations in 2015, Army Secretary John McHugh told the Senate Armed Services Committee on Thursday morning. Until Congress offered some sequester relief in January, the Army was only planning on seven CTC rotations this year.

 

The biggest line in the Guard’s request also involves training. The service is requesting $480 million to “allow 3 BCTs [brigade combat teams] to achieve company level of readiness; 3 BCTs to achieve platoon levels of readiness … and all Functional/Multi-Functional units to achieve company level of readiness.”

 

The Guard has said that under the current budget cuts, its units would be able to train only to squad and company levels of readiness, while not being able to afford to train for complex operations, such as brigade-sized maneuvers with air and ground elements working in tandem.

 

The Guard is also asking for $137 million for depot maintenance, which is funded only to 33.6 percent of its requirement. “The increase improves funding to 48.83% for maintenance of aviation end items and spares HEMTTs, PLS, M915A3 Tractors, and M917 Dump Trucks to improve readiness and support an Operational Force,” the Guard wrote

Source: Pakistan Already Has US-Made MRAPs, New Deal in Works

Mine resistant ambush protected vehicles are loaded onto the USNS Pililaau in 2007 at the seaport of Charleston, S.C. (US Army)

 

Apr. 2, 2014 - By PAUL McLEARY  - Defense News

 

WASHINGTON — While controversy swirls over reports that Pakistan may receive some of the excess Mine Resistant Ambush Protected (MRAP) vehicles that the United States has sitting in Afghanistan, American and Pakistani officials are on the verge of completing a deal to send new and excess MRAPs to Islamabad, Defense News has learned.

The 160 vehicles, all of which would be the MaxxPro MRAP variant made by US manufacturer Navistar, would be a mix of new builds and some from US Army prepositioned stocks in Kuwait, according to a person familiar with the negotiations who is not authorized to speak for attribution.

While no formal notification of the deal has yet been sent to Congress since the last stages of the vetting process are still being completed, the official expected a notification to head to Capitol Hill by the end of this month.

The spat over the potential MRAP sale began in March when the Washington Post reported that the United States was considering giving Pakistan some MRAPs that the US didn’t want to pay to ship home once the mission in Afghanistan draws to a close. The report came at the same time as Marine Gen. Joseph Dunford, commander of the coalition and US Forces in Afghanistan, said there are more than 1,200 excess MRAPs in country.

For a while, US forces were literally shredding to bits the hulking MRAP infantry carriers that it doesn’t want to pay to bring home, but Dunford has since put a halt to that program while final decisions on the ultimate fate of the fleet are being made.

The holdup on the deal for the 160 MRAPs centers around a congressionally mandated human rights vetting process that all US foreign training and equipping programs must undergo.

Known as the “Leahey Amendment” after the bill’s sponsor, Sen. Patrick Leahey of Vermont, the law stipulates that US forces cannot train or equip foreign military or police units that have been accused of human rights abuses.

The 160 MRAPs would be split among the branches of the Pakistani armed forces. Although specific army and air force units have been identified and vetted, the Pakistani Navy has yet to submit all of the required information, according to the official.

While it hasn’t been reported previously, the Pakistani armed forces have already been supplied with 22 MRAPs — 20 MaxxPro’s along with two “haulers” to move them if damaged — under a now-canceled State Department program known as the Pakistan Counterinsurgency Capability Fund. The vehicles were drawn out of the US Army’s existing stock in Kuwait.

The fund was axed in the US government’s fiscal 2014 budget.

The State Department and the US Embassy in Islamabad have been tying themselves in rhetorical knots over the past week trying to explain the situation over the potential MRAP transfer, all without giving specifics or mentioning the MRAPs already sent to Pakistan or the deal currently in the works.

On March 31, the Islamabad embassy issued a statement confirming that Pakistan has requested “a variety of Excess Defense Articles (EDA). The U.S. is currently reviewing Pakistan’s request.” In what appears to be a nod to the pending deal, the embassy added that “if approved, this EDA is likely to be sourced from U.S. stock outside Afghanistan.”

The State Department weighs EDA requests on a “case-by-case basis taking into consideration a range of factors including the need of potential recipients, regional security dynamics, how the recipient nations intend to use the equipment and the ability of an EDA recipient to sustain the equipment,” the embassy said. ■

Support: AVCATT Flies The Silicon Skies

 

April 2, 2014: Strategy Page

 

As the U.S. Army retrains its forces to handle conventional war, what the military calls “near-peer” (against someone who has similar weapons and abilities) combat it is finding that computer simulators make it possible to retrain quickly and inexpensively. This is especially true with helicopters, which operate quite differently in near-peer combat than when fighting irregulars and Islamic terrorists. Pilots operate flight controls, sensors and weapons differently and relearning near-peer procedures is very expensive if you do it in the air. It’s also quite dangerous, since one of the things you have to practice is operating in near-peer mode at night, in bad weather or under attack (or all three at once). That’s nearly as scary and is over 90 percent cheaper when done on a simulator.

 

The primary American helicopter simulator is AVCATT (Aviation Combined Arms Tactical Trainer). This is a mobile (two trailers) system that can emulate AH-64A/D 6.1/10, OH-58D, UH-60A/L and CH-47D. AVCATT comes with terrain databases for the U.S. Army NTC (Fort Irwin), Grafenwoehr-Hohenfels training area in Germany, Iraq, Fort Hood (Texas), Afghanistan and Korea. Multiple AVCATT’s can communicate with each other to allow multiple crews to train together. Since all the trainee data is captured electronically it’s possible to give very valuable and detailed after-action critiques.

 

 AVCATT has been around since 2003 and that first version proved invaluable in converting crews from decades of near-peer combat training to handling less well armed and organized opponents. The original AVCATT cut the cost of pilot training some 80 percent by using the same electronic and display components found in PCs and video games. In addition to saving a lot of money, using off-the-shelf components makes is possible to create portable flight simulators. This is important for several reasons. For one thing, not every helicopter units follows the same training schedule, so it's a major advantage if the simulators could be easily moved from air base to air base. It's also important to get simulators to a war zone so pilots can practice battle tactics. There was also a special AH-64 flight simulator which used full fidelity (almost like the real thing) graphics.

 

The AVCATT, however, takes the off the shelf components, and mobility, trends a lot farther. Housed in two standard, 40 foot trailers, the system contains;

 

- Six Reconfigurable Manned Modules (simulated cockpits for pilot and copilot). These do not have the fidelity of older simulators, but are sufficient for experienced pilots to work out tactics in cooperation with other pilots, and against a realistic enemy. What makes these work in 2003 was the photo-realistic graphics then widely available from off-the-shelf PC video cards. Running at about $300 each, these cards provided the graphics power of graphics “systems" from the 1990s ago that cost about a million dollars each.

 

- A Battle Master Control (BMC) Station. This is the officer who runs the training exercise. He, or she, must be cruel, but fair.

 

- A Semi-Automated Forces (SAF) Operator. The bad guys are played by software generated aircraft and ground units. But as the name SAF implies, a human operator can intercede to avoid the silliness that software generated NPCs (Non-Player Characters) are often guilty of if left to their own devices.

 

- Four Role Player Stations are four people who will provide realistic spoken communications over the radio. Eventually these will be replaced by software, but at the moment it's more reliable to use people.

 

- Eight Tactical Operations Center (TOC) Stations. Similar to the Role Player Stations, but the TOC people usually assume the same role (unit commander, air controller, Etc.) for the entire exercise.

 

- An After Action Review (AAR) Station. This is a miniature theater that takes up nearly half of one trailer. It seats 20 and has large displays and a sound system on one end. The beauty of this set up is that, right after the exercise, the trainees and some of the staff can go to the "AAR Station" and see instant replay, with appropriate commentary, of what they did right, or wrong.

 

The first AVCATT cost about three million dollars for each two trailer set and since then have gotten more expensive but a lot more powerful. For example the current model uses helmet mounted displays so wherever the trainee looks they see what they would see in an actual helicopter. AVCATT was also built to plug and play with other army combat simulators, taking networked gaming to places civilian gamers can only dream about.

 

The U.S. Army had, during the 1990s largely abandoned milspec (military specifications) in purchasing electronics for use in their simulators. Since the 1990s, the army has taken full advantage of the growing power of PCs and, especially, PC graphics. Milspec components can take years to get approved. But in the last few decades, noting how civilian products are developed faster, and often are more reliable than milspec equivalents, and a lot cheaper, the Department of Defense has been more readily giving permission to develop equipment that does not contain milspec parts. The markedly lowered the cost of things like simulators, produced faster delivery times and greater portability and has made the non-milspec pretty much a standard in some areas of military equipment. And in other cases, troops are taking their laptops, PDAs and other off-the-shelf electronics to take care of business in the combat zone. This has been going on for decades, a sort of unauthorized field testing of new gear. Strictly forbidden of course, as using this unauthorized stuff could get someone killed. But so far, the non-milspec gadgets appear to have saved a lot more lives than they have endangered.
