WASHINGTON, 12 août - RIA Novosti

 

Des avions militaires américains ont largué un cinquième lot d'eau et de vivres destinés aux civils bloqués dans les monts Sinjar (nord de l'Irak) par les djihadistes de l'Etat islamique,  a annoncé mardi le Pentagone dans un communiqué.

 

"Un C-17 et trois avions cargo C-130 ont largué 76 cargaisons de vivres qui fourniront de la nourriture et de l'eau pour des milliers d'Irakiens piégés sur les monts Sinjar", a indique le communiqué.

 

Selon le Pentagone, les Etats-Unis ont fourni depuis jeudi soir "plus de 85.000 repas et plus de 75.500 litres d'eau potable" aux membres de la minorité yézidi pourchassés par les djihadistes.

 

Appuyé par des sunnites irakiens et par d'anciens militaires de l'armée de Saddam Hussein, le groupe terroriste Etat islamique a envahi une vaste région irakienne englobant les provinces de Ninawa, de Salah ad-Din et d'Al-Anbar.

 

Le 29 juin dernier, l'EI a annoncé la création d'un "Califat islamique", le titre de calife étant attribué au chef de file de ce groupe djihadiste, Abdullah Ibrahim al-Samarrai, connu également sous le nom d'Abou Bakr al-Baghdadi.

 

Dans la nuit de jeudi à vendredi, le président américain Barack Obama a autorisé des frappes aériennes ciblées en Irak "pour aider les forces irakiennes qui se battent pour protéger les civils".

Sailors prepare weapons to upload onto an aircraft on the flight deck of the aircraft carrier USS George H.W. Bush (CVN 77)

 

August 08, 2014 by Frederic C. Hof * - atlanticcouncil.org

 

On August 7, President Barack Obama authorized both airstrikes and humanitarian relief in response to attacks launched by the ersatz caliphate of the criminal enterprise calling itself the Islamic State (IS). The proximate cause of US military intervention is a looming humanitarian catastrophe centering on a vulnerable Iraqi minority (the Yazidis) seeking safety from IS on the slopes of a mountain. But legal cover for the action was provided by the president’s assertion that IS forces “have neared the city of Erbil [the capital of the Kurdish Regional Government], where American diplomats and civilians serve at our consulate and American military personnel advise Iraqi forces.” This decision to intervene in the face of IS terror and mass murder is appropriate and welcome. Inevitably, however, those who have called for a similar humanitarian intervention in Syria—where the depredations of the Assad regime and IS alike dwarf what is happening in Iraq—will wonder why Iraq and why not Syria.

Le Pentagone ne compte pas étendre ses frappes à d'autres régions de l'Irak

 

11 août 2014 Romandie.com (AFP)

 

Washington - Le Pentagone a assuré lundi qu'il ne comptait pas étendre ses frappes aériennes hors de la région du nord de l'Irak où ses forces aériennes visent les combattants de l'Etat islamique.

 

Depuis que le président Barack Obama les y a autorisés jeudi, les chasseurs et drones américains ont effectué 15 frappes aériennes contre les insurgés de l'Etat islamique, a déclaré le général William Mayville, un haut responsable du département américain de la Défense, lors d'une conférence de presse, sans toutefois préciser les dommages occasionnés aux combattants.

 

Nous n'avons pas pour projet d'étendre la campagne au-delà des opérations de défense actuelles, a-t-il dit.

 

Il a estimé entre 50 et 60 le nombre de missions effectuées chaque jour par les appareils américains au-dessus du nord de l'Irak, en additionnant les missions humanitaires et les frappes aériennes.

 

Les frappes ont contribué à freiner l'avance des forces de l'Etat islamique autour de Sinjar et dans l'ouest d'Erbil, la capitale du Kurdistan irakien, a expliqué le général Mayville, soulignant qu'il s'agissait en premier lieu de défendre le personnel diplomatique américain en poste à Erbil.

 

Les frappes aériennes sont accompagnées de largages humanitaires destinés aux dizaines de milliers de chrétiens et Yazidis pourchassés par les insurgés sunnites. Le Pentagone et les forces britanniques ont ainsi parachuté environ 60.000 litres d'eau et 75.000 repas aux réfugiés, selon le haut gradé américain.

 

Pour l'instant, notre objectif est de fournir une aide immédiate à ceux qui souffrent, a expliqué le général Mayville.

WASHINGTON, 11août - RIA Novosti

 

Des avions militaires américains ont largué de nouvelles cargaisons d'eau et de vivres destinées aux civils bloqués dans les monts Sinjar (nord de l'Irak) par les djihadistes de l'Etat islamique,  a annoncé lundi le Pentagone dans un communiqué.

 

"Un C-17 et trois avions cargo C-130 ont largué 88 cargaisons de vivres qui fourniront de la nourriture et de l'eau pour des milliers d'Irakiens piégés sur les monts Sinjar", a indique le communiqué.

 

Selon le Pentagone, les Etats-Unis ont fourni depuis jeudi soir "plus de 74.000 repas et plus de 56.780 litres d'eau potable" aux membres de la minorité yézidi pourchassés par les djihadistes.

E-11A - Battlefield Airborne Communications Node (BACN)

E-11A - Battlefield Airborne Communications Node (BACN)

 

8 August 2014 airforce-technology.com

 

Northrop Grumman has been awarded a contract to continue the operation and support of the US Air Force's (USAF) battlefield airborne communications node (BACN) system.

 

Under the $89.7m contract's terms, the company will extend operational support of the BACN payloads in support of overseas contingency missions until June 2015.

 

Equipped with an airborne executive processor (AEP), BACN is a forward-deployed network-centric enterprise information server, developed to enable data sharing between different battlefield communications systems using a suite of computers and radio systems.

 

The high-altitude BACN payloads are integrated onto four E-11A Bombardier Global Express BD-700 aircraft and three EQ-4B Block 20 Global Hawk unmanned aerial vehicles deployed in support of Operation Enduring Freedom in Afghanistan.

 

Northrop Grumman Information Systems communications division vice-president and general manager Jeannie Hilger said: "BACN is making such a tremendous difference for our warfighters that it is regarded as indispensable for mission success.

 

"The amount of positive feedback BACN receives from our warfighters is a testament to the critical support BACN currently provides and an inspiration to continuously enhance the system's capabilities."

 

The BACN also provides an advanced airborne communications capability to commanders and troops, as well as enhancing situational awareness and extending voice communications.

 

Northrop expects BACN to serves as a persistent high-altitude gateway in the joint aerial layer network (JALN) to offer secure communications to disadvantaged soldiers and network connectivity across the theatre.

 

The JALN would be designed to expand on existing communications networks and capabilities and links ground, space and airborne military assets.

 

Northrop serves as prime contractor for the EQ-4B Global Hawk UAV and the development, fielding and maintenance of the BACN system, and received the first BACN contract from the US Air Force Electronic Systems Center in April 2005.

Pease ANGB Selected to Receive KC-46A Pegasus

 

Aug 6, 2014 ASDNews Source : US Air Force

 

Air Force officials announced Aug. 6, Pease Air National Guard Base, New Hampshire as the Air Force's first Air National Guard-led KC-46A Pegasus main operating base.

 

"The KC-46A Pegasus aerial tanker remains one of our top acquisition priorities. Making a final basing decision is an important step in recapitalizing the tanker fleet," said Secretary of the Air Force Deborah Lee James. "We will begin to replace our aging tanker fleet in 2016, but even when the program is complete in 2028 we will have replaced less than half of the current tanker fleet and will still be flying over 200 half-century-old KC-135s."

Warplanes: Super Reaper OrderedWarplanes: Super Reaper Ordered

 

August 9, 2014: Strategy Page

 

The U.S. Air Force has ordered 38 MQ-9 Reaper ER UAVs. This is an upgrade of the original MQ-9 design that allows longer endurance (up to 35 hours) by carrying two fuel tanks (one under each wing) that use a new fuel management system that ensures fuel is taken from the main fuel tank and the two external tanks in such a way that the aircraft does not become unbalanced. The new version also has the engine modified so that it can generate more power on takeoff, enabling the MQ-9 to achieve heavier takeoff weight. The ER version is also getting 20 percent longer wings. Since the wings already carry fuel, this will help increase fuel and endurance to about 42 hours.

 

The original MQ-9 Reaper looked like the earlier 1.2 ton MQ-1 Predator but was larger. The 4.7 ton MQ-9 is an 11.6 meters (36 foot) long aircraft with a 21.3 meters (66 foot) wingspan. It has six hard points and can carry 682 kg (1,500 pounds) of weapons. These include Hellfire missiles (up to eight), two Sidewinder or two AMRAAM air-to-air missiles, two Maverick missiles, or two 227 kg (500 pound) smart bombs (laser or GPS guided). Max speed is 400 kilometers an hour, and max endurance is priginally 15 hours. The Reaper is considered a combat aircraft, to replace F-16s or A-10s in many situations. Most of the 104 Reapers built so far have been for the U.S. Air Force and since introduced in 2007 these Reapers have flown over two million hours.

Eielson AFB Selected As Preferred Alternative for 1st Overseas-Based F-35As

 

Aug 7, 2014 ASDNews Source : US Air Force

 

Air Force officials announced Aug. 7 that Eielson Air Force Base, Alaska, was selected as the preferred alternative to host the first F-35A Lightning II squadrons in the Pacific area of responsibility.

Eielson was selected due to its ability to support the mission, economic factors and environmental considerations.

"Basing the F-35s at Eielson (AFB) will allow the Air Force the capability of using the Joint Pacific Alaska Range Complex for large force exercises using a multitude of ranges and maneuver areas in Alaska," said Secretary of the Air Force Deborah Lee James. "This, combined with the largest airspace in the Air Force, ensures realistic combat training for the DOD."

As Strikes Begin in Iraq, Many Options for Pentagon

Although considered less pinpoint than its fast-jet cousins, the A-10 could also play a role in what may be its last military campaign before the Air Force retires the plane. Proponents of the plane say its ability to get low to the ground could help prevent civilian casualties in a situation where the insurgent population may be mixing with non-combatants. (US Air Force)

 

Aug. 8, 2014 - By AARON MEHTA – Defense News

 

WASHINGTON — The US campaign against a militant group that has taken control of huge chunks of Iraq has begun. Despite the near-total withdrawal of US ground troops from the country in the past five years, the Pentagon has many options for more airstrikes — and many options on deployment, given the air dominance US forces will have.

 

On Friday morning, Pentagon officials said a pair of F/A-18 Super Hornets had bombed artillery belonging to Islamic State in Iraq and the Levant (ISL). This was the first US strike against the group, and few expect it to be the last.

 

“We’re talking a very, very permissive operating environment, at least in the air,” said Mark Gunzinger, a former DoD official and now an analyst with the Center for Strategic and Budgetary Assessments in Washington. “We have to be concerned about low-altitude MANPADs, but it’s pretty permissive, so that does open up how they might posture forces in an actual concept of operations.”

 

The US Air Force has a variety of assets in the region, Lt. Col. Tadd Sholtis, a spokesman for US Air Forces Central Command (AFCENT), said in a statement provided by the Air Force Press Desk. That statement reflects standing information about AFCENT forces and was not newly drafted.

 

AFCENT has a wide area of responsibility, and can draw on any of its fighters (A-10, F-15E, F-16, F-22), bombers (B-1), surveillance craft (E-3, E-8, RC-135), support vehicles (C-17, C-130, KC-10, KC-135) and unmanned systems (MQ-1, MQ-9, RQ-4.)

 

“That steady-state force includes approximately 90 US Air Force fighters, bombers or other strike aircraft based in the AOR, including MQ-9 Reaper UAVs that can be more heavily armed,” Sholtis said in a statement. “There are approximately 190 other aircraft in that steady-state force supporting ISR (including MQ-1 Predator UAVs), command-and-control, tanker or airlift missions throughout the AOR.”

 

It is entirely possible that a sustained campaign would be launched from outside Iraq, relying on long-distance capabilities, Gunzinger noted.

 

“Since we don’t have a large footprint in country and we don’t have a lot of combat aircraft in country I think anything more than small strikes and raids, if it’s a more concerted effort, will rely heavily on longer-range capabilities,” he said. “This could be a very different kind of an air campaign than we’ve done in the past, depending on the size and duration.”

 

The mission in Iraq is now threefold. The first is gathering intelligence on the situation, which the US has been doing for some weeks now.

 

Speaking July 29, Gen. Mike Hostage, the head of Air Combat Command, said he has been using a mix of manned and unmanned systems for intelligence, surveillance and reconnaissance (ISR) missions in Iraq.

 

“It’s what we call nontraditional ISR,” Gen. Mike Hostage, the head of US Air Force Air Combat Command, said. “We’re using fighter aircraft that have ISR capacities, like targeting pods, and things that give us a lot of awareness on what’s going on, on the ground.”

 

Hostage did not elaborate on what fighters were doing what, but the F_15, F-16, F-22 and A-10 all have ISR capabilities in one form or another.

 

The second part of the mission is delivering supplies to Iraqi and Kurdish forces trying to fight back against the Islamic States.

 

A senior defense official told reporters that the first humanitarian drop came Thursday evening over Kurdish territory in northern Iraq. That included two C-130 and one C-17 cargo planes, which were escorted by two F/A-18 Super Hornets, the official said.

 

 

The third arm of the operation, and the one most likely to gather the headlines, is the air strike component.

 

The F-15E, F-16, F-22 and F/A-18 all have precision weaponry that can be targeted to take out enemy equipment, while still traveling at high altitude and fast speeds to stay clear of enemy fire. Another option is the B-1 bomber, which has also been used for precision strike over the last 13 years in Iraq.

 

Although considered less pinpoint than its fast-jet cousins, the A-10 could also play a role in what may be its last military campaign before the Air Force retires the plane. Proponents of the plane say its ability to get low to the ground could help prevent civilian casualties in a situation where the insurgent population may be mixing with non-combatants.

 

The unmanned MQ-9 Reaper is also a likely contributor. Its cousin, the MQ-1 Predator, is another system that may see its last combat operations, as it is slowly being phased out of the service.

 

Unmanned systems have the added benefit of keeping US airmen out of danger.

 

“Should we lose one or two of those unmanned systems, you don’t have a need of [combat search and rescue] forces to go in and extract pilots,” Gunzinger noted.

 

During the Libyan campaign in March 2011, both B-1Bs and B-2 Spirit stealth bombers were sent on long-distance sorties to attack targets instead of being forward deployed.

 

Three B-2s from the 509th Bomb Wing, Whiteman Air Force Base, Mo., flew 25 hours nonstop from their home base to drop 45 2,000-pound Joint Direct Attack Munitions to destroy military aircraft and facilities at Ghardabiya, Libya.

 

Also, two B-1B Lancers from Ellsworth Air Force Base, S.D., left their home base to assist in enforcing the no-fly zone over Libya, returning three days later after hitting almost 100 targets in North Africa.

US Air Force, Northrop Grumman Celebrate 25th Anniversary of B-2 Stealth Bomber's First Flight

 

PALMDALE, Calif., July 17, 2014 Northrop Grumman

 

For several goose bump-filled minutes today at U.S. Air Force Plant 42, it was July 17, 1989, all over again.

 

Just as they had on that historic day 25 years ago, several thousand Northrop Grumman Corporation (NYSE:NOC) employees, civic leaders and Air Force personnel stood along the company's southern fence line in Palmdale to watch a B-2 stealth bomber taxi onto Runway 25.

As the tailless, bat-wing-shaped jet made its final turn and paused, its four General Electric engines began to roar. Slowly at first, then faster and faster, the B-2 thundered down the runway. As it lifted off and rose gracefully into the western morning sky, so too did the cheers of the adoring crowd, many of whom had started their careers on the B-2 program during its 30-plus-year history.

Northrop Grumman is the prime contractor for the Air Force's B-2 bomber, a key component of the nation's long range strike arsenal, and one of the most survivable aircraft in the world.

"For the past 25 years, the B-2 has been, and today continues to be, one of the most decisive and effective weapons systems for influencing our adversaries and defending America's interests around the globe," said Brig. Gen. Glen D. VanHerck, commander of the 509th Bomb Wing, Whiteman Air Force Base, Missouri. "The B-2's ability to provide strategic deterrence capabilities to our nation's leaders -- and when deterrence fails, to deliver global power options -- is a testament to the talents of those who designed and built the B-2, and to the daily sacrifices of the airmen who fly, maintain and support the fleet."

Northrop Grumman conducted its 25th anniversary ceremony today on the tarmac near the facilities where every B-2 bomber was built and where every B-2 comes for a periodic wingtip-to-wingtip overhaul known as programmed depot maintenance.

Set against the backdrop of an operational B-2, the program included remarks by former Los Angeles Dodgers manager Tommy Lasorda; Bruce Hinds, former Northrop Grumman chief B-2 test pilot, who commanded first flight; Air Force Brig. Gen. Steven L. Basham, who co-piloted the first B-2 combat mission, and Duke Dufresne, a former B-2 program manager for Northrop Grumman and currently sector vice president, Operations for its Aerospace Systems sector.

"The B-2's maiden flight from Palmdale to Edwards Air Force Base lasted just over two hours, but it changed forever the tenor of long range strike and international diplomacy," said Tom Vice, corporate vice president and president, Northrop Grumman Aerospace Systems. "Today, the bomber personifies Northrop Grumman's innovation and imagination, and provides an enduring symbol of the company's commitment to the brave men and women who defend our nation."

Following takeoff, the B-2 pilots thrilled the audience by circling back over the Plant 42 at low altitude and performing a ceremonial "wing wave" for the crowd.

The B-2 can carry both conventional and nuclear weapons. It is the only aircraft that combines stealth, long range, large payload and precision weapons delivery in a single platform. The B-2's unique capabilities allow it to penetrate an enemy's most sophisticated defenses and put at risk its most heavily defended targets.

Farnborough : F-35's UK air show appearance ruled out

 

15.07.2014 By: Craig Hoyle - FG

 

The dramatic lifting yesterday of a grounding order on the Lockheed ¬Martin F-35 briefly raised hopes that the stealthy type could make a transatlantic dash to the show, but was followed by late news from Washington that the Joint Strike Fighter will not be able to visit the UK.

An airworthiness board convened by the US Air Force and US Navy on Monday had approved a return to flight order for the F-35 fleet, but under certain limitations. These included a new inspection interval for the Pratt & Whitney F135 engine, and a restricted flight envelope. To remain in place until the root cause of a late June fire has been identified, the measures effectively made the trip to the UK impossible.

Jul. 11, 2014 By Stephen Trimble - FG

 

Washington DC - The US Air Force has launched the competitive phase of the classified long range strike bomber by issuing a request for proposals, with Northrop Grumman and a Boeing/Lockheed Martin team poised to compete for a contract to develop and build 80-100 aircraft over the next two decades.

Details of the air force’s requirements for the new bomber are classified, and service officials are unlikely to provide more updates until a scheduled contract award in the second quarter of 2015.

“It will be an adaptable and highly capable system based upon mature technology,” says secretary of the air force Deborah Lee James.

Air force officials also have said the new bomber, also called the LRS-B, will enter service as a manned aircraft with a target unit price of $550 million. As the first new US bomber launched since the Northrop Grumman B-2A, the LRS-B is expected to replace a fleet of 76 Boeing B-52H and possibly a portion of the supersonic Rockwell B-1B fleets. A fleet of 20 B-2As will remain in service and complement the LRS-B.

Multiple birdstrike downed Pave Hawk, USAF concludes

 

Jul. 10, 2014 By David Learmount - FG

 

London - A multiple birdstrike caused the 7 January fatal crash of a US Air Force Sikorsky HH-60G Pave Hawk helicopter over the UK east coast, accident investigators have determined.

The crew and the aircraft belonged to the USAF’s 56th Rescue Squadron, operating from RAF Lakenheath, UK.

According to a report into the accident compiled by the service, the crew was on a training sortie described by the USAF as “a night-time rescue scenario of a downed F-16 pilot on grass-covered marshland near Cley-next-the-Sea”.

Following the birdstrike by a flock of geese the aircraft went out of control and crashed, causing the death of all four on board.

L'armée américaine a décidé de clouer au sol la totalité de ses chasseurs F-35 pour inspecter les moteurs après un incendie à bord d'un appareil la semaine dernière en Floride.

 

Décidément les déboires du F-35 ne s'arrêteront jamais. L'armée américaine a décidé de clouer au sol la totalité de ses chasseurs F-35 pour inspecter les moteurs après un incendie à bord d'un appareil la semaine dernière en Floride, énième déconvenue subie par ce très coûteux programme. L'Armée de l'Air et la Marine ont donné jeudi des directives pour clouer au sol tous les appareils après l'incendie du 23 juin à la base aérienne d'Eglin. La cause de cet incident n'est pas connue pour le moment et fait l'objet d'une enquête.

Dans un communiqué, le Pentagone déclare qu'aucune cause précise n'a pu être décelée pour expliquer cet incendie qui s'est produit au moment où le pilote, qui n'a pas été blessé, se préparait au décollage. "Des contrôles supplémentaires des moteurs des F-35 ont été requis, et le retour en vol sera déterminé sur la base du résultat des contrôles et l'analyse des informations recueillies", a déclaré un porte-parole du Pentagone, le contre-amiral John Kirby, dans un court communiqué. Le F-35 est construit par Lockheed Martin, son moteur par Pratt & Whitney, une filiale d'United Technologies Corp.

 

 

Le F-35 à Farnborough ?

Le F-35 doit normalement participer à des salons aériens en Grande-Bretagne (le Royal International Air Tattoo qui début le 11 juillet et le Farnborough International Airshow qui débute le 19 juillet) mais le Pentagone a indiqué que la décision finale serait prise la semaine prochaine.

Cet incendie n'est que le dernier d'une série de problèmes techniques et de retards pour le Joint Strike Fighter (JSF), présenté comme une merveille technologique mais qui a souffert d'une série de contretemps avec un budget qui a explosé pour atteindre plus de 390 milliards de dollars, pour 2.443 avions, et quelque sept ans de retard. Ce programme d'armement est le plus coûteux jamais produit aux États-Unis.

USAF Releases Reaper UAV Accident Report

 

July 1, 2014 defense-unmanned.com

(Source: US Air Force; issued July 1, 2014)

 

MQ-9 Reaper Accident Report Released

 

LANGLEY AFB, Va. --- A series of system malfunctions led to the crash of an MQ-9 Reaper into Lake Ontario, New York, Nov. 12, 2013. The crash occurred approximately 35 miles southwest of Fort Drum, New York according to an Air Combat Command Accident Investigation Board report released today.

 

The mishap aircraft and mishap aircrew were assigned to the 17 4th Attack Wing, Hancock Field Air National Guard Base, New York. The aircraft, valued at $10.6 million, was destroyed on impact; there was no damage to private property.

 

After the MQ-9 departed Wheeler-Sack Army Airfield, New York, for the Oswego

Military Operating area to conduct a routine tra ining mission, control of the MQ-9 was turned over from the launch recovery element (LRE) aircrew to the mission control element aircrew (MCE) at Hancock Field. During the training mission, the MCE aircrew noticed a series of warnings indicating a partial failure in the MQ-9's onboard GPS and inertial navigation system.

 

In response, the MCE aircrew at Hancock Field initiated the appropriate emergency checklist and informed the LRE aircrew of the situation. While the MCE aircrew was in the process of returning the MQ-9 to Wheeler-Sack Army Airfield, the aircraft lost link with the MCE aircrew and began to fly its pre programmed contingency return-to-base flightpath on its own. This pre-programmed flightpath allows the aircraft to return to base via a series of waypoints designed to safely avoid populated areas and potential obstructions.

 

The MCE aircrew followed the checklist instructions and disabled their command link to the aircraft to enable the LRE aircrew to attempt to gain control. While the LRE aircrew was initiating the link through their ground data terminal transmitter, the MQ-9 suffered an additional failure in its GPS and inertial navigation system. A few seconds later, the aircraft began an autopilot turn to the right that inverted the aircraft and eventually led to an unrecoverable flat spin. Shortly thereafter, the MQ-9 impacted Lake Ontario and was destroyed.

 

The accident investigation board president found by clear and convincing evidence that the cause of the aircraft crash was multiple failures within the MQ-9's GPS and inertial guidance system, in conjunction with that system passing invalid flight control data to the aircraft's autopilot system.

F-35A sustains fire damage during aborted take-off (23 jun.)

 

23 Jun 2014 By: Stephen Trimble - FG

 

A Lockheed Martin F-35A was damaged on 23 June after a fire erupted in the aft section of the fuselage during a take-off attempt from Eglin AFB, Florida, says a base spokeswoman.

The pilot aborted the take-off attempt due to the fire and exited the aircraft without injury, she says. Further details have not been released.

Emergency crews responded to the fire, which was reported at 09:15, and used foam to extinguish the flames, the spokeswoman says.

The cause of the fire is now under investigation.

GMD System Succeeds in Intercept, Fails to Satisfy Staunch Critics

 

June 27, 2014 by Abel Romero - missiledefensereview.org

 

This Sunday the Missile Defense Agency (MDA) along with U.S. Air Force 30th Space Wing, the Joint Functional Component Command, Integrated Missile Defense, U.S. Northern Command and the U.S. Navy conducted its first successful test of the Ground Based Midcourse Defense (GMD) system since 2008. The test is a major milestone in proving that the GMD is a viable option for the protection of the U.S. homeland from a limited ballistic missiles attack. Yet despite the success of the test, stubborn critics of the system refuse to acknowledge the advances made and the nature of the threat. The national missile defense system is a complicated engineering feat that demands regular testing. While intercept failures may be discouraging, it is important to note that the data collected presents an opportunity to correct the issues that caused those failures. While some would call the threat of a ballistic missile attack by North Korea “exaggerated”, there is currently no reliable way to measure just how advanced that threat is. Failing to plan for the worst could prove disastrous.

Sikorsky Awarded U.S. Air Force Contract to Develop New Combat Rescue Helicopter

 

June 26, 2014 Sikorsky Aircraft

 

Stratford, Connecticut - Sikorsky Aircraft, a subsidiary of United Technologies Corp. (NYSE:UTX), has been awarded a U.S. Air Force contract to develop new combat search and rescue helicopters. Sikorsky will develop a derivative of the UH-60M BLACK HAWK model for the Air Force’s rescue mission.


The award of an estimated $1.28 billion Engineering & Manufacturing Development (EMD) contract includes development and integration of the rescue mission systems; delivery of four Combat Rescue Helicopters; as well as seven aircrew and maintainer training systems. Initial training of Air Force aircrew and maintainers and five Combat Rescue Helicopters are also expected to be delivered by 2020, once additional aircraft and training options are exercised. This contract is the first step in the eventual production and fielding of up to 112 aircraft with a potential value of approximately $7.9 billion. Eventual production quantities would be determined year-by-year over the life of the program, based on funding allocations set by Congress and the U.S. Department of Defense acquisition priorities.

“We are honored that the Air Force has selected Sikorsky to develop and build the new Combat Rescue Helicopter,” said Sikorsky President Mick Maurer. “Since 1943, Sikorsky has proudly provided the combat rescue helicopter platform to enable the Air Force to perform one of its most important and sacred missions – bringing our downed service members home safely. I’m tremendously pleased that we will continue to do so for years to come.”

The Air Force announced in 2010 that it would replace its aging HH-60G PAVE HAWK helicopters. Sikorsky, joined by Lockheed Martin as the major subsystems supplier, offered a UH-60M derivative to replace the venerable PAVE HAWK, also made by Sikorsky, as the Air Force’s new Combat Rescue Helicopter. The aircraft features increased internal fuel capability, compared with today’s HH-60G helicopter, thereby giving the CRH-60 the required range, while increasing its internal cabin space.

Like the UH-60M helicopter, the aircraft will feature T700-GE-701D engines, composite wide-chord main rotor blades, and fatigue- and corrosion-resistant machined aero-structures to sustain maneuverability at high density altitudes.

“We are proud to expand our long-standing relationship with the U.S. Air Force and Sikorsky, providing a new aircraft system capable of performing the vital personnel recovery missions, including combat rescue and casualty evacuation,” said Dale Bennett, executive vice president of Lockheed Martin’s Mission Systems and Training business.

Sikorsky has produced more than 700 H-60M BLACK HAWK helicopters for the U.S. government and militaries worldwide, since production aircraft deliveries began in 2007.

 

Sikorsky Aircraft Corp., based in Stratford, Connecticut, is a world leader in helicopter design, manufacture, and service. United Technologies Corp., based in Hartford, Connecticut, provides a broad range of high technology products and support services to the aerospace and building systems industries.

L'US Air Force met l'accent sur le développement des drones

Le démonstrateur de drone de combat furtif Phantom Ray de Boeing fait la taille d'un avion de chasse.

 

24/06/2014 Par Julien Bergounhoux

 

Dans un document détaillant son programme de développement de drones, baptisé RPA Vector, l'Armée de l'air américaine révèle l'importance que les drones ont acquis au sein de la stratégie militaire au cours des dernières années, et la place proéminente qu'ils auront dans la guerre du futur.

 

L'Armée de l'air américaine travaille à l'élaboration d'une génération de drones constituant une véritable flotte à part entière. A terme, ces aéronefs sans pilote à bord ou avec pilote optionnel seront amenés à progressivement remplacer les avions de chasse traditionnels.

 

Cette stratégie de développement fait suite au rôle grandissant qu'ont tenu les drones lors des conflits armés ces dix dernières années et à l'appui indispensable qu'ils fournissent désormais aux forces armées américaines. Et s'ils restent pour le moment très limités dans leurs capacités par rapport aux chasseurs ou aux bombardiers classiques, cela pourrait bientôt (à l'échelle des projets aéronautiques) ne plus être le cas.

An RQ-4 Global Hawk taxies on the flightline as a U-2 makes its final approach

An RQ-4 Global Hawk taxies on the flightline as a U-2 makes its final approach

 

June 25, 2014: Strategy Page

 

The U.S. Air Force has changed its mind about the RQ-4 Global Hawk UAV. The motivation here is the need to cut costs in the face of a shrinking air force budget. So now the air force is asking Congress for two billion dollars to upgrade some RQ-4s so they can fully replace the versatile, elderly and expensive-to-operate U-2 reconnaissance aircraft. The air force is saving a lot of money by retiring entire types of aircraft (like U-2s and A-10s). The A-10s will be completely replaced by F-16s and smart bombs.

 

For years the air force was dissatisfied with the performance and operating costs of the RQ-4, pointing out that the U-2 was cheaper and, because of better sensors, more useful. But the RQ-4 manufacturer brought down the costs and increased reliability. Despite that criticism from the U.S. Air Force, American aircraft manufacturer Northrop Grumman continued to find customers for its RQ-4. In large part that’s because the RQ-4 has been much improved since 2010. The RQ-4 has become more reliable, efficient and flexible. Several of the new customers (like South Korea and Japan) want to use it for maritime reconnaissance, something the U.S. Navy is already doing. The cost of operating the RQ-4 has also been greatly reduced over three years, from $40,600 an hour to $18,900. That happened largely because there were more RQ-4s in service and each was flying more hours. That spread overhead costs over more flight hours. There was also a sharp reduction (by $14,000 an hour) in contractor support costs, largely brought on by improved aircraft reliability. Another factor driving this decline in costs was the air force threat to get rid of many RQ-4s because it was cheaper, per flight hour, to use the much older manned U-2s. Now that is no longer the case and the air force has backed away from dropping its RQ-4s and instead wants to retire the U-2s instead.

 

Back in 2011 the U.S. Air Force very publically gave up on the RQ-4. This came in the form of an air force announcement that they had stopped buying the RQ-4. Not only that but ten of the thirty-one Block 30 models ordered were cancelled. None of the planned Block 40 aircraft were to be built. Global Hawk remained in production because there were other users who were not as displeased as the air force. The U.S. Navy is buying 68 MQ-4C “Triton” BAMS (Broad Area Maritime Surveillance) models plus the two prototypes. Triton is to enter service by 2017.

 

While the RQ-4 has always been hailed as a revolutionary and successful system, most of the recon and surveillance jobs in the last decade were handled by the more reliable, cheaper, and numerous Predator and Reaper UAVs. Meanwhile, the air force was having more and more problems with the RQ-4, and that led to the public denunciation of the RQ-4 and Northrop Grumman. But as the war on terror dies down and the potential opponents include countries with air defenses, the higher flying RQ-4 becomes more valuable.

 

The 2011 decision was the result of the air force and the manufacturer feuding over design, cost, and quality control issues. The last straw was the unreliability of the new Block 30 models. This renewed Department of Defense threats to cancel the program. But manufacturer Northrop Grumman lobbyists have made sure the key members of Congress knew where Global Hawk components were being built and how many jobs that added up to. While that delayed the RQ-4 Block 30 cancellation it did not stop it. The air force was placated for a while when Northrop Grumman fixed some of the problems (some of which the manufacturer said don't exist or didn't matter). The Block 30 was supposed to be good to go, but the air force was not convinced and decided that Block 30 was just more broken promises. Congress was also tired of all the feuding and being caught between Northrup lobbyists and exasperated air force generals. Then there was political decision to cut the defense budget over the next decade. Something had to go.

 

You'd think the RQ-4 would be somewhat perfected by 2011. It was closer to that than many believed and is now considered a lot more reliable. Development of the RQ-4 began in the 1990s, as a DARPA research project. By 2006, per-aircraft costs were twenty-five percent over the original price. By 2007, production schedules had slipped as well. The air force and Northrop Grumman disagreed over what caused these problems. The air force blamed it on poor management. Northrop Grumman said it's all about dealing with complex technology. The air force pointed out that the RQ-4 was not high tech. The sensors often are but they are added to the aircraft after they came off the production line. Northrop Grumman continued to stonewall the air force and showed no signs of making any basic changes. Some air force procurement officials believed Northrop Grumman diverted resources to foreign customers, while taking advantage of the fact that there was no other supplier the air force could go to for long range UAVs. There was a lot of bad blood between the user and the manufacturer, which is not a good thing.

 

There were sixteen of the RQ-4A ("Block 10") aircraft built, fourteen for the U.S. Air Force, and two for the U.S. Navy. The later models were the larger RQ-4B (block 20, 30, and 40). Production has been consistently behind what Northrop Grumman had earlier promised. The air force originally planned to buy over forty Block 30s and wanted to get them faster, and with the reliability problems fixed. That did not work out before the war on terror largely ended and with it the big defense budgets.

 

In 2011, the air force transferred its remaining seven early model (Block 10) RQ-4s to other government agencies. These UAVs began flying nearly a decade ago and each has spent, on average, some three-thousand hours in the air. Some have spent over seven-thousand hours in the air, while others have mostly stayed on the ground. On average, these Block 10 aircraft flew once a week. But some ninety percent of hours flown were in combat operations. Subsequent models (Block 20, 30, and 40) had greater carrying capacity and reliability. Many payloads (various sensors) are designed for the larger models. But the Block 10 is still useful for civilian missions (disaster monitoring, border patrol, and all sorts of research).

 

Things had started off on a more promising note. The RQ-4 was still in development on September 11, 2001, but was rushed into action. The first production RQ-4A was not delivered until August, 2003. Although the RQ-4 could stay in the air for up to forty-two hours, all of them had only amassed about four-thousand flight hours by 2004. But most of those four-thousand hours, which were originally planned to involve testing of a new aircraft, were instead used to perform combat missions. Global Hawk also got to fly under difficult conditions, something an aircraft still being developed would not do.

 

In 2008, an RQ-4A Global Hawk made the first non-stop crossing of the Pacific, flying twelve-thousand kilometers from California to Australia in twenty-three hours. The Global Hawk has previously crossed the Pacific in several hops but it always had the endurance to do it non-stop. In the last decade RQ-4s have flown over fifty-five-thousand hours, most of that combat missions, and many of them from Persian Gulf bases. The latest models can fly twenty hour missions, land for refueling and maintenance, and be off in four hours for another twenty hours in the sky. But the reliability issues with the Block 30 made the longer missions infrequent. Otherwise, the RQ-4 has been very reliable, with aircraft being ready for action ninety-five percent of the time. An RQ-4 can survey about four-thousand square kilometers an hour.

 

The U.S. Air Force pays over $150 million for a fully equipped RQ-4, but only about 35 percent of that is for the UAV itself. Include payload (sensors and communications) and development costs and it nearly triples. The B version is about ten percent larger (wingspan of 42.3 meters/131 feet, and 15.5 meters/48 feet long) than the A model and can carry an additional two tons of equipment. To support that, there's a new generator that produces 150 percent more electrical power. The B version is a lot more reliable. Early A models tended to fail and crash at the rate of once every thousand flight hours, mostly because of design flaws. It was those flaws and delays in fixing them that got the air force so angry. The first three RQ-4Bs entered service in 2006, with some of those flaws still present, and it took over five years to clear that up.

 

At thirteen tons the Global Hawk is the size of a commuter airliner (like the Embraer ERJ 145) but costs more than twice as much. Global Hawk can be equipped with much more powerful, and expensive, sensors than other UAVs. These sensors comprise most of the cost of the aircraft. The spy satellite quality sensors (especially AESA radar) are usually worth the expense because they enable the UAV, flying at over 20,000 meters (60,000 feet), to get a sharp picture of all the territory it can see from that altitude.
