GAO Reports Persistent F-35 Software, Cost and Affordability Problems

Mar 25, 2014 defense-aerospace.com

(Source: Government Accountability Office; issued Mar 24, 2014)

 

F-35 Joint Strike Fighter: Problems Completing Software Testing May Hinder Delivery of Expected Warfighting Capabilities



Delays in developmental flight testing of the F-35's critical software may hinder delivery of the warfighting capabilities the military services expect.

F-35 developmental flight testing comprises two key areas: mission systems and flight sciences. Mission systems testing verifies that the software-intensive systems that provide critical warfighting capabilities function properly and meet requirements, while flight sciences testing verifies the aircraft's basic flying capabilities.

Challenges in development and testing of mission systems software continued through 2013, due largely to delays in software delivery, limited capability in the software when delivered, and the need to fix problems and retest multiple software versions.

The Director of Operational Test and Evaluation (DOT&E) predicts delivery of warfighting capabilities could be delayed by as much as 13 months. Delays of this magnitude will likely limit the warfighting capabilities that are delivered to support the military services' initial operational capabilities—the first of which is scheduled for July 2015—and at this time it is not clear what those specific capabilities will be because testing is still ongoing.

In addition, delays could increase the already significant concurrency between testing and aircraft procurement and result in additional cost growth.

Without a clear understanding of the specific capabilities that will initially be delivered, Congress and the military services may not be able to make fully informed resource allocation decisions.

Flight sciences testing has seen better progress, as the F-35 program has been able to accomplish nearly all of its planned test flights and test points. Testing of the aircraft's operational capabilities in a realistic threat environment is scheduled to begin in 2015. The program has continued to make progress in addressing some key technical risks.

To execute the program as planned, the Department of Defense (DOD) will have to increase funds steeply over the next 5 years and sustain an average of $12.6 billion per year through 2037; for several years, funding requirements will peak at around $15 billion.





Annual funding of this magnitude clearly poses long-term affordability risks given the current fiscal environment. The program has been directed to reduce unit costs to meet established affordability targets before full-rate production begins in 2019, but meeting those targets will be challenging as significant cost reductions are needed.

Additionally, the most recent cost estimate for operating and supporting the F-35 fleet is more than $1 trillion, which DOD officials have deemed unaffordable. This estimate reflects assumptions about key cost drivers the program can control, like aircraft reliability, and those it cannot control, including fuel costs, labor costs, and inflation rates.

Reliability is lower than expected for two variants, and DOT&E reports that the F-35 program has limited additional opportunities to improve reliability.

Aircraft manufacturing continued to improve in 2013, and management of the supply chain is evolving. As the number of aircraft in production has increased, critical learning has taken place and manufacturing efficiency has improved. For example, the prime contractor has seen reductions in overall labor hours needed to manufacture the aircraft, as expected. In 2013, the contractor delivered 35 aircraft to the government, 5 more than it delivered in 2012 and 26 more than it delivered in 2011. The prime contractor has put in place a supplier management system to oversee key supplier performance.

Why GAO Did This Study:

The F-35 Lightning II, also known as the Joint Strike Fighter, is DOD’s most costly and ambitious acquisition program. The program seeks to develop and field three aircraft variants for the Air Force, Navy, and Marine Corps and eight international partners. The F-35 is integral to U.S. and international plans to replace existing fighter aircraft and support future combat operations. Total U.S. planned investment in the F-35 program is approaching $400 billion to develop and acquire 2,457 aircraft through 2037, plus hundreds of billions of dollars in long-term spending to operate and maintain the aircraft.

The National Defense Authorization Act for Fiscal Year 2010 mandated that GAO review the F-35 acquisition program annually for 6 years. In this, GAO's fifth annual report on the F-35, GAO assesses the program's (1) ongoing development and testing, (2) long-term affordability, and (3) manufacturing progress.

GAO reviewed and analyzed manufacturing data through December 2013, program test plans, and internal DOD analyses, and spoke with DOD, program, and contractor officials.
What GAO Recommends


Recommendation for Executive Action
Due to the uncertainty surrounding the delivery of F-35 software capabilities, the Secretary of Defense should conduct an assessment of the specific capabilities that realistically can be delivered and those that will not likely be delivered to each of the services by their established initial operational capability dates. The results of this assessment should be shared with Congress and the military services as soon as possible but no later than July 2015.
DoD concurs.

Unmanned Vehicle Demo Showcases Leap-Ahead Technology

 

 

25.03.2014 US Army - army-guide.com

 

Working closely with Lockheed Martin and a conglomeration of Army technology, acquisition and user community stakeholders, the U.S. Army Tank Automotive Research Development and Engineering Center successfully demonstrated an unmanned military convoy Jan. 14 at Fort Hood, Texas.

 

From a rooftop in the Fort Hood training area, military and industry VIPs saw firsthand how the Autonomous Mobility Appliqué System, or AMAS, enabled two driverless Palletized Loading System prime movers and an M915 tractor trailer truck to seamlessly interact with a manned Humvee gun truck escort. The convoy negotiated oncoming traffic, followed rules of the road, recognized and avoided pedestrians and various obstacles, and then used intelligence and decision-making abilities to re-route their direction through a maze of test areas to complete both complex urban and rural line haul missions.

 

As the ground systems expert within the U.S. Army Research, Development and Engineering Command, TARDEC develops, integrates and sustains the right technology solutions to address ever-changing threats and shifts in strategic, technological and fiscal environments. Flexibility and adaptability are vital to future systems, and AMAS is designed to provide a wide range of military vehicle platforms with optionally-manned capabilities that will increase safety and provide the warfighter with additional flexibility.

 

"We're not looking to replace Soldiers with robots. It's about augmenting and increasing capability," said Col. Chris Cross, chief of Science and Technology at the Army Capabilities Integration Center.

 

Equipped with GPS, Light Detecting and Ranging systems, known as LIDAR, Automotive radar, a host of sensors and other high-tech hardware and software components, the common appliqué kit's intelligence and autonomous decision-making abilities can be installed in practically any military vehicle, transforming an ordinary vehicle into an optionally manned version.

 

AMAS can also keep personnel out of harm's way and provide Soldiers on manned missions with increased situational awareness and other safety benefits. For instance, AMAS also features collision mitigation braking, lane-keeping assist and a roll-over warning system, electronic stability control and adaptive cruise control. During manned missions, these additional safety features could theoretically increase Soldier performance. The robotic mode frees up the vehicle crew to more closely watch for enemy threats, while still leaving them the option of manually taking control of the vehicle when necessary.

 

"The AMAS hardware and software performed exactly as designed and dealt successfully with all of the real-world obstacles that a real-world convoy would encounter," said AMAS Program Manager David Simon, with Lockheed Martin Missiles and Fire Control.

 

AMAS development aligns with Army goals for the Future Force. At an Association of the United States Army breakfast in Arlington, Va., Jan. 23, Army Chief of Staff Gen. Raymond Odierno talked about the Army Modernization Strategy and the difficult decisions ahead.

 

"What is that leap-ahead technology that we need that could make a real difference for our Soldiers on the ground?" Odierno asked. "What is the technology that allows us to decrease the weight so we can be more expeditionary? I need tactical mobility for the future. We need to move towards mobility and try to determine how we sustain survivability while increasing mobility."

 

In his just-released CSA Strategic Priorities, Odierno added that we must prioritize Soldier-centered modernization and procurement of proven technologies so that Soldiers have the best weapons, equipment and protection to accomplish the mission.

 

Another AMAS demonstration with more vehicles and more complex notional scenarios is scheduled for later this year.

 

"We are very happy with the results, but the AMAS must undergo more testing before it becomes deployable," said TARDEC AMAS Lead Engineer Bernard Theisen.

 

"The vehicles and systems are replaceable, but nothing can replace the life of a Soldier. These systems keep Soldiers safe and make them more efficient," he said.

 

TARDEC is the ground systems expert within RDECOM. It provides engineering and scientific expertise for Department of Defense manned and autonomy-enabled ground systems and ground support systems; serves as the nation's laboratory for advanced military automotive technology; and provides leadership for the Army's advanced Science and Technology research, demonstration, development and full life cycle engineering efforts.

 

ABOUT TARDEC

 

TARDEC is part of the U.S. Army Research, Development and Engineering Command, which has the mission to develop technology and engineering solutions for America's Soldiers.

 

TARDEC is also a TACOM Life Cycle Management Command partner. In this capacity, it is responsible for critical technology functions within the "acquisition -- logistics -- technology" system life-cycle model, including: technology maturation and integration; technology subject-matter expertise; systems-level engineering analysis; and systems engineering.

 

TARDEC provides engineering support for more than 2,800 Army systems and many of the Army's and DoD's top joint development programs. The organization is responsible for maximizing the research, development, transition and sustainment of technologies and integration across ground systems.

 

RDECOM is a major subordinate command of the U.S. Army Materiel Command. AMC is the Army's premier provider of materiel readiness -- technology, acquisition support, materiel development, logistics power projection, and sustainment -- to the total force, across the spectrum of joint military operations. If a Soldier shoots it, drives it, flies it, wears it, eats it or communicates with it, AMC delivers it.

The Canadian Department of National Defense, which has ordered the upgrading of additional surveillance aircraft, has ordered new radar for the planes.

 

The Canadian Department of National Defense has contracted MacDonald, Dettwiler and Associates Ltd. to provide radar surveillance systems.

The eight systems to be provided under the $57 million contract will be for integration aboard CP-140 Aurora fleet, which Canada is upgrading.

MDA's said its surveillance system for theCP-140 provides high-resolution imaging capability to detect, locate, and classify, land and marine-based objects.

"Canada's DND and MDA have developed a successful working relationship based on quality, reliability and value,” said Don Osborne, an MDA vice president. “We are pleased to support DND with this repeat business and provide additional high-performance airborne radar surveillance systems.

"This contract underscores the global need for critical multi-mission intelligence, surveillance and reconnaissance capabilities that aid in the detection of illegal or hostile activity in maritime approaches or remote regions."

The CP-140 Aurora is Canada's intelligence, surveillance and reconnaissance Aircraft. The Lockheed Martin aircraft is based on the P-3 Orion airframe. Canada currently operates a fleet of 14 updated Auroras but announced last week it is investing in four more modernized CP-140s.

Modernization will be conducted under existing competitively awarded industry contracts and will include new avionics and missions systems.

24 March 2014 - naval-technology.com

 

The Bundeswehr, Rheinmetall and the Israel Aerospace Industries' (IAI) ELTA Group have successfully completed testing of the Multi Ammunition Softkill System (MASS) naval countermeasure system and NavGuard ship protection system.

 

During the trials, which were conducted under the guidance of the German Navy in Howachter Bay in the Baltic, MILAN antitank missiles were fired by the 2 Company, the German Army's 92 Mechanised Infantry Battalion, at the German Navy's mine warfare ship, HL 352 Auerbach, in Hohwachter Bay.

 

The warship was equipped with Rheinmetall's MASS system, specifically the MASS_ISS Integrated Sensor Suite version featuring various sensors for detecting radar, laser and electro-optical threats.

 

The NavGuard aboard the ship successfully detected the passive MILAN guided missile upon its launch and countermeasures were initiated by MASS to destroy the incoming missile.

 

The trials, based on an asymmetric warfare scenario, were intended to protect naval units from the threat posed by land-based forces armed with passive guided missiles.

 

Rheinmetall's MASS_ISS with integrated NavGuard is expected to be ready for full-scale production by 2015.

 

Designed to cope with new maritime and land-based threats to increase ship survivability, the ELM-2222S NavGuard lightweight, modular, self-protection system features a digital phased-array radar-based missile approach warning system (MAWS) to automatically detect, classify and verify threats, and consequently triggers the ships self-defence systems.

Many countries have a long tradition of purchasing Russian products. We are interested in promoting not only military helicopters but also Russian Helicopters’ commercial offering – in recent years we have achieved significant success on this front.”

Latin America is a high-growth market where Russian Helicopters has for many years sold a wide range of commercial and military helicopters. The new Mi-171A2 has been developed based on the world-famous Mi-8/17 series and drawing on its extensive operational history in various regions and climates. The helicopter makes use of the latest technologies and solutions, and also factors in feedback from potential clients and operators of Mi-8/17 series helicopters. The Mi-171A2 will be fitted with the latest power plant, a new rotor system and modern “glass cockpit” avionics suite.

The coaxial Ka-32A11BC is already well known to helicopter operators in the region. The helicopter received EASA certification in 2009, and meets FAR29 and AP-29 standards. The Ka-32A11BC can fly a range of missions and is a particularly valuable tool for fire-fighting, with more than 40 different options for fire-fighting equipment. In early 2013 the helicopter was chosen as the symbol of the Global Helicopter Firefighting Initiative (GHFI), and later that year in summer was actively deployed in Borneo to combat some of the worst wildfires in Indonesia’s history.

Russian Helicopters will also hold meetings with operators regarding the status of the Ka-62 programme and opportunities for deployment of the new helicopter, which has been created with extensive international collaboration. The helicopter is fitted with modern Ardiden 3G engines by Turbomeca, which meat the highest environmental and fuel-efficiency standards.

In its more than 35-year history, FIDAE has developed a reputation as the most important aerospace and defence exhibition in South America. Every year it brings together leading companies from commercial aviation, the defence sector and aircraft service industries, aerospace developers and the space industry.

Northrop Grumman Highlights Global Defence and Security Capabilities at DIMDEX 2014

 

DOHA, QATAR – March 25, 2014 Northrop Grumman Corporation

 

Northrop Grumman Corporation (NYSE:NOC) will highlight a range of its global defence and security solutions, including airborne early warning and control systems, aerial surveillance and mine countermeasures at DIMDEX 2014.

 

The Doha International Maritime Defence Exhibition & Conference (DIMDEX) takes place at the Qatar National Convention Centre, from March 25-27, 2014.

 

Northrop Grumman has had a presence in the Middle East for more than a decade. The recent appointments of Walid Abukhaled and Doug Raaberg as chief executives in the Kingdom of Saudi Arabia and United Arab Emirates respectively, enhances the company's presence and further positions Northrop Grumman for success in the Middle East region as the company continues to broaden its global market focus.

 

"Northrop Grumman's strong relationship with the Gulf Cooperation Council countries goes back many decades and is built on a legacy of trust and performance," said Abukhaled. "Our objective is to continue to work closely with our customers to build on this partnership and to provide the most advanced long-term capabilities to help meet the needs for enhanced defence and national security across the region."

 

The world-leading airborne early warning capabilities of its E-2D Advanced Hawkeye will be highlighted in Northrop Grumman's exhibit demonstrating the E-2D's capabilities for military and civil applications.

 

The E-2D Advanced Hawkeye couples a newly designed electronically scanned radar with a matching suite of sensors, avionics, processors, software and displays to provide the most technologically advanced command and control capability available worldwide. The new AN/APY-9 radar is the backbone of the E-2D Advanced Hawkeye and provides greater flexibility and significantly improved detection and tracking over all terrains. Northrop Grumman has delivered 12 E-2D Advanced Hawkeye aircraft to the U.S. Navy and initial operational capability with the Navy fleet is on track for 2015. The programme entered full-rate production in early 2013 after being declared operationally suitable and effective following a robust 10 month initial operational test and evaluation by the Navy.

 

Northrop Grumman's capability in mine detection will also be highlighted at the show. The AQS-24A high-speed mine-hunting system can be towed from the MH-53E and MCH-101 helicopters, and unmanned surface vessels. The AQS-24A and its predecessor systems, AQS-24 and the AQS-14, are the operational airborne mine-hunting search systems used by the U.S. Navy for the past 29 years. The helicopter-carried Airborne Laser Mine Detection System is a laser-based, light detection and ranging sensor system that detects, classifies and localizes surface and near-surface mine-like objects from above the waterline and is complementary to the AQS-24A.

 

Additionally on display will be a model of the Bat™ UAS, Northrop Grumman's family of multimission, persistent and affordable unmanned air vehicles that can be configured for tactical missions such as counter IED, communications relay, signals intelligence, electronic warfare (EW), and maritime surveillance. Combat-proven, Bat has been deployed to multiple forward operating bases in support of Operation Enduring Freedom. Bat has flown a large variety of payloads such as EO/IR, SAR, SIGINT, EW and Comms Relay.

The US Navy has taken delivery of the third Spearhead-class joint high-speed vessel (JHSV), USNS Millinocket (JHSV 3), from Austal USA in Mobile, Alabama, US, marking a major milestone in the ship's transition to operational status.

 

The 103m-long high-speed catamaran has been designed as part of the US Department of Defense's (DoD) ten-ship contract, worth more than $1.6bn, to support theatre cooperating missions, US Marine Corps, Seabees and Army transportation.

 

Strategic and Theater Sealift programme manager Captain Henry Stevens said: "Millinocket's speed, agility and cargo capabilities will be an asset to operations around the world."

 

Capable of transporting 600t of military cargo 1,200nm at an average speed of 35k, the JHSV can support a wide range of operations including non-combatant evacuation operations, humanitarian assistance and disaster relief.

 

Military Sealift Command (MSC) commander Rear Admiral Shannon said: "The JHSV ship class, including USNS Millinocket, will play an important part in the future of our joint forces in terms of affordability, flexibility, speed and agility."

 

The 2,400t versatile, non-combatant, transport ship can accommodate a crew of 42 and can cruise at a maximum speed of 43k using four MTU 20V8000 M71L diesel engines driving four Wartsila WLD 1400 SR waterjets through four ZF 60000NR2H reduction gears.

 

Equipped with Navair level 1 class 2 certified flight deck to support the CH-53E Super Stallion helicopter operations, the vessels can be used for military logistics and humanitarian relief operations, in addition to transportation of troops, military vehicles, cargo and equipment.

 

Owned and operated by MSC, USNS Millinocket will be manned by a crew of 22 civil service mariners.

USAF seeks new helmet-mounted display


21 Mar 2014 By Jon Hemmerdinger - FG
 

Washington DC - The US Air Force is seeking an improved digital helmet-mounted display (DHMD) for pilots, in response to the increasing complexity of aircraft and weapons systems.

In a recent request for information posted on the US government’s procurement website, the USAF says it seeks a helmet that improves pilots’ situational awareness and has features that integrate sensor data to help pilots better identify targets. The helmet system should also monitor pilot health and oxygen and carbon dioxide levels in the helmet.

Oxygen-related issues were found to have caused a series of hypoxia incidents that led to a four-month fleet-wide grounding of Lockheed Martin F-22 Raptors in 2011. An F-22 oxygen system problem also preceded one fatal crash.

However, the USAF's request – posted in February but updated on 13 March – does not say which aircraft the helmet would be used for, and the service did not immediately respond to a request for more information.

“The government is interested in receiving information on a broad array of technologies that have the potential to enhance aircrew warfighter operational capabilities in fixed-wing and rotary-wing aircraft platforms,” says the request.

“As weapon systems have become increasingly complex and aircrews are exposed to extensive amounts of battlespace information, it has become clear that a significant effort is necessary to provide a revolutionary leap in [DHMD] capability.”

The request says the USAF seeks a new helmet that makes better use of symbol displays – called symbology – and possibly uses “conformal”, or three-dimensional, symbols.

Also of interest is eye tracking technology that would allow information to be presented where pilots are looking, rather than where they are facing, says the USAF.

The service also wants a helmet that digitally incorporates night vision capability, and one that collects information gained from a variety of sensors, including mid-wave and long-wave infrared sensors and light detection and ranging (LIDAR) sensors, says the request.

The USAF wants that information to be processed using algorithms that would help the pilot to better detect and identify ground objects, such as vehicles, humans, terrain hidden by fog, haze or dust, as well as objects concealed by floors and vehicles, says the service.

In addition, the system should be able to distinguish whether humans or vehicles are friend or foe, says the notice.

It would also have cognitive and physiological pilot monitoring that would identify, and prevent mishaps caused by pilot fatigue, cognitive overload, unconsciousness or spatial disorientation. The eye tracking system could potentially monitor vigilance and sleepiness by monitoring blinking and the amount of time a pilot’s eyes are closed, says the request.

The USAF is interested in monitoring heart activity with electrocardiogram data and brain activity with electroencephalography data.

The helmet system could also monitor “galvanic skin response” – used to identify sweat – blood flow, hydration and mask oxygen and carbon dioxide content, says the USAF.

In 2011, the service grounded all F-22s due to hypoxia incidents later attributed to issues with the aircraft’s onboard oxygen generation system and the pilot’s upper pressure garment. The grounding followed an F-22 crash in November 2010 that was preceded by failure of an oxygen sensor. That crash killed the pilot.

The USAF blamed the crash on the pilot, saying he failed to activate an emergency oxygen supply, but a later Pentagon report found the service’s conclusions were based on insufficient evidence.

Lockheed, which is integrating a helmet-mounted display from Vision Systems International (VSI) into its F-35 Joint Strike Fighter, says it does not know which aircraft the new helmet is intended for.

Rockwell Collins, which joined with Elbit Systems to form VSI, could not be reached for comment.

The helmet for the F-35, the only fighter that currently has a digital helmet-mounted display, suffered developmental delays sufficient to lead the military to seek an alternative helmet in September 2011.

BAE Systems proposed a design, but the F-35’s programme office decided in October 2013 to stick with VSI.

Lockheed says the latest “third-generation” VSI helmet is progressing, noting that it plans to flight test the helmet in an F-35 in the third quarter of this year.

Features of VSI’s helmet include symbology, a virtual head-up display, mounted night vision and real-time video that is integrated with the aircraft’s 360˚ situational awareness system, says Lockheed

Harris’s Falcon III radio completes interoperability testing with MUOS

 

 

21 March 2014 naval-technology.com

 

Harris's Falcon III AN/PRC-117G multiband manpack radio, hosting the Mobile User Objective System (MUOS) waveform, has successfully completed initial interoperability testing.

 

The test, conducted at the Joint Tactical Networking Center MUOS Reference Implementation Laboratory in San Diego, California, US, demonstrated interoperability with the addition of MUOS software to AN/PRC-117G radios, without modification from their standard hardware configurations.

 

The US Navy's MUOS is a next-generation narrowband tactical satellite communications system capable of enhancing ground communications for US forces on the move.

 

In addition to providing cellular-based service through tactical radios, the MUOS offers more communications capability for military users over existing systems, including simultaneous voice, video and data - similar to the capabilities experienced today with smart phones.

"Simple software upgrades will bring MUOS to more than 30,000 AN/PRC-117G radios already in use, giving the DoD the most cost-effective solution for rapidly transitioning its tactical satellite radio inventory to support this important new capability."

 

Harris RF Communications Department of Defense business president George Helm said that the company is rapidly delivering on its commitment to provide the MUOS waveform in AN/PRC-117G tactical radios.

 

"Simple software upgrades will bring MUOS to more than 30,000 AN/PRC-117G radios already in use, giving the DoD the most cost-effective solution for rapidly transitioning its tactical satellite radio inventory to support this important new capability," Helm added.

 

In order to provide a new and more capable UHF military satellite communication system, the MUOS uses a commercial 3G Wideband Code Division Multiple Access (WCDMA) cellular technology with geosynchronous satellites.

 

A new round of tests of the AN/PRC-117G is scheduled to commence at the US government MUOS system integration labs in Arizona, US.

 

Last year, the radio successfully completed separate on-air tests in San Diego and near the North Pole.

21 March 2014 Airbus Helicopters

 

For the first time in Latin America under its new branding, Airbus Helicopters will display its efficient and adapted product line-up at next week’s FIDAE International Air and Space Fair, featuring rotorcraft flown by a cross-section of Latin American operators to underscore the company’s leadership in this portion of the world.

 

Maintaining an overall 40 percent market share in Latin America during the past five years with a deployed fleet of more than 1,350 rotorcraft across the region, Airbus Helicopters has developed a diversified customer base, as well as a strong industrial presence – with 1,200 employees assigned to its subsidiaries in Brazil, Chile and Mexico for production, maintenance and support.

 

Airbus Helicopters’ 12 different rotorcraft types position the company as the only manufacturer covering Latin America’s full operational requirements, from lightweight to heavy-lift; with designed-in performance for duties in the region’s unique conditions, from jungle and hot environments to high altitudes in the Andes.

 

The product line’s versatility and efficiency is underscored by Airbus Helicopters’ Ecureuil family: more than 600 are in service across the region, having logged over 130,000 flight hours in missions that include passenger transport, mining support, power line maintenance, fire-fighting and the transportation of external loads.

 

Exhibited at FIDAE will be a utility-configured single-engine AS350 B3 Ecureuil from a Chile based aerial services operator that specializes in mining and energy, construction, civil work, extreme sports, tourism and filming.

 

Other lightweight helicopters on display at FIDAE are the EC120 and the EC130 T2 – the latter being the first of this type to arrive in the South Cone. Retaining the EC130 helicopter’s external lines, this latest Ecureuil family member benefits from Airbus Helicopters’ continued investment in its products – with approximately 70 percent of the EC130 T2’s airframe structure modified. New features include a more powerful Arriel 2D turboshaft engine and upgraded main gearbox; along with a cabin interior structure redesign and a cockpit update for enhanced man-machine interface.

 

The EC145, also showcased at FIDAE, is one of the most popular light twin-engine helicopter models, and is relied on around the globe for public security and disaster relief missions. With more than 500 delivered to date, this helicopter serves in the police fleets of 26 countries worldwide. Powerful, versatile and perfectly suited to the region’s terrain, the EC145 has become a reference for public services missions in Latin America, where it is being operated by the public services of Argentina, Brazil, Mexico – and more recently Bolivia and Peru, with recent purchases for four and five aircraft, respectively.

 

The Dauphin family’s EC155 B1 arrives in the region to set new standards for private aviation in terms of style and comfort. Presenting the biggest cabin in its class, the EC155 B1 offers a unique combination of elegance, comfort, silence and speed and, it is well position for the growing trend among private operators for large-cabin helicopters. High-end options include soft leather club seats, power sources for laptops, adjustable reading lights, cabin air conditioning, as well as satellite communications and in-flight entertainment for an exclusive flight experience.

 

Completing Airbus Helicopters’ flight-line presence at FIDAE is the latest Cougar family member: the AS532 ALe version of the workhorse Super Puma family that incorporates the EC225 version’s glass cockpit and four-axis autopilot. Of the 870 Super Puma/Cougar helicopters delivered to date, more than 100 are in service in Latin America, with 60 others on order. Most of the continent’s armed forces are operating this family for a wide variety of missions that range from assault and combat to special operations, tactical transport, SAR, medical evacuation and the transport of high-ranking officials.

 

The Cougar family is present in Argentina, Bolivia, Ecuador, Brazil, Chile, Mexico and Venezuela – with Airbus Helicopters’ Helibras subsidiary in Brazil producing the EC725 version for the Brazilian Armed Forces.

 

Airbus Helicopters’ participation in this year’s FIDAE is the company’s first at the biennial show in its new branding, underscoring its commitment toward customer satisfaction, quality, safety and competitiveness.

La course à l'armement technologique passe par les vols hypersoniques

 

24/03/2014 Par Julien Bergounhoux - industrie-techno.com

 

 

L'éternelle course à l'armement technologique au niveau mondial est en train de prendre un nouveau tournant. Alors que les drones occupent le devant de la scène depuis plusieurs années, le facteur de la vitesse est de nouveau d'actualité. En atteignant des vitesses hypersoniques, supérieures à Mach 5, une armée pourrait frapper ses adversaires avant qu'ils n'aient le temps de réagir.

A l'heure où les systèmes de défense aérienne deviennent de plus en plus sophistiqués et performants, le Pentagone considère le vol hypersonique (c'est-à-dire supérieur à Mach 5, qui correspond à 6150 km/h) comme un élément essentiel du maintien de sa supériorité aérienne.

En effet, alors que la plupart des missiles de croisière actuels sont subsoniques, ce type de technologie pourrait s'avérer révolutionnaire s'il parvenait à être déployé dans un cadre opérationnel. Il permettrait de contrecarrer n'importe quel système de défense en volant simplement à une vitesse trop importante pour que celui-ci puisse intercepter la menace. Cela n'est pas sans rappeler le SR-71 "Blackbird" de Lockheed, avion de reconnaissance furtif américain mis en service en 1966 et dont la vitesse en vol de Mach 3, inégalée à l'époque, le rendait capable d'échapper aux missiles anti-aériens en accélérant.

 

CONCURRENCE INTERNATIONALE

Les systèmes de défense russe, chinois et syrien sont notamment identifiés comme étant très avancés, a révélé Al Shaffer, secrétaire adjoint de la Défense pour la recherche et l'ingénierie, dans des propos rapportés par DefenseTech. Les Etats-Unis voudraient donc se prémunir en cas d'affrontement avec ces puissances étrangères, qui font elles-mêmes beaucoup de progrès non seulement en matière de guerre électronique (la pierre angulaire de l'attaque et de la défense aérienne moderne), mais également de vitesse.

Ainsi, la Chine a testé un planeur hypersonique, le WU-14, en début d'année. Lancé par un missile ballistique intercontinental (ICBM) jusqu'à 100 km d'altitude, ce prototype se détache ensuite et manœuvre jusqu'à sa cible à des vitesses qui atteindraient Mach 10. Un essai que la Chine s'est empressée de déclarer comme ne visant personne, mais qui a été ressenti par certains Outre-Atlantique comme une démonstration de force. 

L'avancée technologique des Etats-Unis en est-elle menacée? Bien que la défense aérienne des Etats-Unis soit prévue pour intercepter des cibles hypersoniques (missiles intercontinentaux), elle ne peut les détecter et traquer correctement que lorsque leur trajectoire passe par l'espace, ce qui n'est pas le cas ici, rendant une interception beaucoup plus délicate. D'autant que la Russie prépare également de son côté des armes à propulsion hypersonique, et serait beaucoup plus avancée que la Chine dans leur développement.

 

PROPULSION PAR SUPERSTATORÉACTEUR

Pourtant, le département de la Défense américain n'est pas en reste. Il travaille à la conception d'un appareil hypersonique depuis 2004 au travers d'un programme qui réunit l'US Air Force, la Darpa, la Nasa, Boeing, et Pratt & Whitney Rocketdyne. Ce programme a donné lieu à 4 vols du démonstrateur X-51A (dit "Waverider" car il chevauche sa propre onde de choc) entre 2010 et 2013, et servira à l'élaboration du projet HSSW (High Speed Strike Weapon), un missile volant à plus de Mach 5 dont la mise en service est prévue dans le courant des années 2020.

Pour atteindre ces vitesses, le X-51A a lors de son dernier vol d'abord été amené à environ 15 000 m d'altitude par un Boeing B-52H, avant d'accélérer jusqu'à Mach 4,8 en 26 secondes à l'aide d'un moteur-fusée. Après s'en être séparé, il a utilisé un superstatoréacteur (scramjet) Pratt & Whitney SJY61 pour atteindre Mach 5,1, montant à plus de 18 000 m d'altitude. Un procédé similaire à celui de son prédécesseur civil, le X-43 de la Nasa (voir ci-contre une visualisation de sa mécanique des fluides numérique lors d'un vol à Mach 7), qui avait en 2004 atteint une vitesse record de 10 461 km/h, soit Mach 9,6. Evidemment, en plus de ces démonstrateurs, un certain nombres de projets militaires américains (le X-41 CAV, le X-37B) restent encore secrets.

Les statoréacteurs (à combustion supersonique ou non) sont des réacteurs qui n'utilisent pas de pièces mobiles et dont la poussée est produite par l'éjection de gaz résultant de la combustion du carburant. Leur principal désavantage est qu'ils ne peuvent propulser un aéronef qu'une fois qu'il a atteint une certaine vitesse, mais le fait qu'ils nécessitent moins de pièces permet aussi de réduire leur coût de fabrication, un avantage non négligeable lorsqu'ils n'ont pas vocation à être réutilisés (par exemple dans le cas de missiles).

The Italian-built corvette Abu Dhabi entered service in late 2012. A United Arab Emirates company, Etihad Ship Building, expects this year to open negotiations with the UAE Navy 'for a more developed' Abu Dhabi-class vessel, a company official said.

 

Mar. 24, 2014 - By AWAD MUSTAFA – Defense News



 

DUBAI — Having honed their skills on homegrown contracts, United Arab Emirates shipyards are seeking sales from their Arabian Gulf neighbors.

Over the past five years, the UAE has become the gulf’s leading hub for naval shipbuilding, as well as the maintenance, repair and overhaul of warships. Two of the biggest reasons are Abu Dhabi Ship Building (ADSB) and Etihad Ship Building (ESB), said Matthew Hedges, military analyst for the Institute for Near East and Gulf Military Analysis (INEGMA), based here.

“The UAE naval industry is a leading player in the region, with ADSB and Etihad Shipbuilding contributing a large amount to indigenous capabilities,” he said. “Other [Gulf Cooperation Council] countries can’t match the UAE capabilities.”

Another growing company is Al Seer Marine, which is becoming known for its unmanned surface vehicles.

Now the companies are touting their wares to neighboring countries.

Potential regional customers for ADSB’s flagship Baynunah corvette include the Saudi Navy, which has embarked on a US $20 billion expansion program and is said to be considering the purchase of up to a dozen new warships.

ADSB also hopes for more sales to Kuwait. In February 2013, ADSB signed contracts to supply the Kuwaiti Navy with two 64-meter landing craft, one 42-meter landing craft and five 16-meter composite fast landing craft.

Established in 1996, ADSB initially focused on naval repairs and refits, then expanded to build sophisticated warships. Today, it handles the construction, repair and refit of naval, military and commercial vessels, and has an order book that tops $1 billion.

“Through partnerships with international players, the UAE has been able to construct some of the world’s most advanced ships, with the marquee product being the Baynunah-class corvette,” Hedges said.

The UAE launched the Baynunah class with a January 2004 order for a new class of multipurpose missile corvette. Two of six under contract have been delivered, the latest in February.

The 70-meter vessels were designed in collaboration with Constructions Mecaniques de Normandie (CMN) of Cherbourg, France, as a derivative of CMN’s BR70 70-meter corvette design.

The Baynunahs will mainly be used for patrol and surveillance, minelaying, interception and other anti-surface warfare operations in territorial waters and exclusive economic zones. The vessels are to be the world’s largest steel-hulled vessels that use waterjets for propulsion.

Built on a deep-V hard-chine hull, the corvette has a shallow draft and a stealthy superstructure, a helicopter landing deck and a hangar. It accommodates a crew of 55.

 

Etihad's Programs

Etihad Ship Building — established in 2010 as a joint venture between Italian shipbuilder Fincantieri, Al Fattan Shipyard and Melara Middle East — also is looking to build on a successful 2013.

“On different fronts, Fincantieri and Etihad Ship Building have started negotiations with different gulf countries, including Kuwait, Qatar, Saudi Arabia and Iraq,” said Achille Fulfaro, ESB’s general manager. “For Qatar, Kuwait and Saudi Arabia in 2014, the negotiations will start and we will go in to deep analysis of their requirements, and we hope to create the conditions for production.”

“We expect also to start negotiations [with the UAE Navy] on a new Abu Dhabi class, for a more developed new ship in that class,” he said.

Fulfaro said ESB will base its services and production at its facilities in Abu Dhabi.

“We consider Etihad Ship Building as the lead in the gulf region, so we are making the relevant investments to be ready to produce more vessels in 2014,” he said.

But Fulfaro said his company is open to discussing new joint ventures or other work-sharing conditions.

Last year, ESB delivered two Falaj-class stealth offshore patrol vessels and an Abu Dhabi-class stealth corvette to the UAE Navy. It also won a €100 million (US $138 million) contract for services, logistics and maintenance of combatant vessels in the UAE, Fulfaro said. Last year, the company signed a contract with the Iraqi Navy as well for the maintenance of four patrol vessels at ESB.

“We signed the services contract, and Fincantieri delivered the first Falaj-class and Abu Dhabi-class vessels within the right timeframe and budget,” he said. “The trials phase has been completed with the complete satisfaction of the client, and now we expect to close negotiations on further Falaj- and Abu Dhabi-class vessels” for the UAE Navy.

The negotiations on the Falaj program are expected to be completed quickly, he said.

Among ESB’s products is the Falaj-class patrol vessel. Based on the Italian Coast Guard’s Diciotti class, it can handle a variety of missions, including patrol, surveillance, and land and surface attacks. It is also equipped to fight off air and surface weapons.

Another is the Abu Dhabi-class corvette, based on the design of the Italian Navy’s four Commandante-class vessels. The Abu Dhabis are 88 meters long and displace 1,650 tons.

To be crewed by about 70, each vessel can reach 25 knots, or deliver a range of more than 3,000 nautical miles at 14 knots.

Weapons on the corvette include two 30mm Marlin weapons stations and a 76mm naval gun.

 

Unmanned Surface Vessels

Hedges, the INEGMA analyst, said Al Seer Marine has drawn international recognition for its three types of unmanned surface vessels (USVs).

Useful for ISR, border protection and port security, the first are expected to deploy in UAE ports this year, he said.

“There is a potential in the future to arm them to protect offshore rigs and illegal smuggling,” he said.

The three variants are called Sea Serpent, Oscar and Bravo.

Sea Serpent is a 3-meter, 320-kilogram vessel about the size of a large jet ski. It has a maximum speed of 50 knots and operates on one petrol engine. Used for security around VIP yachts, they also were designed for harbor surveillance and port security.

Bravo is a rigid inflatable boat based on the Finnish-built Boomeranger that can be operated either as a remote or a piloted boat.

Oscar, an 11-meter, 6,500-kilogram boat that runs on two 500-horsepower diesel engines with water jet propulsion, is used for security patrols and is equipped with computers, sensors and software to detect and process data.

“The boats are remote-controlled through a command-and-control station, which is on land or a mother ship at sea, and are fitted with some of the most advanced robotics and surveillance equipment,” Matthew Tracy, Al Seer Marine’s USV project manager, told local media.

“Three or four boats can be controlled and used by two operators at once instead of using between 12 and 16 crew,” Tracy said.

If fitted with satellite communications gear, he said, the boats can be controlled from anywhere in the world.
