JSF first flight delayed again By Caitlin Harrington JDW Staff ReporterWashington, DC The first flight of the F-35 Joint Strike Fighter (JSF), originally scheduled to take place in August, could be pushed back as late as December, Brigadier General Charles Davis, Program Executive Officer for the F-35 Program Office, has told Jane's. Gen Davis said the JSF will probably not be ready for first flight on 31 October - the most recent date to be cited by officials at prime contractor Lockheed Martin. The USD276 billion JSF programme is the most expensive acquisition in the US Department of Defense's (DoD) history. Gen Davis estimated that a one-year delay in production could add anywhere from USD4 million to USD6 million to the cost of each aircraft, depending on the variant and the timing in the production schedule. Another issue lurking in the background is the possibility that the US Air Force may consider alternative ways to boost its inventory of air superiority fighters while it is waiting for JSF to come on line. Christopher Bolkcom, a Congressional Research Service defence expert, warned that if the air force decides to focus time and energy on the production of an alternative aircraft - such as the F-22 Raptor or the F-15E+ Super Eagle - it would detract resources from JSF and possibly contribute to further delays.
Joint Strike Fighter Officially Named "Lightning II"FORT WORTH, Texas, July 7, 2006 -- The Lockheed Martin F-35 Joint Strike Fighter was officially named Lightning II, in a ceremony held today in Fort Worth, Texas. The name echoes those of two formidable fighters from the past: the World War II-era Lockheed P-38 Lightning and the mid-1950s Lightning supersonic jet, built by English Electric."The F-35 Lightning II will carry on the legacy of two of the greatest and most capable fighter aircraft of all time," said Ralph D. Heath, president of Lockheed Martin Aeronautics Co. "Just as the P-38 and the British Lightning were at the top of their class during their day, the F-35 will redefine multi-role fighter capability in the 21st century."Attendees at the event included U.S. Deputy Secretary of Defense Gordon England and U.S. Air Force Chief of Staff Gen. T. Michael Moseley, who announced the F-35's new name. Also in attendance were U.S. Senators Kay Bailey Hutchison and John Cornyn of Texas, U.S. Congresswoman Kay Granger of Fort Worth, and representatives from the eight nations that are partnering with the U.S. in the F-35's development: the United Kingdom, Italy, the Netherlands, Turkey, Canada, Australia, Denmark and Norway."The F-35 Lightning II will be the centerpiece of airpower in the 21st century for America and our allies," Secretary England said. "Congratulations to the talented team of aerospace workers both in the United States and from our many international partners on reaching this important milestone." Gen. Moseley added, "This aircraft represents the fruits of lessons learned over a hundred years of flight and aerial combat. We're excited about bringing it into our inventory, and warfighters around the globe are excited about flying it in defense of freedom." English Electric, maker of the Lightning jet, later became BAE Systems, a principal industrial partner on the JSF program. With its afterburners lit, the twin-engine jet could reach speeds of 1,500 miles per hour. Like the F-35, the Lightning in its day represented a profound leap ahead in capability compared to the aircraft it replaced. It remained in service until 1988, largely because of its exceptional performance.Likewise, the P-38 Lightning was built by Lockheed, now Lockheed Martin, the JSF program's prime contractor. During World War II, the P-38 scored the most aerial victories of any U.S. Army Air Forces fighter in the Pacific theater. Designed as a high-altitude interceptor, the sleek P-38 evolved into a versatile aircraft that was also used for dive bombing, level bombing, ground strafing and photo-reconnaissance missions.The F-35 carries on both the Lightning name and its tradition of excellence. The Lightning II is a 5TH Generation, supersonic stealth fighter designed to replace a wide range of existing aircraft, including AV-8B Harriers, A-10s, F-16s, F/A-18 Hornets and United Kingdom Harrier GR.7s and Sea Harriers. The F-35 will be the most powerful single-engine fighter ever made.Lockheed Martin is developing the F-35 with its principal industrial partners, Northrop Grumman and BAE Systems. Two separate, interchangeable F-35 engines are under development: the Pratt & Whitney F135 and the GE Rolls-Royce Fighter Engine Team F136.The inaugural flight of the first F-35, a preproduction conventional takeoff and landing variant, is planned for later this year. Fifteen F-35s will undergo flight test, seven will be used for static testing and another will validate the aircraft's radar signature.Fonte

Tá bem queres ser mais perfeccionista diz-se então que o melhor é so para consumo da US Armed Forces
...para mim o F-35 não para de um F-16 com cara lavada e que consegue aterrar e levantar na vertical (alguns pelo menos), é como os carros também existem os opel corsa velhinhos (os quadrados) e os mais recentes (redondos) mas são ambos opel corsa, para mim o F-35 é um F-16 "quitado" e cujo custo não compensa.
New combat helmet is a vision of the future9 Nov 07 The developmental pilot helmet for the highly advanced F-35 Joint Strike Fighter is currently being evaluated by defence scientists at Boscombe Down in Wiltshire. The developmental test helmet for the Joint Strike Fighter (JSF)In 2001 the Government selected the Joint Strike Fighter to meet the requirement for a stealthy multi-role fighter to operate from the future aircraft carriers, replacing the Harriers.Unlike modern fast jet aircraft the Joint Strike Fighter, which is planned to replace the famous Harrier, does not have a ‘traditional’ head-up display – instead the computerised symbology is displayed directly onto the pilot’s visors. This Helmet Mounted Display System provides the pilot with cues for flying, navigating and fighting the aircraft. It will even superimpose infra-red imagery onto the visor which allows the pilot to ‘look through’ the cockpit floor at night and see the world below.Royal Air Force Squadron Leader Rob Harrison, who was one of the pilots who took part in the subjective assessment tests, flying in a Hawk aircraft at Boscombe Down said: "It cannot be stressed how important this sort of evaluation is to the Joint Strike Fighter Programme. The helmet is a critical piece of equipment and simply has to work."The helmet programme is being evaluated by the MOD’s DE&S Joint Combat Aircraft Integrated Project Team along with the RAF’s Centre for Aviation Medicine. The developmental head gear is manufactured by Vision Systems International and Helmet Integrated Systems Limited. The highly advanced Joint Strike Fighter, which is being built by Lockheed Martin, is planned to replace the RAF and RN’s Harriers.A Memorandum of Understanding (MoU) on the next phase of the Joint Strike Fighter (JSF) programme was signed on 12 December 2006 by then Minister of State for Defence Procurement, Lord Drayson, following a meeting with US Deputy Secretary of Defence, Gordon England, in Washington DC.
