Program cost increases and further delays & Concerns over performance and safety of the F35.

Program cost increases and further delays On 21 April 2009, media reports, citing Pentagon sources, said that during 2007 and 2008, computer spies had managed to copy and siphon off several terabytes of data related to the F-35's design and electronics systems, potentially enabling the development of defense systems against the aircraft.[37] However, Lockheed Martin has rejected suggestions that the project has been compromised, saying that it "does not believe any classified information had been stolen".[38]




On 9 November 2009, Ashton Carter, under-secretary of defense for acquisition, technology and logistics, acknowledged that the Pentagon "joint estimate team" (JET) had found possible future cost and schedule overruns in the project and that he would be holding meetings to attempt to avoid these.[39] On 1 February 2010, Gates removed the JSF Program Manager, U.S. Marine Corps Major General David Heinz, and withheld $614 million in payments to Lockheed Martin because of program costs and delays.[40][41]



On 11 March 2010, a report from the Government Accountability Office to United States Senate Committee on Armed Services projected the overall unit cost of an F-35A to be $112M in today's money.[42] In 2010, Pentagon officials disclosed that the F-35 program has exceeded its original cost estimates by more than 50 percent.[43] An internal Pentagon report critical of the JSF project states that "affordability is no longer embraced as a core pillar". On 24 March, Gates termed the recent cost overruns and delays as "unacceptable" in a testimony before the U.S. Congress. He characterized previous cost and schedule estimates for the project as "overly rosy". However, Gates insisted the F-35 would become "the backbone of U.S. air combat for the next generation" and informed the Congress that he had expanded the development period by an additional 13 months and budgeted $3 billion more for the testing program while slowing down production.[44] Lockheed Martin expects to reduce government cost estimates by 20%.[45]



In November 2010 as part of a cost-cutting measure, the co-chairs of the National Commission on Fiscal Responsibility and Reform suggested canceling procurement of the F-35B and halving orders of F-35As and F-35Cs.[46][47][48] At the same time Air Force Magazine reported that "Pentagon officials" are considering canceling the F-35B because its short range means that the bases or ships it operates from will be within range of hostile tactical ballistic missiles.[49] However Lockheed Martin consultant Loren B. Thompson said that this rumor is merely a result of the usual tensions between the US Navy and Marine Corps, and there is no alternative to the F-35B as an AV-8B replacement.[50] He also confirmed that there would be further delays and cost increases in the development process because of technical problems with the aircraft and software, but blamed most of the delays and extra costs on redundant flight test.[51][52]



The Center for Defense Information estimated that the program would be restructured with an additional year of delay and $5 billion in additional costs.[53] On 5 November 2010, the Block 1 software flew for the first time on BF-4 which included information fusion and initial weapons-release capability.[54] As of the end of 2010, only 15% of the software remains to be written, but this includes the most difficult sections such as data fusion.[55] But in 2011 it was revealed that only 50% of the eight million lines of code had actually been written and that it would take another six years and 110 additional software engineers in order to complete the software for this new schedule.[56]



In January 2011 Defense Secretary Robert Gates expressed the Pentagon's frustration with the skyrocketing costs of the F-35 program when he said "The culture of endless money that has taken hold must be replaced by a culture of restraint." Focusing his attention on the troubled VTOL F-35B Gates ordered "a two-year probation", saying it "should be canceled" if corrections are unsuccessful.[57] However, Gates has stated his support for the program.[58] Some private analysts, such as Richard Aboulafia, of the Teal Group state that the whole F-35 program is becoming a money pit.[57]



Former Pentagon manager Paul Kaminski has said that the lack of a complete test plan has added five years to the JSF program.[59] As of February 2011, the main flaws with the aircraft are engine "screech", transonic wing roll-off and display flaws in the helmet mounted display.[60]



The current schedule has the delivery of basic combat capability aircraft in late 2015, followed by full capability block three software in late 2016.[61] The $56.4 billion development project for the aircraft should be completed in 2018 when the block five configuration is expected to be delivered, several years late and considerably over budget.[62]



In November 2010, the GAO found that "Managing an extensive, still-maturing global network of suppliers adds another layer of complexity to producing aircraft efficiently and on-time" and that "However, due to the extensive amount of testing still to be completed, the program could be required to make alterations to its production processes, changes to its supplier base, and costly retrofits to produced and fielded aircraft, if problems are discovered."[63] A year later, program head Vice Adm. David Venlet confirmed that the concurrency built into the program "was a miscalculation".[64]



Delays in the F-35 program may lead to a "fighter gap" where America and other countries will lack sufficient jet fighters to cover their requirements.[65] Israel may seek to buy second-hand F-15s to cover its gap,[66] while Australia may also seek to buy more American fighters from the USN to cover their own capability gap in the face of F-35 delays.[67]



Initial Operational Capability (IOC) will be determined by software development rather than by hardware production or pilot training.[68]



In May 2011, the Pentagon's top weapons buyer Ashton Carter said that its new $133 million unit price was not affordable.[69]



In 2011 The Economist warned that the F-35 was in danger of slipping into a "death spiral" where increasing per aircraft costs would lead to cuts in number of aircraft ordered which would lead to further cost increases and further order cuts.[70] Later that year four aircraft were cut from the fifth LRIP order to pay for cost overruns.[71]



This was followed by a contract dispute where the Pentagon insisted that Lockheed Martin help cover the costs of fixes to aircraft already produced.[72] Lockheed Martin also objected to cost sharing in the program because even at this late date the remaining development challenges posed an uninsurable unbounded risk that the company could not cover.[73] However the Senate Armed Services Committee strongly backed the Pentagon position.[74]



Also in 2011 a Congressional Joint Strike Fighter Caucus was formed by some of the top recipients of Lockheed Martin contributions.[75]



 Concerns over performance and safety In 2006 the F-35 was downgraded from "very low observable" to "low observable", a change former RAAF flight test engineer Peter Goon likened to increasing the radar cross section from a marble to a beach ball.[76]



Andrew Krepinevich has questioned the reliance on "short range" aircraft like the F-35 or F-22 to 'manage' China in a future conflict and has suggested reducing the number of F-35s ordered in favor of a longer range platform like the Next-Generation Bomber, but Michael Wynne, then United States Secretary of the Air Force rejected this plan of action in 2007.[77][78][79] However in 2011, the Center for Strategic and Budgetary Assessments (CSBA) pointed to the restructuring of the F-35 program and the return of the bomber project as a sign of their effectiveness, while Rebecca Grant said that the restructuring was a "vote of confidence" in the F-35 and "there is no other stealthy, survivable new fighter program out there".[80] Lockheed has also said that the F-35 is designed to launch internally carried bombs at supersonic speed and internal missiles at maximum supersonic speed.[81]



In 2008 it was reported that RAND Corporation conducted simulated war games in which Russian Sukhoi Su-35 fighters apparently defeated the F-35.[82] As a result of these media reports, then Australian defence minister Joel Fitzgibbon requested a formal briefing from the Australian Department of Defence on the simulation. This briefing stated that the reports of the simulation were inaccurate and did not actually compare the F-35's flight performance against other aircraft.[83]



The Pentagon and Lockheed Martin added that these simulations did not address air-to-air combat.[84][85] A Lockheed Martin press-release points to USAF simulations regarding the F-35's air-to-air performance against potential adversaries described as "4th generation" fighters, in which it claims the F-35 is "400 percent" more effective. Major General Charles R. Davis, USAF, the F-35 program executive officer, has stated that the "F-35 enjoys a significant Combat Loss Exchange Ratio advantage over the current and future air-to-air threats, to include Sukhois".[85] The nature of the simulations, and the terms upon which the "400 percent" figure have been derived remains unclear. Regarding the original plan to fit the F-35 with only two air-to-air missiles, Major Richard Koch, chief of USAF Air Combat Command’s advanced air dominance branch is reported to have said that "I wake up in a cold sweat at the thought of the F-35 going in with only two air-dominance weapons."[86] However the Norwegians have been briefed on a plan to equip the F-35 with six AIM-120D missiles by 2019.[87]



Former RAND author John Stillion has written of the F-35A's air-to-air combat performance that it “can’t turn, can’t climb, can’t run”, but Lockheed Martin test pilot Jon Beesley has countered that in an air-to-air configuration the F-35 has almost as much thrust as weight and a flight control system that allows it to be fully maneuverable even at a 50-degree angle of attack.[88]



Chen Hu, editor-in-chief of World Military Affairs magazine has said that the F-35 is too costly because it attempts to provide the capabilities needed for all three American services in a common airframe.[89] Dutch news program NOVA show interviewed US defense specialist Winslow T. Wheeler and aircraft designer Pierre Sprey who called the F-35 "heavy and sluggish" as well as having a "pitifully small load for all that money", and went on to criticize the value for money of the stealth measures as well as lacking fire safety measures. His final conclusion was that any air force would be better off maintaining its fleets of F-16s and F/A-18s compared to buying into the F-35 program.[90] Lockheed spokesman John Kent has said that the missing fire-suppression systems would have offered "very small" improvements to survivability.[91]



In the context of selling F-35s to Israel to match the F-15s that will be sold to Saudi Arabia, a senior U.S. defense official was quoted as saying that the F-35 will be "the most stealthy, sophisticated and lethal tactical fighter in the sky," and added "Quite simply, the F-15 will be no match for the F-35."[92] After piloting the aircraft, RAF Squadron Leader Steve Long said that, over its existing aircraft, the F-35 will give "the RAF and Navy a quantum leap in airborne capability."[93]



Consultant to Lockheed Martin Loren B. Thompson has said that the "electronic edge F-35 enjoys over every other tactical aircraft in the world may prove to be more important in future missions than maneuverability".[94]



In 2011, Canadian politicians raised the issue of the safety of the F-35's reliance on a single engine (as opposed to a twin-engine configuration, which provides a backup in case of an engine failure). Canada had previous experience with a high-accident rate with the single-engine Lockheed CF-104 Starfighter with many accidents related to engine failures. Defence Minister Peter MacKay, when asked what would happen if the F-35’s single engine fails in the Far North, stated "It won’t".[95]
