    Pentagon report cites "lack of maturity" of Lockheed F-35 jet

    (Reuters) - Lockheed Martin Corp's's new F-35 fighter jet has completed over a third of its planned flight tests, but it is still facing problems with the helmet needed to fly the plane, software development and weapons integration, according to a report by the Pentagon's chief weapons tester.

    The 18-page report, sent to Congress on Friday, included a detailed account of those issues and others, which it said underscored the "lack of maturity" of the $396 billion weapons program, the Pentagon's most expensive ever.

    The program exceeded the number of flight tests and specific system tests planned for 2012 but lagged in some areas due to unresolved problems and newly discovered issues. The program has already completed over 20,000 specific tests of items and capabilities on the plane, but has 39,579 more such tests to go.

    The report highlighted the continued growing pains of the ambitious Lockheed fighter program, which began in 2001 and has been restructured three times in recent years to slow down production and allow more progress on the development program.

      Whoever wrote that had an almost British sense of understatement.

      •  Reminds me of the F-111B (9+ / 0-)

        F-111B

        The weight goals for both F-111 versions proved to be overly optimistic.[13] Excessive weight plagued the F-111B throughout its development. The prototypes were far over the requirement weight. Design efforts reduced airframe weight but were offset by the addition of the escape capsule. The additional weight made the aircraft underpowered. Lift was improved by changes to wing control surfaces. A higher thrust version of the engine was planned.[14]

        Requirements for the F-111B had been formulated before air combat over Vietnam in 1965 showed the Navy had a need for an aircraft which could engage fighters at close range. The Navy desired a fighter with more performance than the F-4 Phantom II, yet in trials, the maneuverability and performance of the F-111B, especially in the crucial medium-altitude regimen, was decidedly inferior to the Phantom.[citation needed] During the congressional hearings for the aircraft, Vice Admiral Thomas F. Connolly, then Deputy Chief of Naval Operations for Air Warfare, responded to a question from Senator John C. Stennis as to whether a more powerful engine would cure the aircraft's woes, saying, "There isn't enough power in all Christendom to make that airplane what we want!"[15]

        With the F-111B program in distress, Grumman began studying improvements and alternatives. In 1966 the Navy awarded Grumman a contract to begin studying advanced fighter designs. Grumman narrowed down these designs to its Model 303 design.[16] With this the F-111B's end appeared near by mid-1967.[17] By May 1968 both Armed Services committees of Congress voted not to fund production and in July 1968 the DoD ordered work stopped on F-111B.[18] A total of seven F-111Bs were delivered by February 1969.[19]

    •  Design Evolution... And Bloat (7+ / 0-)

      The F-35 was intended to be all things to all services. However, that means designing it to be good at most things, instead of great at one thing. And then add in that it's a multi-government procurement that was designed by committee.

      For example, the history of the procurement for the Bradley Fighting Vehicle is an interesting one to read about.
