As of December 1, 2007, neither Lockheed Martin's nor Hamilton Sundstrand's 2007 news archives show any trace of this award.
Lockheed Martin can issue a subcontract to Hamilton Sundstrand to fix the F135's power generator without any publicity, and they have done so.
Compared with the conventional take-off and landing F-35A already flying, the F-35B has a shaft-driven lift fan mounted behind the cockpit, roll ducts installed in the wing and swivelling nozzle fitted to the engine.
In STOVL mode, doors open above and below the lift fan, a clutch engages to drive the two-stage contra-rotating fan from the engine and the rear nozzle pivots downward to deflect engine thrust.

Lets hope these next test/tethered flights for the B version go smoother the the A versions first couple months. The flights are due to start in the early part of O8 so watch for more info then till then it will be more power on checks and taxi runs for the airframe.
FIRST SHORT TAKEOFF/VERTICAL LANDING STEALTH FIGHTER UNVEILED AT LOCKHEED MARTINFORT WORTH, Texas, December 18th, 2007 -- The Lockheed Martin [NYSE: LMT] F-35B Lightning II, the first fighter to combine stealth with short takeoff/vertical landing (STOVL) capability and supersonic speed, made its debut today amid customers from the United States Marine Corps, the United Kingdom’s Royal Navy and Royal Air Force, and the Italian Air Force and Navy.
Attendees at the rollout ceremony in Lockheed Martin’s Fort Worth assembly plant included Marine Corps Commandant Gen. James Conway. “The flexibility that the STOVL variant of the F-35 will add to the contemporary Marine Air Ground Task Force is amazing,” Conway said.
"The plan is that we will get the F-35 as soon as it's possible," the senior IAF official says. He says the service will end up with more than 100 F-35s, but he would not confirm the size of the purchase or that Israel is asking that the initial delivery date be accelerated by two years to 2012. The IAF wants the JSF "the minute it is available."
Elta, the electronics division of Israel Aerospace Industries (IAI), has a version of the AESA, according to the retired general. "We need our own radar that we don't share with others. We also need our own advanced radar warning and active jamming." The Israeli AESA was flown last year; but for now it remains a generic system, not tailored to any specific aircraft�—although it's sized for an F-16, an Elta official says. Flight trials are continuing.
Another major issue is what comes with the aircraft and what is Israel allowed to develop on its own. Industry officials are struggling with the problem since the F-35 has a highly integrated sensor suite that makes it harder to replace one black box with another. A senior Lockheed Martin official says Israel will not be allowed to simply replace parts of the electronic suite.
However, an IAI executive sees a workaround. The company expects to build JSF structural elements. Once the structure is well understood, there could be opportunities for embedding unique sensors, he says. The information from these sensors could be shown in the cockpit through bolt-on displays if integration proves too difficult.
Originally posted by WestPoint23AA-1 is not representative of the F-35B due to redesign changes made while it was being assembled. BF-1 on the other hand is much closer in comparison to the F-35B, hence why I did not bring t up.
Originally posted by WestPoint23Umm… no LM or the US military has not publically or officially released anything to indicate such. An unconfirmed, unnamed, person (yes singular) claiming to work within the huge F-35 program stating unsupported information is, as I said above, meaningless.
Originally posted by WestPoint23Please quote, you wont because there is nothing but a single passage from a source such as the one I indicated above.
Originally posted by WestPoint23Umm… no it does not, please read up before stating such. What LM has proposed is to reduce the number of test flights due to computer simulations and other advanced means or testing. However that has nothing to do with the structure of the program, or how many test aircraft there will be.
Originally posted by WestPoint23For some refreshing, the X-35 (ABC) were all prototypes because they were the concept and technology demonstrators. They not only had major structural and design differences (from the final production version) but they also used off the shelf technology and systems to simulate advanced ones that would eventually be fielded. And in some case the X series lacked certain systems altogether because it was just a technology and concept demonstrator. It was not a test aircraft by any stretch of the imagination
Originally posted by WestPoint23The F-35 series already had the X-35 initial prototypes and there will be a total of 23 test aircraft (F-35's of all variants) built for various purposes. Of these 15 will be used for flight tests, 7 for non-flight tests and one will be a radar signature test airframe. These pre production models will be thoroughly tested and they do in some forms differ from the final production standard. IOC (at the earliest) for the F-35A is scheduled for 2011, so there will be several years of IOT&E.
A US Air Force test pilot has become the first military service pilot to fly the Lockheed Martin F-35 Joint Strike Fighter. Lt Col James "Flipper" Kromberg flew the first F-35, aircraft AA-1, on its 26th test flight on 30 January.
Lockheed says AA-1 will soon begin aerial refuelling flight tests from its Fort Worth, Texas plant. The first short take-off and vertical landing F-35B, aircraft BF-1, is expected to fly around the middle of the year.
The company has informed employees at the Fort Worth plant that it expects to take some 850 engineers off the JSF programme this year as design work on the F-35 winds down. This is expected to result in some 650 jobs being cut, beginning in April.
Of the total, $45.6 billion is for aircraft development and procurement. The FY2009 request funds for procurement of the Lockheed F-22 and F-35, Boeing F/A-18E/F and EA-18G, and Bell Boeing V-22 at or close to planned levels.
Congress overturned the DoD’s bid last year to cancel the alternative JSF engine by adding back the full $480 million in funding for FY2008. This will take the money spent on F136 development to $1.3 billion of a planned $2.4 billion, says the GE/R-R Fighter Engine Team.
FY2008 will be the peak year for spending on F136 development, the team says, with $440 million required in FY2009 to keep the programme on schedule.
The failure of the low pressure (LP) turbine blade is thought to have occurred in engine six which was undergoing flight clearance "proof test" ground runs prior to installation in the first STOVL F-35, BF-1.......
The August failure, which contributed to a prolonged delay for both ground and flight tests of AA-1, the first conventional flight test F-35A, was traced to an unsteady flow regime in the wake of the stator upstream of the LP turbine third stage.......
According to information revealed at the December roll-out of the BF-1 in Fort Worth, Tex., the aircraft was expected to make its first flight from a conventional take-off roll in late May or early June. This was to be followed with a gradual "build-down" to STOVL tests by around the end of 2008. It's unknown right now if and by how much the recent failure, which occurred on Monday, will affect the F-35B test schedule.
In the meantime it cleared specific engines to allow flight test to resume of AA-1 in December 2007, and hoped tests of engine six would similarly clear the way for BF-1 to start tethered hover pit tests originally set for April.
The tests were aimed at proving, on an engine-by-engine basis, that the specific unit was safe to use in BF-1, and that it did not exhibit the same combination of assembly characteristics, tolerances and other factors that led to a similar failure on a test stand engine on August 30.
P&W is developing a fix involving redesigning the stators and is planning to test the improved configuration by the middle of this year
