    Unfortunately I do not trust the current US Congress to be wise, practical or forward looking in most dealings with the military. I actually trust the defense contractors more. Especially with the current administration that buys votes by cutting defense.

    Good news!


    PARIS: Pratt & Whitney fixes STOVL problems on F-35B
    [*******#30256d]Pratt & Whitney[/COLOR] believes it has solved the three problems with the lift-fan system on the STOVL variant of the [*******#30256d]Lockheed Martin[/COLOR] [*******#30256d]F-35 Lightning II[/COLOR].
    The issues were highlighted by US Secretary of Defense Robert Gates earlier this year and included the lift-fan driveshaft, roll-post nozzles and lift-fan clutch plates.
    Both short- and long-term fixes are now in place, said P&W, whose F135 engine powers the fighter
    Bennett Croswell, president of military engines at P&W, said that in the case of the long-term change to the design of the driveshaft, it has actually cut production costs.
    The engine manufacturer says it is still setting "aggressive goals" for cost reduction in line with an affordability plan agreed with the Department of Defense in 2009.
    "When we look at that plan we are either in line with or the cost is lower than it," said Croswell.
    However, he said that P&W is working with Rolls-Royce (chalet B89), which provides the lift-fan system, to "mitigate any kind of cost increase that will come from the substantial decrease in volume" due to a reduction in orders for the STOVL variant this year. Only three F-35Bs will be produced this year, down from a planned 17.
    It cut the cost per engine by 15% between LRIP3 and LRIP4, said Croswell, and expects another fall for the LRIP5 contract,

    F-35 tested "virtually" at Alaska's Norther Edge exercises using BAC-111, Blk3 software, & EOTS/EODAS hardware.

    Early results from the use of the F-35 Block III software are good after the Air Force used it during a recent Northern Edge exercise, ...

    During the exercise, the software was pitted against various operationally representative threat systems. Moore says the EO/DAS system was able to track objects 360-deg. around the aircraft. This data was also properly displayed into the cockpit, he says.

    They also had the APG-81 & data-links as part of the tests.

    Participating in the Northern Edge exercise for the second time, the AN/APG-81 radar demonstrated robust electronic protection, electronic attack, passive, maritime and experimental modes, and data-linked air and surface tracks to improve legacy fighter situational awareness.

    Due to better performance in flight testing and test points, the USMC is pulling 2 F-35Bs from the schedule early to get them ready for shipboard certification this fall. They also see IOC as late 2014/early 2015 for the F-35B.

    Talk about an about face! I wonder if there's any chance we'll see the general F35 going back down from 2016 if the current progress continues.

    ^ Great vid. I remain highly optimistic concerning the F35 (and the F22 as well). What modern American fighter aircraft has come on line, and to a certain extent not been a development in progress for its first 10 yr in service? The levels of technology are advancing much faster today than in the development period for the F16 and F15, and I would think that is one of the major causes for delay.

    Thales Australia and Nammo have signed a long-term strategic teaming agreement to cooperate in the ordnance market.

    The 10-year agreement expands on many years of cooperation between the two companies, and builds on a 2010 commitment to work together on ammunition for the F-35 fighter program, in particular on the Armor Piercing EXplosive (APEX) Norwegian ammunition concept. The agreement also covers Nammo’s special Reduced Ricochet Risk training round, plus Thales’s Armour Piercing Fragmenting & Incendiary (APFI) ammunition round.

    Northrop completes centre fuselage for second Dutch F-35
    Northrop Grumman has completed the centre fuselage for the Netherlands' second [*******#30256d]F-35A Lightning II[/COLOR], with the aircraft to be used in support of the Joint Strike Fighter programme's operational test and evaluation phase.

    Pictured at Northrop's Palmdale manufacturing centre in California, the structure will be transported to Lockheed Martin's Fort Worth final assembly line in Texas. It will then be integrated with the other major sections for the conventional take-off and landing aircraft: its Lockheed-produced forward fuselage, cockpit and wings; and BAE Systems-built rear fuselage.
    [IMG]http://i51.*******.com/2hn856gdotjpg[/IMG]
    The Netherlands late last year confirmed its plans to buy the second aircraft, following a change of government.

    Northrop said it has so far delivered 48 centre fuselages for F-35s, with this total including flight test aircraft and low-rate initial production examples.

    Again, I am grateful for the response. But it still doesn't answer the question.

    My basic considerations are these: We'll imagine Britain buys, let's say, 100 F-35Cs. A couple of years go by and Britain knows that the U.S. has updated the software. But Britain has been required to despatch its carrier(s) to the South Atlantic to protect the Falkland Islands. I reckon a software upgrade could be transmitted to the carrier over a secure datalink. On the other hand, if the Americans won't release the source code, the only way to upgrade our aircraft is to (a) fly them to Italy or (b) fly them to wherever in the U.S. Neither option seems very sensible.

    It was my understanding that the constant stumbling block was Congressman Henry Hyde. I am aware that Hyde has now left the Congress but has anybody stepped into his place? Will Britain be given the source code to enable it to maintain its own aircraft at the peak of their capabilities?

    If it's not going to happen, there is no point in buying them. Navalising Typhoons, that are only Mach 0.1 slower, would be a far better option.

    They haven't even finish writing the damn code yet. The F-15, F-16, F-18, etc. with whatever code they had were never fully released on exports and the JSF will be no different. There isn't going to be any secret or back door kill switch, hardware or software, or any blocks or whatever else to make it an inferior "export" version.

    Some of these code will never be fully released because they are proprietary data that took years and billions of dollar in R&D that deal with how well OUR systems communicate with each others. You won't get them and you won't need them because on top of the fundamental code that EVERYONE will get regarding how the aircraft operate at its peak, you will write in YOUR own proprietary code because obviously your weapons and other systems will not always be the same across the board for every operators of the JSF. The Israelis already said they wanted their own stuffs in the JSF, so obviously no one else is going to use their code and the IDF doesn't need the U.S. version of it. The trend will be the same for everyone else.

    Navalising the Typhoon would be a more-or-less completely new aircraft. Not going to happen.
