    There has always been a plane to integrate the entire military into a big sensor net. This is not a new plan and the US Army is not saying that they want to buy F-35s or use them as a “primary” sensor. They are only saying that while they are up there, it would be nice to have the data.

    The USAF did post “Non-Recurring” (YELLOW Lines in the pic below) costs for the F-35A in the latest budget docs ($7.8mil)… they just added it in as part of the “Recurring costs”.

    Go back a few years and you will see how it was supposed to be listed (ie after Recurring costs)

    Here is the current USN Budget shown with the numbers in the correct location.

    Superbug – $96.3 mil a pop, surprisingly expensive, IMHO

    Don’t forget that this does not include wing tanks, a FLIR, or an IRST which brings its price right up there with the F-35A.

    Keep in mind that there was an artificial 5% SDD fuel buffer that is being removed since SDD is ending this year. This is the likely reason why it got a large jump in range for the FY2018 SAR.

    The equation does not include a buffer margin of 5% of fuel capacity, which is intended to be preserved through the end of the flight test period in 2016. Eliminating the buffer margin adds another 72.4km to the aircraft’s combat radius, the source said.

    They can probability upgrade existing stocks and save a butt-ton of money.

    Is the Sopwith relevant today, no….

    So why bring it up?

    If it’s a large/slow/high flyer then it not a “fighter”, it’s a surveillance drone.

    SI2 can only go max speed 87mph while being 25% batter pushing 80hp worth of motors.

    For comparison’s sake a GE F414-400 engine produces 65 times that HP.

    It cannot be done.

    The only way that an electric fighter can ever be done is nuclear and even then it would require a massive miniaturization of the power plant, especially if it’s a manned platform.

    Um.. Why are you linking WW2 fighters in a discussion about a solar & battery powered fighter????

    Solar Impulse flew 50mph with 270m^2 of solar panels while weighing 5000 lbs.

    A fighter would have a significantly smaller wing & weigh significantly more while powering a significantly less efficient power plant not to mention that a fighter has to fly at night, in bad weather, etc. Hell, just turning drops the solar collection values significantly.

    You are seriously high if you think that a fighter sized aircraft can be powered from solar & batteries.

    Did you just say “solar energy” in the same breath as “high speed”?

    Do you do any research before opening the brain drain and letting the ideas out? :very_drunk:

    I don’t see how this can make any difference since it would be the same amount of watts being removed from the engine.

    Energy density is the biggest issue. You just can’t store enough energy unless you somehow did nuclear.
