    That’s an overly simplistic look at it.

    The F-35 program (and others) use and have used this process in the past. The only thing happening now is that the program is saying that the sims have caught up with teh original plan.

    Much of the F-35 test points were always meant to be done in a sim. When the sim could not reliably replicate IRL events earlier in the program, Gilmore added more IRL tests.

    The only thing the JPO is saying is that now that the sims have caught up to IRL tests in their accuracy, certain test points can be safely done in the sim instead of IRL.

    It was not an “open panel” that allowed the F-117 to be hit, it was:

    — Poor mission-planning (flew the same root repeatedly)
    — Good EW discipline (did not leave the radar on)
    — Poor situational awareness (no RWR in the F-117)
    — Good intel (spotters along the route)
    — Dumb luck (he flew directly at the radar unit)
    — Short range (he was hit at less than 10km)

    Here is a closeup of the panel involved. What is clear is that it’s a non-powered door (ie you have to open it manually and even have to “prop” it open).

    Details on AdvEOTS has not been released yet. There are a few items that can be found like it’s going to be NIR/SWIR (two sensors), larger aperture, fit within the same sensor bay, etc.

    To be fair, it was mostly due to economies of scale as they were offering 126 Eurofighters vs only 36 Rafales.

    I think that the only RECCE function that the F-35 will not do as well as a dedicated pod is optical. This will hopefully be somewhat addressed in Block 4 with an AdvEOTS sensor (more details due in Feb with the budget plan). In the ESW spectrum that are few better options with the F-22 & maybe the Growler among them. It’s very telling that at several Red Flags, F-35s have been asked to stay in the AO after expending weapons in order to support the rest of the force with it’s sensors. It’s software-defined CNI also plays a big part in it’s ability to soak up data in RECCE role.

    Sorry, it was after lunch and I was slipping into a food coma.

    If you have decent error handling and a good IDE then it’s manageable.

    I almost forgot, it makes extensive use of VMs & middleware (makes errors less likely and easier to recover from) and even it’s 8×20 display is actually two 8x10s side by side. They are electrically separate so if one goes down completely, the other can take over the duties.

    On a related note, the build rate for the F-35 by 2020 can be up to 160.

    Not to mention how well Venezuela is thriving under Socialism.

    Correct, the Last “Fort Worth” F-16 rolled off the line this month but the line is moving to Greenville.

    But it’s the end of the line for Tamplin and the Fort Worth F-16 production line. To make way for growing production of the F-35 Lightning II joint strike fighter, Lockheed is moving the F-16’s assembly line to Greenville, South Carolina. While engineering, design and modernization activities will remain in Fort Worth, the last Cowtown jet flew out of town Nov. 14.

    My phone has more processing power than most fighters flying today. Its cost is MINUSCULE compared to PCs 20-30 years ago. I remember seeing a 486 PC from the late ’80s that cost $5000 ($10.8k in today’s dollars). My new PC is a BEAST (8c/16t @ 4Ghz), 16GB RAM, 500GB M.2, 8TB Raid10 SSHD, 1070GPU, Dual 27″ 1080P and cost less than $3k. It has to power to run multitudes of what is needed in the F-35. The computers in the F-35 are much cheaper than is in the F-22 or any other fighter when the functions that it does are compared. One of the reasons why the F-35 uses C++ is to keep the processors cheap and the development time low.

    Btw, a majority of the code for the F-35 is actually running in the ALIS system (ground-based) rather than on the F-35 itself.

    Numbers don’t lie, no matter how you want to twist them. Several countries have compared the F-35 to Rafale, Eurofighter, et al and the F-35 came out on top, including price. Don’t get caught up in early LRIP pricing but look at the trend in pricing (getting cheaper every day).

    I think the F-16V with CFTs, AESA, ESM, etc is a good option and is flying today (as opposed to the “advanced” super Hornet).

    when did Denmark fly the F-35 and test it in real time?

    They never did and the reason is simple, there are only single seat versions. They would have to have pilots go through the training program before they could fly it (the same applies to the F-22).

    Don’t get me wrong, I would love to see the details of a side-by-side, apples-to-apples comparison between all competitors (Rafale, SH, EF, Gripen, etc) but understand that most numbers will come from the bidders rather than hands-on evaluations.
