    Jeff,

    I think you are running a bit ahead of the curve on production numbers. The 521 airframes will likely be the number flying if you include Lot 11 production run but that won't happen entirely until end Dec 2019. Until then the number is closer to around 360 plus by my count. Additionally of the 360 plus flying, 108 are not up to the 3F standard and would require various retrofit which unfortunately are unfunded and given the politics may not happen. That will be a shame..

    An article from Avionics International describing data fusion with the F-35.

    https://www.aviationtoday.com/2018/09/04/f-35-data-fusion/

    What is noteworthy is a description of the fusion protocol between an individual F-35 and a F-35 sensor formation through a tiering architecture. This is the first time I have seen such description in any public literature.

    The tier approach provides some clarity in how data integrity are maintained between an individual F-35 and a formation when it comes to COP. The article talks about a "network" that generates the Tier 3 data without explaining "who" or "what" is this in reference to. The only platform within this network that has data fusion capability would be a F-35. I would speculate that a lead/designated F-35 would be responsible for it. If this is the direction it also means that there is a switch to flip the fusion battlespace presentation between Tier 1 and Tier 3.

    sounds like an ad


    how do they segregate into "Tiers"?

    plus, what would happen if wrong info went into their "Tier 1"?

    and Brumby something from real world for you:

    The sensor fusion architecture of the F-35 is based on centrally fusing the data. This means that after the respective sensors e.g. EOTS, EODAS, AN/APG-81 and AN/ASQ 239 have vacuumed the raw data, they are not processed at the sensor nodes but instead channeled to the fusion engine (core processor). The threat picture and tracking data are build based on the fusion of all available raw data. The fusion process is driven by a set of algorithms and the reason for the millions of line of codes. The outcome of the battlespace picture is the tier 1 data. If certain sensor data is corrupted by noise from electronic counter measures, the idea of fusing all raw data derived from source helps to isolate bad data from individual sensor. In a sensor formation of typically four F-35’s, each will derive its own tier 1 battlespace presentation. When the tier 1 data is then shared within the formation, this is when the tier 3 battlespace picture is made available. Once at tier 3 layer, all the F-35’s will share a common operating picture (COP) of the battlespace and if there are any link back to C2, the same COP will be available.

    funny what he says now:
    The Air Force Wants to Buy More F-15X Jets, and It’s a Huge Mistake https://www.heritage.org/defense/co...ants-buy-more-f-15x-jets-and-its-huge-mistake


    (back then
    "John Venable, a senior research fellow for defense policy at the Heritage Foundation who helped craft the proposal, told reporters during a private breakfast Tuesday morning that the decrease in the Air Force's purchase plan for F-35As would free up money for different acquisition programs within the service.")

    at what point in:
    would Mission Data Files come into play?
