O rly, and who is your source on this. GAO? :lol:

If the RAM was being applied to new-built F-22s than it would not show up in the budget. Later, if they decide to re-RAM the rest of the fleet, then it will show up.

Ada is not running inside the radar itself, just the F-22 main computer.

Besides, I did not say the same software was running on both fighters. What likely is taking place is that modes (especially A2G) being developed for the APG-81 are being re-coded for use in the the APG-77. The actual software is not what is the hardest to develop, but the algorithms that are used to build images. Also, ECM & ECCM features developed for the APG-81 are likely being shared with the APG-77.

IF one looks at the first post on page one of this thread one may see a connection - sadly not much detail forthcoming.
Lockheed Martin gets $40 million contract to recoat Air Force F-22 Raptors
20 Mar 2017 Christopher Diamond

"The Lockheed Martin Corporation has received a $40 million contract modification to strip and recoat the U.S. Air Force’s F-22 Raptor Fleet. Under the new agreement, Lockheed will strip and recoat the stealth fighter jets, with an expected completion date of June 20, 2019, according to the Defense Department.
"Lockheed Martin Aeronautics Co., Fort Worth, Texas, has been awarded a $40,062,000 modification (P00797) to previously awarded contract FA8611-08-C-2897 for F-22 sustainment. Contractor will provide proofing of time compliance technical orders created to strip and recoat coatings that are reverting on the F-22 fleet earlier than expected...."

Lockheed established an F-22 Inlet Coating Repair Speedline facility in Marietta, Georgia, last August under an Air Force contract. The first F-22 arrived there in November, according to Lockheed Martin. The original contract had Lockheed recoating 12 F-22s and the first plane was returned to the Air Force in February. The new contract modification will have all F-22s with reverting coating stripped and recoated...."

Must be quite a savings to re-coat the entire fleet. That's good news though, and like the General said - would be surprised if it didn't improve its already impressive RCS signature.

These upgrades to the F-22 are heartening. We may only have a silver bullet fleet, but keeping it ahead of the threat(s) is where it's at. The more we can do that, the more we can let the F-35 focus on its intended strike mission(s). But damn, what I wouldn't give for 200 or so more Raptors.. :)

You've actually merged to topics together that deal with its coatings.

The strip and recoat that the article is referencing is for the intakes due to coating life cycle replacement. The jet is not getting completely restriped to apply F-35 coatings. There has been some cross pollination to help improve the maintainability but it is not a complete aircraft recoat. The article is a bit misleading.
