The Lockheed Martin F-35 will run on a Harris-built integrated core processor (ICP) beginning in 2023, the two companies revealed Thursday.

The new ICP, the "brains" of the advanced fighter, promises 25 times the processing power at one-fourth the cost, according to Harris, and is built on an open-system architecture to enable easier future additions or upgrades, which fits in with Lockheed's and the U.S. Defense Department's goals.

... am still interested in a reaction to what I asked
Today at 7:40 AM

In my view your question was rather pointless and why I did not address it initially. Since you are insisting, I would be direct.

Whether it is trillion or billion of flops is irrelevant to me. It has no perspective regardless of the answer. It is a rather myopic view of a subject driven by ignorance of a technical subject we can hardly claim to understand. The source of the F-35 EW capabilities is not because its GPU can handle billions or trillions of calculations. It is a sum of its different sensors and its fusion supported by a databus architecture (Mil-Std-1394) processed by dedicated FPGAs, signal processors and directed by the millions of line of codes. All the leading edge stuff cost money and time and why it ended up with a $60 plus billion development budget and nine years behind schedule. Leading edge capabilities don't come cheap. If you want development on the cheap go to Russia. There is general 2 of 3 rule in acquisition. Fast, cheap and good. Pick any of two. If it is fast and cheap it is not good. if it is cheap and good it is not fast. If it is fast and good it is not cheap. In other words, you get what you pay for.

The F-35 basically went for a completely new leading edge bus architecture because sensor fusion requires high data throughput and nil latency in data exchange. Mil-Std-1553 just can't deliver that. High end development require tons of money.

There are a bunch of things to consider ; deterministic behavior, weight, power, volume, latency, topology robustness, software impact, hardware development risk, Failure Modes and Effects Analysis (FMEA) risk assessment, tech refresh path, both non-recurring and re-occurring costs in any design. It is just not a case of calculations per sec.

If you are claiming how capable your avionics and sensors are and my first question would be what is your avionic databus? It is not how many trillions of calculations your GPU can perform. The fact is the SU-35 is still using Mil-Std-1553 and the J-10 is using ARINC 429 speak for itself.

A well written article on the F-35's EW features.

Bro, I think you need to give people some slack until proven otherwise. This is just a hobby to pass time.

There isn't any thing new that the author said in the article that we do not know. The EW features of the F-35 is probably the most guarded among its capabilities. The most interesting in my view is its EA capability.

Okay
warning the following is a report by the Heritage Foundation a conservative American think tank and may contain views and opinions likely to conflict with the readers. Readers are recommended to leave but hurt at the door and read the report for its factual content and not the political viewpoint of the page or foundation Butthurt discretion is advised.

Now part of that report is based on polling pilots of the machine, including comparisons of experienced pilots to there previous machines. As such comparisons are made in a number of fields comparing the F35A to F15E,F15C,F16C,A10 and a former Raptor driver. Also polled were new pilots who came right into Lightning with no real previous fighter experience.

I compared the results from am earlier report dated August 4,2016 against this report dated May 14. 2019. The sample size are almost similar 31 vs 30 and the results as well.

Report dated May 14, 2019 (overall sample size 30)
upload_2019-5-19_12-52-39.png
Report dated August 8, 2016 (overall sample size 31)

I thought the result is rather unexpected as I was expecting the later report to reflect probably a better assessment as it would reflect a flight envelope lifted 3F experience.

In the latest report at least we have a description of the F-35 geolocation capability.
When a single F-35A detects the emission of a threat, it records the azimuth to the signal from a designated point in space. As the jet continues on its flight path, it captures the azimuth to that same signal at a different point in space, allowing the jet to automatically calculate the geographic location of that threat based on trigonometry. As the math goes, the greater the angular difference between different azimuth traces, the higher the accuracy of the target location.

Flights of F-35As are linked through the system’s multifunction advanced data link (MADL), allowing the azimuth traces of those detected threat emissions to be exchanged and paired, and their locations to be calculated automatically. The accuracy of the target location goes up markedly as the angular difference increases between those two points. That angular distance in a formation is created with the spread (distance) between F-35As in a formation. The wider the spread, the greater the azimuth angles, which deliver more precise geolocation.
I was speculating (wrongly) that the geolocation capability was more advanced by just relying on a single signal emission but geolocated via the integration of the distributed sensors on board the plane.
