the f-35s radar is developed from the 22s. this amongst other things persuades me that the f352 capabilities have been significantly played down to achieve funding for f-22.

However, as i recall, the F-35, like the F-16 to the F-15, has a smaller radar than that of the raptor, thus cannot detect as far away.

I'm going to have to pull up my Nomex underpants for this one, but here goes.
Here's Carlo's latest study on the F-35's stealth and survivability vs a modern IADS. It contains some comparisons to the F-22 in various areas, but not in detail.

Apparently he has actually done some independent modeling of the F-35's shape to gain insight into its stealth parameters across a range of frequency bands and aspects.
I don't have the tools or knowledge to know if or what he's missing, but it does appear to be an interesting analysis. He sure sounds like he knows what he's talking about.

No offence, but his "claim" to independant testing is as qualitative as being akin to buying a toy car and then extrapolating drag co-efficients from it...
Again, why would someone who has no access to quality material, who does not even have basic clearances to view military related material and who has historically been shown to manipulate material to support an idealogical case be taken seriously?
Heck, I see more relevant material on JSF at work and I'm not even remotely connected to the JSF team (although they do "live upstairs" and I do deal with them peripherally on other issues)Last edited by gf0012-aust; 08 Jan 09,, 02:35.

It's impossible to model even the RCS alone, without some very complex computing, and you need the exact dimensions and geometry to start with- i.e. the full Catia dataset. That still doesn't contain anything wrt emissions, so even if you had the dataset and computing ability, you would still only have half the picture."We will go through our federal budget – page by page, line by line – eliminating those programs we don’t need, and insisting that those we do operate in a sensible cost-effective way." -President Barack Obama 11/25/2008

But my low opinion of his portrayal of the assets capabilities only serve to reinforce that he's far from balanced (or even remotely aware of what the plane can deliver) . In APA's case (and the other tail coat draggers) it is transparently so.....

If Congress can work it out with the issue of build rates for the Virginias, then its not far removed as a parallel issue for the F-22. (It's not just an issue of looking at cost differences)

It is absolutely moronic for any Govt to even throw that carrot onto the table and expect it to act as a "holding pattern" while they work out how to catch the procurement tiger by the tail.

It also looks pretty decent to the voters to say Ihellped keep these jobs and the facilities of all the little commonet makers in my state.

Originally posted by Maxor View PostI agree when it comes to economies of scale and pricing. Where it is useful is in keeping the production line open with build knowledge and tooling on hand so that if something should happen to decide to scare congress into keeping an airforce that projects power they can quickly ramp up production.

The significant problem with sub building, niche products such as VLO assets etc is that the capability rapidly degrades if sufficient volume and build momentum is not maintained. There is a glaring example of that wrt the UK and the Astutes. The UK discovered that they lacked some of the skills to rectify early build and design problems in the Astutes. The USN ended up providing an industry team to assist. That team leader then wrote a risk paper which went to State, Commerce and SecNav. It eventually filtered to RAN/AustGov because they considered that there were parallels with Collins and the 2020 replacement Project. F-22 is having the same problems, B2 had the same problems (to a lesser extent).
It might keep the general public happy, but in real terms, they are just prolonging the decay of skilled personnel, corporate history and team effectiveness.
