The F-111 can be 'stealth' but the aircraft itself is not low radar observable, at least comparatively to the F-16 class. To be 'stealth' mean you must avoid radar detection by any means, except via ECM. Flying below the radar horizon definitely qualify you as 'stealth'. The word 'stealth' have been too casually used and abused.
I agree, it gets abused a lot and it is the case when they call our 1,400 ton warship a "destroyer", i watch the Persian announcements by the generals and they make no such claims then i read the English report and they call it stealth, as opposed to "able to avoid detection" or "reduced RCS", they also translate the word "warship" in Persian to "destroyer" in English. Journalists are the same all over though, they were calling an APC a Tank on BBC yesterday.
That is true. With enough money and time, of course Iran would be able to make a very low radar observable aircraft like the F-22, perhaps even better.
Nice sarcasm, but if you factor in the fact that we've mentioned that the word stealth is overused, and if you factor in the fact that Iran makes 70% of the F-14 (minus certain avionics and certain parts of the engine) and if you factor in the ToT of the Shafaq and the MBB Lampyridae projects and the FBW plus other technologies gained through the IrAn-140 project, and their respective infrastructure being built, it isn't an exaggeration that if they allocated enough funds to the Air force then we could see a decent plane. This won't happen until the regime believes that they're not under threat anymore, because at the moment, we could spend tens of billions and develop something quite capable, but it would still be no match against America and their cruise missiles, F-22s B-2s etc. Therefore there is no point. So as soon as the threat from America is gone, you will see more conventional projects being built, at the moment they're all concepts (Raksh APC, Zolfigar tank, Dorna advanced trainer). The things that are being built are anti air/ship/tank missiles, UAVs, BMs, Fast attack craft and submarines.
Size has a great influence on how low radar observable is a body. Remove the need for pilot support and you reduce body size by at least %40. On the other hand, if body shaping is not considered, then size is irrelevant.
This article is about a UAV that Iran is working on with RCS features and RAM. Body shaping is not too difficult, it was difficult to design before Supercomputers, noways you can build supercomputers by using PS3 CPUs
