Unknown by many right now (because of how new it is) SAAB is starting the first domestic stealth aircraft project, really looking forward to seeing the outcome. Dubbed the FS2020
The IAI Aryeh, an Israeli stealth 4th generation fighter capable of mach 2.7, as agile as the F-16, capable of cryying nukes and so on. The concept was amazingly advanced for the time (1975-1981), but it is not known till this day if this wonder was ever built (it could have got one prototype, but of course no one knows that for sure). The IDF does not share information, so we don’t know if this Israeli unique F-15-but-better-in-every-way was built or not. I suggest we get it anyways, we already have Ho-Ri and Ostwind II.
The Strv m/41 S-III Torn A Alt 1, one of 4 alternatives proposed by Landsverk in 1943 taht were based on a heavily modified Strv m/41 and made as a response to the Soviet T34’s inspected in Finland.
