Ok, I see some of you don't know much about the IARs (93, 95 and 99), so a few words about these aircraft from a Romanian would probabily help.
Dictator Nicolae Ceauşescu decided in 1968 to bring the Romanian aviation industry back to life, as it had almost stoped existing after WWII, and you've probabily heard of the IAR-80/81 which is considered on of the best fighters of WWII. To limit the dependency of the Socialist Republic of Romania's Air Force on foreign (mostly Soviet) aircraft and technology, Ceauşescu asked for the building of three aircraft types that would meet the curent AF needs at the time: a multirole subsonic fighter-bomber aircraft, a trainer with secondary light attack and fighter roles and a multirole supersonic fighter.
The first two aircraft were designed, built, tested and equiped the AF, but the third project never left the drawing board.
The resulting fighter-bomber was the IAR-93 Vultur (Eagle) or J-22 Orao in Yugoslavia is
not supersonic as somebody here sugested! It's maximum speed is slightly more than 1000 km/h. It no longer flyies for RoAF, but I think the Serbs still use it.
The trainer and light attack aircraft is the IAR-99 Şoim, subsonic, of course and modernized by Aerostar and Elbit. It serves RoAF and will continue to do so for many years to come, as it is a modern advanced training aircraft that allows pilots to train for aircraft such as the MiG-21 Lancer, F-16, F/A-18, Gripen and so on. It also has a very advanced, low-cost, training system capable of simulating weapons, radar (the aircraft does not have a real radar) and threats.
IAR-95 Spey, the one that never left the drawing board did so because it had no engine capable of giving the aircraft the ability of flying at (at least) Mach 2.5. Wind tunnel tests showed that the aircraft would mearly reach Mach 2 (so, more than 1.4, aaaditya
), and so it was redesigned (see the IAR-101, IAR-S projects) and then stoped.
Now, I've did some research, and I've found out, the Romanians wanted to buy an engine for the 95 from China, and that they could have sold the aircraft's plans to them, after the project was haulted, but this is just speculation.
