Sukhoi is working on a supersonic follow-on to the Su-25 armored attack aircraft, according to published reports in Yugoslavia.
The authoritative Aerosvet magazine quoted Soviet sources who described the Su-37 as a supersonic fourth-generation combat aircraft called the Shturmovik. Provisional details listed for the canard-equipped plane reveal a 38.71 ft. swept wingspan with a total area of about 538 square feet.
Powered by a single 40,000 pounds-thrust afterburning turbofan, maximum takeoff weight of 55,116 pounds reportedly includes an external weapons load of 18,740 pounds on no fewer than 18 external pylons--plus a 30mm cannon. Low-level combat radius is quoted as 431 nautical miles with an 11,023 pound combat load.
Maximum speed is estimated at 809 knots at sea level or Mach 2 at altitude, with a practical operating ceiling of about 50,000 feet. The Aerosvet report also mentions folding wings for the Su-37, implying possible use for deck operations from the new Tbilisi-class carriers.
Radar "the Beetle" (1986) from MiG-29M, most likelyApparently the radar would have been a set from Leninets called Kinzhal which was also the originally planned set for the Su-39 upgrade and may have been a competitor to the Arbalet system ultimately used on the Mi-28N and Ka-52
I already erased the picture, i agree i should had posted it on the model section, if you have no inconvenience, I made the S-37 on paper and I admit i did not make it 100% accurate because the original model to be honest is just a configuration sketch, i do not think if the aircraft would had proceeded into a real aircraft would had that shape, the windshield frame is more 1960s, than 1990s, the Su-47 Berkut has no frame, it is like Su-27, i think the S-37 would had looked similar to Su-47, well that is my opinion, any way i will post it later if you want in the model section.These are inaccurate models, not suitable for topic.
