The "Berkut" ("Golden Eagle") of 1997 (formerly referenced as S-32) took place of smaller single-engine S-37 project of 1991. It looks like a radical revision of dedicated aircraft line Su-27-Su-37. It has a layout of tandem triplane with forward swept wings and thrust-vectoring engine (equipped with digital control system). This combination provides exceptional maneuverability, what in conjunction with elements of stealth technology and new more powerful engines can provide Russia with a superior aircraft for 20th century.
While forward-swept wings are not a best choice for supersonic performance, while provides great advantages at high angles of incidence and in post-stall maneuvering much needed in close-in dogfight, as well as missile evasion. This approach radically differs from USAF concept of stealth, supercruising and beyond visible range (BVR) combat. RAM coating is chosen for stealth contrary to American F-22 radar absorbing structures (RAS).
There are several riddles surrounding this aircraft.
High speed taxi trials completed in Summer 1997, and maiden flight took place September 25 at Zhukovsky in hands of Sukhoi's test pilot Igor Votintsev.
It seems realistic that series fighter will emerge under conventional Su-** designation.
