The S-32 was a conceptual fighter aircraft. It was a paper-only concept airframe of the Su-47 Berkut technology demonstrator, which never materialized as an actual fighter. A "predecessor" of the Berkut, the main differences between both aircraft lie in the S-32's inner-cranked vertical stabilizers, engine design and Sorbtsiya wingtip mounted ECM pods.
Complete multiplayer Joint Assault mission 3&4: Red and Black on the second playthrough or complete mission 20: Ghost Hunt on the second playthrough. Costs $102,800.
"A prototype of the Su-47. Despite its outstanding maneuverability, development was discontinued. Its potential as an extraordinary fighter is limited only by the skill of its pilot."
