Flanker 2.0 is the second major release of SSI's realistic air combat simulator based on the Russian Su-27 & Su-33 Flanker. Like its predecessor, the game features a comprehensive simulation of the jets' avionics and weapons systems, with a focus on beyond-visual-range air-to-air combat. Mastery of the Flanker's various radar and weapon systems is essential to the player's survival, a task made all the more difficult by the fact that the instrumentation is entirely labeled in Russian.
Improvements for this second release include 3D accelerated texture-mapped graphics and the addition of the Su-33 naval variant of the Flanker. The main difference would be that the Su-27 is a pure air superiority fighter while the Su-33 retains a ground attack role. Beyond that, however, there is little difference between the two planes.
The game underwent several updates, culminating in version 2.51. Incremental improvements included flight model and weapons model revisions, graphic and stability enhancements, the addition of wingman commands, and the ability to fly the MiG-29 jet fighter.
