Rocket engines designed by OKB Duslikin, responsible for engines like the one that was used to support the Mikoyan-Gurevich Ye-50.

-It is the S-155 bi-fuel rocket engine that delivered 1300 Kgf. of thrust.

-This MiG aircraft was manufactured to test mixed power plants. The other engine was the "normal" Tumanskii AM-9Ye, later renamed RD-9Ye. It gave 3,800 Kgf of thrust, and later on, this engine was replaced by the AM-11.

-The formula did not prosper as Duslikin's continuity failed.
