Mikulin R-15B-300
The single-jet, single-shaft R-15B-300 engine was developed in the early 1960s by A.A. Mikulina based on a 15K engine for the needs of projected high-sound means. It was originally considered to use the engine of a planned missile with a flat flight path, but in the end the engine was used in the project of supersonic fighter E-155.
