"The advantage of the Indian Supersonic Combustion RAMJET (SCRAMJET) engine is the use of hydrocarbon fuel which is cheap compared to cryogenic fuel used by Israel and Russia. Our engine can be switched off, started and used just like a jet engine instead of a rocket engine type approach. This engine is more sophisticated than a jet engine.
