Ramjet engines cannot propel an aerial vehicle from
zero to supersonic speeds.
Ramjet, ScRamjet and Dual Mode Ramjet(DMRJ)
are the three concepts of air-breathing engines which are being developed by various space agencies.
A scRamjet(supersonic combustion Ramjet) is a variant of a Ramjet airbreathing
jet engine in which combustion takes place in supersonic airflow.
Design of the missile is similar to that of the SA-6,
with four long tube Ramjet inlet ducts mounted mid-body between wings.

News of October 29, 2019- The SABRE engine must
be able to function as a turbojet engine, a Ramjet engine or a rocket engine.
Unlike conventional rockets that carry propellant and oxidizer, Ramjet uses the air as an oxidizer just like a jet engine, and hence,
the weight of the fuel required is eliminated.
