Really? News to me! Ramjets have been used to power missiles since the 1950s and don’t stop to allow the missile to manoeuvre.

I suspect that the reporter has misunderstood what he was being told. One problem with ramjets is that the motor may cut out if the flow of air into its inlets is disrupted by a sharp manoevre.

I was thinking the same , why would missile stop its engine while manouvering and start in flight , well a missile manouvers quite a lot of time if not in flight then during terminal manouvering.

I wonder if they can stop and start a liquid fuel ramjet in flight.
