This is a research paper on various air-to-air missiles.
A normal rocket engine has a terminal velocity of 312.4 m/s. (AIM-120)
The double pulse engine has a terminal velocity of 821.1 m/s.(PL15)But the average velocity is going to go down.
The Meteor missile uses a ramjet engine and its terminal velocity is lower than 312 m/s.
At the same time, we can see the importance of supersonic cruise. The 4gen fighter has no chance against the 5gen fighter with medium-range missiles.Stealth approach, missile launch, supersonic escape.
