The launch in May was the first time that the Meteor's propulsion system had been fully tested under real-world conditions.
The firing was intended to verify the missile's ability to transition from rocket-boosted to ramjet-powered flight. The Meteor is powered by a solid-fuel throttleable ducted ramjet motor,developed by Germany's Bayern-Chemie. The missile is designed to sustain a speed of M4.0 over its 100+ km engagement range.
What does the ramjet system do?
Mach 4 constant... sexy
