Talk:Hypersonic Air-breathing Weapon Concept

Ist hypersonic test - details to look for
What aircraft launched the missile? Did the missile also have a rocket engine to get up to scramjet ignition speed ? How long did the scramjet fire ? Was it able to increase speed ? - Rod57 (talk) 12:42, 4 October 2021 (UTC)

Purpose of HAWC
I think this page could use a section on why HAWC exists, given that its range and speed seem similar to short-range ballistic missiles. I believe the answer is that flying at low altitude makes it harder to shoot down. I wasn't able to find any information that says it carries a larger warhead. Intuitively an air-breathing engine might be more efficient than a rocket because it harvests propellant from the atmosphere, but it also experiences much higher drag. The DARPA press releases give hardly any information, so better citations would be valuable. 104.246.222.63 (talk) 21:47, 8 April 2022 (UTC)
