Is it not ground launch cruise missile? Its flying above cloud. This is why i ask expert?
Please list name of 1 ground launch Subsonic cruise missile which fly above cloud.
Whats the benefit of 2.5KM height for subsonic cruise missile??? Logic of Terrain hugging mode for subsonic missile is very simple to give very minimum time to enemy to response. Enemy will be able to pick missile when its very close to its target. You fly missile at 2.5KM they will know its coming and that distance & speed i highly doubt any success.
