That Hyper Velocity Gliding Projectile sounds nifty.

Scramjets only work at hypersonic speeds (Mach 5+) and the air friction temperature becomes an issue (>1000°C) so they need Titanium skins!

What I don't understand...

" The HVGP, on the other hand, will feature a solid-fuel rocket engine that will boost its warhead payload to a high altitude before separation, where it will then glide to its target using its altitude to maintain high velocity until impact. "

...is why they'd bother to separate? More mass = more damage.

So much for the peace and Zen of Japan.
