Rocket engines are not their only business. What operational rocket does
the US have compared tot he Russian Proton?

Dunno. Haven't researched it that thoroughly.

Why is the US using Russian engines?

Cheap?


The shuttle does move more gear and people. The Shuttle's big flaw was
building the engines into the airframe.

I wasn't aware of that. Why is that so?

Advanced tactical laser to fly soon.

What's the power source these days? Nuke?
