"No PhD here either but the Russians have had what's called a supercavitation missile for quite a number of years. Something about the nose design permits the entire device to pass through the 'bubble' created by it. As I understand it, they're totally unguided but have a huge amount of power to achieve their speed."
I remember reading that the US had alien spacecraft hidden in the Nevada desert. As I understand it, they're lighter then air and travel at lightspeed. Maybe our alien spacecraft can take out their "supercavitation missiles".
How about Phasers and Photon Torpedoes?
