Advanced Propulsion Systems

This Mod adds several advanced propulsions systems and is roughly oriented on real world cold war research projects. Such as nuclear propulsed rockets(actually produced and flown!), hydroelectric submarines without moving parts and nuclear powered aircraft. These are intended to be expensive endgame units. What you get in Detail: Several researchable Technologies: -Nuclear Rocket Propulsion Tech: buffs your ICBS with unlimited range but doubles their price. -Advanced Reentry Heat shields -Ultra High Altitude ICBMs: Nearly impossible to intercept -Ragnarök 100M ICBM has its own special Silo. -Magnetohydrodynamic Propulsion Systems: Ultra Silent Phantom Subs -Nuclear powered aircraft with unlimited range (AWACs and Bombers)
