Antiproton drive

Antiproton drives inject antiprotons into a chamber filled with hydrogen or another cheap propellant. The resulting annihilation produces a massive amount of thrust. Antiproton drives are installed on military ships alongside fusion drives.

Antiproton drives are used by military vessels when they perform maneuvers requiring more acceleration than a fusion drive can provide.

The primary drawback of antiproton drives is fuel, antiprotons are difficult to produce.
