Anti-Matter Initiated Nuclear Pulse Propulsion .
Compressed deuterium & helium-3 pellets are fired into the combustion chamber where they are bombarded by electron beams, thus initiating a thermonuclear detonation. This occurs at a rate of 250 detonations per second. This propulsion system is based on the Project Daedalus concept.
36,000 kilometers per second (or about 80 million MPH)
