    It doesn’t really matter what kind of engine it is if it’s going fast enough.

    Anything with enough mass and acceleration to move a human being from planet to planet in a reasonable timeframe has the kinetic energy required to wipe out a city. Once you start reaching relativistic speeds, you can take out entire planets by simply not slowing down on approach.

      Although you are correct, this destroys the engine.

      A good, efficient fusion engine just needs to point the exhaust end towards the enemy and the hyper-accelerated particles will punch a hole through the target for you. And then you point at the next target, etc. etc.

      Also, it’s a butchered quote from Larry Niven’s Known Space books, referred to as the “Kzinti Lesson” - because the Kzinti thought humanity was unarmed and helpless until they discovered that humans are really good at improvising weapons.
