Kinetic energy weapons provide the biggest punch of any spacecraft weapons short of nukes; their range is, however, very short. Kinetic energy weapons are magnetic quadrupole accelerators used to fire flechette canisters. A kinetic weapon requires a power storage system.
Δxa = a R2 / v2
P(hit) = r2 / (Δxa)2
Firing rates of 1 shot per second are achievable with current KE weapons. Maximum mass per projectile is approximately 5 kg. Acceleration of projectile is approximately 100 000 g, giving a weapon length of 300 m.
The probability of a hit can be improved by using rocket-powered projectiles for terminal guidance.
