Interstellar Kinetic Kill Vehicles, (AKA “Planetbusters”) are a kind of high-speed projectile that was made to destroy planets.

They are house-sized bullets of depleted uranium, built up over years of waste on several UAN homeworlds. The bullets themselves are exceptionally expensive to produce and lift, and are propelled by multi-kilometer-long cannon-ships to half the speed of light. Some are even equipped with FTL drives, specifically to make them impossible to detect until it is too late.

To date, seven planets have been rendered completely uninhabitable, two of which were done via Planetbuster.
