The Stardeath Howitzer is an Aian weapon designed to completely and irreversibly eliminate even shielded planetary settlements.
The weapon launches a 20,000 tonne block of iron at 0.95c using a combination of an enormous coilgun and massive assistive repulsors. The projectile's kinetic energy is equivalent to 947 teratons of TNT.
Upon impact, the release of energy is sufficient to melt the upper layers of a planetary crust and cause loss of that worlds's oceans and atmosphere.
Only Aian dreadnoughts are large enough to be able to power this weapon.
