The Earthquake Missile is a hefty, Air to Sub-Surface, non-segmented, multi-stage, shockwave effect missile. The Ta'Elans created for the purpose of destroying targets both above and below the ground. It achieves this by burying itself underground, then converting to matter its 7-tonnes' worth of thion particle warhead.
To make its way into the ground without detonating, the Earthquake Missile bores a hole using Roaster Lasers and Plasma Cannons, and keeps the resulting debris away using a force field. Once it is deep enough to detonate, it enters the second stage, in which it floats vertically and sucks the pulverized material displaced on penetration back onto itself. Then, it enters the 3rd stage, detonation.
