War in Heaven Tech Room Description

The Federation's Mercury-orbit antimatter manufacturing stations have been active for decades. The result is a formidable stockpile of antimatter for use in heavy anti-warship torpedoes. These weapons were designed before the beginning of the recent civil war, but never manufactured in bulk due to ethical concerns. The GES-21 Jackhammer is comparable to the GTVA's Cyclops warhead in terms of its intended tactical role, but it can be mounted even on Uriel gunships for organic anti-warship strikes.
