The Tammuz was a Union-class DropShip that arrived on Kore on 11 April 3060. Thought to be a corporate freighter DropShip of the Alfin Corporation who maintained the mining operation on Kore, it turned out to be controlled by Susie Morgraine-Ryan and her pirate band (initially disguised as Clan forces). They occupied the mining settlement in short order to search for a hidden cache of Clan 'Mechs, but a local MechWarrior stumbled across the cache first and used its contents to fight off the pirates. Susie Morgraine-Ryan and the remains of her force left aboard the Tammuz some two weeks later.
Upon landing on Kore the ship was observed to be in a battered state, with its armor dented and pitted from micrometeorites and debris and the paint patched and scuffed.
- name and class confirmed in the epigraph of the book's penultimate chapter; the Tammuz was really a Union and did not use a forged identity
