The KR-TB "Doomtreader" was a freighter produced by Corellian Engineering Corporation. It had expansive cargo holds, heavy deflector shields and dual laser cannons, but came at a relatively high price.
Montross's Hell's Anvil was a modified KR-TB. One of Count Dooku's Dark Acolytes, Tol Skorr, also piloted a KR-TB. Montross's ship had solar ionization cannons that could go through deflector shields.
