As at November 3072 the JumpShip Cancer was serving as the CSA Cancer within Clan Star Adder and was part of a group of three JumpShips acting as attendent vessels to the Volga-class transport CSA Pompeii. The four vessels were tasked with travelling to the Tanis system as part of a routine roulemont of the Star Adder garrison in the system. Star Admiral Humphrey Truscott, the commanding officer of the Pompeii, was stunned to discover on arrival that the Tanis system was no longer under the control of either the Star Adders or their allies, Clan Cloud Cobra; instead, the nadir jump point was guarded by three Carrier-class DropShips and a significant AeroSpace Fighter force bearing the colors of Clan Burrock. Admiral Truscott immediately ordered the Cancer to jump out and relay the information back to the Clan; even as the Cancer jumped, the Adder forces came under attack, with both of the other JumpShips destroyed even as they were launching their DropShips. The resulting engagement was brutal, with just one Carrier and a handful of fighters left active after the battle; the Pompeii managed to escape from the Tanis system by hot-charging her jump drive, but the emergency jump inflicted catastrophic damage on the K-F Drive and the result was a fatal misjump. The mangled, twisted wreckage of the Pompeii appeared from hyperspace at her destination some eight months after initiating the fatal jump from Tanis.
