ISS Decisive (NCC-74207)

The ISS Decisive was a starship in the Terran Imperial Starfleet under the command of Captain Adriana Faulkner.

History
Following the victory of the Terran Rebellion over the Klingon-Cardassian Alliance, was crowned head of the second Terran Empire. To help secure the Empire's borders against Alliance invasion he commissioned a series of warships based on plans stolen from the prime universe's Federation Starfleet. The first was a trio of fast, powerful battlecruisers:, and ISS Decisive.

The Decisive was launched in 2379 from its construction site at Terok Nor and Adriana Faulkner, an experienced raider captain during the Rebellion years, was assigned to command. For six years she and her crew patrolled the Cardassian border against Alliance incursions, fighting several skirmishes with  forces.

Capture by the Federation
In 2385 the Decisive encountered a spatial anomaly in the, an Alliance ally which had recently surrendered to the Empire. Faulkner and crew found themselves in the prime universe, with their warp drive damaged by the passage. A few hours passed as the damage control teams struggled to repair the warp drive. They were then discovered by the starship USS Susquehanna under Captain Amnell Kree, responding to reports of the anomaly.

Faulkner scrambled the ship to battle stations and fired on the Susquehanna without waiting for hostile actions. Caught off-guard by the unexpected hostility of what had appeared to be a Federation starship at first glance, Kree withdrew briefly, just long enough to assess the situation and deploy her fighters. She then made a warp microjump into Decisive's teeth and let a volley of photon torpedoes loose at point-blank range, battering the shields and causing severe secondary damage. The smaller Akira-class easily outmaneuvered the Decisive, racing to the underside of the ship where only a minimal number of phasers could hit. Kree's fighters attacked, collapsing the starboard shields, and the Susquehanna targeted the larger vessel's starboard nacelle and tore it to pieces with her aft phaser arrays. Kree's helmsman maneuvered the ship into an and another torpedo salvo erupted from the forward launchers, shattering the aft shields and striking Decisive's bridge from behind, killing Adriana Faulkner and most of her command crew instantly.

Faulkner's first officer, Lieutenant Commander Dao Cam Chien, took over as from the battle bridge and tried to get the ship moving into retreat, but Kree and a contingent of MACOs beamed aboard. Kree and one squad headed straight to the battle bridge while the other captured Main Engineering. Dao tried to ambush Kree at the door but the older officer swiftly disarmed him and laid him out in hand-to-hand combat, then gassed the rest of the ship with. She took his combat knife as a trophy and reported the ship's capture to Starfleet Command.
