USS Defiant (NCC-1764)



The USS Defiant (NCC-1764) was a Federation Constitution-class (Bonhomme Richard sub-type) heavy cruiser in service to Starfleet in the 23rd century. She was the last of the original 13 Constitution-class starships to be commissioned.

Construction and Service History
Construction began on the Defiant at Tranquility Base, Luna, in the 2250s. During the early years of her service, the Defiant conducted many missions of importance for Starfleet, and constantly patrolled the Klingon Neutral Zone as tensions between the two powers continued to rise. During that time, the Defiant became the sixth Federation starship to encounter the N'shaii, and was easily able to dispatch them.

During the Four Years War, the Defiant and a squadron of Baton Rouge-class cruisers, under the command of Commodore Jarv Maxwill, were escorting convoy Y-16Z to Deuteronomy 3 and passed by the Rebonet system. They were ambushed by a small task force of Klingon cruisers and gunboats in what became known as the Attack of Convoy Y-16Z. All eight Klingons ships were either destroyed or captured during the battle.

At sometime prior to 2265, the Defiant was refitted with new technologies, as well as receiving some cosmetic changes to the look of the ship. The USS Constellation and USS Enterprise were two other vessels that received the same treatment.

In late 2265, the Defiant returned from her first five-year mission, and Captain Serling stepped down as commanding officer. He was replaced by Captain Thomas Blair who took the Defiant out on her second five-year mission in early 2266. With increasing tensions with the Klingons, the Defiant was once again posted along the Neutral Zone.

By 2267, the Defiant had been assigned to operations in the Taurus Reach. That year, it accompanied the USS Endeavour and the USS Akhiel on a mission to drive Klingon forces off of Golmira, a low-tech planet where a Shedai conduit had been discovered.

In 2268, the Defiant was called to the Klingon colony on Traelus II after receiving a distress call. A landing party discovered no Klingon survivors left on the colony, but they recover a land-based web generator of Tholian origin. The Defiant set a course back for Federation space, but soon found themselves being pursued by three Tholian vessels. Trying to escape the Tholians, the Defiant entered a spatial interphase and became trapped. Captain Blair managed to get a distress call out to the USS Enterprise before the crew succumbed to madness and started to kill each other.

By the time the Enterprise arrived at the Defiant's location, three weeks later, the crew of the Defiant were dead, and the ship had been drawn deeper into the interphase. Interference from the Tholians stopped the Enterprise trying to retrieve the Defiant and she was left behind.
