USS Yorktown (NCC-61137)

The USS Yorktown (NCC-61137) was a Federation starship that was in service during the late 24th century.

In 2369, while under the mind control of interrogators on the planet Tilonus IV, Commander William Riker believed that he met a woman named "Commander Bloom," who was first officer of the Yorktown, at the Tilonus Institute for Mental Disorders. 

The Yorktown traveled from Theta Omicron IV to visit starbase Deep Space 9 on stardate 47550.1, while under the command of Captain H. Zimmerman. 

In a the anti-time future created by Q, the Yorktown'' was assigned near the border with the Klingon Empire in 2395. Admiral William T. Riker informed retired Ambassador Jean-Luc Picard that he would have the Yorktown run some long-range scans in the Devron system. ''

In 2374, the Yorktown was one of many Federation starships that were assigned to defend the Setlik system from Dominion invasion. When the Dominion finally invaded the system later that year, the Federation were able to hold the system, but lost seven ships, including the Yorktown.

Despite the Starfleet victory in holding the system, Christopher Mackenzie would still blame himself for the loss of over 5,000 lives, as it was he who planned the defense of the system, in his capacity as a tactical advisor for Starfleet Command. (: "The Curse of the Warrior")

A Yorktown was launched as a replacement in 2376, bearing the registry NCC-90276. (Decipher Games: Starships)
