The USS Enterprise (NCC-1701) was a heavy Constitution-class crusier in service in the later half of the 23rd century. In the course of her career, she became the most celebrated Starfleet vessel of the period. The Enteprise achieved her lasting fame during the command of Captain James T. Kirk (2265-2270). In her fifty years of service and discovery, through upgrades and three refits, she took part in numerous military engagements, first contacts, and time travels. The Enterprise was honorably decommissioned in 2295.
