The first starship Enterprise was a Constitution class vehicle commissioned in 2245 at StarfleetÕs San Francisco Yards, orbiting Earth. This ship, first commanded by Captain Robert April, then by Captain Christopher Pike and Captain James Kirk, became a historic figure in StarfleetÕs early exploration of deep space. This ship was refitted several times, remaining in active service until 2284 when it was assigned to training duty at Starfleet Academy. It was destroyed in 2285 while defending the Mutara sector against a Klingon incursion. Æ
