Ranger

The USS Ranger (NCC-315) was the prototype of the Ranger-class. It was launched under NX registry in 2215, and shortly there-after changed to NCC.

Only 3 years later in 2218, the Ranger was sent on a First contact mission to Agbar IV. But the mission took a disastrous term, and the Ranger was destroyed by the Klingons. (RPG: Star Trek: Roleplaying Game Starfleet Operations Manual)
