USS Phoenix

The USS Phoenix was a Federation Starship assigned to patrol the border between the Federation and the territories of one of its former enemies, the Klingons. The captain of the ship was a veteran of the Human-Klingon War and decided one day that he wanted revenge for the attacks by the Klingons on his home planet. He destroyed dozens of Klingon transport vessels after going rogue the ship was eventually found by the USS Enterprise.

The captain tried to explain to Jean-Luc Picard that 'the war was still going on' and that 'no-where was safe', but Picard simply decided to arrest him. However, the Phoenix instead drove into Klingon space and threatened to destroy one of their outposts. Eventually, one of Jean-Luc's technicians beamed aboard the Phoenix and sang the captain a song to calm him down. The ship was then returned to the Federation intact, and the peace between the Federation and the Klingons was kept.

After this event, the USS Phoenix never saw service again as it had adopted the nickname the USS Phailure. No captain would take the Phoenix as his ship because of this and it was eventually disassembled to be used to repair other ships. What a failure.
