Pagh is the name of a Klingon starship. It was a prototype K'Tinga-class bird-of-prey ship developed by the Klingon Empire, which had the capability to fire while cloaked.
General Chang betrayed the Empire and Chancellor Azetbur by attempting to sabotage the Khitomer Conference, held in 2293. However, the USS Enterprise destroyed the ship before it could attack the conference.
