The USS T'Plana-Hath (NCC-1004) was an Engle-class Federation starship operated by Starfleet during the mid-23rd century.
In 2256, the T'Plana-Hath was among the starships that arrived at a binary star system to reinforce the USS Shenzhou against a Klingon force. In the ensuing battle, it came under heavy attack from three Klingon warships, but was relieved by the Shenzhou. (DIS: "Battle at the Binary Stars")
An illuminated memorial to the T'Plana-Hath was displayed in the mess hall aboard the USS Discovery after the battle. (DIS: "Lethe")
