The USS Tian An Men (NCC-21382) was a Miranda-class Federation starship in service during the latter half of the 24th century. The Tian An Men was Ben Bartholomew's first assignment out of Starfleet Academy in 2362. (Star Trek: Pendragon: "Children of the Burning Heart") The Tian An Men went into spacedock at Starbase 234 for major repairs in early 2368. Before those repairs were complete, she was deployed as part of Captain Jean-Luc Picard's blockade of the Klingon-Romulan border during the Klingon Civil War, and was one of the ships creating the Tachyon detection grid.
