An Excelsior-class Federation starship that was first to answer the distress call from Khitomer in 2346, where its officer Sergey Rozhenko found and adopted the young Worf.
This USS Intrepid was an Excelsior-class starship in service in the 2340s, distinct from the Constitution-class ship destroyed in 2268 and from the later Intrepid class.
It was the nearest vessel when the Klingon outpost on Khitomer came under Romulan attack in 2346. Its crew found almost no one alive. Chief Petty Officer Sergey Rozhenko, a warp field specialist, discovered a six-year-old Klingon boy in the rubble and, with no relatives known, took him home to Gault to raise with his wife Helena.
The ship's part in the rescue is recounted in Sins of the Father, where its sensor records of the attack become evidence in the Klingon High Council's case against Worf's father, and again in Family.
