T'Ong, I.K.S.

An old, K't'inga-class Klingon battle cruiser, whose crew -- from over 75 years ago -- awakened from cryogenic sleep, circa stardate 42901.

Unaware that the Federation and Klingons were now allies, they awoke ready to begin there left off, ready to pillage undefended Federation outposts. K'Ehleyr, the Klingon emissary, and Worf, helped subdue the T'Ong's crew without bloodshed.
