Star Trek Expanded Universe

Paladin was the name of the captain's yacht attached to the USS Scandalon in the late 24th century.

In 2376, Captain Stephen Tecklenberg took the Paladin to rendezvous with Dr. Bill Hoesch in the Letchworth Nebula. The Orions captured Tecklenberg, and though Starfleet investigated, the Paladin was declared missing in action after six weeks. (Star Trek: Pendragon)
