X-29

X-29 was a Earth battle cruiser whose high ranking officer was an unnamed captain. The cruiser captain apprehended the Earth police ship 2390, which had earlier been stolen by the Master. The captain then captured the Draconian prince and the Third Doctor, who were on board, and refused the Doctor's request to go after the Master (who was fleeing in a different vessel). The captain then took the Doctor and the prince to Earth to let Earth security deal with them. (TV: Frontier in Space)
