Penk's starship was a starship operated in the Delta Quadrant, by an individual named Penk, during the late 24th century. The starship was used as a main base of Tsunkatse matches, which took place on the ship but were transmitted live to millions of viewers over the sector. Heavily armed, this vessel was five million metric tons, had reinforced hull plating protected by covariant shielding (which prevented sensor penetration), and was armed with neutronic weaponry.
In 2376, after Seven of Nine and Lieutenant Commander Tuvok were kidnapped by Penk, the USS Voyager attacked Penk's ship, albeit with little success. Fortunately, the Delta Flyer arrived and disabled the vessel's signal generators and transmitters, allowing for the two crewmembers to be beamed back to Voyager. (VOY: "Tsunkatse")
