Warsong
From Tardis Wiki, the free Doctor Who reference
The Warsong was a Sontaran world engine weapon. It was created during the Fifty-first Star Fall Campaign to counteract the heavy losses they were taking from the Rutan Host. However, the weapon was unable to be deployed. The mortally wounded Surnat Gaq took the Warsong to Earth, where it lay dormant until World War II. (COMIC: The Instruments of War)
