Cyber-Warship (Bad Day in Tinseltown)
From Tardis Wiki, the free Doctor Who reference
A Cyber-Warship experimented with a dimensional phase weapon and was put out of phase with reality and imbedded in a frontier planet on the Outer Rim of the Mutter's Spiral. When Polly Juno attempted to hijack it for her new army, the warship was destroyed, creating a wormhole. (AUDIO: Bad Day in Tinseltown)
