ISS Indomitable
From Star Trek : Freedom's Wiki
In the Mirror Universe, the ISS Indomitable was a Constitution Class Imperial Starfleet vessel in service in the 23rd century. It was destroyed by Klingons in 2248 while under the command of Captain Thorpe. The Indomitable had been assigned to destroy a new weapon under development by the Klingon Empire. The mission was later completed by the ISS Constellation commander by Commodore Robert April.
