In the mirror universe, the ISS Havoc (NCC-1866) was an Miranda-class Terran Empire cruiser starship in Imperial Starfleet service in the late 23rd century.
During the reported 2293 rebellion of Captain Hikaru Sulu and the ISS Excelsior, which in actuality was Captain Sulu and USS Excelsior crew from the counterpart universe, the Havoc was dispatched along with the ISS Ruthless to apprehend the Excelsior and its escorts, IKS K'tanco and the IKS Klothos at the K'ath protostar. Both Miranda-class ships were destroyed in the ensuing battle. (TOS video game: Shattered Universe)
