UNSC Thatcher is a ship in service with the UNSC Navy.
Before UNSC Port Stanley and her crew departed for Cascade on shore leave in 2553, Kilo-Five was deployed to retrieve a shipment of armaments from Thatcher. They were to be delivered to Avu Med 'Telcam, leader of the Servants of the Abiding Truth.
The ship may be named for Margaret Thatcher, the former Prime Minister of the United Kingdom from 1979 to 1990.
