The CFS Carp Richardson Detachment was a military operated radio communications transmitter station linked by landline to CFS Carp located off Lanark County Road 10 East of Perth, Ontario. The detachment was built with a hardened two story underground bunker built to accommodate the Signals personnel needed to operate the transmitter in case of war, as well as a mess hall, sleeping quarters, offices, decontamination facilities, and its own power generation facilities. Its location was chosen to be far enough away from CFS Carp to ensure survivability in the case of a nuclear strike against CFS Carp, and to reduce the risk of interference from its twenty powerful radio transmitters.
