In 1946, No. 12 Groups underground bunker at nearby RAF Watnall was vacated and upgraded as part of the ROTOR radar network to track any threats from the Soviet Air Force, it remained in this capacity until 1961 when it was closed but left in a state of readiness. Some personnel were accommodated at Hucknall with the airfield supporting visits by ROTOR associated communications flight aircraft. In February 2014, the bunker was profiled on Channel 4's "The Restoration Man" when it was undergoing conversion into a 1940s-themed guesthouse, incorporating many of the original design features.
