Greenwood was a small hamlet south of the Dominion Atlantic Railway's Kingston Station. In 1942, the Royal Air Force created the RAF Station Greenwood and built an aerodrome on nearby farmland for a facility to train aircrew under the British Commonwealth Air Training Plan. The Royal Canadian Air Force took over the facility in 1944. It was renamed RCAF Station Greenwood, a name it kept until the February 1, 1968 unification of the Canadian Forces. Then the airfield and related facilities were renamed CFB Greenwood.
