Construction of the aerodrome began in the summer of 1940 after a suitable site was selected on a ridge high above the surrounding coastal plain of the north shore of the Bay of Fundy, east of the town of St. George. Proximity to a Canadian Pacific Railway line running between St. Stephen and Saint John eased the transport of building materials. General contractor Dexter Construction had 200 workers on the project by August 1940 and the runways were finished by November. The base was located southwest of the Camp Utopia, an army training facility for southwestern New Brunswick. The first test flights took place on January 1, 1941 and the base officially opened on July 21 of that year, housing No. 2 Air Navigation School RCAF and later No. 34 Operational Training Unit RCAF, under the command of No. 3 Training Command RCAF, which was headquartered in Montreal as part of the British Commonwealth Air Training Plan. By the end of summer 1941, over 40 buildings were constructed on the base, including 4 large hangars, an observation tower, barracks, drill hall, mess halls and classrooms, along with a water supply and internal telephone system. The three runways were lengthened in the fall of 1941 into the classic BCATP triangle arrangement. The airfield was decommissioned by the RCAF toward the end of World War II, with air force activities in eastern Canada being concentrated at RCAF Station Greenwood, RCAF Station Debert, RCAF Station Summerside and RCAF Station Chatham. The Pennfield Ridge base became the operational location for Heavy Transport until it was purchased several years later and operated by a commercial airline company as an alternative to the inadequate airport serving Saint John at Millidgeville. After the new Saint John Airport was opened in the early 1950s, Pennfield Ridge closed as an operational airfield. One of its runways was used as a drag racing track by the New Brunswick Drag Racing Association during the 1950s-1970s. Today, 2 of the 3 runways are used for drying seaweed which is then marketed as a natural plant fertilizer. The remaining runway is still able to handle small aircraft under visual flight rules conditions; there is a small fuel reserve tank for the use of J.D. Irving Limited and New Brunswick Department of Natural Resources aircraft. Less than to the east of the airfield is the location of the Jim Mollison landing in August 1932, in which Mollison completed the first solo east-to-west transatlantic flight. His aircraft was a de HavillandPuss Moth dubbed "The Heart's Content". On 24 September 2006, a memorial was erected at a nearby park in Pennfield by "The Charlotte County War Memorial Committee" to honour the sixty men who died while on training at Pennfield Ridge. Subsequent research by Pennfield Parish Military Historical Society shows that there were seventy men who died while training at Pennfield Ridge. There were also six civilian casualties as well.
