Since the Red Cliff radar station was to be a part of the North East Air Command (NEAC) this unit was financed by the Americans and the station was originally manned by the 108th AC&W Squadron which arrived in Pepperrell AFB in August 1952. Red Cliff was intended to serve as an Air Defence Direction Centre (ADDC). The 108th installed the initial radar equipment the AN/CPS-5 Search radar and the AN/TPS-1D Height Finder radar. The 108th was re-designated as the 642nd AC&W Squadron on August 1st 1953 and the 642nd became operational in June, 1954 making use of the CPS-6B search radar at that time.
As was the case with other Pinetree Line radar stations in Newfoundland and Labrador, the station was supposed to be a self-contained, self-supporting unit that would operate on a continuous basis. The station was somewhat limited to its acreage since it was located on top of a hill. Because of its open location and the proximity to water, the station was subject to severe winds, snow accumulations and extremely low temperatures. The structures included barracks, shops, warehouses, dining halls, recreational areas as well as the operations centre.
Radar operators in the AC&W Squadron tracked the movements of aircraft sighted and passed speed, height and direction information to a Direction Centre (DC) and fighter interceptor squadrons. Fighter aircraft could be airborne in minutes after an alarm was given, and they closed in on unidentified planes by means of direction provided by the radar operators. Another of the Red Cliff functions was furnishing navigational aid to friendly aircraft operating in the area. Their detection of May-Day calls contributed to quick search and rescue efforts.
It was subsequently determined that there was inadequate radar coverage between Red Cliff and St. Anthony. To increase low altitude coverage, and to provide some degree of back-up to the main Pinetree Line radar stations, approval was obtained in 1955 for the construction of some small light-weight radar stations making use of the AN/FPS-14 radar equipment. These smaller AC&W units were to be known as gap fillers. A gap filler, reporting to Red Cliff, was constructed at Elliston Ridge (Bonavista Bay). This unit was known as Det. #1 642 AC&W Squadron and was identified as site number N-22B. This unit became operational at the end of April 1957 and it was closed in 1960. The gap filler at Elliston Ridge was somewhat larger than other gap fillers since its mission included additional functions.
The Red Cliff AC&W operation was similar to other sites except that more functional responsibility was given to the station because of its close proximity to the NEAC (and, in 1960, the 64th Air Division) headquarters at Pepperrell AFB. At the time that Red Cliff was phased out in October 1961 there were 140 military and 106 civilians at this location.
When the Red Cliff AC&W station closed, the US Navy at Argentia reconstructed and equipped one large building as an unmanned Radio Communications Centre. While this was an elaborate operation, its usefulness was short lived when more sophisticated radio equipment came into use with long-range capabilities.
Apart from the specialized radar and radio equipment, all the assets, including the buildings and their contents, were turned over to Crown Assets for disposal. Only shells of buildings remain at Red Cliff.
NOTE:
You are encouraged to look at the two dozen photos which were taken in May 1998. I am somewhat surprised at the condition of some of the bunkers.
