Piasecki Hup-3

Piasecki HUP-3In mid-1954 a number of ex-US Army Piasecki HUP-3's were taken on strength at HMCS Shearwater. The HUP-3's, flown by Helicopter Utility Squadron 21 (HU 21) were intended primarily for use aboard the ice breaker HMCS Labrador to provide a heavy (900 pound - 408 kg) lift capability. HUP-3's were embarked on HMCS Labrador during arctic cruises from 1955 to 1957 and were used to site radar navigation beacons for oceanographic and hydrographic surveys and participate in marine biology, ice physics and Defence Research Board activities. During the 1957 cruise Labrador's HUP was used to assist the RCAF to fly equipment into remote Mid-Canada line radar sites which were under construction. When not embarked on the ice breaker the HUP's were used for search and rescue and general naval utility as well as providing support to other government departments.
