CNAV Endeavour

CNAV Endeavour (later CFAV Endeavour, after the 1968 unification of the Canadian Armed Forces) was an Endeavour-class research ship. The vessel served the Royal Canadian Navy and later the Canadian Forces from 1965 to 1999. Endeavour performed research in oceanography and anti-submarine warfare, primarily on the West Coast of Canada.

Description
Endeavour had a displacement of 1560 LT at full load with a length overall of 236 ft, a beam of 38 ft and a draught of 13 ft. Endeavour's hull was stiffened for work in areas with ice.

The ship was propelled by two shafts driven by a diesel-electric engine creating 2,960 shp. The machinery space was insulated to reduce noise. This gave the vessel a maximum speed of 16 kn and a range of 10000 nmi at 12 kn. Endeavour could turn 2$1/2$ times its length. The ship had a 48 x helicopter deck. The ship was fitted with two 9-ton Austin-Weston telescopic cranes. Two oceanographical winches, each holding 5000 fathom of wire, two bathythermograph winches and one deep-sea coring winch were also fitted. The vessel had a complement of 50, which included 10 officers, 13 scientists and two aircrew.

Service history
Endeavour was ordered from Yarrows Ltd. and constructed at their shipyard in Esquimalt, British Columbia and given the yard number 250. Endeavour's keel was laid down on 4 September 1963 and the ship was launched on 4 September 1964. The vessel was commissioned into the Royal Canadian Navy on 9 March 1965 and given the hull number AGOR 171. Endeavour was deployed on the West Coast of Canada researching anti-submarine warfare from the time the ship entered service until 1999. The vessel replaced the old Bangor-class minesweeper HMCS Oshawa (J330). In 1999, Endeavour was transferred to the East Coast to replace CFAV Quest temporarily, while Quest was undergoing modernisation. In 2000, Endeavour was discarded.
