Aircraft carried:

HMCS Skeena was a St. Laurent-class destroyer that served in the Royal Canadian Navy and later the Canadian Forces from 1957-1993.

Skeena was laid down by Burrard Yarrows at Vancouver on 1 June 1951. The vessel was launched on 19 August 1952 and commissioned into the Royal Canadian Navy on 30 March 1957, initially carrying the pennant number DDE 207, as a destroyer escort.

Design

The St. Laurent class were built to an operational requirement much like that which produced the British Type 12, and powered by the same machinery plant. The rounded deck-edge forward was adopted to prevent ice forming.[7] The vessels were designed to operate in harsh Canadian conditions. They were built to counter nuclear, biological and chemical attack conditions, which lead to a design with a rounded hull, a continuous main deck, and the addition of a pre-wetting system to wash away contaminants. The living spaces on the ship were part of a "citadel" which could be sealed off from contamination for the crew safety. The ships were sometimes referred to as "Cadillacs" for their relatively luxurious crew compartments; these were also the first Canadian warships to have a bunk for every crew member since previous warship designs had used hammocks.

Armament

As a St. Laurent-class destroyer escort, Skeena was fitted with twin 3 inch/L50 guns for engaging both surface and air targets. Her anti-submarine armament consisted of a pair of triple barrelled Limbo ASW mortars in a stern well. The stern well had a roller top to close it off from following seas. The design included provision for long-range homing torpedoes, in this case BIDDER [Mk 20E] or the US Mark 35. They were never fitted however.[7]

As built, the twin 3-inch 50-calibre anti-aircraft mounts were installed without shields. These were added in 1963. The gun housings are fibreglass. [note 1]

Machinery

The vessels of the St. Laurent class had two Babcock & Wilcox water tube boilers installed[8] providing 600 PSI (4.1 MPa, 42 kgf/cm²) at 850 °F (454.4 °C).[4]

The steam produced by these boilers was directed at two geared steam turbines which powered two shafts, providing 30,000 HP (22 MW) to drive the ship at a maximum speed of 28.5 knots (52.8 km/h).[9] By the early 1990s, the quoted maximum speed was only 27 kt.[4]

The propelling machinery was of British design. Canadian Vickers supplied the machinery which was manufactured in Canada. The main turbines and machinery were of English Electric design.[9]

Service history

HMCS Skeena commissioning, 1957

After commissioning, Skeena was assigned to the Second Canadian Escort Squadron.[10] On 29 January 1962, Skeena accidentally shelled an American village in the Strait of Juan de Fuca . As one of four ships practicing their gunnery, some of the shrapnel from the ship's guns fell on Clallam Bay, Washington. The commander of the warship, Richard H. Leir, faced a court-martial for the event.[11] He was later convicted.[12]

Skeena underwent conversion to a destroyer helicopter escort (DDH) beginning in 1964 at Davie Shipbuilding. The vessel exited the yard and was recommissioned as a DDH with pennant number DDH 207 on 14 August 1965.[13]

For this conversion Skeena was fitted with helicopter platforms and SQS 504 Variable Depth Sonar (VDS). When ships were fitted with the helicopter platform, the single funnel was altered to twin stepped funnels to permit the forward extension of the helicopter hangar.[14] Stabilizing systems were added to allow for helicopter recovery in any sea conditions, and a single CH-124 Sea King was carried.[8] To make room for the helicopter deck, the aft 3 in (76 mm) mount and one of the Limbos were removed.[8] The ship was sent to Halifax, Nova Scotia to work with the east coast fleet.[13] She was assigned to Third Canadian Escort Squadron.[15]

In 1972, Skeena was designated a French Language Unit (FLU). A French Language Unit was a Canadian Forces designation where French was to be the primarily spoken language to encourage career opportunities for Canadian Francophones. During the 1976 Summer Olympics which were held in Montreal, Quebec, the vessel was among those assigned to provide security.[13]

Skeena was selected by the Canadian Forces for the Destroyer Life Extension (DELEX) program and completed this refit on 20 November 1981. During the summer of 1991, the ship participated in the NATO exercise Ocean Safari 91. She was paid off from active service in the Canadian Forces on 1 November 1993.[13]

Skeena was sold in 1994 and scrapped in India in 1996.[13]
