HMCS Edmonton (MM 703) is a Kingston-class coastal defence vessel that has served in the Canadian Forces since 1997.

Edmonton is the fourth ship of its class, all of which were built for the Maritime Coastal Defence Vessel Project. It is the first vessel to use the designation HMCS Edmonton.[1]

Edmonton was laid down on 8 August 1995 at Halifax Shipyards Ltd., Halifax, and was launched on 31 October 1996. It was officially commissioned into the CF on 21 May 1997 and carries the pennant number 703.

It is assigned to Maritime Forces Pacific (MARPAC) and is homeported at CFB Esquimalt.

Design and Construction[edit]

The Kingston-class coastal defence vessel was conceived to use commercial off-the-shelf (COTS) equipment and construction techniques in a ship designed to military specifications. The construction of the design required the building of partially outfitted steel block units, which were assembled into larger blocks and those blocks were integrated into the ship. The decks were assembled upside down with pre-outfitting of the underside of the deck prior to installation on the ship. The ship is outfitted with a degaussing system from Power Magnetics and Electronic Systems.[2]

Kingston class vessels are designed to carry up to three 6.1-metre (20 ft) ISO containers with power hookups on the open deck aft in order to embark mission-specific payloads.[3]

Armament and Sensors[edit]

Kingston-class vessels are outfitted with a Bofors 40 mm 60 mk5C rapid fire gun, and two 12.7mm machine guns. The ships are equipped with one of three modular mine countermeasures systems: the deep sea Thales MMS mechanical mine sweeping system, the route survey system or the Sutec remotely operated vehicle (ROV) mine inspection system.[2]

The navigation equipment installed in Kingston-class vessels are a Kelvin Hughes I-band navigation radar and a global positioning system. The surface search radar is the E to F-band Kelvin Hughes 6000.[2]

Propulsion[edit]

The ship is equipped with four main Wärtsilä UD 23V12 diesel engines which are coupled to four alternators (600 V AC). Two Jeumont electric motors (±740 V DC) provide power to the two LIPS Z-drive azimuth thrusters which are fitted with fixed-pitch reversing propellers. The propulsion system provides 15 knots (28 km/h) maximum continuous speed. The range at the economical cruising speed of 9 knots (17 km/h) using two engines is 5,000 nautical miles (9,000 km) with a 20% margin in tank capacity. Mechanical minesweeping is carried out at 8 knots (15 km/h). The crash stop length is five ship lengths from a speed of 15 knots (28 km/h).[2]
