The Orca class is a ship class of eight steel-hulled Royal Canadian Navy training vessels. Based on the Australian-designed Pacific-class patrol boat, the Orca class was constructed by Victoria Shipyards between November 2004 and November 2008, at a total project cost of C$90.7 million. All are in service at CFB Esquimalt in British Columbia. They replaced the YAG 300 class and operate as training platforms and surveillance craft.

Design and construction

During the early 2000s, MARCOM began searching for a replacement for the 1950s-era wooden-hulled YAG 300 class used to train personnel.[1] Training aboard these outdated vessels while useful became less relevant as MARCOM moved to initial training aboard modern land-based simulators for training officers which more accurately replicated the conditions aboard the Kingston class patrol boats and Halifax class frigate. On 8 November 2004, the Department of National Defence announced a C$69.7 million contract for six new ships, with an option for two more,[1] for a total budget of C$90.7 million.[citation needed]

The Orca class ships are based on the Australian training vessel Seahorse Mercator, itself a derivative of the Australian-designed Pacific class patrol boat.[2] Each ship has a displacement of 210 tonnes, is 33 metres (108 ft) long,[1] has a beam of 8.34 metres (27.4 ft), and a draught of 2.6 metres (8.5 ft).[citation needed] To meet the training requirement, the Orcas are fitted with a larger-than-normal bridge and carry warship-grade navigational equipment.[2]

The Orcas are capable of 20 knots (37 km/h; 23 mph), and have an endurance of 660 nautical miles (1,220 km; 760 mi) at 15 knots (28 km/h; 17 mph).[1][2] Propulsion is provided by two Caterpillar 3516B marine diesel engines, each rated for 2,500 horsepower at 1,600 revolutions per minute.[2]

Orca

Each ship can be operated by a crew of four.[citation needed] Accommodation consists of two two-bunk cabins for the crew (Captain, Executive Officer, Bos'n, Engineer) and four or six-bunk cabins for 20 instructors and trainees[1] for a total of 24 bunks.

The eight vessels were constructed by Victoria Shipyards at Victoria, British Columbia.[2] The first ship in the class, Orca, was laid down in September 2005, launched in August 2006, and delivered to MARCOM in November 2006.[2] Delivery of subsequent vessels was set to occur every three months.[2] The project was completed when the eighth vessel, Moose, was delivered on 27 November 2008.[citation needed] The Orcas are not commissioned into service, so do not carry the HMCS ship prefix; instead, the prefix PCT (Patrol Craft Training) is carried.[citation needed]

Employment

The Orca class vessels are designated as "Patrol Craft Training".[2] The craft are primarily used to facilitate the two-to-six-week long 'at sea' component of naval officer training.[2] Their training capability is also extended to other naval personnel, and the Royal Canadian Sea Cadets.[2] Orcas are vessels of opportunity for surveillance and search and rescue.[2] They are all located at CFB Esquimalt.[citation needed]

Two vessels were temporarily fitted with .50-cal machine guns for port security during Op PODIUM. Op PODIUM was the Canadian Forces' support of the 2010 Vancouver Winter Olympics.[citation needed]
