The Glen class tug is a class of naval tugboat operated by the Royal Canadian Navy.[1]


The five vessels are divided between the two fleets of the Royal Canadian Navy, with three assigned to Maritime Forces Atlantic and two assigned to Maritime Forces Pacific.[2][3]

Maritime Forces Pacific, CFB Esquimalt
Maritime Forces Atlantic, CFB Halifax

Other tugs[edit]

The Canadian Forces operates six other smaller tugboats, the 140-ton CFAV Tillicum, and five 45-ton Ville class tugs.[4] The smaller tugs are also split between both coasts.

While the Glen class tugs are equipped for firefighting, the Canadian Forces maintains a pair of dedicated Fire-class fireboats, the 140-ton Firebrand (YTR 562) and the Firebird (YTR 561), one each in each port.[5] The crews of the fireboats are cross-trained and able to crew a Glen class vessel in emergencies.

The Royal Canadian Navy operated a fleet of tugboats during the Second World War which were also named the Glen class.[3] The vessels of the current Glen class are each named after one of the vessels of the earlier class. The vessels of the earlier class were sold off into civilian service, with the Glenevis still in civilian service as late as 2007, and the Glencove still currently operating on the Pacific Coast as the Glen Rover.

On December 4, 2012 the Department of National Defence published an enquiry for Canadian shipbuilders interested in building replacements for the Glen class tugs¸ and Fire-class fireboats.[6][7] A single class would replace both the tugs and the fireboats, and would be operated by civilian crews. The replacement vessels would have water cannons that could be controlled remotely, by a single individual. The replacement vessels would have bollard pull of 40 tons. The replacement vessels would be limited to 33 metres or less, and limited to a draft of 6 metres or less. Since their intended role would be harbour duties, they would have limited range and crew berthing capacity.

Note that the Naval Large Tug Construction Project is not part of the National Shipbuilding Procurement Strategy. Under Section 10 of the NSPS Umbrella Agreement, ships displacing less than 1,000 tonnes must go to competition outside NSPS-contracted shipyards. That was meant to spread the Federal spending among the smaller yards. That sounds good but DND wants all six Naval Large Tugs to be built by a single yard. So much for spreading it around.
