. In 2007 it was announced that the Canadian Armed Forces would purchase six to eight patrol ships having an ice class of Polar Class 5, meaning that they were capable of limited ice breaking, based on the Norwegian ''Svalbard'' class. This announcement was met with some controversy, and the proposed ships have been called "slush-breakers", by Dr. Gary Stern, a scientist aboard , and

However, it was notable that in 2005 of the nineteen Canadian Coast Guard icebreakers then in service, only six had an ice class higher than Polar Class 5.

would be awarded the $25 billion contract to build six to eight Arctic patrol ships as well as fifteen other warships for the RCN over the next two decades. In September 2014, Prime Minister Stephen Harper announced that the name of the first ship in the class would be ''Harry DeWolf'', named in honour of wartime Canadian naval hero Harry DeWolf, and that the class would be named the ''Harry DeWolf'' class. In December it was found that not enough money had been projected to cover the cost of building the six to eight planned ships and that the budget would need to be increased, delaying the signing of the contract. However, in an effort to drive down costs, Irving Shipbuilding could only project building five ships with the option to build a sixth only if it came under budget. The budget for the project was increased from $3.1 billion to $3.5 billion to ensure a cash buffer. However, by 2018 that approach had been abandoned and the budget for the first six ships had reportedly increased to $4.3 billion. On 13 April 2015 the government announced a second ship would be named ''Margaret Brooke'' in honour of Sub-Lieutenant Margaret Brooke, a Royal Canadian Navy Nursing Sister decorated for heroism for her efforts to save a fellow nursing sister after the sinking of the ferry during

Construction

of ''Harry DeWolf'' was held on 9 June 2016, marking the first naval construction in Canada since 1998, and the largest purposefully-built warship for the RCN in over 50 years. In September 2016, it was announced that construction had begun on ''Margaret Brooke'' and that 50 of 64 modular pieces of ''Harry DeWolf'' had been completed. On 8 December 2017, the three main sections of ''Harry DeWolf'' were fitted into place. The first steel for ''Max Bernays'' was cut on 19 December 2017. Construction of ''William Hall'' started on 3 May 2019. ''Margaret Brooke'' was launched on 10 November 2019. First steel was cut for the fifth ship, ''Frédérick Rolette'', in May 2021 and for sixth ship, ''Robert Hampton Gray'', in August 2022. During the

pandemic, Irving Shipbuilding announced that construction would be halted for at least three weeks beginning in March 2020. ''Harry DeWolf'' was delivered to the Navy in July 2020, and commissioned on June 26, 2021. ''Margaret Brooke'' was delivered on July 15, 2021 and commissioned on October 28, 2022. The two Coast Guard AOPS variants (ships seven and eight) were expected to begin construction in 2022 and 2023.


Potable water contamination

In December 2022, it was discovered that the potable water systems of all the delivered and launched ships had suspected lead contamination from fittings and valves that were manufactured from alloys that exceeded the allowable amount of lead. The ships affected by the contamination were ''Harry DeWolf'', ''Margaret Brooke'', and ''Max Bernays''. ''William Hall'' would be tested for the contamination after the completion of construction.


Criticism

The ''Harry DeWolf'' class has been criticized for its design and effectiveness, as critics believe that the class is ineffective in its designated role of arctic and offshore patrol. Some criticism focuses on the fact that the ships are slow and, compared to the similarly sized Russian

released a report on the proposed AOPS. The report was written by UBC Professor Michael Byers and Stewart Webb. The report's conclusion was that Canada would be better suited to have purpose-built ships, namely icebreakers for the Arctic and offshore patrol vessels for the Pacific and Atlantic coasts. In May 2013, the CBC reported that the cost of the design phase of the project was many times what other countries paid for design, construction, and full-up operational deployment of similar ships. The projected design cost of the AOPS, $288 million, was compared primarily to the Norwegian icebreaking offshore patrol vessel '' Svalbard'' that was designed and built for less than $100 million in 2002, and whose basic design documentation package was purchased by Canada for $5 million. Shipbuilding experts interviewed by CBC estimated that the design cost of the AOPS should have been $10–20 million even if accounting for cost of adapting the Norwegian design to Canadian service. The $288 million design cost was further compared to two European offshore patrol vessel classes that, while significantly cheaper to design and build, have only one third of the AOPS' displacement. Furthermore, the Danish has much lower ice-going capability than the AOPS and the Irish is not ice-capable at all.


Design

The vessels' design was initially intended to incorporate a conventional icebreaking bow for cruising, and would have proceeded backwards for breaking heavy ice. The vessels' stern would have been designed for ice breaking and they would have employed

s for propulsion and for chewing through resistant ice. However, due to cost constraints, a conventional bow-first design was chosen for both light and heavy icebreaking. The propulsion would be provided by diesel-electric twin shafts with bolt-on propellers, similar to existing Canadian Coast Guard icebreakers. The vessels' ice class is Polar Class 5, but the bow region is further strengthened to higher

level. In 2008, a contract was awarded to BMT Fleet Technology and STX Canada Marine to assist in developing technical specifications and a design for the project. The technical specifications were to be used to draft a request for proposals. The government later awarded a design contract to BMT Fleet Technology and STX Canada Marine to develop the design of the vessel for issue to the selected NSPS proponent. The ships are built in three large mega blocks: centre, aft and bow. Each mega block consists of 62 smaller building blocks. The first steel was cut on ''Harry DeWolf'' in September 2015. The ships are designed to displace , making it the largest class of naval vessels produced in Canada in the past 50 years with the previous being the retired . They are capable of outfitting multiple payload options such as shipping containers, underwater survey equipment, or a landing craft. The vessels have a crane to self-load/unload, and a vehicle bay to carry vehicles for deployment over the ice. The design also calls for an enclosed cable deck and

to better cope with the Arctic environment. On the open sea, the ship has fin stabilizers to reduce roll that are retractable during ice operations.


Armament and aircraft

In August 2015, BAE Systems won the contract to provide up to six modified Mk 38 Mod 2 25 mm cannon for the naval ships in the class (the coast guard ships will be unarmed, as CCG has no enforcement mandate). This contract also covers the service life of the weapons. The vessels have a hangar and flight deck capable of employing and maintaining the same maritime helicopters as the RCN's other vessels: the CH-148 Cyclone and the CH-149 Cormorant.


Bridge and navigation system

In 2014 OSI Maritime Systems Ltd. was selected by Lockheed Martin Canada to design the integrated bridge and navigation system for the AOPS program, this was followed by a contract for the Implementation Phase in 2015. Since, OSI has built and installed all AOPS Integrated Bridge and Navigation ship sets.

requirements. Some areas are to be changed to meet the needs of coast guard equipment and there will be modifications to the deck. Despite the supposedly limited modifications, the cost of the two Coast Guard variants was reported in 2022 as likely to be significantly higher than that of the naval variants.

Possible additional roles

As the ''Harry Dewolf''-class ships started to enter service, comments appeared in Canadian professional military journals suggesting that they might be useful as small amphibious ships carrying up to 50 to 60 soldiers/marine infantry into the Arctic. and
