Irving's Halifax shipyard builds ice-capable patrol vessels through modular construction, outfitting, integration and trials. DND records delivery of all six naval AOPS by August 2025. Two additional Coast Guard variants have a different mission-system fit and remain a separate construction and acceptance programme; naval deliveries do not establish their completion.

Readiness
A technology readiness level is not established by the reviewed public sources.
Ice-capable patrol ships provide a platform for northern presence and surveillance, while actual awareness outcomes depend on embarked sensors, missions, and operational tasking.
Arctic and Offshore Patrol Ship construction may help teams working on Future submarine operational capability by contributing to maritime and undersea operations, Arctic and northern operations, and detection and situational awareness.
Arctic and Offshore Patrol Ship construction may help teams working on Persistent uncrewed underwater surveillance by contributing to maritime and undersea operations, Arctic and northern operations, and detection and situational awareness.
Arctic and Offshore Patrol Ship construction may help teams working on Dual-use northern infrastructure and partnerships by contributing to Arctic and northern operations and advanced materials and manufacturing.

The cited official portfolio material supports the Arctic and Offshore Patrol Ship construction capability family and its described delivery scope; product and platform availability remains configuration-dependent.
Supports: Defence need · Persistent uncrewed underwater surveillance
The official requirement calls for long-duration uncrewed vehicles that deploy and employ sensors to provide persistent coverage, with initial delivery anticipated in 2035/2036.
Supports: Defence need · Persistent uncrewed underwater surveillance
The project requires persistent sensor coverage in strategic northern, coastal and expeditionary areas and identifies sonar and acoustic systems among the relevant investment capabilities.
Supports: Defence need · Dual-use northern infrastructure and partnerships
The program describes collaboration with governments, Indigenous partners, communities, academia, industry, and allies, plus roads, runways, seaports, medical capacity, power generation, employment, training, and procurement benefits where feasible.
Supports: Defence need · Dual-use northern infrastructure and partnerships
The strategy states that northern infrastructure is stretched and insufficient for the scale and complexity of military, industrial, and civilian activity and requires climate-resilient, strategically located, dual-use investment.
