The River-class destroyer is Canada's future guided-missile destroyer class, a 15-ship Royal Canadian Navy program based on BAE Systems' Type 26 Global Combat Ship and built through Irving Shipbuilding with Lockheed Martin Canada as design lead. Current official fact sheets describe a SPY-7/Aegis combat-system architecture, a 24-cell Mk 41 vertical launch battery for SM-2, ESSM, and Tomahawk missiles, Naval Strike Missile, Rolling Airframe Missile, Mk 54 torpedoes, and a CH-148 Cyclone aviation facility.

Combat-System Architecture

The River-class design concentrates air defence, land-attack, anti-ship, anti-submarine, and aviation functions in one large surface combatant rather than splitting them across separate destroyer and frigate classes.

LayerDocumented equipmentRole in the ship
Air and missile defenceSPY-7 radar, Aegis Combat System with Canadian Tactical Interface, Cooperative Engagement Capability, SM-2, ESSM, and Rolling Airframe MissileProvides long-range surveillance, sensor networking, area air defence, point defence, and close-in defence.
Strike and surface warfareTomahawk, Naval Strike Missile, BAE 127 mm gun, and two stabilized 30 mm gunsGives the class land-attack, anti-ship, naval fires, and close surface-engagement options.

Its public record is strongest as a fleet air-defense, escort, surface-strike, and undersea-warfare platform: the class combines AN/SPY-1D(V), Aegis Baseline 7.1, SM-2, ESSM, Harpoon, helicopter facilities, torpedoes, and a 48-cell Mk 41 vertical launch system, with later Australian test firings adding Naval Strike Missile, SM-6, and Tomahawk integration context.

BAE Systems and Royal Navy sources distinguish the early Batch 1 ships from the larger Batch 2 vessels, whose 90 metre hull, 30 mm gun, Merlin-capable flight deck, and rotating forward-deployed crews make them useful for Caribbean, South Atlantic, Mediterranean, West African, and Indo-Pacific tasks. HMS Trent gives the class a specific documented crisis role through its 2023-2024 deployment to Guyana during the Guyana-Venezuela Essequibo crisis.

Public Canadian sources describe it as the central software layer that integrates ship sensors, weapons, communications, and information sources for situational awareness and combat-system coordination, with current users or planned integrations including Canada, New Zealand, Chile, and Germany.
