Irving Shipbuilding integrates large naval programmes through Halifax shipyard production, supplier coordination, outfitting and phased testing. River-class construction combines Irving's prime role, Lockheed Martin Canada's design team and separately sourced ship systems. DESMI's June 2026 pump and hot-water package announcement illustrates the supplier integration needed for the first three ships.
Technical detail
Core features
Prime shipyard production and supplier coordination
Integration of design-team and ship-system packages
Progressive construction, testing and delivery management
Program Management
Supply Chain
Systems Integration
Use & integration
Recorded applications
National fleet recapitalization
Industrial mobilization
Complex platform delivery
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Six naval AOPS have been delivered, while the first River-class ships are in production. Experience on one class does not establish completion of another.
Commercial availability
Capacity is committed through multi-year government shipbuilding programmes and supplier packages.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
Complex naval program integration may help teams working on Canadian submarine sustainment and industrial capacity by contributing to logistics and sustainment and advanced materials and manufacturing.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.
