Ultra Maritime supports the transition of River-class underwater systems from shore installation through sea trials and acceptance. Its May 2026 Lockheed Martin Canada contracts cover engineering, spares and readiness activity, complementing separately announced hull-sonar and torpedo-defence shipsets. DND places the destroyers in construction, with first delivery planned for the early 2030s.
Technical detail
Core features

Acceptance
Spares
Lifecycle support
Use & integration
Recorded applications
River-class Destroyer build and acceptance
Transition of undersea-warfare systems into operational service
Long-term fleet readiness and domestic support capacity
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Contracted build and acceptance support; an operational River-class fleet is not yet established.
Commercial availability
Programme-specific integration and support are contracted through Lockheed Martin Canada; additional commercial scope requires agreement.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
The lifecycle scope helps bring the River-class underwater-warfare sensors and defensive systems through integration, trials and acceptance into sustained fleet readiness.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.
