Sea Tracker packages Ultra Maritime's towed underwater-sensing technologies in a standard 20-foot ISO container for integration on a wider range of vessels. The December 2025 announcement identifies a DRDC experimentation programme with ACOA and COVE support. It establishes a funded integration route; the company's comparison with frigate performance remains an attributed claim.

Use & integration
Recorded applications
At-sea evaluation of next-generation towed arrays
Rapid deployment of submarine detection onto available vessels
DRDC experimentation and development of future anti-submarine-warfare concepts
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Contract announcement for experimentation and concept development; fleet adoption and independent comparative performance are not established.
Commercial availability
A programme-based integration offering requiring host-vessel and mission configuration, rather than a demonstrated universal plug-in capability.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
Sea Tracker combines rapidly deployable submarine detection with active and passive towed-array integration, making it a direct fit for underwater detection, classification, tracking and experimentation.
The system is designed for uncrewed and non-traditionally crewed platforms, creating a credible path to add persistent undersea sensing to autonomous maritime patrol concepts.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.
