Operating context
See the Canadian systems behind submarine detection at sea. From its Dartmouth operation, Ultra Maritime develops and builds towed arrays in Canada and manufactures or integrates sonobuoys, hull-mounted sonar, containerized Sea Tracker systems, and lifecycle support for Royal Canadian Navy and allied undersea-warfare programs. Its published capability portfolio includes Sea Tracker Containerized ASW System, Sea Lancer Towed Sonar Arrays, Sea Searcher Hull-Mounted Sonar & Transducers.
Canadian footprint
ACOA describes Ultra Maritime's Dartmouth, Nova Scotia engineering and manufacturing base, including Canadian-developed towed-array and sonobuoy work. It identifies Halifax-class underwater-warfare upgrades and initial River-class sonar/anti-torpedo contracts. This Canadian delivery evidence does not establish that every product in Ultra Maritime's international portfolio is made in Canada.
Dartmouth, Nova Scotia is the published city-level context for Ultra Maritime. It does not imply a street address or exact facility location.
Ultra Maritime offers a Canadian sonar manufacturing connection in Dartmouth and a wider multinational undersea-sensing portfolio. Its Lanternfish report adds a specific Sea Spear and SSQ-125B demonstration to investigate. Canadian buyers and partners should establish the configuration, local workshare and acceptance evidence before treating that group demonstration as a Canadian-delivered operational capability.

Naval undersea-warfare integration and lifecycle support
Read technical summary
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.
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.
Core features
Engineering support through shore installation, trials and acceptance
Spares provisioning and readiness preparation
Dartmouth-led coordination of River-class underwater-system work
Recorded applications
River-class Destroyer build and acceptance
Transition of undersea-warfare systems into operational service
Long-term fleet readiness and domestic support capacity
Sea Lancer is Ultra Maritime's modular family of active and passive towed-sonar systems. Its open architecture allows different sensing and processing elements to be integrated for naval underwater awareness. Canadian programme evidence includes the company's account of twelve Halifax-class UWSU arrays; Sea Tracker provides a separate containerized route for experimenting with towed technologies.
Evidence of maturity
A marketed sonar family with an established Canadian programme reference; specifications and integration maturity vary by array and host vessel.
Commercial availability
Available through naval system procurement and platform integration; host requirements determine the configuration.
Core features
Active and passive towed-sonar configurations
Open modular architecture for system integration
Canadian Halifax-class UWSU array programme reference
Recorded applications
Long-range submarine and torpedo-threat detection
Surface and subsurface platform situational awareness
Crewed, optionally crewed and uncrewed anti-submarine-warfare missions
Sea Revealer comprises Ultra Maritime's acoustic sonobuoy family across US, UK and Canadian variants. In September 2026 the company announced production readiness for five updated US-spec variants. Its stated production rate spans three countries, so the announcement does not establish Canadian manufacture of every variant or a Canadian-only production capacity.
Evidence of maturity
The manufacturer describes a production portfolio. Readiness of individual variants and Canadian workshare must be read separately from global output claims.
Commercial availability
Procurement depends on the national specification, variant and integration requirements; current lead times are not disclosed.
Core features
Distinct national sonobuoy variants
Active and passive underwater sensing roles
September 2026 production-readiness announcement for five US-spec variants
Digital hull-mounted sonar and acoustic transducers
Read technical summary
Sea Searcher combines hull-mounted sonar and acoustic-transducer engineering for naval underwater sensing. Ultra Maritime describes digital processing and configurable ship integration. Its Canadian manufacturing role is supported by a three-shipset River-class hull-sonar order; that order and the wider product family should be distinguished from completed installation on the future destroyers.
Evidence of maturity
Published product family with a Canadian production order; the inspected sources do not confirm completed River-class shipset acceptance.
Commercial availability
Offered for ship-specific procurement and integration; configuration and acceptance requirements are programme-dependent.
Core features
Digital hull-mounted sonar architecture
Acoustic-transducer design and manufacturing
Three River-class hull-sonar shipsets ordered with Dartmouth manufacturing
Recorded applications
Close-range submarine detection and tracking
Ship navigation and underwater situational awareness
Inner-layer anti-submarine warfare and torpedo defence
Sea Spear is Ultra Maritime's deployable passive-sonar system. The manufacturer reports demonstrating it with an SSQ-125B active sonobuoy during Lanternfish 2026 for underwater-vehicle detection and localization; product-level Canadian workshare and operational acceptance remain unconfirmed.
Evidence of maturity
Manufacturer-reported Lanternfish 2026 demonstration; no operational acceptance is established.
Containerized submarine detection and towed-sonar integration system
Read technical summary
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.
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.
Core features
Standard 20-foot ISO container form factor
Integration of active, passive, surveillance and torpedo-defence towed technologies
DRDC experimentation route supported by ACOA and COVE
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
Public record
Recent activity
Aug 13, 2026
Ultra Maritime reported on August 13, 2026 that its Sea Spear passive sonar and SSQ-125B active sonobuoy were demonstrated together during U.S. Navy Lanternfish 2026 for unmanned-underwater-vehicle detection and localization. This remains a manufacturer-reported exercise result, with no Canadian order or operational acceptance established by the announcement.
COVE is collaborating with Ultra Maritime Canada, DRDC and ACOA on the containerized at-sea towed-array testing initiative in Dartmouth.
Project support and ecosystem development
Atlantic Canada Opportunities Agency
ACOA has provided project support and advocacy for Ultra Maritime's Canadian defence and marine work and is identified as a supporter of the Sea Tracker initiative.
River-class systems and lifecycle contracting
Lockheed Martin Canada
Lockheed Martin Canada has awarded Ultra Maritime Canadian Surface Combatant and River-class work covering hull-mounted sonar production and undersea-warfare lifecycle support.
Sea Tracker experimentation partner
Defence Research and Development Canada

Deployable sonobuoys distribute acoustic sensors across a search area so teams can detect, localize and track submarine contacts beyond a single ship's organic sensor range.
Sea Searcher Hull-Mounted Sonar & Transducers may help teams working on Sovereign defence capability areas by contributing to detection and situational awareness, autonomous and uncrewed systems, and cyber and digital operations.
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.
