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.
Technical detail
Core features
Distinct national sonobuoy variants
Active and passive underwater sensing roles
September 2026 production-readiness announcement for five US-spec variants
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
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.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
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.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.
