Xeos’ XMA-11K is a self-powered Argos recovery beacon intended to survive submergence to a stated 11,000 m and report Doppler-derived position after surfacing. A conductivity sensor changes its operating state; it does not transmit satellite radio through deep water. The live page and linked brochure give different surface endurance figures under nominal 90-second reporting, so battery chemistry, configuration and duty cycle need confirmation. Argos service registration and an assigned identifier are part of the deployment dependency.

Use & integration
Recorded applications
Recovery of deep-ocean instruments and moorings
Location of surfaced uncrewed-system payloads
Full-ocean-depth equipment recovery planning

These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Established catalog product with a published manual and technical brochure. The inspected sources are manufacturer material; independent full-depth qualification and current delivery lead time were not established.
Commercial availability
Available by manufacturer enquiry. Confirm current hardware/manual revision, battery choice, service compatibility and expected submerged and surfaced duty cycles.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
A deep-rated recovery beacon supports underwater system accountability and recovery, but its role is enabling support rather than primary ISR collection.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.

These records support this capability and its published Mission area and Defence need connections. A source count is not a count of independent confirmations.
