Swappable calibrated sensors and moving-vessel profilers for sound-speed and water-column measurement, with configuration-specific depth and support limits.
AML combines interchangeable calibrated sensor heads, multiport instruments and moving-vessel deployment systems for water-column measurement. X2change heads retain calibration across compatible instruments; AML-1/3/6 provide different sensor capacities. The supplier gives MVP30 V2 51 m profiling at eight knots and MVP30-350 V2 121 m at that speed, with 185 m and 440 m cables respectively. MVP Roam is a separate vertical-profiling configuration rated by AML to 60 m with up to four parameters. A NOAA-hosted 2021 survey report documents older MVP30-350 sound-speed acquisition and Ethernet/UDP delivery into survey software.
Technical detail
Core features
Swappable sensor heads with embedded calibration
AML-1/3/6 one/three/six ports; AML-6 external connections support eight sensors
MVP30 V2: 185 m cable, 51 m depth at eight knots
MVP30-350 V2: 440 m cable, 121 m depth at eight knots
MVP Roam: supplier-stated vertical profiling to 60 m and up to four parameters

These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Commercial instruments with supplier configuration documentation and historical operator evidence for MVP30-350. MVP Roam's stated envelope is separate. Legacy MVPx parts support was scheduled only through September 2026; current support needs confirmation.
Commercial availability
AML markets current sensor and profiler configurations through its contact route. The launch's six-to-sixteen-week MVP Roam estimate is dated; present lead time and legacy spares require a supplier quote.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
AML sound-speed measurements can inform the environmental-input layer of underwater sensing. A closed 2025 DND harbour DCLT challenge explicitly uses sound-speed profiles, while the NOAA-hosted survey report demonstrates AML profiling in practice. This derived connection does not supply the challenge's tracking algorithms or establish eligibility, participation or defence acceptance; verify the required sensor accuracy, update rate and interface against the intended processing chain.
Swappable oceanographic sensors and profilers may help teams working on Future submarine operational capability by contributing to maritime and undersea operations and detection and situational awareness.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.

SVx sensor sales in 2026 are limited to remaining stocks with a 90-day warranty, apart from certain OEM obligations; no new 2026 production is scheduled. Calibration continues for the foreseeable future. These limits apply to the legacy line, not the entire AML portfolio.
AML's X2change temperature sensor is field-swappable and rated to 6,000 metres, with stated precision of 0.003 degrees Celsius, accuracy of 0.005 degrees Celsius, and 100-millisecond response time.
