NIKA ASW SENSOR

Persistent undersea threat detection with autonomous acoustic sensing, real-time satellite reporting, and long-endurance maritime surveillance.

Maintaining awareness beneath the surface is critical to effective maritime security operations. NiKA from Metocean, and supported in Germany by FLANQ, is a next-generation autonomous platform purpose-built for persistent maritime monitoring and undersea threat detection. Equipped with a custom-engineered hydrophone array, it performs high-precision acoustic data collection by cycling through the water column in Classic Mode or holding a fixed depth in Stealth Mode, gathering key intelligence before surfacing to transmit its observations.

PERSISTENT ACOUSTIC SURVEILLANCE

NiKA is built for long-endurance subsurface monitoring, enabling operators to maintain acoustic awareness over extended periods without placing crewed assets at risk. Capable of operating at depths of up to 1,000 metres and remaining deployed for over a year, NiKA strengthens existing undersea surveillance frameworks by complementing fixed sensors, towed arrays and sonobuoys.

LONG-ENDURANCE ACOUSTIC SENSING, DEEP-WATER OPERATIONS, REAL-TIME CONNECTIVITY

REAL-TIME DATA, GLOBAL REACH

NiKA does more than collect intelligence. Using Iridium Certus 100 satellite connectivity, with data rates of up to 88 Kbps, the platform transmits positional and acoustic data back to command networks anywhere in the world. This gives operators timely, actionable insight and supports faster decision-making across distributed maritime operations.

BUILT FOR MODERN NAVAL OPERATIONS

Designed for cost-effective deployment by uncrewed platforms and vessels of opportunity, NiKA delivers covert ISR capability in a compact, form factor with no visible branding. It uses AES-256 encryption for secure operations with automatic scuttling at end of useful life or GPS recovery. It is engineered for practical, mission-ready deployment in demanding maritime theatres. recovery.

NiKA delivers persistent autonomous undersea surveillance with precise acoustic sensing, deep-water endurance and real-time satellite-enabled reporting.

FEATURES

DEEP WATER ENDURANCE

NiKA is capable of operating at depths of up to 1,000 m and can remain deployed for over a year, depending on selected acoustic windows and required depths.

REAL-TIME SATELLITE UPLINK

Using an Iridium 9770 mid-band transceiver, NiKA transmits positional and acoustic data to command networks in real time, enabling informed operational decisions across global areas of interest.

PRECISION ACOUSTIC DETECTION

Its custom hydrophone element samples at 6 KHz across a 10 Hz to 2.4 KHz frequency band and delivers a detection radius of 9.26 km (5 NM).

LOW-SIGNATURE DESIGN

NiKA features a hard anodised aluminium housing and removable magnet activation method. At 25 kg, it is designed to be practical to handle and deploy.
