Advanced Underwater Glider
The SEAEXPLORER 1000-M glider is an autonomous unmanned underwater vehicle that has been specially designed to undertake naval and defense missions such as REA (rapid environmental assessment), acoustic intelligence and anti-submarine warfare. The underwater glider can be equipped with a variety of payloads including data securing, acoustic optimization and optimal integration into naval forces.
Solutions for Special Forces
ALSEAMAR offers a range of manned submersibles and diver propulsion vehicles to meet the needs of combat divers and special operations warfare.
DPV Murene
Murene is a next-generation underwater propulsion system for combat divers and special operations frogmen, with the ability to transport two fully-equipped personnel.
Featuring an ergonomically-optimized and hydrodynamic design, it can be operated in manual or semi-autonomous piloting modes.
Coryphene
Coryphene is a proven swimmer delivery vehicle platform that can transport up to three divers with full equipment. It can be equipped with Nitrox gas and offers an operational range of up to 50 nautical miles.
The easy-to-pilot vehicle is ideal for a range of subsea defense applications including ISR, infiltration and exfiltration of special forces units, and assault of onshore or offshore targets.
ExoJet
ExoJet is a body-worn propulsion system that is designed to propel a fully equipped diver or frogman through the water in highly challenging conditions. Designed in conjunction with a fully operational French combat diver unit, it allows the wearer to withstand strong currents and significantly extend their operational range.
The lithium-ion battery-powered system includes thrusters with magnetic coupling technology, a belt-worn main control unit, and an optional human-machine interface that can be worn on the forearm and provides full control as well as vital functionality such as speed and battery info, timers and alarms.
Radiocommunications Solutions
ALSEAMAR are highly experienced in the design, simulation and manufacture of active and passive RF antennas for naval surface vessels, and have provided solutions for many French and allied navy programs. The company offers a wide product range including VLF/LF, HF, V/UHF and UHF options, as well as high-performance multi-couplers for input/output signal routing.
Submarine Antennas
ALSEAMAR’s compact multifunction submarine antennas are installed in a hoistable mast for easy deployment, and cover a wide range from VLF to hyper-frequencies.
In conjunction with switches, filters, duplexers and other RF components, these antennas allow simultaneous transmission and reception of several frequencies.
Expendable Communication Buoys
The X-SUB range of tethered expendable communication buoys (ECBs) provides submarines with the capability to communicate with and receive information from sources above the surface while remaining submerged, ensuring maximum stealth. After use, the systems scuttle themselves and sink.
AIS and ADS-B status, GPS position, tactical datalinks and V/UHF communications can all be managed either from the submarine’s operations center or from a ground control station.
BLACK BIRD System
The BLACK BIRD system equips deepwater submarines with a UAV-launching capability that allows the vessel to collect vital real-time data above the surface while remaining submerged for maximum covertness.
The system utilizes a compact quadcopter drone launched from a tubular underwater vehicle that delivers it to the surface and ejects it using compressed air, as well as a communications antenna relay that floats on the surface to transmit data from the drone to the submarine.
