Acoustic Communication

Breaking Through Ocean's Barriers

Advanced underwater communication systems enable reliable long-range messaging and connectivity across maritime environments, from deep oceans to littoral waters.

Delivering robust and reliable through-water communications across extensive ranges. These sophisticated systems employ very low frequency (VLF) technology and advanced electrodynamic projectors to achieve unprecedented levels of underwater connectivity. Modern acoustic communication solutions can operate effectively in various maritime environments, from broad ocean areas to shallow waters, supporting diverse naval operations including submarine communications, unmanned underwater vehicle (UUV) control, and special forces operations. 

The technology incorporates multimode receivers and powerful projectors that maintain clear communication channels despite challenging underwater conditions. With operating frequencies ranging from below 10 Hz up to 3 kHz and source levels exceeding 200 dB re 1 µPa @ 1m, these systems provide the essential capability for coordinated underwater operations, enabling seamless integration of subsea assets into broader naval activities.
