Long Range Covert Communication with Submarines

LRAM System Components

LRAM System Concept Illustration

LRAM System Concept with Expendable Buoy and Persistent USV Options

LRAM provides integrated under water (UW) communications covering both broad ocean areas and the shallows up to the shore line.

The common LRAM modem architecture can be applied to submarine, UUV, and diver communication as well as remote activation of underwater devices. LRAM also enables the production of a multimode receiver capable of receiving all modes, and will allow 2-way communications with a distressed submarine.

LRAM utilises a proven scalable modem software architecture designed to provide robust, reliable, and power-efficient through-water communications to extended ranges.

The system enables co-operative Anti-Submarine Warfare (ASW) between submerged submarines and UUVs and air and surface assets. LRAM provides on-demand connectivity to submarines and UUVs operating in direct and associated support, increasing the value of UW platforms as fleet assets.
