Long-Range Acoustic Messaging provides integrated underwater communications with submarines at long ranges enabling tactical flexibility such as mission change/update, targeting re-assignment, covert exchange of vital of information in littoral waters and more.

LRAM also enhances safety by providing reliable, extended, two-way communications with a distressed submarine. LRAM combines SATCOM/radio with underwater acoustic communications through an expendable buoy or persistent USV for tactical messaging covering broad ocean/sea areas and the shallows up to the coast line.

LRAM is a GeoSpectrum product, a wholly owned subsidiary of Elbit Systems Ltd.
