Raytheon demonstrated the ability to communicate in real time with a submerged submarine at classified speeds and depths. This capability, which addresses one of the most significant shortfalls in submarine communications, was exhibited for the 's Royal Navy during an at-sea trial of Raytheon's Deep Siren Tactical Paging (DSTP) system.
The U.K. Ministry of Defense reported that Deep Siren demonstrated "the first step toward a transformational capability that will change the way we operate submarines in the future."
The evaluation, which took place during the U.K. Royal Navy's TAURUS 09 deployment, follows U.S. Navy testing conducted in 2008 that culminated with a successful military utility assessment.
