Two of the CMRE’s most valuable assets are their sophis- ticated autonomous underwater vehicles (AUVs), capable of operating with a degree of independent decision-making abili- ties. The CMRE is working to give the AUVs the capability to listen, to evaluate and to signal the presence of submarines to operators in the command and control center.

Like the increasingly used unmanned vehicles for air and land, AUVs can operate more and more ? exibly in the littoral and open oceans. And, as further systems are introduced into the mix, the way potential enemies have been used to working underwater will begin to be challenged.

LePage said, “ASW has for years relied on certain remote- controlled, monitored or unmanned sensor platforms, such as the sonobuoys deployed by Maritime Patrol Aircraft and

Helicopters, and permanent or deployable sensing arrays.
