The Riptide UUVs are used by the U.S. Navy and other government can detect or drive off submarines from dozens

“To affordably conduct peacetime
surveillance and effectively defeat sub-
marines in wartime, the Navy should
increase the role of unmanned systems.
Using manned platforms to conduct
command and control, and unmanned
vehicles to track, deter and engage sub-
marines, could significantly reduce the
costs of ASW operations and enable the
Navy to scale its ASW efforts to match
the growing threat posed by submarine
fleets,” said Bryan Clark is a senior fellow at the
