The Future of Drone Warfare: The Rise of Maritime Drones

When the Houthi rebels in Yemen first used maritime drones in January 2017, the assault on a Saudi frigate highlighted the little-known development of sea-capable semi-autonomous weapons. While maritime drone technology is not yet proliferating at the pace of aerial drones, countries like the United States, the United Kingdom, and Russia are already looking seaward in terms of drone development.

The U.S. Navy sees maritime drones as a key part of the Third Offset strategy, which seeks to leverage next-generation technologies against America’s adversaries. Unmanned Underwater Vehicles (UUVs) will enable the creation of an underwater intelligence, surveillance, and reconnaissance network that mirrors U.S. aerial and land-based networks.  According to a 2016 DoD report entitled “Autonomous Undersea Vehicle Requirement for 2025,” Submarine based UUVs will be used to extend the effective range of the host submarine’s sensors and weaponry. These drones will also be used to carry out missions considered too dangerous for crewed vehicles, like mine countermeasures, and to serve as decoys to disguise the locations of manned submarines.

According to a 2016 U.S. Naval Institute news report, Commander of U.S. Submarine Force Pacific Rear Adm. Fritz Roegge said at the Oct. 27 Naval Submarine League annual symposium that the Navy would have a functioning UUV squadron by 2019. In remarks delivered aboard the USS Princeton on February 3, 2016, Defense Secretary Ash Carter said the United States would invest “$600 million over the next 5 years” in UUVs.

In April 2016, the Defense Advanced Research Projects Agency (DARPA) christened the Sea Hunter, a 132-foot autonomous ship designed to locate enemy submarines. In December 2016, the U.S. Navy demonstrated that a swarm of autonomous surface vessels could work cooperatively to patrol a harbor. The drone boats are programmed to identify and track potentially threatening vessels, both surface craft and submarines. The Echo Voyager, introduced in 2016, is a large reconnaissance UUV that can operate autonomously for six months and surface to send data to its operator via satellite.

The British Royal Navy appears to share the United States’ interest in maritime drones. The United States and United Kingdom staged the first Unmanned Warrior exercise in Scotland in October 2016, where drones from different countries were networked together to work as a unit.

In August 2015, Russia launched a retrofitted SSBN capable of launching crewed mini-subs as well as UUVs like the deepwater surveillance drone Klavesin-1R.  In September 2015, the Washington Free Beacon reported that Russia was developing a stealthy, nuclear-armed UUV called the “Status-6”. Documents shown on Russian TV in November 2015 appeared to confirm the initial reports, though the apparent security lapse may well have been a deliberate effort to spread false information about the program.
