This unmanned surface vehicle (USV) was built to provide a measure of defense against a very specific kind of asymmetric warfare, suicide boats (like the one that punctured the hull of the U.S.S. Cole in Yemen). By investigating a suspicious boat, either an approaching vessel or an apparent derelict, the Protector can trigger a suicide attack, or provide a warning to larger vessels. In a less sacrificial role, the USV can also respond directly to threats, with a hail of bullets.
Developed by BAE Systems, Lockheed Martin, and RAFAEL, the Protector is capable of speeds of up to 30 knots. This 30-ft-long robot has a 10-mile range, and is equipped with microphones and speakers, for remote communication between operators and potential hostiles. Its stabilized weapon mount hasn't been tested in combat, but since the vessel itself consists of a rigid-hulled inflatable boat, the Protector isn't necessarily designed to survive a firefight. Once the guns or bombs go off, its job is essentially done.
Although the United States Navy and Coast Guard continue to investigate the Protector, this USV has been an active part of Singapore's Navy since 2005.
