The Protector unmanned surface vehicle (USV) was developed by the Israeli Rafael Advanced Defense Systems in response to emerging terrorist threats against maritime assets such as the USS Cole bombing, and is the first operational combat USV in service. It is fitted with a Mini Typhoon Weapon Station. By 2005, it was being first deployed by Singapore Navy, then in encourage of coalition forces in the Sea of Japan and later in anti-piracy duties in the Gulf of Aden. In 2012, Rafael announced that they were building a larger (11 metre) version of the Protector, that would have a greater range, and be equipped with a wider range of weaponry.
Based on a 9 metre (30-foot) rigid-hulled inflatable boat, the Protector is stealthy, fast and highly maneuverable. The vessel's low profile upper structure is sealed and aerodynamic, and its modular platform design allows it to be reconfigured to meet changing mission requirements, such as force protection, anti-terror, surveillance and reconnaissance, mine and electronic warfare. The hull is a deep V-shaped planing hull, with the inflatable section providing stability and endurance. A single diesel engine drives water jets, allowing speeds of 50 knots (92.6 km/h; 57.5 mph).
The Protector offers enhanced surveillance, identification and interception capabilities. It is equipped with a Mini-Typhoon stabilized weapon system, a TOPLITE electro-optic surveillance and targeting system with day and night targeting capabilities through the use of forward looking infrared, charge-coupled devices and laser rangefinders, as well as a public address system.
