Israel’s leading defense companies have developed three remarkable robotic vessels that can patrol dangerous waters, hunt underwater threats, and respond rapidly to maritime dangers without putting sailors directly in harm’s way.

Israel’s three biggest defense manufacturers are helping shape the future of warfare at sea—and each has developed a different kind of robotic vessel.
Israel Aerospace Industries (IAI), Rafael, and Elbit Systems have created unmanned boats designed to protect coastlines, confront maritime threats, and carry out dangerous missions without risking sailors’ lives.
These vessels are not simply smaller versions of traditional warships. Equipped with advanced sensors, navigation systems, and specialized equipment, they represent three different approaches to robotic naval warfare.
IAI’s Katana: The Interceptor
IAI’s Katana emphasizes speed and flexibility. Measuring approximately 39 feet long, it can reach an impressive 60 knots, or about 111 kilometers per hour.
Its exceptional speed makes it well suited for rapid responses to suspicious vessels or emerging threats, while its modular design allows operators to adapt its equipment for coastal surveillance, harbor security, and protection of offshore gas installations.
Another important advantage is its ability to switch between manned and unmanned operation, giving naval commanders greater flexibility when planning missions.
Rafael’s Protector: The Patrol Boat
Rafael’s Protector is a robotic security guard for the sea, designed to patrol sensitive waters, protect naval forces, and defend ports and coastal infrastructure.
Unlike an ordinary patrol boat, Protector can also carry remotely operated weapons, allowing naval forces to confront certain threats without exposing sailors to enemy fire.
Its cameras, sensors, and remote-control systems allow operators to monitor suspicious activity from a safe distance. Protector has also been operationally deployed, demonstrating that robotic naval security is already a practical reality.
Elbit’s Seagull: The Hunter
Elbit Systems’ Seagull is a robotic hunter designed to detect threats hiding beneath the waves. Operating on the surface, it uses advanced sonar equipment to search for submarines and dangerous sea mines.
These underwater threats can endanger warships, block shipping routes, and threaten vital maritime infrastructure.
Seagull can be equipped for mine countermeasures, anti-submarine warfare, electronic warfare, and maritime security. Its interchangeable equipment allows the same vessel to undertake different missions without requiring an entirely new platform.
Why Israel Needs Robotic Warships
Israel’s Mediterranean coastline includes major ports, busy shipping routes, and offshore natural gas installations that are vital to the country’s economy and energy security.
Protecting these assets requires constant surveillance and the ability to respond quickly to potential threats, including hostile boats, underwater explosives, and enemy submarines.
Robotic vessels can help extend the Israeli Navy’s reach while reducing the risks faced by sailors. They can also undertake routine patrols and dangerous reconnaissance missions that might otherwise require manned vessels.
Three Israeli Giants, One Naval Revolution
Katana, Protector, and Seagull demonstrate how Israel’s defense industry is developing complementary solutions for modern naval warfare.
They cannot replace missile boats, submarines, or larger warships, but they can provide additional layers of protection while allowing naval commanders to deploy their personnel and resources more effectively.
Together, these three vessels demonstrate how Israel is bringing its technological ingenuity to the world’s oceans.
One intercepts, one patrols, and one hunts. All three point toward a future in which Israeli-built robotic vessels can take on dangerous missions while keeping sailors out of harm’s way.
