Turkish defence company Kayacı Defence exhibited its OKHAN unmanned surface vehicle (USV), now configured for coast guard missions, during the Indo Defence 2025 exhibition held in Jakarta, Indonesia, from 11 to 14 June.
The OKHAN USV was initially unveiled at the DIMDEX 2024 exhibition in Doha, Qatar. Following its debut, the company began working with the Turkish Coast Guard to tailor the platform specifically for law enforcement and maritime security operations. A live demonstration of the vessel was conducted in January 2025, with the participation of officials from the Turkish Coast Guard.
According to Kayacı Savunma CEO Hakan Kayacı, a protocol was recently signed with the Turkish Coast Guard and the Presidency of Defence Industries (SSB) to begin formal trials of the vessel. The evaluation phase, expected to last between six to nine months, aims to determine additional operational requirements that will further align the platform with the specific needs of the Turkish Coast Guard.
In parallel, Kayacı Savunma has reached an agreement with Anadolu Shipyard (ADIK) to develop a second prototype of the OKHAN USV. This version is expected to include various upgrades, including a slightly larger hull and a revised payload configuration. Naval News has learned that both companies are close to finalizing a cooperation contract focused on enhancing the vessel’s capabilities through joint development.
The company also showcased its Towable Rigid Passive Radar Reflector, the KYC-PRR125, solution at the show. It’s a passive radar reflector system that can be towable at high speeds by the surface vessels. The system is equippped with metal components that can provide very high radar cross-section to be operated for frequencies from 1GHz and more.
KYC-PRR125 is designed to be used as a synthetic target especially during the naval drills. The reflector can be towed at 40 knots at sea state 1, and also possible to be towed at 20 knots when the sea state is 5.
About OKHAN USV
OKHAN is an 11.4-meter autonomous surface platform equipped with a hybrid propulsion system that combines diesel and electric engines. The vessel can reach speeds up to 27 knots, with a range of 270 nautical miles at top speed and 400 nautical miles at 20 knots. Line-of-sight communications provide a control range of 27 kilometers, while SATCOM enables operations beyond 200 kilometers.
The vessel has a maximum payload capacity of 1,000 kilograms and can be equipped with mission-specific systems such as weapon stations, radar cross-section enhancers, RF jammers, and various sensors. Its integrated sensor suite includes a 24-kilometer-range navigational radar, electro-optical systems, satellite telemetry, and standard navigational safety equipment.
Designed for a range of coastal missions, OKHAN is capable of supporting operations including surveillance, reconnaissance, maritime security, search and rescue, border enforcement, environmental monitoring, and irregular migration control. The vessel is also compatible with joint operations involving UAVs and other USVs, offering expanded mission flexibility.
Kayacı Savunma states that the platform can maintain position accuracy within one meter and remain stationary on a coordinate for extended periods despite varying sea conditions.
