IZMIR, Turkey — An armed, operational unmanned surface vessel manufactured by U.S. defense contractor Sierra Nevada Corporation washed ashore on Turkey’s Black Sea coast on March 20, 2026, prompting a security response that culminated in the vessel’s destruction in a controlled offshore detonation.
The vessel, identified as an AEGIR-W variant, came aground on a beach in the Yüceler neighborhood of Ünye district in Ordu province. Locals discovered the craft and informed the authorities.
According to a statement issued by the Ordu Governorate, Turkish Navy explosive ordnance disposal specialists conducted a technical inspection of the vesselon March 21.
The examination determined that the craft remained operationally active and was carrying a warhead. Given the assessed risk, authorities made the decision to tow the vessel approximately four kilometers from the shoreline and destroy it in a controlled detonation.

The AEGIR-W is a long-endurance unmanned surface vessel designed for operations in high-threat maritime environments. The platform measures under ten meters in length, is constructed from high-density polyethylene, and is powered by a diesel combustion engine.
It is capable of reaching speeds in excess of 25 knots and carries a maximum payload of 300 kilograms across a range of 500 nautical miles at cruise speed. The vessel can operate either fully autonomously or under direct human operator control, depending on mission requirements.
According to Sierra Nevada Corporation’s product documentation, the AEGIR family — which also includes the AEGIR-F stealth variant and the longer-range AEGIR-H — is designed for intelligence, surveillance and reconnaissance, electronic warfare, offensive operations, and autonomous resupply tasks.
The Black Sea has become an increasingly active theater for unmanned maritime systems since the start of Russia’s full-scale Ukraine invasion in February 2022.
This is the fifth time an out-of-control naval surface drone has been found on Turkish shores since September 2025. In previous cases the vessels were Ukrainian Magura-family craft. This is the first time that a foreign-made system has been confirmed present in the region.
