The Russian military has struck a Ukrainian Gyruza-M-class patrol boat using its sophisticated Lancet loitering munition.

Russian news agency RIA Novosti shared a video on Telegram of what appears to be a direct hit on one of the Ukrainian Navy’s few remaining patrol boats.

Although the location of the attack was not indicated in the footage, a former officer in the Russian Navy claimed that the incident happened in the waters of the Kakhovsky Reservoir.

It is not clear if the vessel was damaged or destroyed.

At a length of 75 feet (22.86 meters), the Gyurza-M class armored patrol boat is designed for riverine and littoral missions and accommodates a crew of five.

The boat is armed with BM-5M.01 Katran-M remote-controlled module guns and 30-millimeter ZTM-1 automatic cannons.

Kyiv initially operated seven Gyruza-M-class patrol boats, but four were captured during Russia’s invasion.

The Lancet Drone

Manufactured by Zala and Kalashnikov, the Lancet-3 is a lightweight loitering munition with a three-kilogram (6.6-pound) warhead.

It has a take-off weight of 12 kilograms (26.4 pounds) and can be launched with a rail-mounted catapult system.

The Kamikaze drone can strike targets at a range of 40 kilometers and has an endurance of 40 minutes.

According to RIA Novosti, the Lancet that struck the Gyruza-M-class patrol boat is a new version featuring an 11-pound (4.9-kilogram) warhead.

The previous versions of the loitering munition had two sets of large cruciform wings, while the newest variant only has one, as is shown in the video.
