Ukraine's drone attacks met with Russian retaliation in Crimea.

Russian forces repelled a drone attack by Ukrainian unmanned surface vehicles (USVs) on Sevastopol Naval Base. The drone was shot down by machine guns, not missiles. The attack was considered a breakthrough in naval warfare, standing as the first large-scale suicide naval drone attack in naval history. Russia needs to develop a sophisticated defense system against surface drones consisting of smart munitions and missiles.
