According to New Scientist, the Ukrainian Navy used an uncrewed vessel earlier this month to attack and sink an uncrewed naval robot operated by Russian forces. The episode is described as the first naval engagement in which both sides were uncrewed vessels.
The clash underscores how quickly drone technology is moving from the air to the sea. While uncrewed surface vessels have been used for reconnaissance and strike missions before, this appears to be the first time two such systems fought directly against each other.
The report does not provide details on the vessels' specifications, the exact location, or how the Ukrainian craft was controlled. It notes only that the Russian-operated robot was sunk in the encounter.
