Ukraine flags that Russia could have a secret fleet of autonomous military vessels stalking the seas

Ukraine alleges Russia may possess a covert fleet of autonomous vessels lurking in international waters, according to recent claims. The Ukrainian military intelligence service asserts that new drone boats can traverse great distances and achieve high speeds without human oversight. A catalog released by Ukrainian authorities outlines various unmanned vessel models, each with distinct capabilities.

The Zefir and Orkan models reportedly cover up to 400 kilometers at speeds of 35 knots and can carry 400 kilograms of cargo. The BEK-1000, a heavier variant, is capable of hauling a full metric ton over distances exceeding 500 kilometers at 40 knots. Another vessel, the Katran, appears designed specifically for launching first-person-view drones over distances of 100 to 200 kilometers.

The Murena-300s variant extends its range to 500 kilometers and can be equipped with torpedoes or first-person-view drones. Ukraine's intelligence agency also highlights the existence of more basic scouting boats alongside advanced combat platforms designed for coastal strikes and attacks on shipping near contested waters. Earlier prototypes of these drone vessels date back to 2014, with later versions boasting improved ranges and payloads.

These platforms suggest a rapidly evolving naval drone program aimed at reconnaissance and offensive operations in contested maritime zones near Ukraine. Ukrainian President Volodymyr Zelenskyy has called for intensified pressure on Russian territory, urging allied nations to bolster air defense systems ahead of potential autumn mobilization inside Russia following recent elections.

However, the veracity of these claims remains uncertain, with analysts cautioning that some figures may reflect aspirational rather than operational capabilities. The vulnerability of unmanned systems to jamming and detection is also acknowledged despite their expanding capabilities under advanced electronic warfare conditions.
