The Drone Duel

A Ukrainian Navy Sargan-3000 uncrewed surface vessel destroyed a Russian Zafir attack drone in the Black Sea. The Ukrainian drone operated on intelligence from the Main Intelligence Directorate (HUR). The Sargan-3000, also known as the Seawolf, is built by Nordex and is one of the main USV types used by the Ukrainian Navy. The Russian Zafir drone is a small, fast USV designed for explosive attacks, similar in size and concept to Ukraine's Magura V3 and V5. The exact location of the fight has not been reported, but it most likely took place in the northwestern Black Sea between Odesa and Crimea.

Weapons and Capabilities

The Sargan-3000 was armed with a Kongsberg Protector remote weapon station equipped with a 12.7mm machine gun. The Russian Zafir was likely armed with a ramming charge. The Sargan-3000 can also carry the Sea Dragon air defence system, a 'FrankenSAM' using Sidewinder or Soviet-era AA-11 Archer missiles. Another notable Sargan-3000 variant is equipped with extensive electromagnetic warfare equipment. The Zafir has an internally mounted motor driving a jet ski type steerable water jet, making it fast and agile.

Russian Drone Operations

Russia has been basing Zafir USVs in northwestern Crimea, in Chornomors'ke, and in a new special base on Lake Donuzlav. The Lake Donuzlav base features dispersed revetments dug into the shoreline to protect the USVs before launching. During attacks, Russian USVs work closely with deep strike drones, particularly the Geran (Shahed) type, which provide oversight and control. The aerial drones are equipped with trainable cameras and can act as repeaters to extend the range of the USV's mesh radios. Several strikes by Russian USVs have been reported, primarily on Odesa, and several Ukrainian warships and naval vessels have been destroyed.
