Ukraine’s Shadowy “Prymary” Unit Hunted Down Russian Ships and a Helicopter in Crimea

A series of precision strikes carried out by a special unit of Ukraine’s military intelligence agency targeted multiple Russian naval and aviation assets in occupied Crimea throughout February 2026, according to Ukraine’s Main Directorate of Intelligence (HUR) on March 6.

The operations were conducted by the “Prymary” unit, a specialized detachment within HUR under the Ministry of Defense. The group reportedly carried out coordinated attacks against several Russian platforms operating in the Black Sea region.

According to information released by Ukrainian military intelligence, the raids struck several Russian military assets, including naval vessels, aircraft systems, and air defense equipment.

Among the confirmed targets were:

• a Project 22460 patrol ship “Okhotnik”;

• a radar station associated with an S-400 air defense system;

• a Forpost unmanned aerial vehicle;

• a Project 1496M1 naval tugboat;

• a Project 16640 vessel;

• a BK-16 landing assault boat (Project 02510);

• a Ka-27 helicopter.

The strikes reportedly took place across multiple locations in occupied Crimea and surrounding waters.

Earlier, a Russian Ka-27 anti-submarine helicopter was destroyed by an FPV drone launched from a naval drone platform—an unprecedented method of attack.
