The new missile was first deployed by the enemy late last year and appears to represent uac’s initial ventures into missile manufacturing. The warhead utilizes an ofab-250-270 high-explosive fragmentation aircraft bomb weighing 250 kg, integrated into the structural frame of the missile's nose section.

The airframe is constructed from a multi-layer fiberglass material with additional reinforcement, while internal elements are made of aluminum alloys.

Equipped with a primary fuel tank and two side tanks, the S-71K has an estimated operational range of up to 300 km. Moving forward, the enemy is considering the possibility of deploying the missile from the s-70 "okhotnik" uav.

Continued access to foreign technologies and components allows the aggressor state to develop new weapons and scale their use in the war against Ukraine.

The DIU continues its systematic work to expose the technological base of the russian defense industrial complex and calls for increased sanctions pressure to limit the aggressor's capacity to wage war.
