Ukraine Deploys Slovak-made Wolf 25 AD Air Defense System

Slovak company DefTech has announced that the Wolf 25 AD air defense system has been adopted by the Armed Forces of Ukraine and deployed after combat testing.

This was reported by Defence24.

Ukrainian forces delivered positive initial evaluations, and DefTech expects a formal order, though the number of units in service has not been disclosed.

The Wolf 25 AD adds another short-range air defense capability for Ukraine. It uses a Valhalla Turrets combat module equipped with an Oerlikon KBA 25×137 mm automatic cannon capable of firing up to 650 rounds per minute. Ammunition options include proximity-fuzed rounds detonating within approximately 1.5 meters of airborne targets, high-explosive fragmentation incendiary (HEI-T), semi-armor-piercing high-explosive (SAPHE), fragmentation-armor-piercing sub-caliber (FAPDS-T), and armor-piercing sub-caliber shells. DefTech selected the 25×137 mm caliber for its lower weight and cost, wider availability, and greater onboard ammunition capacity while offering performance close to the 30×173 mm round.

The system features a Lotus Lite electro-optical package with thermal and daylight cameras and an AESA AMMR radar. The radar tracks up to 150 targets simultaneously and provides detection ranges up to 20 km for fighter aircraft, 12 km for helicopters, 10 km for missiles, 8–10 km for Lancet-type drones, and 5 km for reconnaissance or microdrones. Four radar panels provide 360-degree coverage. The AMMR radar, also used in Skynex and Skyranger systems, can calculate coordinates of artillery, missile, and mortar impacts and employs electronic counter-countermeasures for operation in high-interference environments.

DefTech stated that the Wolf 25 AD supports protection of advancing ground units, contributing to Ukraine’s layered defense against drones along the front.
