A new counter-unmanned aerial system (C-UAS) platform developed by Slovak company DefTech has been deployed to Ukraine for field testing, according to an announcement posted by Praise The Steph on X social media.
The system, named Wolf 25 AD, is being trialed by Ukrainian forces amid rising demand for mobile, radar-guided air defense solutions capable of neutralizing drones and low-flying threats.
The Wolf 25 AD is mounted on a V-shaped 4×4 modular chassis and powered by a 450-horsepower, 9-liter engine. It has a top speed of 100 km/h and a range of up to 700 km. Designed for a crew of four — including a driver, commander, technician, and gunner — the vehicle incorporates independent wheel suspension and an automatic transmission system, making it suitable for high-mobility operations.
The primary weapon system is an Oerlikon KBA 25x137mm automatic cannon mounted in a modern turret. It supports multiple types of ammunition, including proximity-fused (PX-HE) rounds for aerial targets and a range of armor-piercing and incendiary variants.

The cannon is capable of firing in single-shot mode or at a rate of up to 650 rounds per minute. The turret also integrates a Lotus Lite electro-optical sensor suite with thermal imaging and daytime cameras, and supports optional auxiliary weapons including MANPADS, ATGMs, and laser-guided rockets.
The core of the system is its AESA-based AMMR radar, which can track up to 150 targets in real time. The radar offers detection ranges of 20 km for fixed-wing aircraft, 12 km for helicopters, and up to 10 km for Lancet drones. Smaller reconnaissance UAVs and FPV drones can be detected at distances up to 5 km.
AMMR radars also feature advanced electronic counter-countermeasures (ECCM), search-on-the-move capabilities, and integration with fire coordination systems for counter-battery and convoy protection missions.

The Wolf 25 AD underwent successful testing in Slovakia prior to deployment in Ukraine.
DefTech says trials are ongoing and customer feedback has been positive. The company anticipates follow-on orders based on performance in the field.
