Ukraine may receive the latest air defence system, Wolf 25 AD, developed by the Slovakian company DefTech a.s.. This is a modern platform created with the combat experience of the war against Russia in mind, including the ever-changing tactics of using drones, helicopters and light armoured vehicles.

The system is built on a modular 4×4 chassis with a V-shaped bottom, has an independent suspension, a 450 hp diesel engine and a range of up to 700 km. The crew consists of four people: a driver, a commander, a technician and a gunner. The maximum speed is up to 100 km/h.

The Wolf 25 AD is armed with a 25×137 mm Oerlikon KBA automatic gun capable of firing in various modes, including up to 650 rounds per minute. Depending on the task, the system can use:

  • High explosive fragmentation rounds with remote detonation (Proximity Fuze) at a distance of 1.5 m - to engage aerial targets such as FPV drones or Lancets;
  • Incendiary, armour-piercing and sub-calibre projectiles with tracers - to combat lightly armoured targets (BMPs, APCs, BMDs).

The system is also equipped with the Lotus Lite optoelectronic module with thermal imager and daytime cameras, and has the option of integrating auxiliary weapons such as machine guns, man-portable air defence systems, ATGMs, Gatling guns, laser or unguided missiles.

The key element is the AESA (Active electronically scanned array) AMMR radar system with a computer-controlled phased array antenna. It consists of four panels and provides a 360° view, tracks up to 150 targets in real time and is capable of detecting

  • aircraft - up to 20 km away
  • helicopters - up to 12 km
  • missiles - up to 10 km,
  • Lancet-type kamikaze drones - up to 10 km,
  • quadcopters and FPV drones - up to 5 km.

The radars are designed to operate on the move, have high noise immunity, and are capable of calculating the trajectories of enemy artillery attacks. They are water-cooled and require an additional power generator.

At the moment, the system is already in Ukraine, where it is undergoing combat testing, firing and evaluation. According to the manufacturer, the results are positive, and the company is expecting the first orders in the series.

Prior to that, Wolf 25 AD was successfully tested in Slovakia. The system is positioned as an effective solution for short-range air defence and protection against massive attacks by drones and light armoured vehicles.
