New DevDroid developments: Wolly 40 combat module, drone detector, and unmanned systems for land, sea, and air

Ukrainian defence tech company DevDroid presented several new developments at the Lviv IT Arena 2025 conference. Previously best known for its Wolly combat modules and ground robots equipped with these turrets, the team has significantly expanded its product line. Among the new solutions are an airborne mothership drone and a relay drone, an unmanned surface vessel, a drone detector, as well as two UGVs developed in partnership with other industry players.

Defender Media took a closer look at the innovations at the company’s stand and spoke with the project team.

Khoryv USV

The small Khoryv USV is designed for operations in coastal and shallow-water zones. It can carry up to 36 kg of payload for 20 km and perform combat missions to destroy coastal fortifications, strike enemy vessels, mine and de-mine coastal areas, as well as neutralise enemy equipment and personnel. Additionally, the vessel can be used for reconnaissance and to support logistics operations.

Khoryv is quite compact: it weighs 90 kg and has a hull only 1.6 m in length and 60 cm in width.

Krykun drone detector

The Krykun detector is designed for the timely detection of and warning about the approach of enemy unmanned aerial vehicles, particularly FPV drones. The device scans a wide frequency range, detecting control channels and video signals, and recognises UAVs by their signal “signatures”. Currently, the detector is capable of recognising enemy Orlan, Zala, Kometa, Lancet, as well as KABs, FPVs, and Mavics from a distance of up to 4 km.

In the event of a threat, Krykun issues a loud voice warning in Ukrainian. Developers are currently working on adding English-language warnings and creating a display to visualise frequencies.

Tango Mother Drone

The Tango system is a carrier for two FPV strike drones for conducting long-range operations. The drone acts as a relay, allowing the operator to remain at a safe distance and doubling the operational radius of standard FPV systems.

Tango is designed for strike and reconnaissance missions: detecting and striking military infrastructure, EW systems, and air defence systems. Its flight time reaches up to 120 minutes, with a range of up to 55 km. The system is also equipped with GPS modules and can transmit telemetry, as well as video and audio signals.

Recruit relay drone

Recruit is designed to expand the operational radius and maintain stable communication. When powered by a ground source, the drone can remain airborne for 240-300 minutes, and when using on-board batteries, it can fly for up to 40 minutes. Recruit can fly a distance of up to 4 km, maintains an altitude of 120-150 m, is resistant to EW, and is capable of operating in wind speeds of up to 7 m/s, in foggy and rainy conditions.

Reconnaissance-strike UGV Droid NW-40 with Wolly 40 combat module

The Droid NW-40 UGV is a new DevDroid product that uses the NUMO from Tank Bureau as its mobile platform. It is equipped with DevDroid’s new Wolly 40 combat module for an MK-19 grenade launcher, as well as the Droid Box control system, another in-house development.

The new Wolly 40 combat module is faster than its predecessor and has much wider angles of rotation (almost 360 degrees horizontally and up to 80 degrees vertically). “Wolly 40 can be mounted on UGVs, as we’ve already done with the Droid NW-40, or used as a stationary combat module,” the company explained.

In the future, the manufacturer plans to make the Wolly 40 turret universal, so it can work with machine guns and “some other systems we can’t yet disclose.”

The Droid NW-40 can engage lightly armoured and unarmoured targets, enemy personnel, and firing positions. It can detect a typical target, such as an APC, at a distance of 1,500 m. Its autonomous operation without movement can last up to 72 hours. The system is remotely operated, while built-in AI elements enable autonomous target detection, acquisition, and tracking.

Maul EVAC evacuation UGV

The Maul EVAC is a ground robot designed for the evacuation of seriously wounded soldiers from the battlefield in conditions where the use of other transport is not possible. The system is based on an ATV chassis with an internal combustion engine, which allows it to reach speeds of up to 50 km/h and does not require recharging.

A special armoured capsule for transporting the wounded is capable of withstanding FPV drone strikes. The robot has a payload capacity of up to 200 kg and a deployment time of up to 10 minutes. Its range on hard-surface roads is 150 km, and on off-road terrain it is 100 km.

This UGV is not an original DevDroid development. It was initially created by soldiers of the 1st Independent Medical Battalion, after which DevDroid acquired a licence for further development and refinement.

Recently, Defender Media also reported on IXIAN, a company that debuted with two UAV systems and a logistics UGV.
