D-21 (D-21-11 / D-21-12R)

Tyres that keep rolling after being shot through are a small but telling design choice on the D-21, the wheeled logistics UGV from Ukraine's FRDM Group that the defence ministry codified in January 2025. The vehicle comes in two forms: the unarmed D-21-11 and the D-21-12R with a remote weapon station mounting a 12.7 mm Browning M2, shown by Kyiv Post and in ministry photos.

It carries 200 kg of supplies or a casualty, and its official control range is 5 km; in a full-load test it covered 18 km while using 75 percent of the battery. The electric drive is quiet, the low-pressure off-road tyres tolerate punctures, and control is manual or automatic along a stored route over a channel designed to resist jamming. Empty weight, speed and dimensions are not published.

Presented in 2024, the D-21 has served with the Ukrainian Armed Forces since January 2025, and pricing is on request. In the same 200 kg class the Starlink-controlled Volya-E is the closest rival, while the Tarhan 2K offers similar capacity for USD 3,000 but without an armed derivative.

The D-21 is typical of Ukraine's approach: simple construction, resilient running gear and the option of the same heavy machine gun that larger robots carry.
