Hunter WOLF

Airless Michelin Tweel wheels that cannot be shot flat, 300 km of range and 15 kW of exportable power: the Hunter WOLF from HDT Robotic Systems in Fredericksburg, Virginia, is one of two vehicles down-selected for the US Army's S-MET Increment II alongside the Rheinmetall/Textron bid – eight vehicles for USD 22 million go into evaluation, with an unconfirmed robotics.press report of options for up to 2,195 systems from FY2027.

The 6x6 hybrid weighs 1,600 kg, carries 1,270 kg, measures 250 by 140 by 100 cm, drives at 16 km/h and can be towed at 70 km/h. A diesel or JP-8 generator charges the batteries, and silent electric running covers 12 km. A one-hand controller with a 24 h battery steers it; the RAS-G IOP v6 interface accepts third-party autonomy, and HDT offers its own waypoint kit.

The 2 by 1.3 m deck takes two to four stretchers, a water-purification unit, a CBRNE kit, a footbridge or a mine flail, and the vehicle fits UH-60, CH-47, V-22 and C-130 aircraft. Armed configurations include a remote weapon station up to 30 mm, live-fired in trials, an armoured M2 mount and, at JRTC in 2026, a remotely operated .50-calibre gun with the 101st Airborne Division; the Marine Corps has tested it since 2022.

Figures follow HDT's Rev. 14 datasheet of January 2026; older sources quote 1,100 kg, 450 kg and 100 km for an earlier build. Shown in 2017, fielded since 2022, priced on request. Rivals are the S-MET and the Arion-SMET.
