Ukraine Develops Domestic Armored Doors for HMMWV

The Ukrainian company Iron Nuts has developed domestic armored doors for HMMWV vehicles in the M1151A1 version. Work on a next-generation version is already underway.

The company reported this on its Facebook page.

It is reported that the armored doors provide PZSA-4-level protection, while the armored windows are rated SK-4, corresponding to protection against steel-core rounds, including the 7N10 5.45×39 mm and 57-N-323S 7.62×54 mm cartridges at a distance of 10 meters.

HMMWV in the Defense Forces

As of February 2025, the Defense Forces operated a fleet of about 5,000 HMMWV off-road vehicles in various configurations, most of which were supplied in unarmored versions as part of military assistance from the United States and other countries.

The Ukrainian military widely uses these vehicles to carry out combat missions and logistics within brigades of the Armed Forces of Ukraine, the National Guard, and special units of the Defense Intelligence.

Due to their mobility and off-road performance, HMMWVs are often used as platforms for heavy weapons, including multiple launch rocket systems, air defense systems, and other armaments mounted on M1152 two-seat versions.

Ihor Simutin, a major in the Armed Forces of Ukraine and a logistics specialist in vehicle repair, shared with Militarnyi that at a certain stage of the war, the United States started supplying Ukraine with category-four equipment to serve as a source of spare parts for the existing fleet. This applies to M-ATVs and HMMWVs in general.

Category four of serviceability means the equipment is formally considered unserviceable. Only category five is worse, effectively scrap metal. However, mechanics refused to dismantle such vehicles and returned them to service.

“We repaired one of two or three, and then even took them out and repaired them further,” Ihor Simutin said.

Given the large number of similar vehicles in Ukraine, a structured repair system for off-road vehicles has been established. Brigade workshops can perform minor repairs and replace damaged components. In cases of severe damage, vehicles are sent to repair centers under the Logistics Forces Command.

In addition to repairs, the Armed Forces of Ukraine have launched a large-scale program to localize spare parts production. This was a necessary step to reduce dependence on long delivery times for original components from abroad.

“All types of rubber components, all silent blocks, bushings, dust covers, armored windshield glass of any class, plastic elements, plastic hoods, metal roofs, metal doors, run-flats, radiators of any type, repair of all types of engines and automatic transmissions — all of this is localized in the Armed Forces,” Simutin said.
