VPK-3924

The Bear can be used as an armored personnel carrier, chassis for installing ATGMs, mortars and other weapons systems, protected by command post, reconnaissance and patrol, medical vehicles, or convoy escort vehicles (unlike armored personnel carriers, SPM-3 can be used on general roads use).

The machine has a hood housing. The crew of the car - 2 people, landing - up to 10 people. Hinged doors for landing and landing are provided at the rear of the hull. The bottom has a V-shape, which helps to efficiently dissipate the energy of the explosion. The car suspension is completely independent, torsion bar, unified with the BTR-90 suspension. The machine’s transmission used serial units and assemblies used on trucks of the Ural family. The engine of the first prototype is YaMZ 7601.10 (diesel, six-cylinder, V-shaped, 300 hp). The declared overhaul life of the vehicle is 250,000 km, for the engine - 800,000 km ^[2] , which exceeds the similar indicators of most wheeled and tracked armored vehicles. Cruising range of 1400 km. In the second and third samples, an in-line 6-cylinder YaMZ-536 engine with a power of 312 hp was installed.

The machine has a spaced differential armored protection. The body and glass can withstand the hit of a 7.62 mm armor-piercing bullet fired from the SVD rifle from a distance of 100 meters ( ballistic protection class 6a (GOST R 509-63 ). The machine withstands blasting of 6 kg of TNT under the wheel of the explosive device (class 2a of mine protection according to STANAG 4569. ) High ground clearance (500 mm) and a relatively high gross vehicle weight (12,000 kg) contribute to the high mine resistance along with the V-shaped bottom. Also, the machine has a filter-ventilation unit.

It is possible to install various types of weapons on the machine, depending on the tasks performed. It can be either machine guns of various calibers, or ATGM systems, automatic grenade launchers, etc.

As of June 2014, VPK-3924 “Medved” is completing state tests for all types of external influences, including undermining ^[5] . Based on the test results, an improved model of the machine was made. The main directions of changes: the use of the promising YaMZ-536 engine (diesel in-line six-cylinder with a capacity of 312 hp), further strengthening of ballistic and mine protection, the use of remotely controlled weapons and special equipment, and improved ergonomics. In June 2011, a shelling of the car was carried out, however, undermining tests have not yet been carried out.

Customers from the VV MVD showed interest in the machine (in 2013 they plan to supply them with a pilot batch of five vehicles ^[6] ), and developers also consider the Armed Forces of the Russian Federation as clients. However, the latter have already announced the upcoming purchase of similar vehicles of the Typhoon unified family ^[ 2015 ^] , which are more suitable for use by army units, by 2015.

In 2012, the Military-Industrial Company planned to begin full-fledged serial production of the car in 2014. The market capacity is estimated at 500 cars per year. The ratio of sales in the domestic and foreign markets is projected in the proportion of 50% to 50%. Among possible foreign buyers, manufacturers name Kazakhstan , Azerbaijan , Uzbekistan , countries of Africa and the Middle East ^[6] .

In 2013, the Russian Arms Expo-2013 exhibition in Nizhny Tagil presented for the first time an Ural-BB armored vehicle with a 6 × 6 wheel arrangement, designed according to the Motovoz-2 program on the terms of reference of the Main Command of the Russian Ministry of Internal Affairs based on the chassis of the Ural-4320 multi-purpose vehicle . The armored car is equipped with the Euro-4 standard YaMZ engine, has MRAP mine protection and is made with a single-volume armored body, which can accommodate up to 17 fighters with full armament. This car will become the basis for a whole family of tactical protected vehicles with a high degree of unification and different wheel formulas, including 4 × 4. ^[eight]

In 2014, it underwent a test cycle, including undermining. The prototype was destroyed.

In 2016, the third prototype was created, finalized according to the test results. It was presented at the exhibitions Army-2016, Kadex, etc.

In November 2018, all work on the project was terminated.
