The VPK-3927 Volk (; English: "Wolf") is a Russian 4×4 multipurpose military armoured vehicle, manufactured by Military Industrial Company. The Volk family developed modifying a previous model by Military Industrial Company, the Tigr. History The Volk debuted during the International Forum Engineering Technologies 2010 (IDELF-2010) from 30 June to 4 July 2010 in Zhukovsky, Russia. The first 20 vehicles were delivered in 2022. Volk-produced armoured vehicles with 1.5-ton and 2.5-ton capacities were developed to comply with the needs of the Russian military and police. They incorporate modular design principles as to assist with existing and future domestic serial production. Volk's armoured vehicles family consists of three groups: armoured, unarmoured and commercial civilian cars. The first group of armoured vehicles is currently in the testing phase, the other groups are under development. The group of armoured vehicles includes the basic VPK-3927 which consists of a protected cabin and separate armoured functional back module, the VPK-39271 which has a whole protected functional module joint with cabin, the VPK-39272 which is designed to transport cargo and personnel with the ability for installation of various functional modules, and the VPK-39273 6x6 vehicle which has a protected cabin and separate functional rear module. Design There are several new designs applied on Volk armoured vehicles: a unified platform, independent hydro-pneumatic suspension with height adjustment, enhanced protection of cabin, a new diesel engine YaMZ-5347, onboard information control system (BIUS), and a modular design. The conception of protection for vehicles is based on the provision of the highest ballistic and mine protection of vehicles and personnel. The design of frame-panel armour provides its assembly and disassembly in field conditions without the use of special tools. Ballistic protection is STANAG 4569 level 3 with the possibility of increasing the level. Mine protection is 1 level (2 after upgrade). Volk vehicles have the advanced diesel engine YaMZ-5347 Euro-4. The engine has modernization reserve for power up to 300 hp. The transmission and transfer gearbox provides a resource of 250 thousand km with engine power of 240 hp. Independent hydropneumatic suspension with height adjustment allows the driver to change the ground clearance from 250mm to 500mm and move off-road at speeds of up to 55–60 km/h. The angle of the front and rear overhang varies depending on the position of the suspension from 45 to 55 degrees. The minimum turn radius is 7 m. The unification of the vehicles includes unified
