VPK-3927 Volk (Russian: Волк; English: Wolf) - tactical high-mobility multipurpose military armoured vehicle, manufactured by the VPK, where VPK stands for initial letters of the Voenno-Promyshlennaya Kompaniya (Russian: Военно-промышленная компания), meaning Military Industrial Company. VPK is a military division of the GAZ group. The Volk family is based on a highly modified GAZ Tigr.
The Volk was shown for the first time during the International Forum Engineering technologies 2010 (IDELF-2010) from 30 June to 4 July 2010 in Zhukovsky, Russia. Now all three produced vehicles (VPK-3927, VPK-39272, VPK-39273) are on the stage of trials.
Volk family armoured vehicles with 1.5 t and 2.5 t capacity were developed to comply with the requirements of Army and Law Enforcement units. The vehicles were designed according to global trends of security with the high level of unification with the other vehicles of the family. They are based on a modular design principle with a focus on existing and future domestic serial production.
Volk armoured vehicles family consists of three groups: armoured, unarmoured and commercial civilian cars. The first group of armoured vehicles is currently in testing phase, the other groups are under development. The group of armoured vehicles includes: basic car VPK-3927 with protected cabin and separate armoured functional back module, VPK-39271 with a whole protected functional module joint with cabin (was not shown on the exhibition); VPK-39272 vehicle to transport cargo and personnel with the ability for installation of various functional modules; VPK-39273 6x6 vehicle with protected cabin and separate functional rear module.
There are several new design solutions applied on Volk armoured vehicles family: a unified platform, independent hydro-pneumatic suspension with height adjustment, enhanced protection of cabin, engine compartment and the functional module, new diesel engine YaMZ-5347, onboard information control system (BIUS), modular design.
The conception of protection of vehicles is based on the provision of the highest ballistic and mine protection of vehicle and personnel. The design of frame-panel armour provides its assembly and dis-assembly 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 advanced engine YaMZ-5347 Euro-4. The engine has modernization reserve for power to 300 hp. Transmission and transfer gearbox provides a resource of 250 thousand km with engine power of 240 hp.
Independent hydropneumatic suspension with height adjustment allows to change the ground clearance from 250 mm to 500 mm and move off road at speed 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 power units, cabins, suspension, transmission, onboard information control system and protection features. The internal volume of the cabin is 2.4 cubic meters, the functional module of VPK-3927 vehicle - 4.7 cubic meters, VPK-39271 mono space module- 7.2 cubic meters, and the volume VPK-39273 6x6 module is 10,3 cubic meters.
Onboard information control system (BIUS) provides a control function and diagnosis of basic units and components of vehicles with a record of their parameters. The engine is controlled by 15 parameters: pressure, temperature, speed, fuel supply, cooling system, lubricating system. Transmission and tires are controlled by temperature and pressure. Hydraulic and suspension adjustment system is controlled in 24 points. Malfunction of BIUS is not connected with mobility of the vehicle.
- VPK-3927 Volk - basic vehicle with protected cabin and separate armoured functional back module
- VPK-39271 Volk - armoured vehicle with a whole protected functional module joint with cabin.
- VPK-39272 Volk - cargo and personnel transport vehicle with the ability for installation of various functional modules. This version of Volk vehicle allows to use wide variety of functional modules, such as medic, jamming, signal or logistics modules
