Russia markets new PRP-4A artillery reconnaissance vehicle

Russia's UralVagonZavod has completed its latest enhanced version of the PRP-4A reconnaissance vehicle, with enhanced capabilities.

The PRP-4A - which is based on the BMP-1 infantry fighting vehicle - has been designed to carry out reconnaissance for artillery units and act as a general forward observation vehicle. In the former role, target information is sent to an artillery battery command post vehicle, usually based on the tracked Artillery Command and Reconnaissance Vehicle in Russian service, which then initiates a fire mission with weapons such as the 152 mm 2S19 self-propelled artillery systems.

Although completed by UralVagonZavod, the actual prime contractor for the PRP-4A is Rubtsovsky Branch Research and Production Corporation.

Each PRP-4A is normally operated by a commander, reconnaissance system operator, surveyor/radio operator, and driver/mechanic. Its sensor package enables it to conduct missions around the clock, determining target co-ordinates through 360° in traverse, and +/-5° in elevation.

The sensor suite combines a suite of specialised electro-optical equipment - which can be used on board and while dismounted - and battlefield surveillance radar. It has two work stations, one for the commander and one for the reconnaissance systems operator. Both have multifunctional video monitors, a video screen, KL-85 keyboard, and controls for their individual specialised subsystems.

The radar is an IL120-1 installation, which can be retracted into the turret rear when not required. It can be operated by the commander or driver and detect a dismounted individual at a range of 7 km and a tank-sized target at 20 km.

The SOEP system sensor is located on the top of the turret with the wind sensor to the immediate rear. (Christopher F Foss)

A 1D14-1 periscopic laser rangefinder is mounted on the left of the turret roof, able to lase tank-sized objects at a maximum range of 10 km, or 20-25 km against larger objects. The device's field-of-view is limited by the turret, offering a limited traverse of 30° left and right of boresight, or 360° when the turret is traversed. The 1PN125 sensor is mounted on the right side of the turret under armour protection. It has three modes of operation, passive, active and strobe, and can be used day and night.

On the left side of the turret is a 1PN126 thermal camera - with a range measuring device - which is also under armour protection. It has a stated maximum range of 5 km with two modes of operation: detection and identification.

PRP-4A standard equipment includes 1D18 (LRP2) laser rangefinder binoculars (with a maximum range of 20 km), standard B10 x 32 binoculars, and BN-3 (1PN-94) image intensification night-vision binoculars.

Some of this equipment can be unshipped to create a dismounted observation post that can be set up 500 m from the vehicle using a wired connection, or 6 km using a VHF radio link. An R-168-5(E)-2 portable radio can be used for dedicated dismounted communications, together with a PAB-2AM aiming circle. However, a direct line provides voice transmission for short dismounted operations.

The 1T144 survey and navigation system receives information from a number of sensors and then displays the data on a flat-panel display.

Its communications package comprises one R-168-100KBE high-frequency radio, two R-168-25UE VHF radios, 1T827 vehicle intercom system, and a T-236-V data communications system. This has a maximum unrelayed range of 50 km.

The combat weight of the PRP-4A is 13.8 tonnes, and it is powered by a UTD-20S1 V-6 diesel, which develops 300 hp and propels the vehicle up to a maximum speed of 65 km/h. The vehicle is fitted with an auxiliary power unit to power the sensors with the main engine switched off.

Its armament is strictly for close-in self-defence, with a 7.62 mm PKTM machine gun and an optical-electronic suppression system (SOEP), which is connected to 14 grenade launchers arranged around the turret to provide coverage through 360°.

SOEP detects incoming laser radiation and displays this information on a monitor. The laser threat is then countered by an aerosol screen created by 81 mm 3VD35 grenades.

In addition, like the BMP-1, the PRP-4A can lay its own smoke screen by injecting diesel fuel into the exhaust outlet on the front right side of the hull. The resulting cloud will typically cover a distance of 100-150 m and persists for about one minute, weather permitting.

The vehicle is fully amphibious with little preparation and is propelled through the water by its tracks at a maximum speed of 7 km/h.

Standard equipment includes an NBC system, fire detection and suppression system, unditching beam (which is normally carried on the left side of the hull), and camouflage equipment which includes a camouflage net and set of heat shields.

??? :o Ouuuuuuulala. Mais dit donc, c’est qu’il en a une toute petite, toute rikiki roohhhh :-X O0

"This type of howitzer would best fit the needs of medium brigades with APCs, whose high share of wheeled vehicles and fairly high marching speed would warrant the addition of such an asset," he explains. "Tracked Msta-S howitzers or towed Msta-B howitzers would slow down the advance of a marching convoy within such units. On the other hand, the howitzer would prove useless for light brigades because it is too big to fit into an Mi-26 [transport helicopter], which is a mandatory parameter for light weapons [operated under the Russian military system].
