Name
IRM Zhuk Russian Amphibious Engineer Reconnaissance Vehicle
Designation
IRM Zhuk
Alternate Designation

Equipment Type
Armored Reconnaissance Vehicle
Manufacturer
Uralvagonzavod
Date of Introduction
1980
Description
The IRM Zhuk Russian Engineer Reconnaissance Vehicle conducts reconnaissance of routes, fords, water barriers (velocity, depth, underwater obstacles, and bottom profile and density), ice, mapping, and overall terrain trafficability. Its chassis employs components of the BMP-1 IFV. It has two propellers on the rear of the hull for propulsion in the water. A wave deflector covers the front of the hull. The IRM has an emergency extraction/self-recovery system available which allows the vehicle to quickly extract itself when stuck in the mud, etc. without having the crew exit the vehicle. The system consists of two racks of 12 rockets each mounted on the rear deck between the propellers. This rocket propulsion system is especially valuable if the vehicle is stuck when under enemy fire.

Navigation System
TNA-3 inertial land navigation system
Mine Detection
RShM-2 mine detection system, plus RVM-2M, IMP-2 and RVM-2 hand-held mine detectors.The RShM-2 river-type wide-span mine detector can detect ferromagnetic materials at a depth of up to 300 mm with the vehicle moving at speeds of 3 to 5 km/h.
Echo-Sounding
an EIR echo-sounder providing an accurate determination of water depth from 0.5 to 20 m
Aiming Circle
PAB-2M aiming circle
Engineer Reconnaissance Periscope
PIR-451 retractable engineer reconnaissance periscope 1.5 m long (of which 0.75 m can be raised) and a DSP-30 rangefinder to carry out basic survey operations from within the vehicle.
Note
According to Russian sources, the IRM can carry out land route reconnaissance at a typical speed of 8 to 10 km/h and mine fields at the rate of 5 km/h. A water barrier 100 m wide can be covered in five minutes.

Amphibious
The vehicle is fully amphibious and, when travelling, the hull superstructure may carry a folded-down snorkel mast approximately 10 m long which is erected when the vehicle operates fully submerged; this mast is not always carried. When floating, the vehicle is driven and steered by two three-bladed, cowled propellers mounted one either side at the rear. A trim vane is fitted at the front of the vehicle and this is extended prior to amphibious operations.
