Galerie de photos d’un IRM IPR, IPR est une variante de l’IRM « Zhuk » utilisé pour la reconnaissance des barrières d’eau. Il est équipé d’un tuba, d’un réservoir de ballast dans la section du nez, de deux grands et deux petits réservoirs de ballast et d’un réservoir à verrouillage pneumatique pour les équipements de plongée qui permettent d’effectuer une reconnaissance sous-marine à une profondeur opérationnelle maximale de 8 m et à une profondeur totale de 15 m. Il a été produit en petit nombre par le « Muromteplovoz » Usine de locomotives

The **IRM** (*Inzhenernaya Razvedyvatelnaya Mashina*, or « Engineer Reconnaissance Vehicle »), often nicknamed ** »Zhuk »** (Beetle), is a specialized Soviet-designed amphibious armored vehicle. The **IPR** (*Inzhenernyy Podvodnyy Razvedchik*, or « Engineering Underwater Reconnaissance ») is a highly specialized variant of the IRM.

Both vehicles are built upon the chassis and running gear of the widely produced **BMP-1** Infantry Fighting Vehicle, providing them with high mobility, off-road capability, and light armor protection.

Primary Mission and Function

The main role of the IRM is to perform detailed reconnaissance for combat engineer units, specifically focusing on:

• **Route Reconnaissance:** Assessing and clearing pathways for advancing forces.
• **Mine Detection:** Equipped with deployable devices to identify and mark minefields.
• **Water Obstacle Assessment:** Critically important for assessing river crossings, including:
  • Water depth and flow velocity.
  • Bottom profile and soil density (for determining trafficability).
  • Locating underwater obstacles or hazards.
• **Terrain Evaluation:** Overall mapping and determining the ability of the ground to support heavy military vehicles.

Key Design Features

• **Chassis Base:** Derived from the reliable BMP-1 chassis.
• **Mobility:** Fully tracked for high off-road performance and fully **amphibious**.
• **Water Propulsion:** Propelled in the water by **two shrouded propellers** located at the rear of the hull.
• **Self-Recovery:** Features a unique **rocket-powered self-recovery system** on the rear deck to quickly extract the vehicle when it becomes stuck in mud or soft ground.
• **Armament:** Typically features only light armament for self-defense, such as a machine gun mounted on the roof.

The IPR Submarine Variant

The **IPR** is a more complex variant of the IRM, specifically enhanced for deep-water reconnaissance, often used to check the structural integrity of bridge piers or deep river bottoms.

• **Enhanced Submergence:** Equipped with special **ballast tanks** (including in the nose section) and an advanced snorkel system to allow for full submersion.
• **Operational Depth:** Designed to operate at significantly greater depths than the standard IRM (reportedly up to 15 meters).
• **Diving Equipment:** Includes an air-locked compartment for specialized diving equipment and personnel.
