The Defence Research and Development Organisation (DRDO) has unveiled the Advanced Hydro-Gas Suspension Unit (AHSU) for the Arjun Mk.1A main battle tank (MBT). This new technology represents a significant upgrade from the existing Hydro-Pneumatic Suspension Unit (HSU) used in the Arjun Mk.I.

The AHSU is a trailing arm-type suspension system specifically designed for the Arjun Mk.1A. It incorporates a gas spring and an integrated hydraulic damper, offering several advantages over the previous HSU.

Improved Capabilities

  • Enhanced off-road mobility: The AHSU is designed to provide the Arjun Mk.1A with superior high-speed cross-country manoeuvrability. This allows for faster movement on rough terrain, increasing the tank’s overall tactical effectiveness.
  • Stable firing platform: The AHSU’s design ensures a more stable firing platform, even when the tank is on the move. This translates to a higher first-hit probability against moving targets, a crucial factor in modern tank warfare.

The Arjun MBT series is already known for its excellent ride comfort due to its hydro-pneumatic suspension. The AHSU promises to maintain this advantage while offering additional benefits.

While hydro-pneumatic suspensions like the AHSU offer superior performance, they are generally more complex and expensive to maintain compared to simpler torsion bar systems used in many tanks. The DRDO’s development efforts likely aim to strike a balance between affordability and maintaining Arjun’s leading-edge capabilities.

The Arjun Mk.1A, with its increased Armour and additional features, carries a heavier weight than the Mk.I. The AHSU is specifically designed to accommodate this additional weight and can reportedly support tanks weighing up to 70 tons. This future-proofs the suspension system for potential upgrades to the Arjun platform.
