A modified loading tray and breech mechanism are designed to accommodate the larger bi-modular charge system (BMCS), a significant upgrade over the bag charges used by the older Bofors gun
This change contributes to the Dhanush's greater range of 38 km compared to the 27 km of the Bofors
The YIL’s metallurgists improved the metal forging process and the quality of steel used for the breech ring and other parts.
This makes the breech stronger, more durable, and better able to withstand extreme pressures and the thermal cycling of rapid fire.
Advanced Computer-Aided Design and Manufacturing (CAD/CAM) ensure the dimensional accuracy of the breech ring.
This precision is critical for maintaining the gun's firing axis, minimizing projectile dispersion, and ensuring reliability.
The breech ring is manufactured from high-grade alloy steels that are quenched and tempered for maximum strength and resilience.
This allows it to absorb the enormous firing and recoil forces without creating stress concentrations that could damage the barrel extension.
Diffusion-based surface hardening techniques, such as plasma nitriding, are applied to the breech ring's locking surfaces.
