Kalyani Strategic Systems, a subsidiary of Indian defence manufacturer Bharat Forge, has unveiled the 155 mm Mobile Artillery Gun (MArG) 45 at the International Defence Exhibition & Conference (IDEX) 2025 held in Abu Dhabi from 17 to 21 February. Following the development of the MArG 39, the 45 is indicative of a longer 45 calibre gun – extending the combat range of the system.

The MArG 45 is crewed by up to six personnel, seated in a two plus four configuration in an armoured cabin at the front of the vehicle. The driver and commander are seated facing forwards, while the rear four personnel are seated back to back with a pair on either side of the cabin. When the vehicle is stationary and needs to become combat-capable, a large stabiliser mounted to the rear of the vehicle is lowered onto the ground. This primarily dissipates the significant forces that are transferred onto the vehicle as the gun recoils and also provides a platform for the loader and space for housing a spare wheel.
