The Indian Army is reportedly planning to acquire additional Excalibur precision-guided ammunition for M-777 Ultra-Light Howitzer guns from the US. In July 2020, in the wake of escalating tension with China in light of hostile Chinese posturing, particularly on the border between the Union Territory of Ladakh and Chinese-occupied Tibet, further purchases of Excalibur shells were announced by the Indian Ministry of Defence. Under fast track procedures, the Indian Armed Forces have received financial support of up to $66.23m to acquire the required weapon systems.

The M777 howitzer is a towed 155 mm artillery piece. It is used by the ground forces of Australia, Canada, India, Saudi Arabia, and the United States. The M777 is manufactured by BAE Systems’ Global Combat Systems division. Under the agreement, BAE Systems supplied 25 ready-built howitzers, while 120 guns were manufactured in India by Mahindra Defence Systems Limited. A total of 7 artillery regiments are planned, each of 18 guns. The first regiment is planned to be raised by end-2020 with 15 guns supplied by BAE systems and three guns supplied by Mahindra Defense Systems Limited.
