MIL was incorporated in August 2021 and began business on 1 October 2021, when the Indian Ministry of Defence transferred Ordnance Factory Board ammunition and explosives units into new Defence Public Sector Undertakings. Government transfer orders assigned Ammunition Factory Khadki as MIL's registered and corporate office and listed twelve production units under the company, including Khadki, Aruvankadu, Bhandara, Bolangir, Chanda, Dehu Road, Itarsi, Khamaria, Nalanda, Varangaon, High Explosive Factory Khadki, and High Energy Projectile Factory Tiruchirappalli.
The company describes its role as production, testing, research and development, and marketing of ammunition and explosives for the Army, Navy, Air Force, paramilitary forces, and police forces. Its 2023-24 annual report says MIL's factories provide an integrated production base for small, medium, and high-calibre ammunition, mortars, rockets, hand grenades, initiatory compositions, propellants, and high explosives.

MIL is a recently corporatized Indian government defense manufacturer that inherited production units from the Ordnance Factory Board. Public sources are strongest for company structure, production-unit allocation, broad product families, and selected product pages; conflict-use claims remain on individual weapon records.
