Indian Masterminds Stories

Pune/New Delhi: In a major step towards defence self-reliance, the Armament Research and Development Establishment (ARDE) of DRDO is developing a new range of indigenous heavy calibre weapons. The programme includes a 12.7mm Heavy Machine Gun (HMG) and 20mm helicopter-mounted cannons, designed to strengthen India’s firepower across land and air platforms.

This development drive marks a significant leap in reducing foreign dependency and equipping the Indian armed forces with modern, indigenous armaments tailored to local operational needs.

12.7mm HMG: Versatile Ground Combat Power

The 12.7mm HMG is being developed as a multipurpose system capable of engaging light armoured vehicles, fortified positions, and low-flying aircraft. Known globally as a workhorse in ground combat, its integration will provide enhanced infantry support and air defence capability for the Indian Army.

The indigenous design will focus on reliability, ease of maintenance, and adaptability to different combat scenarios, ensuring effectiveness in India’s diverse terrains.

20mm Cannon for Rotary-Wing Platforms

Simultaneously, ARDE is developing a 20mm cannon for integration on helicopters such as HAL Dhruv, Rudra, and the Light Combat Helicopter (LCH). This new system addresses a long-standing gap in India’s rotary-wing firepower, currently dependent on imported or outdated systems.

The cannon will be optimised for close air support, anti-infantry, anti-light armour, and suppression of enemy air defence roles. Design priorities include recoil absorption, compatibility with stabilized fire control systems, and ammunition flexibility.

Indigenous Edge in Firepower Modernisation

By focusing on homegrown heavy weapons, ARDE’s initiative reflects a larger “Make in India” approach in defence manufacturing. The development of these systems will not only cut procurement costs but also allow customization to meet the specific needs of Indian forces.

Testing will be conducted under rigorous conditions, including high-altitude and harsh environments, to ensure reliability and performance.

Strategic Boost to Self-Reliance

The new heavy weapons programme represents a critical shift in India’s defence modernisation strategy. Once inducted, the 12.7mm HMG and 20mm helicopter cannons will enhance the operational independence of the Indian Army and Air Force, while reducing long-term reliance on foreign suppliers.

This effort underscores India’s growing ability to design, develop, and field advanced weapons systems, strengthening both combat capability and defence industry resilience.
