Ordnance Factory Day 2025: History, Significance, and India's Defence Strength

Ordnance Factory Day is observed every year on March 18 to commemorate the establishment of the first Ordnance Factory in colonial India near Kolkata in 1801. This day highlights the research, development, and production capabilities of the Indian Ordnance Factories, which play a crucial role in enhancing India’s defence sector. India’s oldest Ordnance Factory, located in Cossipore, Kolkata, began its operations on March 18, 1802. In 2021, the Ordnance Factory Board (OFB) was restructured into seven Defence Public Sector Undertakings (DPSUs) to improve efficiency and self-reliance in defence manufacturing.

History of Indian Ordnance Factories

Establishment and British-Era Development

The roots of India’s Ordnance Factories trace back to 1775, when the Board of Ordnance was established in Fort William, Kolkata under British rule.
The British East India Company considered military hardware a critical element for strengthening their hold in India.
The first gunpowder factory was set up in Ishapore in 1787, with production starting in 1791.
In 1801, the Gun Carriage Agency at Cossipore, Kolkata (now known as Gun & Shell Factory, Cossipore) was established, officially commencing production on March 18, 1802.
The first-ever Ordnance Factories Day was celebrated on March 15, 1802.

Post-Independence Expansion

At the time of India’s independence in 1947, there were 18 Ordnance Factories.
Over the years, this number expanded to 41 factories, including those at Nalanda and Korwa, engaged in producing arms, ammunition, vehicles, and defence gear.
The Narendra Modi government later reclassified 275 products as non-core items, allowing their procurement from the open market, reducing dependency on ordnance factories.

Significance of Indian Ordnance Factories

Indian Ordnance Factories are often referred to as the Fourth Arm of Defence, supporting the Indian Army, Indian Air Force, and Indian Navy.
These factories play a pivotal role in the production, testing, research, logistics, and marketing of a comprehensive range of land, sea, and air defence systems.
India is ranked among the world’s most powerful nations in defence equipment, with the OFB being the 37th largest global defence producer, 2nd largest in Asia, and largest in India.

Transformation of Ordnance Factory Board (OFB) in 2021

Why Was OFB Restructured?

In October 2021, the Ordnance Factory Board (OFB) was dissolved, and its functions were transferred to seven new Defence Public Sector Undertakings (DPSUs).
The objective was to increase efficiency, competitiveness, and self-reliance in India’s defence manufacturing sector.

The Seven New Defence PSUs

DPSU	Specialization
Advanced Weapons and Equipment India Limited (AWEIL)	Small arms, rifles, and military-grade weapons
Gliders India Limited (GIL)	Parachutes and airborne defence equipment
Troop Comforts Limited (TCL)	Defence clothing, boots, and protective gear
Armoured Vehicles Nigam Limited (AVNL)	Battle tanks and armoured vehicles
Munitions India Limited (MIL)	Ammunition, explosives, and artillery shells
Yantra India Limited (YIL)	Engineering components and mechanical defence equipment
India Optel Limited (IOL)	Optics, surveillance systems, and night vision devices

India’s Defence Capabilities and the Role of Ordnance Factories

India’s Growing Defence Strength

The Indian military continues to face security challenges from China and Pakistan, necessitating constant upgrades in defence technology.
The Ordnance Factories contribute significantly to making India self-reliant in arms and ammunition production.
India exports military-grade arms, ammunition, and defence accessories to over 30 countries.
The country is aiming to be a global leader in defence manufacturing under the Atmanirbhar Bharat initiative.

Key Milestones Achieved by Ordnance Factories

Development of 12.7 mm Stabilized Remote-Controlled Gun (SRCG).
Introduction of 14.5/20 mm Anti-Material Rifle.
Indigenous production of rifles, ammunition, and battle tanks.

Objectives of the Indian Ordnance Factories

The primary objectives of the Indian Ordnance Factories include:

Production of Defence Equipment: Manufacturing arms, ammunition, tanks, and other military gear for the Indian Armed Forces.
Modernization of Production: Upgrading manufacturing processes and technology to improve quality and efficiency.
Research & Development: Investing in advanced technologies through in-house R&D and Transfer of Technology (ToT).
Customer Satisfaction & Market Expansion: Enhancing customer relations and expanding into global defence markets.
