Quick Answer: DRDO stands for Defence Research and Development Organisation, India’s premier agency for military research and weapons development, working under the Ministry of Defence. Established in 1958, it develops missiles, aircraft, tanks, and other defence technology to make India self-reliant in military hardware.

What Is DRDO?

DRDO (Defence Research and Development Organisation) is the research and development wing of India’s Ministry of Defence, responsible for designing and developing weapons systems and military equipment for the Indian Armed Forces. It operates under the Department of Defence Research and Development (DDR&D).

DRDO was formed in 1958 by merging the Technical Development Establishment and the Directorate of Technical Development and Production with the Defence Science Organisation. Its headquarters, DRDO Bhawan, is located in New Delhi, and its motto is “Balasya Mulam Vigyanam” — Science is the Source of Strength.

Structure and Network

DRDO operates through a network of more than 50 laboratories spread across India, each specialising in a specific domain — missiles and strategic systems, aeronautics, armaments, combat vehicles, electronic warfare, engineering systems, life sciences, materials, and naval systems.

As of 2026, the organisation is headed by the Chairman, DRDO and Secretary, Department of Defence R&D — a position currently held by Rajesh Kumar Singh, who took additional charge as Defence Secretary in May 2026, succeeding Dr. Samir V. Kamat.

Key Achievements

DRDO’s most well-known programmes include the Agni and Prithvi missile families, the BrahMos supersonic cruise missile (developed jointly with Russia), the Tejas Light Combat Aircraft (with HAL), the Arjun Main Battle Tank, and air defence systems such as Akash and Astra.

Its most significant recent milestone is the completion of Phase-II of India’s Ballistic Missile Defence (BMD) programme. In June 2026, DRDO successfully flight-tested the AD-1 and AD-2 interceptor missiles, giving India the demonstrated capability to intercept ballistic missiles – including ICBM-class threats — at ranges up to 5,000 km. Phase-III development, involving the AD-AH and AD-AM interceptors, is already underway.

Why DRDO Matters for SSB Interview and GK

DRDO is one of the most frequently asked GK and current-affairs topics in SSB interviews, Lecturette topics, and Group Discussions, since candidates are expected to stay updated on India’s defence self-reliance (Atmanirbhar Bharat) efforts. Interviewers often ask candidates to name recent DRDO-developed systems or explain how a specific missile programme works.
