The Defense Research and Development Organisation (DRDO) is responsible for the development of technology for use by the Indian armed forces. DRDO is under the administrative control of the Ministry of Defence, Government of India. It was established in 1958.

There are many weapon systems which were largely managed by DRDO.

Ballistic Missile Defence System

The Indian Ballistic Missile Defence Programme is an initiative to develop and deploy a multi-layered ballistic missile defence system to protect from ballistic missile attacks.
The two-tiered shield should be able to intercept any incoming missile launched 5,000 kilometres away.

INSAS - Indian Small Arms System

INSAS (Indian Small Arms System) is a family of infantry arms consisting of an assault rifle and a light machine gun.

It is designed by Armament Research and Development Establishment (ARDE), Pune.

It is manufactured by the Ordnance Factories Board at Ordnance Factory Tiruchirappalli, Small Arms Factory Kanpur and Ichapore Arsenal.

INSAS has been included in the top 10 weapon systems developed by DRDO
