The Agni-4, a surface-to-surface missile developed by the DRDO(Defence Research and Development Organisation), was successfully tested from the Integrated Test Range (ITR) in Chandipur, Odisha, on 6 September 2024. This was the ninth test of the nuclear-capable intermediate-range ballistic missile (IRBM) Agni-4.

The test was a user test under the Strategic Forces Command. All the nuclear weapons of India are under the Strategic Forces Command. Agni IV missile, which can carry nuclear weapons, will come under the Strategic Forces Command.

Development of Agni-4 Missile

DRDO started the Agni-4 missile development programme in 2007. The missile was being developed to strengthen India’s nuclear deterrence capability against China and Pakistan.

The first test of the Agni-4 missile took place on December 10, 2010, which was a failure.

The Strategic Forces Command's first user trial took place on 2 December 2014 and was a success.

The test in September 2024 was the fifth user trial under the Strategic Forces Command.

Types of Missile based on Range

The range of surface-to-surface missiles is classified as short, medium, intermediate, and intercontinental.

There is no international consensus on categorising missiles based on their range. According to the United Nations Office of Disarmament Affairs, the most prevalent categorisation of missiles are as follows:

Short Range: Upto 1000 Km
Medium range: 1000 km to 3000 Km.
Intermediate Range Ballistic Missile: 3000-5,500 Km
Inter-Continental Ballistic Missile (ICBM): more than 5,500 Km.
