India successfully test-fired the Agni-3 intermediate-range ballistic missile on Friday, February 6, 2026, from the Integrated Test Range in Chandipur, Odisha. The Ministry of Defence (MoD) announced that the launch validated all operational and technical parameters of the missile. The test was conducted under the aegis of the Strategic Forces Command (SFC).

The Agni-3 is an intermediate-range ballistic missile (IRBM) with a strike range of 3,000 to 3,500 km and has been in service with India's SFC since 2011. This missile is a key component of the country's nuclear deterrent. The indigenously developed missile is a two-stage, solid-fuelled system capable of carrying a 1,500 kg payload. It is primarily designed as a nuclear delivery system, with an estimated warhead yield of 200–300 kilotons.

The successful test launch is part of routine user training exercises. The Agni-3's technology and operational capabilities have been validated through this launch.

India has been developing its missile capabilities, including rail-based mobile launcher systems, to enhance its strategic strike capabilities. In late December 2025, India successfully test-fired the nuclear-capable Agni-Prime missile from a rail-based mobile launcher system, referred to as the 'ghost train'. This system is difficult for enemy radars and satellites to detect because it uses India's vast railway network.

With the INS Arihant undertaking deterrence patrols, India has completed its nuclear triad and operationalized its second-strike capability. The nuclear triad consists of land-launched nuclear missiles, nuclear submarines, and aircraft with nuclear missiles, ensuring a robust and credible nuclear deterrence. A second-strike capability assures the ability to respond to a nuclear attack with a powerful nuclear retaliation.
