DRDO successfully tested the indigenous SFDR long range air-to-air missile system.

Defence Research and Development Organisation (DRDO) successfully flight tested the second indigenously developed ‘Solid Fuel Ducted Ramjet (SFDR)’ propulsion based missile system from ITR, Chandipur, Odisha today. Ground booster, separation of ground booster and Nozzle-less-booster performance were found satisfactory. Missile was guided to high altitude to simulate aircraft release conditions and subsequently nozzle-less-booster was ignited. SFDR based missile accelerated to achieve ramjet Mach number successfully. The trajectory was tracked by telemetry and radar stations till touchdown. All the mission objectives have been met.

The success of Solid Fuel Ducted Ramjet (SFDR) propulsion technology is a significant milestone and will pave the way for development of long range air-to-air missiles in the country.

Unlike conventional rockets that carry propellant and oxidizer, Ramjet uses the air as an oxidizer just like a jet engine. Therefore the weight of the fuel required is eliminated.

This Indian Solid Fuel Ducted Ramjet (SFDR) will be used as variants of missiles such as the advanced version of ASTRA.

Successful test SFDR means is that India is on the verge of mastering game-changing missile technology which will enable a jet fighter like the Tejas to launch an air to air missile that will travel at between Mach 3 and Mach 7 towards a Chinese fighter likely upwards of 300 kilometers away.

The first SFDR was tested in year 2018 which was developed under a joint Indo-Russian R&D project. This test of SFDR had achieved the speed of 3 mach.

Raksha Mantri Smt Nirmala Sitharaman congratulated DRDO and associated team members for the stupendous mission.
