 "DRDO, air to air missile, SFDR technology from the Integrated Test Range at Chandipur")
A successful test on Friday of the technologies that go into a “solid fuel ducted ramjet” (SFDR) has propelled the Defence Research and Development Organisation (DRDO) into an exclusive group of manufacturers that can build long-range air-to-air missiles (AAM) capable of shooting down enemy aircraft hundreds of kilometres away.
The DRDO has already impressed the Indian Air Force (IAF) with its home-grown Astra medium-range AAM. The IAF is planning to equip the Tejas Mark 1A fighter with the Astra Mark 1, enabling it to strike airborne targets at ranges of 60-70 km.
The Tejas Mark 2 fighter will field the Astra Mark
