  • The second indigenously developed "Solid Fuel Ducted Ramjet (SFDR)" propulsion-based missile system was successfully flight tested in Odisha by the DRDO.
  • Unlike conventional rockets that carry propellant and oxidizer, Ramjet uses the air as an oxidizer just like a jet engine, and hence, the weight of the fuel required is eliminated.
  • With it, India can have fastest long-range missiles in two categories, providing full-fledged and multi-layered aerial protection from hostile attacks.
  • Its successful use in missiles will mark India’s entry into select club of nations that use next-generation missile technology against manoeuvring targets, compromising effectiveness of conventional missiles.
  • First flight of SFDR, developed under a joint Indo-Russian R&D project, was tested in 2018.
  • The Indian SFDR will be used as variants of missiles such as the advanced version of ASTRA.
