India’s DRDO Flight Tests Second Indigenously Developed ‘Solid Fuel Ducted Ramjet (SFDR)’ Propulsion Based Missile System

India’s Defence Research and Development Organisation (DRDO) successfully flight tested the second indigenously developed ‘Solid Fuel Ducted Ramjet (SFDR)’ propulsion based missile system from the Integrated Test Range (ITR) in Chandipur, Odisha on Feb. 8.

According to a Ministry of Defence statement, “Ground booster, separation of ground booster and Nozzle-less-booster performance were found satisfactory”.

The missile was launched 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 statement added.

The success of SFDR propulsion technology is a significant milestone and will pave the way for development of long range air-to-air missiles in the country. The country’s Defence Minister, Nirmala Sitharaman congratulated DRDO and associated team members for the stupendous mission.

The 250-kilogram SFDR missile has been under joint development with Russia since 2013. The first test of the missile was carried out in May 2018.
