The Defence Research and Development Organization (DRDO) in India has successfully conducted the testing of a crucial propulsion technology. This technology will assist in empowering the nations next-generation aviation technology with the beyond-visual-range-air-to-air missile, Astra Mk-3, according to the sources. The missile is also called a Gandiva, which makes it one of the integral defense development assets of the Indian defense sector.
The video shared by DRDO states that Solid Fuel Dusted Ramjet (SADR) technology was successfully flight tested from the Integrated Test Range (ITR), Chandipur off the coast of Odisha today. SADR is very crucial for the development of long-range Air to Air Missiles.
According to the Precedence Research, the next-gen aircraft propulsion system market size accounted for USD 5.48 billion in 2025 and is predicted to increase from USD 6.34 billion in 2026 to approximately USD 23.37 billion by 2035, expanding at a CAGR of 15.61% from 2026 to 2035 due to the stricter regulations for reducing carbon emission, expansion of defense fleet with advance technologies amid geopolitical tensions, and rising focus on expanding military capabilities.
The DRDO tested the solid fuel-dusted Ramjet propulsion system with its integrated test range. The test was completed in Chandipur, a region of Odisha state in India. The system goes through a huge acceleration force and is given a supersonic speed with the help of a booster. After that, the Ramjet engine took over, and which sustained the thrust during the flights cruise phase.
According to the statement by the Ministry of Defense, India, all subsystems, such as nozzle-less booster, SADR motor, and fuel flow controller, performed as expected, and performance was done correctly and validated with flight data collected by tracking systems along the Bay of Ben.
A recent report by Precedence Research highlights that the next-gen aircraft propulsion system market is benefiting from the indigenous fighter engine development, increased defense spending, and urgent need for sustainable propulsion and localized manufacturing for UAVs.
