New Delhi: India is taking another step towards strengthening its advanced missile technology. The Ministry of Defence has floated a tender for 500 scramjet propulsion systems intended for India’s hypersonic missile programme, according to a report published on October 19, 2026.
The tender, listed under reference number IA-01123018861, highlights India’s growing focus on advanced propulsion technology, domestic defence manufacturing, and next-generation strike capabilities. However, the tender announcement does not mean that all 500 systems have been manufactured, delivered, or inducted into military service.
India Pushes Ahead With Advanced Scramjet Propulsion System
The reported tender reflects India’s efforts to develop advanced propulsion systems that can support missiles travelling at hypersonic speeds. These systems could play an important role in future missile programmes that require high speed and sustained flight.

Hypersonic weapons generally travel at speeds above Mach 5, which is more than five times the speed of sound. Their development requires advanced engineering, heat-resistant materials, reliable propulsion systems, and sophisticated guidance technology.
India has been investing in these areas through its Defence Research and Development Organisation (DRDO). The organisation works on missile systems, scramjet propulsion, navigation, guidance, and other technologies needed for advanced weapons.
What Is A Scramjet Propulsion System
A scramjet is an advanced air-breathing engine designed to operate at extremely high speeds. The word scramjet stands for Supersonic Combustion Ramjet.
Unlike conventional rocket engines, which carry their own oxidiser, a scramjet uses oxygen from the surrounding atmosphere to burn fuel during flight. This can reduce the amount of oxidiser that a missile needs to carry.
A scramjet allows combustion to take place while air continues moving through the engine at supersonic speeds. This makes it suitable for research into high-speed flight and future hypersonic cruise missiles. However, scramjet engines cannot operate efficiently from a standstill. They need to reach suitable speeds before the engine can work effectively, which makes the launch and acceleration stages especially important.
Why Is Scramjet Propulsion System Important For India
Scramjet technology could help India develop missiles capable of maintaining extremely high speeds over sustained periods. This is important because achieving hypersonic speed and maintaining it throughout a flight are two different engineering challenges.
At very high speeds, an engine must manage intense heat, pressure, airflow, and fuel combustion. Even small design problems can affect the performance and reliability of the entire system.
Developing these technologies domestically could also reduce dependence on foreign suppliers for critical defence components. It may create opportunities for Indian companies working in aerospace engineering, advanced materials, precision manufacturing, and testing equipment.

FAQs
A scramjet is an air-breathing engine that burns fuel while air flows through it at supersonic speeds. It uses oxygen from the atmosphere rather than carrying all the required oxidiser onboard, making it a potential propulsion option for hypersonic vehicles.
According to the report, the tender is intended to support India’s hypersonic missile programme. Scramjet propulsion technology is designed to enable high-speed atmospheric flight and could support the development of future hypersonic cruise missiles.
No. A tender for propulsion systems is not the same as the deployment of operational missiles. Supplier selection, manufacturing, testing, integration, and other stages may still be required before any resulting system becomes operational.
