DRDO Issues RFI for Liquid Fuel Ramjet Engine Development Partners For Cruise Missiles

The Defence Research and Development Organisation (DRDO) has released a Request for Information (RFI) to select a Development-cum-Production Partner (DcPP) for the Liquid Fuel Ramjet (LFRJ) engine. This engine is expected to play a key role in supersonic cruise missiles, enhancing India's missile technology capabilities.

About the Liquid Fuel Ramjet Engine

The LFRJ engine is a type of propulsion system designed to maintain supersonic speeds for extended periods. Unlike solid-fuel systems, it uses liquid fuel, which allows for better efficiency, longer range, and sustained high-speed flight.

Such engines are particularly important for missiles like the Supersonic TARget (STAR), which is used to test air defense systems by simulating high-speed threats. The technology also has potential applications in future indigenous cruise missiles.

Why the DcPP is Important

Through the DcPP, DRDO is looking to partner with companies that have the capability to produce and develop advanced propulsion systems. This approach allows India to combine research expertise with industrial production capabilities, ensuring that missile programs are efficient, reliable, and self-reliant.

The DcPP mechanism encourages public and private sector participation, promoting innovation and strengthening the domestic defense industry.

Possible Partners

Some companies that could potentially take up the DcPP role include:

• Bharat Dynamics Limited (BDL) – experienced in missile production and systems integration.

• Bharat Electronics Limited (BEL) – skilled in electronics, avionics, and control systems.

• Adani Defence & Aerospace – emerging private sector player in aerospace and defense manufacturing.

• Larsen & Toubro (L&T) – known for large-scale defense projects and manufacturing expertise.

These companies have the infrastructure, technical expertise, and experience needed to contribute to the development and production of LFRJ engines.

The development of a liquid fuel ramjet engine marks an important step in India’s journey toward indigenous missile technology. With the DcPP model, DRDO aims to accelerate production while ensuring that advanced propulsion technologies remain within domestic control.

By achieving this, India can expect better training capabilities, improved defense readiness, and a stronger domestic defense industrial base.
