Apollo Micro Systems Limited (BSE: 540879 / NSE: APOLLO) has announced a strategic partnership with Dynamic Engineering and Design Incorporation, a US-based defence technology firm, to advance indigenous rocket motor development for BM-21 Grad rockets. This announcement was made on September 11, 2025, following the signing of a Memorandum of Understanding (MoU) by Apollo Strategic Technologies Private Limited (ASTPL), a subsidiary of Apollo Defence Industries Limited (ADIPL).

Key Details of the MoU

The MoU, signed at DSEI London on September 10, 2025, outlines:

• Technology transfer from the US firm to Apollo for rocket motor manufacturing.

• Co-development of BM-21 Grad ER and non-ER rocket motors.

• Potential licensed production of rocket motors within India.

This partnership aligns with the Make in India initiative, aiming to indigenize propulsion systems for multi-barrel rocket systems and strengthen self-reliance in critical defence technologies.

Strategic Significance for India

The BM-21 Grad rockets are widely used globally for area saturation and suppression missions due to their rapid-fire capability and range up to 40 km. By developing domestic rocket motors, Apollo Micro Systems will:

• Reduce import dependency for critical rocket propulsion systems.

• Lower lifecycle costs for artillery rockets.

• Enhance strategic autonomy in India’s defence manufacturing sector.

• Enable rapid scaling of production to meet both domestic and export demands.

• Support life cycle management and refurbishment of rocket systems.

Apollo Group’s Progress

Apollo Group has previously developed the 122 mm rocket warhead in-house and is preparing for immediate trials with full-scale production targeted by mid-2026. The collaboration will integrate these indigenously developed warheads with domestically produced rocket motors, marking a significant milestone in private Indian defence manufacturing.

Broader Implications

This MoU positions Apollo as one of the first private Indian companies capable of offering a fully in-house developed rocket system. Key outcomes include:

• Strengthening India’s position in the global defence supply chain.

• Advancing the Government of India’s vision of self-reliance in defence production.

• Enhancing Apollo’s capabilities in rocket systems manufacturing, contributing to strategic and technological advancement in India’s defence sector.

About Rocket Motors

The rocket motor, comprising propellant, casing, nozzle, and ignition system, is the primary propulsion subsystem for artillery rockets. It determines:

• Rocket range, stability, thrust, and accuracy.

• Production autonomy is strategically critical for national security.

Conclusion

Apollo Micro Systems’ partnership with Dynamic Engineering USA is a landmark step in India’s private defence manufacturing sector, enabling indigenization of rocket motors and integration with domestically developed warheads. The initiative reinforces India’s strategic autonomy, reduces dependency on imports, and enhances the private sector’s role in advanced defence technology production.
