The Relationship Between India's ISRO and DRDO: Technology Sharing and Missiles

India's space and defense sectors have always been at the forefront of technological innovation, with ISRO excelling in space research and development, and DRDO focusing on missile and defense systems. This article explores the relationship between these two key organizations, especially in the context of India's quest to build Intercontinental Ballistic Missiles (ICBMs).

From ISRO to DRDO: Technology Transfer and Missiles

Indian Space Research Organization (ISRO) has come a long way from its humble beginnings. The organization, initially focused on Satellite Launch Vehicle (SLV) technology, has progressed to its current form through the successful launches of the Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV). One notable achievement under ISRO’s leadership was the launch of the Rohini satellite in 1980, which marked a significant milestone in India’s space exploration capabilities.

The success of the Rohini satellite program led to the transfer of mission director Dr. A. P. J. AbdulKalam to DRDO (Defence Research and Development Organization). Dr. Kalam, who is well-known as the missile man of India, played a pivotal role in the development of the Prithvi and Agni missiles. This move was not just a transfer of manpower but a strategic shift in the focus towards missile development. Dr. Kalam’s extensive experience with satellite launch vehicles proved invaluable in the Guided Missile Development Programme (GMDP) at DRDO.

Thus, the technology transfer from space launch vehicles to guided missiles is not just a theoretical concept but a well-documented historical fact. In "Agni Siragugal," a Tamil translation of Dr. Kalam's autobiography "Wings of Fire," the process and significance of technology transfer from ISRO to DRDO are clearly explained.

Ballistic Missiles vs. Satellite Launch Vehicles

It is essential to understand that ballistic missiles and satellite launch vehicles are fundamentally different in their design, function, and operational requirements. ISRO's primary focus has been on space technology, while DRDO has been developing missiles and defense capabilities.

Satellite Launch Vehicles like the Polar Satellite Launch Vehicle (PSLV) are designed to send payloads into space. These rockets are launched from a specific site, travel through space to place satellites into their designated orbits, and then fall into the ocean or burn up in the atmosphere due to air drag. Their primary function is to work in space and place satellites into their orbits.

In contrast, Ballistic Missiles are launched from various locations, travel through space, and then re-enter the Earth's atmosphere to target their designated areas. They operate in a different environment and have different objectives. Missile defense systems, like the MIRV (Multiple Independently targetable Re-entry Vehicle), are an extension of this technology and involve multiple warheads aimed at different targets. These systems are significantly more complex and sophisticated than satellite launch vehicles.

Current Status and Future Plans

While ISRO and DRDO operate independently, there is no denying that they share a historic relationship. ISRO has contributed to missile technology through the development of guidance systems and propulsion systems, which are crucial for missile programs. In recent years, DRDO has made significant strides in missile development. Notably, the AGNI-V ICBM has been deployed, and it is equipped with MIRV technology. Further, DRDO is working on the AGNI-VI, which is designed to be a MIRV-capable missile by default.

Does this mean that ISRO and DRDO do not share technology? No, they do, but the sharing is driven by a strategic and focused approach. ISRO retains its focus on space technology, while DRDO steadily progresses in missile development. This separation of responsibilities ensures specialized expertise and focused development in their respective domains.

Conclusion

India's space and defense sectors, through ISRO and DRDO, represent a perfect blend of technological innovation and strategic focus. The technological transfers from ISRO to DRDO are not new and have been harnessed to develop missiles, with the AGNI-V and AGNI-VI serving as testament to this collaboration. Whether in developing satellite launch vehicles or ballistic missiles, each organization plays a crucial role in advancing India's technological frontiers, contributing to both space exploration and national defense.
