India is undertaking a significant maintenance and upgrade cycle for its Prithvi-II ballistic missile system, with the DRDO’s Research Centre Imarat (RCI) issuing key tenders to sustain its operational effectiveness. Even as newer solid-fuel missile systems like Pralay are being developed, the Prithvi-II continues to serve within the Strategic Forces Command, making lifecycle support and modernization essential.
At the core of this effort is a three-year Annual Maintenance Contract aimed at ensuring the missile fleet remains operational. The contract focuses on technical servicing, skilled manpower, and system-level upkeep, while separate provisions handle major component replacements. The accelerated tender schedule highlights the importance of maintaining continuous readiness for the system.
In parallel, RCI has initiated an upgrade program for the Prithvi-II(B) variant to enhance reliability and extend its service life. While details remain classified, such modifications typically involve upgrading onboard electronics, refining guidance systems, and strengthening propulsion components. Given the missile’s liquid-fuel architecture, maintaining the integrity of fuel systems and associated components is particularly critical to reduce operational risks.
The upgrades also address compatibility with modern infrastructure, including advanced mobile launchers and updated communication networks, ensuring seamless integration within India’s evolving command-and-control architecture. This approach supports a smooth transition as the country shifts toward more advanced solid-fuel missile systems.
Although the Prithvi-II’s liquid-fuel design imposes limitations such as longer launch preparation times, the current maintenance and upgrade initiatives are aimed at improving efficiency, enhancing safety protocols, and minimizing downtime. Together, these efforts ensure that the missile remains a reliable component of India’s strategic deterrence during this transitional phase.
