Missile Prithvi-II

The Prithvi-II is a single-stage, liquid-fuelled surface-to-surface short-range ballistic missile. Development originated under the Integrated Guided Missile Development Program, which commenced in 1983. Aerodynamic characterization was conducted at a trisonic wind tunnel facility. The system completed its first test flight in January 1996, with developmental trials concluding in 2004.

Guidance is provided by a strap-down inertial navigation system. Upgrades to this system have reduced the circular error probable. The missile incorporates countermeasures designed to deceive anti-ballistic missile defenses. Payload options comprise conventional high explosives, penetration, cluster, fragmentation, and thermobaric munitions. The platform is also configured for chemical and tactical nuclear warhead delivery. It is launched from an 8x8 transporter erector launcher.

The missile entered service with the Strategic Forces Command in 2003. It is operated by India. The system undergoes periodic user trials to maintain operational readiness, including night-time launches conducted from mobile launchers at the Integrated Test Range. Recorded events include a failed test in September 2010, followed by successful twin launches in December 2010. User training launches have continued through 2025.
