Tell about Prithvi Missile ?

The Prithvi-III is a short-range, road-mobile, ballistic missile that started development in 2000.

This model is a departure from the liquid propulsion system of the Prithvi-I and II, as it employs a two-stage, solid propellant motor.9

The longest-ranged member of the Prithvi family of missiles, it was most likely designed for use as a tactical weapon against Pakistan and China.

Sources indicate that the missile has a range of 300 to 350 km and an accuracy of 25 m CEP. The missile has a 500 to 1000 kg payload, with up to a 10 to 20 kT nuclear warhead.

It is also reported that the Prithvi-III has four fixed tail fins and uses four control fins near the nose of the missile in order to maneuver within the lower atmosphere.10

Some reports indicate that the Prithvi-III is intended to be a sea-launched ballistic missile, and is the same development program as the Dhanush missile.
