Context: A successful training launch of a Short-Range Ballistic Missile, Prithvi-II was carried out from the Integrated Test Range, Chandipur off the coast of Odisha
- Prithvi is a tactical surface-to-surface short-range ballistic missile (SRBM) developed by Defence Research and Development Organisation (DRDO) of India under the Integrated Guided Missile Development Program (IGMDP).
- It is deployed by India's Strategic Forces Command.
- The Prithvi missile project encompassed developing three variants for use by the Indian Army, Indian Air Force and the Indian Navy.
- The initial project framework of the Integrated Guided Missile Development Program outlines the variants in the following manner:
- Prithvi I (SS-150) – Army version (150 km) range with a payload of 1,000 kg
- Prithvi II (SS-250) – Air Force version (350 km) range with a payload of 500 kg
- Prithvi III (SS-350) – Naval version (350 km) range with a payload of 1,000 kg
- Prithvi I class is a single-stage liquid-fueled surface-to-surface ballistic missile having a maximum warhead mounting capability of 1,000 kg, with a range of 150 km
- This class of Prithvi missile was inducted into the Indian Army in 1994
- Prithvi II class is also a single-stage liquid-fueled missile having a maximum warhead mounting capability of 500 kg, but with an extended range of 250 km
- It was developed with the Indian Air Force being the primary user.
- It was first test-fired on 27 January 1996 and the development stages were completed in 2004.
- This variant has been inducted into the army as well.
- Prithvi III class is a two-stage surface-to-surface missile.
- The first stage is solid fueled. The second stage is liquid-fueled.
- Prithvi III was first tested in 2000 from INS Subhadra, a Sukanya-class patrol vessel.
- Dhanush is a variant of the surface-to-surface or ship-to-ship Prithvi III missile, which has been developed for the Indian Navy.
- It is capable of carrying both conventional as well as nuclear warheads with pay-load capacity of 500 kg-1000 kg and can strike targets in the range of 350 km.
- Dhanush is a system consisting of a stabilization platform and the missile.
- It is a customized version of the Prithvi and is certified for sea worthiness.
- Dhanush has to be launched from a hydraulically stabilized launch pad.
- Its low range acts against it and thus it is seen as a weapon either to be used to destroy an aircraft carrier or an enemy port.
- The missile has been tested from surface ships of the navy many times.
