Full Specifications

Prithvi-III (Dhanush) Ship-Launched Ballistic Missile

The Prithvi-III, also known as the Dhanush (“Bow”), represents a key advancement in India’s indigenous missile capabilities as a ship-launched variant of the Prithvi family. Developed primarily for naval operations, it provides the Indian Navy with a flexible, sea-based strike option capable of engaging both land and sea targets. This surface-to-surface ballistic missile strengthens maritime domain awareness and deterrence, particularly in regional scenarios involving carrier groups or coastal assets. Its design emphasizes seaworthiness through a stabilized launch platform, allowing deployment from naval vessels even in moderate sea conditions.

Manufacturer

The Prithvi series, including Prithvi-III/Dhanush, was developed by India’s Defence Research and Development Organisation (DRDO). Production is handled by Bharat Dynamics Limited (BDL). It is a fully indigenous system, reflecting India’s push for self-reliance in strategic defense technologies.

Speed and Range

Prithvi-III is a two-stage missile (first stage solid-fuel, second liquid-fuel in some configurations) with a maximum speed in the supersonic regime during terminal phase. Operational range varies by payload: approximately 350 km with a 1,000 kg warhead, extending to 600 km with 500 kg, and up to 750 km with a 250 kg payload. It achieves these distances with reported accuracy around 25 m CEP in upgraded variants.

Cost/Price

Exact current unit costs are not publicly disclosed in detail, but historical estimates for Prithvi variants place them in the range of ₹3–8 crore (roughly $0.35–1 million USD) per missile, depending on configuration and batch size. This positions it as a relatively cost-effective tactical system compared to longer-range strategic missiles.

The missile supports multiple warhead types, including high-explosive, fragmentation, submunitions, thermobaric, and nuclear options, making it versatile for tactical battlefield or anti-ship roles. It uses strap-down inertial guidance, with potential GPS augmentation for improved precision. Launched from hydraulically stabilized ship platforms, it has undergone successful sea trials and remains operational with the Indian Navy.
