INS Vaghsheer: Strengthening India’s Underwater Naval Power

INS Vaghsheer represents a significant milestone in India’s maritime defense capability. As one of the most advanced conventional submarines of the Indian Navy, INS Vaghsheer symbolizes technological progress, strategic deterrence, and India’s growing self-reliance in defense manufacturing. Named after the fierce sand tiger shark, the submarine reflects stealth, agility, and lethal precision beneath the ocean surface.

Built under Project 75, INS Vaghsheer is part of India’s effort to modernize its underwater fleet and secure its maritime interests in the Indian Ocean Region (IOR). The submarine strengthens India’s ability to monitor sea lanes, deter adversaries, and conduct strategic missions with enhanced efficiency.

Background: India’s Submarine Development Program

India’s naval modernization began decades ago with the aim of protecting long coastlines, maritime trade routes, and regional stability. Submarines have always been central to this strategy.

Evolution of India’s Submarine Fleet

India’s underwater fleet evolved through:

• Soviet-origin submarines (Foxtrot, Kilo class)

• German HDW submarines (Shishumar class)

• Indigenous construction under Project 75

The introduction of Kalvari-class submarines marked a major leap toward technological independence.

Project 75: The Foundation of INS Vaghsheer

INS Vaghsheer is built under Project 75, a major initiative of the Indian Navy and the Ministry of Defence.

Key Objectives of Project 75:

• Strengthen underwater warfare capabilities

• Enable indigenous construction of submarines

• Transfer advanced technology to Indian shipyards

• Enhance stealth and endurance

The project involves collaboration between Mazagon Dock Shipbuilders Limited (MDL) and Naval Group of France.

Naming and Legacy of INS Vaghsheer

The name Vaghsheer refers to the sand tiger shark, a predator known for its silent movement and sudden strike capability. The name reflects the submarine’s operational philosophy—stealth, endurance, and precision.

The Indian Navy has a tradition of naming submarines after powerful sea creatures, symbolizing dominance in underwater warfare.
