Key details about Project 15B destroyers
Project 15B
Project 15B is the latest indigenous destroyer program of the Indian Navy. It aims to build four advanced stealth guided missile destroyers.
Background
- Project 15B was approved by Defence Acquisition Council (DAC) in 2009.
- It is a follow-on of the earlier Project 15A (Kolkata class destroyers).
- The destroyers are being built by Mazagon Dock Shipbuilders Limited (MDL).
Features
The Project 15B warships have a number of potent features:
- Stealth – The design incorporates stealth features like shaping of hull and radar transparent deck fittings to make detection difficult.
- Size – With 7,400 tonnes displacement and 164m length, these are among the largest destroyers built in India.
- Armaments – The ships are equipped with advanced weaponry including BrahMos supersonic cruise missiles, Barak-8 medium-range surface-to-air missiles, torpedo tube launchers and rocket launchers.
- Sensors – Cutting-edge sensors like MF-STAR AESA radar and HUMSA-NG bow sonar are fitted for detection and tracking.
- Automation – The warships have a high level of automation through digital networks like Ship Data Network, Combat Management System etc.
Indigenous content
Around 75% of the components have been sourced indigenously, including critical weapons and sensors. This is a major step towards self-reliance in line with the ‘Atmanirbhar Bharat’ vision.
The destroyers under Project 15B
INS Visakhapatnam
The lead ship INS Visakhapatnam was commissioned in 2021. It is the most powerful and lethal destroyer to be built in India. After commissioning, it also successfully test fired an upgraded BrahMos missile.
INS Mormugao
The second ship, INS Mormugao was commissioned in December 2022. It had completed basin trials in December 2021 ahead of commissioning.
INS Imphal
INS Imphal, the third ship, delivered to the Indian Navy in October 2023, over four months ahead of schedule. It undertook maiden sea trials in April 2023. Imphal is also the first naval warship to have accommodation for women officers.
INS Surat
The fourth and final ship INS Surat was launched in May 2022 and is currently in advanced stages of outfitting.

Significance
The induction of Project 15B destroyers will significantly enhance the capabilities of the Indian Navy. With their advanced sensors, armaments and automation, these warships can undertake a wide range of naval missions.
Their versatility allows them to operate alone or as flagship of a naval task force. The stealth features also make them suitable for covert operations.
The project is a major contribution to the Make in India initiative. With most systems and components sourced domestically, it has given a boost to indigenous manufacturing. The quick construction timeline of Imphal also highlights the expertise developed by Indian shipyards.
Final Thoughts
The timely delivery and impressive performance of Project 15B destroyers showcase India’s proficiency in designing and building complex warships. The high level of indigenization is a step towards self-reliance in defence manufacturing, in line with the Aatmanirbhar Bharat vision.
With more such advanced warships planned, the Indian Navy’s capabilities will continue to grow in the coming years. Project 15B sets a benchmark for future indigenous shipbuilding projects.
