INS Kochi (D64) is the second ship of the Kolkata-class stealth guided-missile destroyers built under the code name Project 15A for the Indian Navy.

[13] For the first time, Mazagon Docks used a "pontoon assisted" launching method in collaboration with the Russian firm Baltiysky Zavod.

The missile hit its target, decommissioned minesweeper INS Alleppey (M65), with almost pinpoint accuracy during this first-ever vertical launch from the 7,500-tonne Kochi.

The ship has built with advanced stealth features which have been achieved through shaping of hull and use of radar-transparent deck fittings.

The ships undertook tactical manoeuvres, Over the Horizon Targeting, Search and Rescue and Electronic Warfare exercises, with extensive use of helicopters.

On 15 December 2023, the cargo ship MV Reun was attacked and hijacked by Somali pirates in their first attempt since 2017.

Following Indian Navy P-8I Neptune Maritime Patrol aircraft locating those ships, Kochi as well as the Spanish ship Victoria and the Japanese destroyer Akenebono immediately sailed behind them and are proceeding to Mogadishu harbour in Somalia, the estimated location of the pirates are taking the Reun.

[31][32] On 26 April 2024, INS Kochi rescued 30 persons from a Panama-flagged and Seychelles-operated oil tanker, MV Andromeda Star, which was attacked by Houthi missiles earlier (Red Sea Crisis).

An official reconnaissance was conducted by a helicopter after which the explosive ordnance disposal (EOD) reached the vessel to "residual risk assessment".
