Indian Navy’s INS Imphal sails for maiden sea trials

Imphal, Indian Navy’s third indigenous stealth destroyer of the Project 15B class, planned to be commissioned later this year, undertook her maiden sea sortie today. The ship incorporates several niche technologies and high indigenous content and is designed in-house by the Navy’s Warship Design Bureau and constructed by Mazagon Dock Ltd. (MDL) stands proud testimony to the Indian Navy’s thrust on the national vision of ‘AatmaNirbhar Bharat’ and ‘Make in India’ initiative.

Imphal will add significantly to the Indian Navy’s combat capabilities. With the recent commissioning of her predecessor INS Mormugao in December 2022 and the fifth Project 75 submarine INS Vagir in January 2023, commencement of sea trials of Imphal is yet another important milestone in MDL’s continued contribution towards building a strong, modern and self-reliant India.
