Notably, Yard 12706 (Imphal) follows in the wake of her predecessors Indian Naval Ships Visakhapatnam and Mormugao commissioned in the past two years.

Designed by the Indian Navy’s Warship Design Bureau (WDB) and built by M/s Mazagon Dock Shipbuilders Ltd, Mumbai, this ship is a hallmark of indigenous shipbuilding and is amongst the most technologically advanced warships in the world.

Being a guided missile destroyer with a displacement of 7,400 tons and an overall length of 164 meters, Imphal is a potent and versatile platform equipped with state-of-the-art weapons and sensors, including surface-to-air missiles, anti-ship missiles and torpedoes.

Powered by a Combined Gas and Gas (COGAG) propulsion set, comprising four gas turbines, she is capable of achieving speeds in excess of 30 knots (56 km/h).

The ship boasts of a high indigenous content of approximately 75% that includes Medium Range Surface-to-Air Missiles (BEL, Bangalore), BrahMos Surface-to-Surface Missiles (BrahMos Aerospace, New Delhi), Indigenous Torpedo Tube Launchers (Larsen & Toubro, Mumbai), Anti-Submarine Indigenous Rocket Launchers (Larsen & Toubro, Mumbai) and 76mm Super Rapid Gun Mount (BHEL, Haridwar).

Further, the ship is equipped with two helicopters onboard to further extend its reach. 

Additionally, the Ship boasts of a very high level of automation with sophisticated digital networks such as Gigabyte Ethernet based Ship Data Network (GESDN), Combat Management System (CMS), Automatic Power Management System (APMS) and Integrated Platform Management System (IPMS).

Imphal’s keel was laid on 19 May, 2017 and the ship was launched into water on 20 April, 2019.

The ship had sailed out for her maiden sea trials on 28 April, 2023, and, ever since, has undergone a comprehensive schedule of trials in harbour and at sea, leading up to its Delivery within a record timeframe of only six months which is more than four months ahead of the contractual time 

The time taken to build Imphal and for her trials is the shortest for any indigenous destroyer.

Worth mentioning that the indigenous content in Project 15B Class Destroyers is 72% which is a notch above their predecessors P15A (59%) and P15 (42%) Class Destroyers,
