YARD 12707 (SURAT) AND YARD 12651 (NILGIRI) DELIVERED TO INDIAN NAVY
In a historic milestone for the country's
Aatmanirbharta, journey, two warships,
a destroyer (Surat) and a frigate (Nilgiri) were delivered to the Indian Navy on
20 Dec 24. The ships have been designed and constructed
indigenously by the
Warship Design Bureau of Indian Navy and
M/s MDL, respectively. This is in keeping with the thrust, given by Government of India and the Indian Navy, on nation building through self-reliance. Simultaneous induction of two state-of-the-art men of war will significantly enhance the operational capabilities and combat readiness of the Indian Navy.
Yard 12707 (
Surat),
the fourth and final Project 15B stealth guided missile destroyer, follows in the wake of her predecessors
IN Ships
Visakhapatnam,
Mormugao and
Imphal commissioned in the past three years. The delivery of Surat culminates the iconic indigenous destroyer building project of the Indian Navy, which began with the Project 15 (three
Delhi class, 1997-2001), followed by Project 15A (three
Kolkata class, 2014-2016) and Project 15B (four
Visakhapatnam class, 2021-2024). Being a guided missile destroyer with a displacement of
7,400 tons and an overall length of
164 meters,
Surat 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 has achieved speeds in excess of
30 knots (56 km/h) during her sea trials. It is also poised to be
IN’s first Al enabled warship utilising indigenously developed Al solutions which would enhance its operational efficiency manifolds.
Yard 12651 (
Nilgiri),
the first Project 17A stealth frigate is a follow-on of the
Shivalik class (Project 17) frigates active in service.
Nilgiri is first among the seven P17A frigates under construction and MDL, Mumbai and GRSE, Kolkata. These multi-mission frigates are capable of operating in a
‘blue water’ environment dealing with both conventional and non-conventional threats in the area of India’s Maritime Interests. The newly designed ships are also being built using
‘Integrated Construction’ philosophy, which involves extensive pre-outfitting at the Block stages to reduce the overall build periods. The ships are powered by
two Combined Diesel or Gas (
CODOG) main propulsion plants, each comprising a Diesel Engine and Gas Turbine, driving a Controllable Pitch Propeller (
CPP). The ships also have state- of-the-art Integrated Platform Management System (
IPMS). The ships are fitted with supersonic surface-to-surface missile system, Medium Range Surface-to-Air Missiles system, 76 mm Upgraded Gun, and a combination of rapid-fire close-in weapon systems.
The delivery of the vessels showcases the nation's design, ship construction, engineering prowess and industrial know-how. The delivery also reinforces
IN’s unrelenting focus on
Aatmanirbharta in both ship design and shipbuilding. In keeping with the current thrust on nation building through self-reliance the vessels have
75% indigenisation content with orders on a myriad of indigenous firms including
MSMEs (more than 200 in each shipyard). The projects have boosted self-reliance, economic development, employment generation, growth of MSMEs and ancillary ecosystem in the country.
The warships are fitted with major weapons and sensors sourced from indigenous OEMs, viz M/s BAPL, L&T, MTPF, M/s BEL, BHEL, Mahindra etc
Surat's keel was laid on 07 Nov 19 and was launched on 17 May 22. The ship has been delivered to the Indian Navy in 31 months from launch to delivery, making her the fastest indigenous destroyer ever built. The ship had commenced her Contractor Sea Trials on 15 Jun 24 and completed her Final Machinery Trials on 25 Nov 24, within an unprecedented record time of just six months.
Nilgiri’s keel was laid on 28 Dec 17 and the ship was launched into water on 28 Sep 19. The ship had sailed out for her maiden sea trials in Aug 24 and ever since, has undergone a comprehensive schedule of trials in harbour and at sea, leading up to its delivery now.
The balance six ships of the class are at various stages of construction at MDL, Mumbai and GRSE, Kolkata. These ships are expected to be delivered to
IN in 2025 and 2026.
