Visakhapatnam-class destroyer The Visakhapatnam-class destroyer is an Indian Navy guided-missile destroyer class, designed and built under the Project 15B program by Mazagon Dock Shipbuilders Limited with design inputs from Warship Design Bureau and DRDO-linked laboratories. Serving as an evolution of Delhi-class destroyer lineage and influenced by lessons from Kolkata-class destroyer, the class integrates indigenous Bharat Electronics Limited sensors, Bharat Heavy Electricals Limited auxiliaries and imported propulsion systems to enhance blue-water Indian Ocean combat capabilities, force projection, and carrier strike-group escort roles.
The class originated from Project 15B, a follow-on to Project 15A and Project 15, with naval architecture led by the Warship Design Bureau and detailed systems integration by Mazagon Dock Shipbuilders Limited. Designers prioritized stealth features tested against protocols from Bureau Veritas and modeled using computational fluid dynamics tools common in Indian Institute of Technology Madras collaborations. Structural choices reflect survivability doctrines promulgated after analysis of Operation Trident and lessons from contemporary destroyer programs such as Type 45 destroyer and Arleigh Burke-class destroyer. Procurement of sensors and weapons was influenced by procurement frameworks overseen by Defence Research and Development Organisation and approvals from Ministry of Defence (India), while project financing and audits involved Comptroller and Auditor General of India reviews.
Displacing about 7,300–7,700 tonnes and measuring roughly 163 meters in length with a beam near 17.4 meters, the class accommodates a crew of approximately 300 including aircrew for embarked helicopters from Shetland-class-type complements and HAL rotorcraft like the HAL Dhruv and Westland Sea King replacements. Command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) suites integrate systems from Bharat Electronics Limited, Electronics Corporation of India Limited, and interfaces influenced by standards used by NATO-aligned task forces. Habitability, damage-control systems and automation borrow concepts validated on INS Kolkata and incorporate maintenance practices from Mazagon Dock Shipbuilders Limited’s experience building frigates for Royal Navy-standard exports.
Weapons fit includes a long-range vertical launch system derived from Barak 8 integration, multi-role surface-to-air missiles comparable to S-350 Vityaz roles, anti-ship missiles analogous to BrahMos systems co-developed with NPO Mashinostroyenia-associated partners, and an indigenous 76 mm or 127 mm main gun influenced by designs fielded on INS Delhi. Close-in weapon systems include systems comparable to AK-630 or adaptations of Barak 1-style point defense managed alongside radar tracking from BEL and Thomson-CSF-heritage signal processors. Anti-submarine warfare armament comprises torpedo launchers and rocket-propelled depth charges integrated with hull-mounted and towed arrays similar to systems from Atlas Elektronik and sensors supplied by DRDO laboratories. Electronic warfare and decoy suites utilize indigenous developments coordinated with Defence Electronics Research Laboratory and export-technology partners.
Propulsion uses a Combined Gas and Gas (COGAG) arrangement with gas turbines procured from foreign manufacturers similar to those used in Type 45 destroyer and Arleigh Burke-class destroyer programs, coupled to controllable pitch propellers enabling speeds in excess of 30 knots and cruising ranges suitable for Indian Navy blue-water operations. Power-generation and electrical distribution systems reflect industrial cooperation with Bharat Heavy Electricals Limited and ABB-type suppliers, while onboard automation reduces crew workload following precedents set by Kolkata-class destroyer engineering. Damage control and redundancy follow classification standards from Lloyd's Register and Det Norske Veritas influenced certification practices.
Keel-laying and construction took place at Mazagon Dock Shipbuilders Limited’s Mumbai yard with the lead ship laid down in 2013, launched in 2015 and commissioned into the Indian Navy in 2021 as INS Visakhapatnam. Subsequent units—constructed under phased schedules—entered trials and commissioning following sea trials monitored by Indian Navy’s Instructional Naval Units and overseen by the Ministry of Defence (India). Construction timelines were influenced by supply-chain interactions with vendors in Israel Aerospace Industries, Russia, France and domestic suppliers including Bharat Electronics Limited and Garden Reach Shipbuilders & Engineers for component subcontracting. Ceremonial commissioning involved officials from Naval Headquarters (India) and state dignitaries marking force modernization milestones.
Ships of the class have participated in carrier escort duties alongside INS Vikramaditya and task groups during deployments across the Indian Ocean Region and into the South China Sea under combined exercises with navies such as United States Navy, Royal Navy, Japan Maritime Self-Defense Force, and French Navy during Malabar Exercise and bilateral exercises. Port calls and goodwill visits have involved interactions with authorities in Sri Lanka, Seychelles, Mauritius, and Thailand to advance maritime partnerships and logistics cooperation. Anti-piracy patrols, humanitarian assistance and disaster relief exercises referenced doctrines from Operation Raahat and interoperability trials with United States Pacific Fleet elements.
Proposals for exports have been discussed with friendly navies and shipbuilders in forums involving Defence Acquisition Council consultations and trade engagements similar to past dialogues over Project 17A platforms. Potential variants could emphasize enhanced air-defence packages akin to Type 45 destroyer upgrades or increased anti-submarine warfare specialization drawing on systems from Thales and Saab partnerships. Planned mid-life upgrades target integration of next-generation surface-to-air missiles, directed-energy weapons trials inspired by US Navy experiments, and advanced electronic warfare suites developed by DRDO and Bharat Electronics Limited to maintain relevance against peer platforms through the 2040s.
