Commissioning of INS Imphal: Unveiling the Capabilities and Strategic Importance of Visakhapatnam Class Destroyers

Project 15B: Evolution and Progression

• The Indian Navy’s latest addition, INS Imphal, marks a significant milestone as the third vessel of the Visakhapatnam class of stealth-guided missile destroyers. These vessels, part of Project 15B, signify a leap forward from their predecessors—the Kolkata and Delhi classes—in terms of development, technological advancements, and strategic significance.

Project 15A vs. 15B:

• Initially commissioned between 1997 and 2001, the Delhi class preceded the 15A project, which introduced three guided missile destroyers: INS Kolkata, INS Kochi, and INS Chennai. The subsequent 15B project led to the construction of the Visakhapatnam class, representing an advanced iteration of its predecessors.

Construction and Milestones of INS Imphal

• The meticulous construction process of INS Imphal, from its keel laying to its maiden sea trials and subsequent delivery on October 20, has set records for efficiency and speed within the realm of indigenous destroyer production.
• Keel Laying: Commenced on May 17, 2017
• Launch into Water: April 20, 2019
• Sea Trials and Delivery: Maiden voyage on April 28, followed by comprehensive sea and harbor trials leading to delivery in just six months
• Commissioning: Set for December 26, signifying its entry into active naval service

Technological Advancements and Armament

• The Visakhapatnam-class destroyers boast impressive specifications, including a length of 163 meters, a width of 17.4 meters, and a displacement of 7,400 tonnes. With a combined gas and gas (COGAG) configuration integrating four gas turbines, these vessels can achieve speeds of up to 30 knots and cover a maximum range of 4000 nautical miles.
• These ships accommodate around 350 personnel, featuring enhanced ergonomics and habitability compared to earlier destroyer classes. Noteworthy technological enhancements include multiple fire zones, advanced battle damage control systems, and a total atmospheric control system (TACS) providing defense against chemical, biological, and nuclear threats.

Arsenal and Strategic Role

• The armament of the Visakhapatnam class is robust, including BrahMos surface-to-surface cruise missiles, vertically launched Barak-8 surface-to-air missiles, a 127 mm main gun on the forward bow deck, AK-630 30mm guns for close-point engagement, indigenously developed torpedo launchers, and RBU-6000 anti-submarine rocket launchers.
• Strategically, these guided missile destroyers play a pivotal role in naval formations, safeguarding fleets and carrier battle groups from various threats across surface, air, and sub-surface domains. Their incorporation of stealth features and indigenous components gives them a tactical advantage, enabling independent offensive operations and participation in network-centric warfare scenarios.

INS Imphal: A Tribute and Significance

• The commissioning of INS Imphal pays homage to the city’s historical contributions to India’s freedom struggle, underscoring Manipur’s role in pivotal events during the Anglo-Manipur War, World War II, and more. This commissioning symbolizes the importance of the North-eastern region in bolstering national security, sovereignty, and prosperity.

Conclusion

• The commissioning of INS Imphal stands as a testament to India’s stride in naval prowess, marking a significant addition to the Visakhapatnam class of destroyers. With their cutting-edge technology, formidable arsenal, and strategic significance, these vessels represent a crucial asset in safeguarding the nation’s maritime interests and security.
