India's Naval Might Soars: Indigenous Stealth Frigates INS Himgiri and Udaygiri Set to Join the Fleet

A new era of naval prowess is dawning for India as the Indian Navy gears up to induct two formidable indigenous stealth frigates, INS Himgiri and INS Udaygiri, into its burgeoning fleet. Scheduled for commissioning on August 26, these state-of-the-art warships are not merely additions to the naval arsenal; they are powerful symbols of India’s unwavering commitment to self-reliance and technological excellence in defense, embodying the spirit of 'Aatmanirbhar Bharat'.

These magnificent vessels are the latest iterations of the ambitious Project 17A frigates, a follow-on series to the highly successful Project 17 (Shivalik Class) frigates.

However, Himgiri and Udaygiri arrive with significant enhancements. They boast superior stealth features, meticulously designed to minimize their radar cross-section, acoustic signatures, and infrared emissions, making them incredibly difficult for adversaries to detect. This advanced stealth capability is complemented by a suite of cutting-edge weapons and sensors, ensuring unparalleled combat readiness and situational awareness in complex maritime environments.

The design and construction of these sophisticated warships represent a monumental achievement for India’s defense industrial complex.

The entire conceptualization and detailed engineering were undertaken by the Indian Navy's own Warship Design Bureau (WDB), a testament to the nation’s growing indigenous design capabilities. The construction itself was a collaborative effort by two of India’s premier shipyards: Mazagon Dock Shipbuilders Ltd (MDL) in Mumbai and Garden Reach Shipbuilders & Engineers (GRSE) in Kolkata.

INS Himgiri, the third ship of the P17A project, was launched with much fanfare by GRSE in December 2020, showcasing rapid progress in shipbuilding. Subsequently, INS Udaygiri, the fourth ship, was launched by MDL in May 2022, further demonstrating the accelerated pace of the program.

A key innovation in the Project 17A construction is the adoption of the Integrated Construction (IC) methodology.

This advanced shipbuilding approach involves block construction, where different sections of the ship are built separately and then integrated, significantly reducing the construction timeline and enhancing efficiency. This methodology, combined with extensive indigenization of equipment and systems, means that approximately 75% of the material and equipment on these frigates is sourced from within India, further bolstering the domestic defense manufacturing ecosystem.

Once fully operational, INS Himgiri and INS Udaygiri will play crucial roles in safeguarding India's vast maritime interests, projecting power across the Indian Ocean Region, and contributing to regional stability.

Their advanced capabilities will enable them to undertake a wide range of missions, from anti-submarine warfare and anti-air warfare to surface combat and surveillance. These frigates are not just warships; they are powerful deterrents and critical enablers for India’s strategic maritime objectives.

With seven Project 17A frigates planned in total, with three already launched and others rapidly progressing, India is systematically enhancing its blue-water capabilities.

The induction of INS Himgiri and INS Udaygiri marks a pivotal moment, showcasing India's prowess in designing and building world-class warships and reinforcing its position as a responsible and capable maritime power on the global stage. This is a moment of immense national pride, as India sails confidently towards a future of robust indigenous defense.
