**Summary:**
On August 26, 2025, the Indian Navy will commission the advanced stealth frigates Udaygiri and Himgiri at Naval Base, Visakhapatnam. The commissioning ceremony will be presided over by the Hon'ble Raksha Mantri Shri Rajnath Singh. These Project 17A multi-mission stealth frigates represent a significant advancement in indigenous warship design and construction. This event marks the first simultaneous commissioning of two frontline surface combatants built at different shipyards, Mazagon Dock Shipbuilders Ltd. (MDL), Mumbai (Udaygiri), and Garden Reach Shipbuilders & Engineers (GRSE), Kolkata (Himgiri).
Udaygiri and Himgiri are follow-on ships to the Project 17 Shivalik class frigates, incorporating improvements in design, stealth, weapon, and sensor systems, enabling them to execute a full spectrum of maritime missions. Udaygiri is the fastest ship of her class to be delivered post-launch, a result of modular construction. The frigates are named after INS Udaygiri (F35) and INS Himgiri (F34). Designed in-house by the Indian Navy's Warship Design Bureau (WDB), Udaygiri is the 100th ship designed by the WDB.
The ships feature modern Combined Diesel or Gas (CODOG) propulsion plants, an Integrated Platform Management System, and advanced indigenous weapons and sensors, with approximately 75% indigenous content. The commissioning of Udaygiri and Himgiri will enhance the Indian Navy's combat readiness, support the "Aatmanirbhar Bharat" initiative in defence manufacturing, and strengthen India's maritime capabilities in the Indian Ocean Region. Upon commissioning, the frigates will join the Eastern Fleet.

INDIAN NAVY SET TO COMMISSION ADVANCED
STEALTH FRIGATES UDAYGIRI AND HIMGIRI
Posted On: 25 AUG 2025 11:00AM by PIB Delhi
Indian Navy is set to commission the latest state of the art Project 17A multi-mission stealth frigates Udaygiri
and Himgiri at Naval Base, Visakhapatnam, on 26 Aug 2025. The ceremony will be presided over by the
Hon’ble Raksha Mantri Shri Rajnath Singh. This will be the first occasion when two frontline surface
combatants, constructed at two different shipyards, will be commissioned simultaneously, underscoring the
growing maritime importance of India’s eastern seaboard.
Udaygiri and Himgiri are follow on ships of the Project 17 (Shivalik) class frigates. Both these
vessels incorporate significant improvements in design, stealth, weapon and sensors systems and
are capable of executing full spectrum of maritime missions in Blue Water conditions.
Udaygiri, built by Mazagon Dock Shipbuilders Ltd. (MDL), Mumbai, and Himgiri, constructed
by Garden Reach Shipbuilders & Engineers (GRSE), Kolkata, showcase the nation’s growing
shipbuilding prowess, as well as, the synergy between India’s premier defence shipyards. Udaygiri
also holds the distinction of being the fastest ship of her class to be delivered post-launch, a result
of the modular construction methodology adopted by Indian shipyards.
In keeping with the Navy’s tradition of reviving names of illustrious predecessors, both frigates are named
after earlier INS Udaygiri (F35) and INS Himgiri (F34) that served the nation with distinction for over
30 years before being decommissioned.
The commissioning of the new Udaygiri and Himgiri thus honours the legacy of their forebearers
while ushering in a new era of capability.
Both frigates were designed in-house by the Indian Navy’s Warship Design Bureau (WDB),
and notably, Udaygiri is the 100th ship designed by the WDB, marking a milestone in five
decades of indigenous warship design. The ships feature modern Combined Diesel or Gas
(CODOG) propulsion plants, state of the art Integrated Platform Management System and a suite of
advanced weapons and sensors developed by Indian manufacturers. The ships, with about 75%
indigenous content, supported by hundreds of indigenous MSMEs, align with the Government’s
vision of Aatmanirbhar Bharat in defence manufacturing.
The commissioning of Udaygiri and Himgiri will augment the Navy’s combat readiness and reaffirm
India’s resolve to achieve self-reliance in warship design and construction. Upon commissioning,
the two frigates will join the Eastern Fleet, strengthening India’s ability to safeguard its maritime
interests across the Indian Ocean Region.
