'Udaygiri', second ship of Project 17A stealth frigate delivered to Indian Navy
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 defence ministry said.
The hull of a P17A ship is geo-symmetrically larger by 4.54 per cent vis-a-vis a P17. Also, these ships are fitted with an advanced weapon and sensors suite with enhanced "sleek and stealthy" features compared to the P17 class, it said.
The weapon suite comprises a supersonic surface-to-surface missile system, a Medium-Range surface-to-air missile system, a 76 mm gun, and a combination of 30 mm and 12.7 mm rapid-fire close-in weapon systems, the ministry said in a statement.

The project is a follow-on to the Shivalik class (Project 17) frigates active in service.
'Udaygiri' is the second among the seven P17A frigates under construction at MDL, Mumbai and Garden Reach Shipbuilders and Engineers (GRSE), Kolkata. It was delivered in a record time of 37 months from the date of launch, officials said.
"The remaining five ships of the P17A class are at various stages of construction at MDL, Mumbai and GRSE, Kolkata, and would be delivered progressively by the end of 2026," the ministry said.
P17A ships have enhanced stealth features and are fitted with state-of-the-art weapons and sensors, a significant upgrade from the P17 class, the officials said.
The ships represent a "quantum leap" in the
Indian Navy
's in-house design capabilities at the Warship Design Bureau, they said.
The Navy, in a post on X, also shared some photos of 'Udaygiri'.
"In a major thrust to #AatmanirbharBharat, Udaygiri, the second warship of the Project P17A Nilgiri Class stealth frigates, designed by Warship Design Bureau of #IndianNavy, overseen by the Warship Overseeing Team (Mumbai) and built by @MazagonDockLtd, Mumbai was delivered to the Indian Navy on #01Jul 25, at Mumbai," it said.
This is a watershed moment for the Navy as 'Udaygiri' is the 100th ship designed and delivered by the Warship Design Bureau, it said.
"The warship is built with over 75% indigenous content and is equipped with #StateoftheArt weapons and sensors. Udaygiri will boost the Indian Navy's combat readiness and capability to safeguard our maritime interest in the #IndianOceanRegion," it said in the post.
According to defence ministry officials, 'Udaygiri' is a modern avatar of its predecessor, the erstwhile INS Udaygiri, which was a steam ship decommissioned on August 24, 2007, after rendering 31 years of glorious service to the nation.
The ministry said the delivery of 'Udaygiri' showcases the nation's ship design, ship construction and engineering prowess enabled by a strong industrial ecosystem supported by over 200 MSMEs.
The warship is fitted with major weapons and sensors sourced from indigenous original equipment manufacturers (OEMs).
"The newly designed ships are also being built employing the philosophy of 'Integrated Construction', which involves extensive pre-outfitting at the block stages to reduce the overall build period," it said.
The ships are configured with combined diesel or gas (CODOG) main propulsion plants, comprising a diesel engine and gas turbine, driving a controllable pitch propeller (CPP) on each shaft and a state-of-the-art integrated platform management system (IPMS), it said.
"The shipbuilding requirements of the project have led to direct employment generation for about 4,000 personnel and more than 10,000 personnel through indirect or ancillary sources," the statement said.
The positive spin-offs of the shipbuilding project included self-reliance, economic development, employment generation, growth of MSMEs and the ancillary ecosystem in the country, it added.

Stealth, Speed, Self-Reliance: INS Udaygiri Bolsters Indian Navy
On July 1, 2025, the Indian Navy received Yard 12652, also known as INS Udaygiri, the second stealth frigate under Project 17A. This advanced warship was built by Mazagon Dock Shipbuilders Limited (MDL) in Mumbai. Project 17A is an upgraded version of the earlier Shivalik-class (Project 17) frigates already serving in the Navy. INS Udaygiri is the second out of seven frigates being constructed at MDL in Mumbai and Garden Reach Shipbuilders & Engineers (GRSE) in Kolkata under this project. According to the Press Information Bureau (PIB), this delivery marks a significant boost to India's indigenous shipbuilding capabilities and naval strength. The INS Udaygiri is a powerful warship designed to handle a wide range of missions. It can operate in open seas—what experts call a 'Blue Water' environment (which means the ship can travel and operate far from the country's coast, across deep ocean waters)—and is built to face both traditional military threats and modern challenges like piracy or terrorism, especially in areas that are important to India's security at sea. This new Udaygiri carries forward the legacy of an older ship with the same name. The original INS Udaygiri was a steam-powered ship that served the Indian Navy with pride for 31 years before it was retired on August 24, 2007. The new version is a modern, high-tech upgrade—a tribute to its proud predecessor. The Project 17A (P-17A) warships are a big improvement over the earlier Project 17 class. They come with advanced stealth features that make them harder to detect and are equipped with modern weapons and sensors that boost their combat abilities. This marks a major step forward in the Indian Navy's ability to design warships on its own, thanks to the efforts of the Warship Design Bureau. These new ships are also being built using a modern method called 'Integrated Construction'. This means many parts of the ship are pre-assembled and fitted with equipment before being joined together. Doing this speeds up the overall building process. The INS Udaygiri is a great example of this success—it was handed over to the Indian Navy in just 37 months after its launch, which is a record time for a complex warship of this kind. The hull (or body) of the Project 17A warships is about 4.5% bigger than the older Project 17 ships. This slightly larger size allows for better space and stability. These new ships are also equipped with more advanced weapons and sensors, giving them stronger fighting and detection abilities. Their design has been improved to make them look sleeker and more difficult to spot, making them more effective in stealth operations than the earlier P17 class. These ships use a Combined Diesel or Gas (CODOG) propulsion system, which means they can run on either a diesel engine or a gas turbine, depending on the speed and power needed. Each engine is connected to a special type of propeller called a Controllable Pitch Propeller (CPP), which allows better control of the ship's movement. They are also equipped with a modern Integrated Platform Management System (IPMS). This advanced system helps monitor and manage all the key parts of the ship—like engines, power supply, and safety systems—making operations smoother and more efficient. The ship is equipped with a strong and modern set of weapons. It has a supersonic surface-to-surface missile system that can hit enemy ships and other targets at sea. To protect itself from threats coming from the air, it has a medium-range surface-to-air missile system that can shoot down enemy aircraft or incoming missiles. In addition, the ship has a 76 mm main gun for general-purpose firing, and a mix of 30 mm and 12.7 mm fast-firing guns. These smaller weapons are designed for close-range defence and are very effective against threats like small boats, drones, or missiles that come close to the ship. Self-Reliance In Shipbuilding And Job Creation: The delivery of INS Udaygiri is a proud example of India's growing strength in designing and building its own warships. It highlights the country's engineering skills and the solid support of a domestic defence industry. This achievement was made possible with the help of over 200 Micro, Small, and Medium Enterprises (MSMEs) working together as part of the shipbuilding process. Most of the major weapons and sensors on the ship have been made in India by local manufacturers, showing the country's commitment to Aatmanirbharta (self-reliance) and creating jobs through Indian-made technology. Boost To Jobs And Economy The construction of INS Udaygiri under Project 17A has created a big boost for employment and the economy. Around 4,000 people got direct jobs, while more than 10,000 others found work through related industries and support services. This project has brought many benefits—including self-reliance in defence, economic growth, job creation, and the expansion of MSMEs and supporting industries across the country. The work on the remaining five P-17A warships is currently ongoing at Mazagon Dock in Mumbai and GRSE in Kolkata, and all of them are expected to be completed and delivered by the end of 2026.

Shtil-1 can fire one missile in every 2 seconds, to rev up air defence of Tamal
NEW DELHI: An improved version of the Shtil missile (Shtil-1) will be the primary weapon for anti-air defence of the latest Russian-manufactured frigate INS Tamal commissioned into the Indian Navy. Describing the latest version of the missile, sources from Russia said, 'The Russian Shtil-1 shipborne, medium-range, multi-channel, vertical-launch Surface to Air Missile (SAM) system uses a fundamentally new 9M317ME missile, the latest digital technology and software.' Shtil is a 3-stage launch vehicle that uses liquid propellant. It is the first launch vehicle to successfully launch a payload into orbit from a submarine. The SAM system offers improved performance in comparison with the Shtil-1 variant with an inclined launch of missiles. 'The system provides omnidirectional collective defence of ship squadrons and convoys as well as omnidirectional individual defence of the ship carrying the system against attacks by enemy anti-ship missiles, aircraft, helicopters, boats and ships,' the sources said. What makes the missile system a robust weapon is the 'interval between missiles' launches is 2-3 seconds.' Trials of the Shtil-1 surface-to-air missile (SAM) system with 9M317ME SAMs fitted aboard the (Project 11356) frigate Tamal have been successfully completed at a Baltic Sea range before the frigate's delivery. They involved the participation of its developers from the Almaz-Antey Air and Space Defence Corporation. INS Tamal is the eighth ship that Rosoboronexport transferred to the Indian Navy. Sources term the transfer of the Russian-manufactured frigates to the Indian Navy as being 'in line with the main vector of Russian-Indian military-technical cooperation, which is evolving, firstly, on the basis of long-term contracts, and secondly, with an emphasis on localising the production of Russian equipment and weapons at Indian enterprises in accordance with the Make in India initiative.' Kashmir shipborne SAM systems Russia is modernising the older version, Kashmir shipborne SAM systems, delivered to India since the late 1990s and installed on Project 15 Delhi class destroyers.

Navy boosts capability with two new warships
The Indian Navy on Tuesday commissioned its latest stealth multirole frigate, INS Tamal, at the Yantar Shipyard in Kaliningrad, Russia in the presence of Western Naval Command chief, Vice Admiral Sanjay J Singh who said its induction marked a significant milestone in the country's maritime defence capabilities and Indo-Russian cooperation. Indian and Russian naval officers during the commissioning ceremony of Indian Navy's Russian-manufactured guided missile frigate 'INS Tamal', in Kaliningrad, Russia. (PTI) It is the last imported warship to be commissioned into service in line with the government's sharp focus on Atmanirbhar Bharat (self-reliant India) and Make-in-India initiatives. 'INS Tamal is a formidable moving fortress at sea and is designed for blue water operations across the spectrum of naval warfare in all four dimensions --- air, surface, underwater and electromagnetic,' the navy said in a statement. The frigate is expected to reach India's west coast in September and will form part of the navy's Mumbai-based Western Fleet, HT learns. Tamal is the eighth in the series of Krivak class frigates inducted from Russia over the past two decades, and will boost the country's maritime power in the Indian Ocean region. Also, the second ship of Project 17A stealth frigate class, Udaygiri, was delivered to the navy in Mumbai on Tuesday, the navy said. 'The commissioning of versatile platforms like INS Tamal enhances the Indian Navy's reach, responsiveness, and resilience. I am confident that the ship will prove its mettle as a force multiplier in our operational architecture, towards safeguarding national maritime interests and promoting maritime security,' Singh said in his address. The 3,900-tonne Tamal is part of a $2.5-billion deal with Russia for four more Krivak/Talwar class stealth frigates for the Indian Navy, two of which have been constructed at the Yantar shipyard and the remaining two will be built at Goa Shipyard Limited. The first frigate under the deal, INS Tushil, was commissioned into the navy last December at the Yantar Shipyard and reached the country in February. Tushil and Tamal are upgraded Krivak III class frigates of Project 1135.6, and six such vessels are already in service --- three Talwar class ships, built at Baltic shipyard in St Petersburg, and three follow-on Teg class ships, built at the Yantar shipyard. The latest frigates have an indigenous content of around 26%, double that of the previous Teg-class frigates. This includes contributions from 33 firms including Bharat Electronics Limited, BrahMos Aerospace (an India-Russia joint venture), and Nova Integrated Systems (a fully owned subsidiary of Tata Advanced Systems Limited). The new frigates are armed with a range of advanced weapons, including the BrahMos supersonic cruise missiles, Shtil surface-to-air missiles with enhanced range, upgraded medium-range anti-air and surface guns, optically controlled close-range rapid fire gun system, torpedoes and rockets. INS Tamal is manned by a crew of about 250 sailors and 26 officers. Udaygiri, which is likely to be commissioned into service in August, has been built at Mazagon Dock Shipbuilders Limited (MDL). It is the second among the seven P-17A frigates under construction at MDL, Mumbai and Garden Reach Shipbuilders and Engineers Ltd, Kolkata. The navy inducted the first P-17A class frigate, INS Nilgiri, on January 15, along with INS Vaghsheer, the sixth and final Kalvari-class submarine and Surat, a destroyer --- all built at MDL. It is rare for three major platforms to be commissioned on the same day. The project is a follow-on of the Shivalik class (P-17) frigates active in service. P-17A ships have enhanced stealth features and are fitted with modern weapons and sensors, a significant upgrade from the P-17 class, the navy said in another statement. 'The ships represent a quantum leap in the Indian Navy's in-house design capabilities at the Warship Design Bureau. The newly designed ships are also being built employing the philosophy of 'Integrated Construction', which involves extensive pre-outfitting at the Block stages to reduce the overall build periods. Udaygiri has been delivered to the Indian Navy, in a record time of 37 months from the date of launching,' it added.
