Indian Navy Developments & Discussions

On 15 October 2016, the Governments of India and the Russian Federation signed an intergovernmental agreement on the construction of two Project 11356 frigates for the Indian Navy from among those initially built for the Russian Navy at the Yantar Baltic Shipyard in Kaliningrad, and on the construction of two additional subsequent Project 11356 ships in India at Goa Shipyard Limited (GSL).

On 20 November 2018, Rosoboronexport signed a contract with Goa Shipyard Limited (GSL) worth approximately $500 million to assist in the construction of two Russian Project 11356 frigates at GSL for the Indian Navy, with the Russian side transferring licenses and technologies. This contract was in addition to the contract concluded in October 2018 by Rosoboronexport worth $1.2 billion for the construction of two Project 11356 frigates for the Indian Navy in Russia at the Yantar Shipyard in Kaliningrad.

The two frigates contracted for construction at the Yantar Shipyard were initially supposed to be transferred to the Indian Navy in 2022 and 2023. In fact, under this contract, two unfinished frigates of this type were built for the Indian Navy at the Yantar Shipyard, which had been suspended from construction for the Russian Navy - the Admiral Butakov (factory number 01360), which received the Indian name Tushil, and the Admiral Istomin (factory number 01361), which received the name Tamala. The first of these frigates, F 70 Tushil, was re-launched in Kaliningrad on 28 October 2021. The ship began factory sea trials on 5 March 2024 and was delivered to the Indian Navy on 9 December 2024. The frigate Tushil arrived in India at her home base in Karwar on 14 February 2025. The second frigate, Tamala, is currently undergoing State Trials and is currently scheduled to be delivered to the Indian Navy in June 2025.

In turn, the Government of India on 25 January 2019 signed a contract with Goa Shipyard Limited (GSL) for the construction of the next two Project 11356 frigates for the Indian Navy there. The ships, which are being built with Russian assistance and with partial technology transfer from Russia, are scheduled to be delivered to the Indian Navy in June 2026 and December 2026, respectively.

The first o1742993635999.webpf the two contracted Indian frigates, Triput (Sanskrit for "arrow"), with construction number 1258, was laid down at GSL on 29 January 2021 (the first steel cutting ceremony for it took place on 20 August 2020) and was launched on 23 July 2024. The second frigate, Tavasya (the mace of the legendary warrior Bhima from the Mahabharata), with construction number 1259, was laid down at GSL on 18 June 2021 and has now been launched.

All four Project 11356 frigates ordered by India must be equipped with their own standard M7N series gas turbine main power plants manufactured by the Mykolaiv State Enterprise Scientific and Production Complex Zorya - Mashproekt (Ukraine), which are supplied to the Indian side by the State Concern Ukroboronprom. Two sets of M7N.1E power plants for ships completed for India in Kaliningrad were delivered in 2020.

Two frigates under construction in India at GSL are to receive modified M7N2 power plants, the contract for the manufacture and supply of which was signed by the Indian side with NPKG Zorya-Mashproekt in September 2021. According to the contract, the delivery dates for the first set of power plants for frigate with construction number 1258 were set for December 2022, the second set for frigate with construction number 1259 - for July 2023. However, according to known data, due to the war in Ukraine, the power plant sets from Nikolaev were not delivered on time. However, judging by the fact that the Indian side continues to build both frigates at GSL, it is confident in the supply of propulsion systems for them from Ukraine, although, apparently, the contractual deadlines for the delivery of the ships will be disrupted.

The Indian Navy has previously commissioned six Project 11356 frigates (Talwar type), the first three of which (F 40 Talwar, F 43 Trishul, F 44 Tabar) were built at the Baltic Shipyard in St. Petersburg (they were transferred to the Indian Navy in 2003-2004), and three more (F 45 Teg, F 50 Tarkash, F 51 Trikand) - at the Yantar Shipyard (they were transferred to the Indian Navy in 2012-2013). Thus, taking into account the additional four frigates under the 2016 agreement, the Indian Navy will have ten ships of this project.
 
Seems like the Talwar Batch IV Class (Triput Class) frigates will come with the following indigenized weapon/sensor set (in bold).

What will be the replacement for Kora Class corvette?

Is it NGC or NGMV.
NGMV are direct replacements of Khukri Class. Maybe NGMV(batch 2) will be replacement of Kora Class, as Kora decommissioning are still a few years away.

NGC corvettes would be around 3500 tons and are direct replacements of Brahmaputra Class Frigates sometime in the mid 2030s. Kamorta was replacement of Godavari Class Frigates if you see the timeline.

Mahe and Arnala ASW corvettes are replacements of Veer and Abhay Class.

Though some of the roles of the newer vessels have been changing with the evolving scenarios.

Veer class is ASuW specialized. Design philosophy wise there is more similarity between it and the NGMV than the Mahe (ASW-SWC) class with no onboard helicopters, SAMs and only the MR 76mm, AK 630 and AShM.

The increased tonnage and LM2500 engines in the NGMV is to make it more amenable for increased range, better handling in open seas and to act as escorts for frigates and destroyers.

Infact in the 1990s the Indian Navy messed around with LM2500 for the Veer Class but it was dropped due to cost and complexity.
In 1990, MDL cancelled a study to equip the Indian-built units with a General Electric LM2500 gas turbines and two MTU diesels due to technical difficulties.

Can someone explain why hasn't the Navy acquired LCA-N as trainer aircraft, given that we already have a severe shortage of fighter jets in the Indian Navy. Also, the fact that they are yet to procure additional AEW&C systems for the new carrier as the Kamovs are only enough for 1. They could also buy fixed wing AEW&Cs to be operated from the Andaman and Nicobar islands if not from the carriers, because we don't have any AEW&Cs in the Indian Ocean apart from those Kamov AEW variants.

Simply because carrier training is very aircraft specific, the way a rafale would land and take off from the Vikrant is very different from the way the Tejas would.

On top of that the IN already has the MiG29Ks and the Rafales, to add the complexity of the Tejas into it doesnt make sense unless the MiG is removed from the roster, and even then given the low rate of production of the Tejas' the IAF's more urgent requirements, does it make sense?

I think not, and i believe the IN thinks the same.

I wonder IN has any plan to look at "beyond" just two carriers. Would love to have some update in this regard.
This is NOT just preparing for 3rd carrier (vision), but also land-based squadron that provide a deep pocket of capacity...
