Shivalik Class (Project 17 A/B) & Talwar Class Frigates

MDL is building four frigates under P-17A, their first ship ‘Nilgiri’ is set to be delivered in the middle of next year (2024), and then subsequently 1 ship each year thereafter. The fourth ship under MDL will be delivered in the middle of FY28.

GRSE is building three frigates under P-17A, their first ship ‘Himgiri’ is set to be delivered around August 2025, and then subsequently 1 ship every 6 months thereafter.
 
Think he is right, if you want ABM/BMD on some NGD, the BMD system on ship needs to be ready first, tried and tested without any fault. Perhaps the 2nd stage of destroyers can have such full on capability and much higher tonnage at 13-14000 tons class. In the first stage or the whole project, I think it will be like below.
Theoretically its not much different to INS Arihant with K15 Sagarika vs S4 or higher class with K4/K5 or so. One is a technology demonstrator and another is upscaled final product in its class which can only gets stronger with each iteration.

NGD is still very far and all the required technologies will be mature by them. The naval BMD has started to take shape. We did our first firing from INS Anvesh and now we will test all sort of related technologies be it radar, missiles, UVLS. Previously, we were crawling, now we are walking and soon we will be running in terms of naval technology.

"Currently, the construction of the ships is proceeding according to the updated completion and testing schedules. Some items are slightly behind schedule (less than 6 months). Test runs of diesel generators have been carried out on the first of the frigates, preparations are underway for factory mooring tests," Rakhmanov said in a conversation with Sputnik.

The war in Ukraine has caused further delays to the delivery of two Krivak or Talwar-class stealth frigates under construction for the Indian Navy in Russia. They are now expected to be delivered by May and October 2024 respectively, according to Alexey Rakhmanov, Director-General of the United Shipbuilding Corporation of Russia.

Ok got some clarification:

MFSTAR-RA means MFSTAR - Rotational Anteena which is EL/M-2258 ALPHA (not in import ban list)

The first project using integrated construction is the ongoing construction of seven ships of the Nilgiri class stealth frigates. The technique has since being extended to make other ships. Four of the Nilgiri class warships are under construction at Mazagon Dock Shipbuilders (MDL), Mumbai, and three at the Garden Reach Shipbuilders & Engineers (GRSE), Kolkata. Both the shipbuilders are public sector enterprises under the MoD.

The Nilgiri class is a massively upgraded derivative of the Shivalik class frigates — three of these were commissioned into the Navy between 2010 and 2012. The build period of Shivalik class — from keel-laying, then launch at sea and finally to commissioning — was almost nine years for each of them.

The Shivalik class is seen as a turning point in ship-making as India started using its own steel, the DMR 249A. From then onwards, warships use the same steel. Before the DMR 249A, India had been importing steel from Russia. Now SAIL, Jindal and Essar make it.

In contrast to the Shivalik class, the first of the Nilgiri class — from keel-laying to commissioning — is expected to take about six years and six months and is targeted for commissioning in mid-2024. An official said, “As the design parameters and manufacturing process have settled down, the time taken for each ship is getting compressed.” The last four of the Nilgiri class ships are scheduled to take just about five years to make — from keel-laying to commissioning. Six of the Nilgiri class warships have been launched at sea. The Nilgiri and the Himgiri were launched in 2019 and 2020, respectively. Four warships — Udaygiri, Dunagiri, Taragiri and Vindhyagiri — have been launched at sea in the past 15 months. And the seventh and last ship, Mahendragiri, is set for launch in September — meaning five launches in just about 16 months. Six ships of the Nilgiri class are scheduled to be commissioned between 2025 and 2027.

Commodore PR Hari (retd), Chairman and Managing Director of GRSE, says, “We estimate a reduction in build period in the construction of the Nilgiri class. Reduction in manhours has been aided by the adoption of new technologies, improving efficiency.”
