The Project 17A-class frigate is a follow-on of the Project 17 Shivalik-class frigate for the Indian Navy. A total of seven ships will be built at Mazagon Dock and GRSE. The construction of the first ship is expected to start by early 2017 and is expected to be launched by 2020, after the shipyards are upgraded to incorporate modular construction techniques.
The anticipated cost for each vessel is above ₹4,000 crore (US$594 million) and the total deal is expected to be worth more than ₹6,400 crore (US$951 million). The vessel will incorporate the latest stealth features. The first ship is expected to roll out by 2022.
The experience gained in designing the Project 17 Shivalik-class frigates will be applied to the Project 17A (P17A). The Project 17A frigates will improve upon the Project 17 (P17) in terms of stealth. They will have covered mooring deck and the number of antennae on the ship will be reduced by using a multi-functional phased array (probably AESA) radar. The P17A will also feature better roll stabilisation and a discreet visual profile. The weapon platform in the P17A ships will be compact and they will be armed with the Barak 8 (missile) surface-to-air missile developed jointly by India and Israel, and the BrahMos supersonic cruise missile. The weapon systems will be flush deck mounted allowing vertical launch of missiles from under the deck. The crew complement will be reduced from the existing 257 (including 35 officers) to about 150 by using high levels of automation, which will reduce the operational costs by around 20 per cent and result in higher operational availability of the warships. The construction times will be reduced and productivity will improved by using modular integrated construction. The ship will have a displacement of 6,670 tonnes.
Four of the frigates will be constructed by Mazagon Dock Ltd in Mumbai and three by Garden Reach Shipbuilders & Engineers in Kolkata. India’s Cabinet Committee on Security (CCS) approved the proposal of Ministry of Defence (MoD) for starting the Project 17A design-cum-construction programme in September 2012. The contract was signed with the two shipyards in February 2015. Construction is expected to commence in early 2017 after a preparatory period of 24 months and the first ship is expected to be commissioned by 2023.
On 11 March 2016, the defense ministry approved a ₹13,000 crore (US$1.9 billion) weapons and sensors package for the project. The frigates will be equipped with Barak 8 (LR-SAM), BrahMos supersonic cruise missile, Ajanta electronic warfare system and Humsa-NG radar
