Goa Shipyard Limited (GSL) has signed an agreement with the Indian Government to build two additional Project 1135.6 follow-on ships for the Indian Navy.

The contract is in line with an inter-governmental agreement (IGA) between India and Russia signed in October 2016 for the construction of additional Project 1135.6 follow-on ships for the Indian Navy.

The first ship under the contract is expected to be delivered in June 2026, while the second will follow in December 2026.

In a statement, the Indian Ministry of Defence said: “The ships would carry highly sophisticated and state-of-art weapon systems and sensors. To support these ships through their life cycle, the Indian Navy has put in place requisite infrastructures for training and maintenance.”

Customised to meet specific requirements of the Indian Navy, the follow-on P 1135.6 series of frigates possess advanced stealth features including a special hull design, to limit radar cross-section, low electromagnetic, infrared and underwater noise signatures.



"The ships would carry highly sophisticated and state-of-art weapon systems and sensors."

The frigates can support the entire spectrum of naval warfare, including anti-surface warfare, anti-submarine warfare, and anti-air warfare missions.

The ships are designed to operate in littoral and blue waters; both as a single unit and as part of a naval task force.

The ministry noted that the ships are being built in India as part of the government’s ‘Make in India’ initiative.

To be constructed by GSL in Goa with assistance from Russia, the frigates will become the largest number of ships of a class in service featuring indigenous equipment such as sonar system, Brahmos missile system, and combat management system.
