The Godavari-class frigates (formerly Type 16 or Project 16 frigates) were guided-missile frigates of the Indian Navy. The Godavari class was the first significant indigenous warship design and development initiative of the Indian Navy. Its design is a modification of the Nilgiri class with a focus on indigenous content of 72%, a larger hull and updated armaments. The class and the lead ship, INS Godavari were named after the Godavari River. Subsequent ships in the class, INS Ganga and INS Gomati also took their names from Indian rivers.

INS Gomati was the first Indian Navy vessel to have digital electronics in her combat data system. The ships combined Indian, Russian and Western weapons systems. [4]

History

The concept for the Godavari class originated from the lessons learnt in the Indo-Pakistan War of 1971. There was a need for a ship unique to Indian requirements, for deploying a hybrid of indigenously-designed, as well as Russian and European weapons systems. The keel of the lead ship INS Godavari was laid in 1978 at Mazagon Dock Limited in Bombay. She was commissioned in December 1983.

One of the requirements was to deploy two Sea King helicopters from the ship. The Nilgiri-class vessels were too small for this requirement. The final design incorporated a larger hull in order to accommodate this. [5] INS Godavari was decommissioned on 23 December 2015, and her Barak 1 surface-to-air missile will be installed on the flagship INS Vikramaditya. [6] [7] INS Ganga was retired from active service on 28 May 2017, [1] and was decommissioned on 22 March 2018. [8] The last ship of its class, INS Gomati, was decommissioned on 15 May 2022 after 34 years of service. [2]

Design

Although the Directorate of Marine Engineering suggested replacing steam propulsion with gas turbines, it was decided not to do so, since Bharat Heavy Electricals Limited and Hindustan Aeronautics Limited had made heavy investments in facilities and tooling for design of steam turbines and auxiliary systems. [5]

For armaments, the missile and gun package of the Soviet Nanuchka-class corvette was installed on the frigate. Later on, when the frigates underwent their mid-life overhauls, one major change was the replacement of the AK-725 main gun with an OTO Melara 76 mm gun.

Upgrades

All three ships later underwent an extensive upgrade of weapons and sensors. These include the fitment of the Israeli Barak SAM system, and a new fire control system based on the EL/M-2221 STGR. The P-20 missiles were retained. The AK-725 main gun was also replaced by an OTO Melara 76 mm gun on each ship.
