The Godavari-class frigates (formerly Type 16 or Project 16 frigates) are 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 are named after the Godavari River. Two ships of this class currently serve in the Indian Navy. Subsequent ships in the class, INS Ganga and INS Gomati also take their names from Indian rivers.

INS Gomati was the first Indian Navy vessel to have digital electronics in her combat data system. The ships combine Indian, Russian and Western weapons systems.[1]

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.

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.[2] INS Godavari was decommissioned on 23 December 2015, and her Barak 1 surface-to-air missile will be installed on the flagship INS Vikramaditya.[3][4]

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.[2]

For armaments, the missile and gun package of the Soviet Nanuchka-class corvette was installed on the frigate.

The keel of the lead ship INS Godavari was laid in 1977 at Mazagon Dock Limited in Bombay. She was commissioned in December 1983.

Ships of the class

Name Pennant Builder Homeport Commissioned Decommissioned Comments
Godavari F20 Mazagon Dock Ltd. Visakhapatnam 10 December 1983 23 December 2015
Ganga F22 Mazagon Dock Ltd. Visakhapatnam 30 December 1985 Scheduled to be decommissioned

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 have been retained for now.
