Context

INS Tushil, India's latest naval asset, initiated its sea trials from Russia's Baltiysk naval base on March 5, 2024.

Details

INS Tushil

• INS Tushil falls under the Talwar-class frigates category of stealth-guided missile frigates.
• The Talwar-class guided missile frigates are the improved versions of the Russian Coast Guard’s Krivak III-class frigates.
• Currently, the Indian Navy operates six of these ships while 4 more are under construction including 2 in India’s Goa shipyard.

Features

• These ships feature "stealth technology" in terms of low radar and underwater noise signatures.
• These ships are being equipped with major Indian-supplied equipment such as surface-to-surface missiles, sonar systems, surface surveillance radar, communication suites, and anti-submarine warfare systems, along with Russian surface-to-air missiles and gun mounts.
• The frigates are designed to fight submarines and warships in brown and blue waters and repel air attacks both independently and within formations.
• The displacement is 3620 tons, the length is 124.8 meters. The full speed is 30 knots, and the cruising range is 4850 miles.

The Project 11356M

• India inked an Inter-Governmental Agreement (IGA) with Russia in October 2016, solidifying plans to acquire four Admiral Grigorovich-class (Project 11356M)
• Under this pact, Russia pledged to deliver two frigates, including INS Tushil and INS Tamala, while India undertook the construction of the remaining vessels domestically, a testament to the burgeoning Indo-Russian defence partnership.
• The construction of the ships is based on the Indian Navy’s specific requirements to meet the entire spectrum of naval warfare in all three dimensions of air, surface, and sub-surface.
