Notes:
Taragiri (Yard 12653), the 4th Nilgiri Class ship under Project 17A, was delivered to the Indian Navy on 28 November 2025 at Mazagon Dock Shipbuilding Limited, Mumbai. It shows major progress in Aatmanirbhar Bharat (Self-reliant India) in warship construction. It revives the legacy of the old INS Taragiri (1980–2013). It was designed by the Warship Design Bureau (WDB) with high stealth, automation, survivability and firepower.

Notes:
The Indian Navy deployed INS Gharial and three other naval vessels under Operation Sagar Bandhu to provide humanitarian assistance and disaster relief to cyclone-affected regions of Sri Lanka. INS Gharial (L23) is a Magar-class amphibious warfare ship of the Indian Navy designed for transporting troops, vehicles, and equipment for amphibious operations. It is the second indigenously built Landing Ship Tank (Large), highlighting India’s growing shipbuilding capabilities. The ship was constructed by Hindustan Shipyard Limited (HSL) and Garden Reach Shipbuilders and Engineers (GRSE). INS Gharial is among the largest ships of the Indian Navy and is part of the Eastern Fleet under the Eastern Naval Command.

Notes:
Indian Naval Air Squadron (INAS) 335, named “The Ospreys”, was commissioned at INS Hansa, Goa on 17 December 2025.

Notes:
Exercise DESERT CYCLONE–II concluded at Al-Hamra Training City, Abu Dhabi, from 18–30 December. It was a joint military exercise between the Indian Army and UAE Land Forces, strengthening defence partnership and regional security. Training combined classroom instruction and field exercises, focusing on urban operations and sub-conventional operations under a United Nations mandate. Troops practiced urban combat, building clearance, IED awareness, casualty evacuation, first aid, heliborne operations, air assault missions, and platoon-level assaults. The exercise enhanced interoperability, operational synergy, and standardisation of tactics for future multinational operations.

Notes:
A rare U.S. Air Force RQ-170 “Sentinel” stealth surveillance drone was recently spotted returning to Roosevelt Roads Naval Station in eastern Puerto Rico. The drone returned after U.S. military strikes conducted overnight against targets in Venezuela. The RQ-170 Sentinel is a high-altitude, long-endurance unmanned aerial vehicle (UAV) of the United States. It was designed and manufactured by Skunk Works, a division of Lockheed Martin, for the United States Air Force (USAF). The drone is used for intelligence, surveillance, target acquisition, reconnaissance (ISTAR), and electronic warfare missions over target areas.

Notes:
Indian Army signed a ₹293 crore contract with private defence firm NIBE Limited, in collaboration with Israel, for the Suryastra rocket system. Suryastra is India’s first Made in India universal multi‑calibre rocket launcher. It is designed for precision surface‑to‑surface strikes up to a range of 300 kilometres. The system can engage multiple targets simultaneously at different ranges. It can integrate and fire multiple types of rockets from a single platform. It offers high accuracy with a strike error of less than 5 metres. It can also launch loitering munitions up to 100 kilometres, enhancing battlefield flexibility.

Notes:
Raksha Mantri Rajnath Singh commissioned ICGS Samudra Pratap, India’s first indigenously designed pollution control vessel, built by Goa Shipyard Limited (GSL), on 5th January 2026 in Goa. The ship is the largest in the Indian Coast Guard (ICG) fleet and has over 60% indigenous content, with plans to increase to 90%. It enhances the ICG’s capabilities in pollution control, firefighting, maritime safety, coastal patrol, and extended surveillance. It is equipped with advanced pollution detection systems, side-sweeping arms, skimmers, floating booms, and a pollution control lab, it can operate even in rough seas.

Notes:
In January 2026, the Indian Army created a modern warfare force named Bhairav to strengthen combat capabilities. Bhairav battalions are designed for high-speed offensive and special operations at tactical and operational levels. Around 15 Bhairav battalions have been raised, with plans to expand to 25. These units bridge the gap between Para Special Forces and regular Infantry. Bhairav units are technology-driven and capable of independent multi-domain operations.
