Notes:
The Indian Navy deployed a P-8I maritime patrol aircraft to Guam to join the US-led Sea Dragon anti-submarine warfare (ASW) exercise 2026. The exercise includes QUAD partners: United States, India, Australia, Japan, and also New Zealand. Multiple P-8 aircraft participate, enabling better coordination due to similar systems, sensors, and data-link capabilities. The drill improves ASW skills by training crews from simulated targets to real submarine detection with 200+ flight hours. Joint classroom sessions are also conducted to refine tactics and coordination. The deployment comes as India ensures safe passage of merchant ships in the Arabian Sea for energy security.

Notes:

Notes:
India is set to receive the remaining two units of the S-400 Triumf from Russia in 2026, completing the delivery under the deal. The system was procured under a $5.43 billion agreement signed in 2018 for five squadrons, out of which three are already inducted into the Indian Air Force. The S-400 is a modern long-range surface-to-air missile (MLR SAM) system developed by Russia. It can track and destroy multiple aerial targets at once within a range of up to 600 kilometres. The S-400 provides a powerful multi-layered air defence shield against threats like fighter jets, drones, cruise missiles, ballistic missiles, and stealth aircraft.

The exercise aims to enhance regional security through joint operations and interoperability.

Notes:
India plans to equip Dassault Mirage 2000 jets with Astra Mark-2 missiles, enhancing interception up to 240 kilometres and boosting aerial dominance. Astra Mark-2 is a Beyond Visual Range (BVR) air-to-air missile, developed by the Defence Research and Development Organisation (DRDO). More than 50 industries, including Hindustan Aeronautics Limited (HAL), contributed to its development. Astra Mark-1 (90–100 kilometres range) is already inducted in the Indian Air Force (IAF) on LCA Tejas and Su-30 MKI.

Notes:
The Ministry of Defence signed contracts worth ₹975 crore to procure TRAWL assemblies for T-72 tank and T-90 tank to enhance minefield breaching capability of the Indian Army. The agreements were signed with Bharat Earth Movers Limited and Electro Pneumatics and Hydraulics (India) Private Limited in New Delhi. The TRAWL system, developed by Defence Research and Development Organisation, enables tanks to safely pass through minefields, including those with advanced anti-tank mines and magnetic fuses. The procurement falls under the Buy (Indian–Indigenously Designed, Developed and Manufactured) category, promoting domestic defence production.

Notes:
INS Nireekshak reached Colombo to participate in IN–SLN DIVEX 2026 (India–Sri Lanka Navy Diving Exercise). It is a Diving Support and Submarine Rescue Vessel of the Indian Navy. The exercise (21–27 April 2026) focuses on diving operations, training, and interoperability. It strengthens maritime cooperation between India and Sri Lanka.

Yildirimhan Missile is a prototype intercontinental ballistic missile (ICBM) unveiled by Turkey to strengthen defence self-reliance and expand its strategic military capabilities. The missile is capable of targeting regions across Europe, Africa, and Asia if launched from Turkey. Yildirimhan can reportedly travel at speeds up to Mach 25, which is nearly 25 times the speed of sound and falls under hypersonic speed range. It uses four rocket propulsion engines and is powered by liquid nitrogen tetroxide fuel, which improves range and payload capacity.

Notes:
Russia announced the deployment of the Sarmat strategic nuclear Intercontinental Ballistic Missile (ICBM), also known by the North Atlantic Treaty Organization (NATO) designation “Satan II.” It is developed by Russia. The missile is considered one of the world’s most powerful nuclear-capable missiles and is designed to strike targets across long distances in the United States and Europe. Sarmat is the first post-Soviet Russian ICBM classified as “super heavy.” The missile reportedly has a range exceeding 35,000 km and carries a warhead yield significantly greater than Western counterparts.
