Military affairs, defense policies, armed forces developments, and national security matters
The Indian Navy has commissioned INS Nipun, the second indigenous Nistar-class Diving Support Vessel (DSV), at Naval Dockyard, Mumbai. Built by Hindustan Shipyard Limited, the specialised vessel strengthens India's ability to conduct sustained deep-sea diving, underwater intervention, salvage and submarine-rescue missions. Together with INS Nistar and India's two Deep Submergence Rescue Vehicles, INS Nipun creates a more resilient two-seaboard underwater rescue architecture and supports India's ambition to emerge as a dependable submarine-rescue partner in the Indian Ocean Region.
China test-fired a submarine-launched intercontinental ballistic missile from the South China Sea into the Southern Pacific Ocean on 6 July 2026 — its first-ever SLBM launch into international waters and only its second ballistic missile test in international waters since 1980. The missile, believed to be the JL-2 or JL-3, flew over the Philippines and landed in the South Pacific nuclear-free zone, drawing protests from the US, Japan, Australia and Pacific island nations. This article explains ballistic missile basics, the JL missile family, China's nuclear triad and evolving nuclear strategy, the Treaty of Rarotonga, and the implications for India's nuclear deterrent and the Indo-Pacific.
India and Indonesia have reached a major defence-cooperation milestone with Indonesia becoming the first foreign buyer of India’s indigenous Astra Mk-I BVRAAM. The deal, announced during Prime Minister Narendra Modi’s Indonesia visit, is important for UPSC because it connects Atmanirbhar Bharat in defence, air-combat technology, India’s defence exports, India-Indonesia ties and the Indo-Pacific security environment.
A newspaper analysis has argued that artificial intelligence, autonomy and algorithmic warfare are rapidly reshaping modern battlefields, with examples from Ukraine, West Asia and emerging US autonomous aircraft programmes showing how software, drones, sensors and real-time data are compressing the military decision cycle. The issue is important for UPSC because it links AI warfare, national security, drone swarms, defence indigenisation, cyber warfare, space-based surveillance, start-up-led innovation and the ethics of autonomous weapons.
The Armed Forces are reportedly seeking a higher retention percentage for Agniveers after completion of their four-year tenure, with the Navy likely to seek around 75% retention and the Army and Air Force around 50%, against the current approved ceiling of 25%. The issue is important for UPSC because it connects military manpower planning, national security, defence reforms, youth employment, training costs, operational readiness and post-service rehabilitation.
The Indian Navy is set to commission Mahendragiri (F38), its sixth indigenous Project 17A stealth frigate, at Visakhapatnam. Designed by the Navy’s Warship Design Bureau and built by Mazagon Dock Shipbuilders Ltd, the warship highlights India’s shift from a “buyer’s navy” to a “builder’s navy” and strengthens India’s maritime capability in the Indo-Pacific.
On 21 June 2026, the Indian Navy commissioned three indigenously built warships at Kolkata in a single ceremony — the stealth frigate INS Dunagiri, the survey vessel INS Sanshodhak, and the anti-submarine craft INS Agray, all built by GRSE. This article explains the three distinct strategic roles of these ships, decodes Project 17A stealth frigates, hydrographic survey vessels and Anti-Submarine Warfare Shallow Water Craft, and situates the event within India's Atmanirbhar Bharat defence drive and its maritime strategy in the Indian Ocean Region.
An Indian Air Force AN-32 transport aircraft crashed while landing at Jorhat in Assam, killing five IAF personnel, while one co-pilot survived and is under treatment. The incident has brought attention to the AN-32 fleet’s role in military logistics, its modernisation history, safety record and India’s larger need for reliable tactical airlift capability.
On June 10 and 11, 2026, India's Defence Research and Development Organisation (DRDO) carried out three consecutive flight-tests off the Odisha coast that validated a multi-layered Ballistic Missile Defence (BMD) system and successfully conducted the maiden test of the Naval Anti-Ship Missile-Medium Range (NASM-MR). The Ministry of Defence said the interceptors engaged their targets up to the Intercontinental Ballistic Missile (ICBM) class, placing India among a small group of nations with such capability. This article explains India's BMD programme, the difference between the AD-1 and AD-2 interceptors, the science of endo- and exo-atmospheric interception, the significance of NASM-MR, and why this matters for India's strategic deterrence.
The Zojila Tunnel, beneath the avalanche-prone Zojila Pass on National Highway-1, achieved its final excavation breakthrough on 9 June 2026 when engineers blasted through the last stretch of rock to link the Kashmir and Ladakh ends. Once operational, this high-altitude tunnel will provide India's first year-round road link between the Kashmir Valley and Ladakh, ending the region's winter isolation. This article explains the project's features, the strategic and defence significance of the route, India's broader Himalayan border-connectivity push, and the engineering and economic dimensions of this landmark.
The Stockholm International Peace Research Institute (SIPRI) has released its Yearbook 2026, estimating that India's nuclear stockpile has grown to about 190 warheads as of January 2026 (up from 180 a year earlier), moving slightly ahead of Pakistan's estimated 170. SIPRI also assessed that India may have begun deploying a small number of warheads on a nuclear-armed submarine conducting deterrence patrols, hinting at a shift in its long-standing peacetime posture. This article explains the report's key findings, India's nuclear doctrine of credible minimum deterrence and No First Use, the structure of India's nuclear triad and second-strike capability, its command-and-control system, and India's position on global non-proliferation treaties.
