What Happened

  • The Indian Navy deployed an INS Vikrant-led carrier battle group comprising 36 warships into the northern Arabian Sea during Operation Sindoor, launched after the Pahalgam attack in May 2025
  • The fleet included 7 destroyers equipped with BrahMos supersonic cruise missiles, Medium-Range Surface-to-Air Missiles (MRSAM), and Varunastra heavyweight torpedoes, along with 6 submarines operating in close coordination
  • The carrier battle group established a de facto naval blockade, confining the Pakistan Navy to its harbours and the Makran coast in Balochistan
  • Navy Chief Admiral Tripathi stated that Indian forces were "minutes from a sea strike on Pakistan," with Karachi port within the fleet's target range
  • The operation demonstrated India's blue-water naval capability and its ability to project power and establish sea control across the Arabian Sea

INS Vikrant — India's First Indigenous Aircraft Carrier (IAC-1)

INS Vikrant is India's first indigenously designed and built aircraft carrier, commissioned on 2 September 2022 at Cochin Shipyard. It displaces approximately 45,000 tonnes and is 262 metres long, making it the largest warship ever built in India. The carrier uses a STOBAR (Short Take-Off But Arrested Recovery) configuration and is powered by four gas turbines generating 88 megawatts of power.

  • Can carry up to 36 aircraft, including 26 fixed-wing combat aircraft (MiG-29K) and helicopters (Dhruv MK-III, MH-60R Seahawk, Ka-31)
  • Keel laid on 28 February 2009; launched on 12 August 2013; commissioned on 2 September 2022
  • 76% indigenously built, including 30,000 tonnes of specialty steel from SAIL
  • India is one of only six nations capable of designing and building an aircraft carrier (alongside the US, UK, France, Russia, and China)

Connection to this news: INS Vikrant served as the centrepiece of the 36-ship carrier battle group deployed during Operation Sindoor, demonstrating that India's indigenous carrier is fully combat-ready and capable of power projection in a live conflict scenario.

Carrier Battle Group (CBG) — India's Blue-Water Naval Doctrine

A Carrier Battle Group is a naval formation centred on an aircraft carrier, supported by destroyers, frigates, corvettes, submarines, and fleet support ships. India currently operates two CBGs — one centred on INS Vikrant and another on INS Vikramaditya (acquired from Russia in 2013). The CBG concept is central to India's blue-water navy doctrine, which aims to project power across the Indian Ocean Region (IOR).

  • INS Vikrant's CBG typically includes Visakhapatnam-class destroyers, Talwar-class/Nilgiri-class frigates, Kamorta-class corvettes, and fleet tankers
  • India's Maritime Security Strategy (2015) identifies the primary area of interest from the Persian Gulf to the Strait of Malacca
  • The Indian Navy aims for a three-carrier fleet (INS Vikrant, INS Vikramaditya, and the planned IAC-2 Vishal) for sustained two-ocean deployment
  • India is the net security provider in the Indian Ocean Region, as articulated in the SAGAR (Security and Growth for All in the Region) doctrine announced in 2015

Connection to this news: The deployment of a 36-ship carrier battle group that effectively blockaded Pakistan's naval capabilities demonstrates India's ability to establish sea control and deny adversary access — a core tenet of blue-water naval operations.

BrahMos Supersonic Cruise Missile

BrahMos is a supersonic cruise missile jointly developed by India's Defence Research and Development Organisation (DRDO) and Russia's NPO Mashinostroyeniya through the BrahMos Aerospace joint venture (India holds 50.5%, Russia 49.5%). It is one of the fastest cruise missiles in the world, capable of being launched from ships, submarines, aircraft, and land-based mobile launchers.

  • Speed: Mach 2.0–2.8 (supersonic); range: 290 km initially, extended to 450+ km after India joined MTCR in 2016
  • Warhead: 200–300 kg depending on variant (air-launched vs ship/ground-launched)
  • Deployed on Visakhapatnam-class and Kolkata-class destroyers, Talwar-class frigates, and Su-30MKI aircraft
  • BrahMos-II (hypersonic variant under development) targets Mach 8 speed and 1,500 km range
  • India has exported BrahMos to the Philippines (2022, $375 million deal) — its first major missile export

Connection to this news: The 7 destroyers deployed during Operation Sindoor were equipped with BrahMos missiles, placing Karachi and Pakistan's coastal infrastructure within strike range and providing a credible conventional deterrent.

Maritime Blockade and Sea Denial in International Law

A naval blockade is the use of naval forces to prevent maritime commerce from entering or leaving an enemy's ports. Under international humanitarian law, a blockade must meet the criteria of effectiveness, impartiality toward neutral shipping, and proportionality. The San Remo Manual on International Law Applicable to Armed Conflicts at Sea (1994) provides the modern legal framework for naval blockades.

  • A blockade must be declared and notified to all states (San Remo Manual, Rule 93)
  • Neutral vessels may be captured if they attempt to breach a blockade (Rule 98)
  • India's de facto blockade during Operation Sindoor confined Pakistan's navy without a formal declaration
  • The UN Convention on the Law of the Sea (UNCLOS, 1982) governs freedom of navigation; India ratified UNCLOS in 1995
  • Historical precedent: India's naval blockade of East Pakistan during the 1971 war was a decisive factor in the liberation of Bangladesh

Connection to this news: The Indian Navy's forward deployment near Karachi created a de facto blockade scenario, confining Pakistan's fleet to its ports — an operational achievement that demonstrated sea denial capability without requiring a formal blockade declaration.
