The Indian Ocean Region is witnessing an unprecedented military and economic transformation. Chinese warships are becoming more frequent visitors, maritime chokepoints are under pressure, and conflicts in West Asia continue to threaten global shipping. India’s current two-carrier structure leaves little room for operational flexibility, especially when one vessel undergoes maintenance. Strategic analysts say the next decade could define whether India remains the primary security provider in the region or cedes space to extra-regional powers.
Senior Indian Navy officials have consistently flagged the country’s two-carrier force structure as operationally insufficient for sustaining simultaneous carrier battle groups in both the Arabian Sea and the Bay of Bengal, with internal assessments pointing to an urgent need for a third indigenous aircraft carrier before the mid-2030s. The concern is not hypothetical. INS Vikramaditya, the Navy’s 45,000-tonne ex-Russian carrier that has been in service since 2013, faces a critical structural audit in 2035 that will determine whether the vessel can continue to serve for its full projected lifecycle — potentially to 2052 — or whether it will need to be decommissioned closer to 2037. Defence planners, analysts say, cannot responsibly anchor a two-ocean deterrent posture around the more optimistic of those two outcomes.
INS Vikrant, the domestically built carrier commissioned in 2022 and constructed at Cochin Shipyard for Rs 20,000 crore, is the more assured element of India’s carrier future. But one carrier does not satisfy what naval doctrine describes as the “rule of three”: the operational principle that maintaining one carrier continuously available in each of two theatres requires three hulls in total, since one is always undergoing scheduled maintenance or systems overhaul at any given time.
The strategic context has sharpened considerably over the past two years. China’s People’s Liberation Army Navy now operates three aircraft carriers — Liaoning, Shandong, and the recently commissioned Fujian — with a stated ambition of expanding to as many as nine by 2035. Beijing has also extended its maritime footprint into the Indian Ocean Region through port access agreements with Djibouti, Sri Lanka, Pakistan, and Bangladesh, a strategy analysts describe as the “String of Pearls”.
Meanwhile, the Red Sea crisis of 2023–24 demonstrated the leverage that carrier battle groups provide in protecting sea lanes. The United States deployed multiple carrier strike groups to the region, providing air cover for commercial shipping threatened by Houthi attacks and conducting offensive strikes against Houthi launch infrastructure in Yemen. India, which imports over 83 per cent of its crude oil through routes that pass near the affected waters, had no equivalent capability to deploy.
“What the Red Sea showed was that carrier battle groups are the decisive instrument when you need to impose military consequences over a large maritime area for an extended period,” said a Mumbai-based naval analyst. “Destroyers and submarines have their roles, but the carrier is what creates the sustained air environment that everything else operates under.”
The domestic industrial dimension adds urgency to the timeline question. Cochin Shipyard’s construction of Vikrant placed India among six nations worldwide with indigenous carrier-building capability. Defence economists and shipbuilding experts warn that this capability requires a follow-on contract to remain viable — that the engineering expertise, supplier networks, and institutional knowledge developed during Vikrant’s construction will erode if no third carrier order is placed within the next several years.
A third carrier ordered now would not enter service until the mid-2030s at the earliest, given the timelines involved in design finalisation, procurement, and construction. That makes the urgency of the decision more acute, not less. The window in which a third carrier could be available before Vikramaditya’s structural audit — and before China’s carrier programme reaches its next milestone — is narrowing.
India’s SAGAR doctrine commits the country to being a net security provider in the Indian Ocean Region, a posture backed by the QUAD partnership with the United States, Japan, and Australia. Naval analysts argue that this commitment requires the platform capability to make it credible across both of India’s maritime flanks simultaneously.
