The deployment of three American supercarriers into West Asian waters during the ongoing regional crisis has once again underlined a hard strategic truth: nations that can project sustained air power at sea retain the ability to shape economic and military outcomes far beyond their shores. The USS Gerald R. Ford, USS Abraham Lincoln, and USS George H.W. Bush were not deployed merely as symbols of deterrence.
Together, they created an operational shield across critical maritime corridors stretching from the eastern Mediterranean to the Strait of Hormuz.
The result was immediate. Dozens of tankers linked to Iranian crude trade were reportedly diverted or disrupted, tightening economic pressure on Tehran and affecting oil flows worth billions of dollars. The episode demonstrated how carrier strike groups can influence global trade routes, energy markets, and strategic calculations without a single ground invasion.
Two years ago, Operation Prosperity Guardian was launched in December 2023 as an international coalition effort to protect Red Sea shipping from Houthi attacks. At the core of the operation were American aircraft carriers.
Multiple carrier strike groups — the USS Dwight D. Eisenhower, the USS Theodore Roosevelt, and the USS Abraham Lincoln — rotated through the Red Sea and Gulf of Aden across months of sustained operations. Their air wings intercepted Houthi drones and ballistic missiles. Strike packages hit Houthi missile storage, radar installations, and launch sites in Yemen.
India participated in the broader counter-threat environment through its own naval deployments — escort missions, surveillance, and presence operations. The Indian Navy performed creditably in its assigned role. But the Indian Navy’s role was supporting, not decisive. And the reason for that is not doctrinal. It is structural.
India did not have a carrier battle group available to deploy with sufficient mass for sustained offensive-defensive operations in that region.
For India, the lesson is impossible to miss. Nearly 80–85 percent of the country’s crude oil imports move through vulnerable sea lanes connected to the Gulf and the Arabian Sea. In a future crisis, protecting these routes may require more than diplomacy or coastal defence. It may require the ability to maintain continuous carrier-led operations across the Indian Ocean Region.
As China rapidly expands its naval footprint and maritime competition intensifies, many within India’s strategic community believe the case for a third aircraft carrier is no longer about prestige — it is about ensuring that India retains the capability to secure its economic lifelines and impose pressure, if necessary, at a time and place of its choosing.
Why does this matter? Because what was at stake in the Red Sea was not just the principle of freedom of navigation. It was the physical security of trade routes through which India’s economy breathes. India imports over 83 per cent of its crude oil.
A significant portion of that oil, along with a substantial share of its containerised imports, transits the Red Sea. When those routes were under threat, and when the military instrument that protected them was American, India was — to put it plainly — dependent on a foreign power to secure its own supply chains.
That dependency is tolerable as a temporary condition and unsustainable as a permanent one.
The aircraft carrier is the instrument that changes this. A carrier battle group — the carrier plus its escorts of destroyers, frigates, and submarines, plus its organic air wing — can conduct sustained offensive and defensive air operations over open ocean, far from friendly shore bases, for weeks.
It can intercept airborne threats, strike land-based targets, impose a maritime blockade, or conduct humanitarian operations. It can do all of these simultaneously if required, and it can keep doing them while the adversary decides whether the cost of continued aggression is worth paying.
No collection of surface combatants without a carrier can do this. No shore-based air force has the reach, the endurance, or the continuous presence over open ocean that a carrier provides. The carrier is a unique instrument — and its operational utility was demonstrated in the Red Sea with a clarity that a decade of strategic seminar papers could not have matched.
The lesson for India is specific. The Indian Ocean is India’s strategic domain in a way that the Red Sea is not an American one.
India’s trade, India’s oil, India’s island territories, India’s regional partnerships — all of them are concentrated in waters that India has claimed, through the SAGAR framework and through decades of naval doctrine, as its primary area of responsibility. Being a net security provider in those waters requires the ability to independently conduct the kind of persistent, multi-domain maritime operations that Operation Prosperity Guardian demonstrated.
India currently fields two carriers — INS Vikramaditya and INS Vikrant. The naval planning standard for maintaining two continuous carrier battle group deployments, one in the Arabian Sea and one in the Bay of Bengal, requires three hulls because one is always unavailable for maintenance. India’s two-carrier fleet means this standard is met only part of the time. When one carrier is in the yard, India’s two-seaboard requirement is simply not achievable.
China’s PLAN has three carriers in service and is building more, with a stated goal of nine by 2035. Its port access across the Indian Ocean provides the logistics support for a navy that is clearly planning to operate as a permanent presence in India’s strategic neighbourhood. Against that trajectory, India’s two-carrier fleet — with one carrier’s post-2037 service life uncertain pending a 2035 structural audit — does not constitute a credible deterrent posture.
The Hormuz blockade by the USA and Operation Prosperity Guardian showed what carrier-enabled maritime operations look like. They protected, among other things, India’s supply routes. The next time a similar threat emerges in India’s maritime neighbourhood, the question is whether India will be the net security provider its doctrine promises, or whether it will be a participant in someone else’s coalition
