The "Carriers vs. Submarines" debate is a classic, but for the Indian Navy, it's not about fighting the wrong war; it's about a strategic dilemma caused by limited resources and an overstretched force.

Both platforms have distinct roles, but India's ambitious goal of becoming a "blue-water navy" with global reach has prioritized carriers, potentially at the expense of its more immediate need for a robust submarine fleet.

The Case for Aircraft Carriers-

Aircraft carriers are the centerpiece of a sea control doctrine. They are mobile, floating airbases that allow a navy to project power over vast distances, secure sea lines of communication (SLOCs), and conduct offensive air operations.

• Power Projection: A carrier battle group can deploy to a crisis zone far from India's coast, projecting a formidable presence and influencing events on land and sea. This is essential for a nation with growing global interests.

• Air Superiority at Sea: Carriers provide organic air power, ensuring air superiority over a theater of operations, protecting the fleet, and enabling land-attack missions.

• Show of Force: The sheer visibility of an aircraft carrier makes it a potent diplomatic tool, showing a nation's resolve and strength without firing a single shot.

India's decision to build the INS Vikrant, its first indigenous aircraft carrier, and to push for a third carrier reflects this blue-water ambition. For a navy that wants to be the dominant force in the vast Indian Ocean Region, a carrier is seen as a necessary tool.

The Case for Submarines-

Submarines, on the other hand, are the key to a sea denial strategy. They are stealthy, lethal, and difficult to counter, making them ideal for a more defensive, asymmetric approach.

• Stealth and Deterrence: A submarine's strength lies in its invisibility. A modern submarine can quietly patrol enemy waters, threaten high-value targets, and deny an adversary freedom of movement. This makes them a powerful deterrent against a superior force.

• Cost-Effectiveness: Submarines are significantly cheaper to build, operate, and maintain than an aircraft carrier and its accompanying battle group. For a resource-constrained navy, this is a major factor.

• Anti-Submarine Warfare (ASW): A robust submarine fleet is crucial for ASW, as it is the most effective way to hunt and destroy enemy submarines, a growing threat in the Indian Ocean.

India's submarine fleet, particularly its conventional diesel-electric submarines, is aging and facing a critical shortage. The Project 75I program to acquire new submarines has been plagued by delays, leaving a glaring gap in the navy's underwater capabilities. While India is also building nuclear-powered submarines, these are primarily for nuclear deterrence and do not solve the conventional force-level problem.

The Dilemma: Two Different Wars-

The Indian Navy isn't fighting the wrong war, but it is grappling with a two-fold problem:

1. Strategic Disconnect: The navy's carrier-centric strategy is aimed at a future war of power projection, while its more immediate and pressing need is to address the present threat of sea denial from a rapidly expanding Chinese navy. China's growing fleet, which includes carriers and a large number of submarines, poses a significant challenge to India's dominance in the IOR.

2. Resource Misallocation: Critics argue that by prioritizing a third aircraft carrier, the navy is diverting funds and resources from the more urgent need to replace its aging submarine fleet. A strong submarine fleet is a more effective and affordable way to counter China's growing presence in the IOR.

The ideal solution for the Indian Navy is not to choose between carriers and submarines but to build both. However, given India's budgetary constraints and slow procurement process, a choice has to be made. While the carriers provide strategic prestige and a visible deterrent, the submarines are arguably the more critical and immediate need for securing India's maritime interests in the face of a rising rival.
