India has historically operated as a continental military power due to immediate border frictions, yet its geography and future prosperity are fundamentally tied to maritime supremacy. The nation possesses a vast peninsular coastline extending across more than 7,516 kilometres, complemented by an Exclusive Economic Zone covering over 2 million square kilometres. Situated centrally along the world's most critical sea lanes of communication and global trade networks, the Indian subcontinent occupies an indispensable geographic position. Despite this reality, the degree of institutional and budgetary priority granted to maritime defence remains a pressing strategic concern.
Continental Friction and the Legacy of Border Preoccupations
India's operational security planning has traditionally been anchored along its northern and western frontiers. Flanked by two aggressive, nuclear-armed adversaries, national defence structures have understandably maintained an unyielding vigil on land. Continuous friction and operational volatility along the Line of Control with Pakistan necessitate permanent troop deployments and intense resource commitment.
Concurrently, repeated incursions and standoffs along the Line of Actual Control by the People's Liberation Army of China have reinforced the armed forces' continental orientation. Bitter memories of the 1962 conflict, combined with the wars of 1965, 1971, and the 1999 Kargil conflict, have deeply entrenched a land-centric doctrine within the defence establishment. Consequently, operational priorities have consistently been dictated by immediate threats across mountainous terrain.
Guarding Mountain Peaks While Leaving the Ocean Open to Strategic Risks
A comprehensive defence doctrine requires balanced vigilance across every front rather than excessive reliance on territorial fortifications alone. Securing mountain passes while neglecting oceanic perimeters mirrors the vulnerability of a fortress built with an unguarded back gate. Historical precedents demonstrate that regional influence hinges on sea control; the ancient Chola Empire briefly recognized that command over maritime corridors directly supported political power onshore. Later rulers, however, abandoned this doctrine and restricted their geopolitical vision strictly to territorial boundaries.
When European mercantile powers arrived across the Indian Ocean during the fifteenth and sixteenth centuries, their conquest was not executed via overland incursions from the north. Instead, they methodically asserted control over key trade arteries, established fortified coastal outposts, and progressively converted commercial footholds into a vast colonial dominion. Failing to dominate the sea ultimately cost the subcontinent its territorial independence.
The Critical Vulnerabilities Exposed by the 26/11 Maritime Incursion
The modern peril of insufficient coastal domain awareness was tragically illustrated during the 26/11 terrorist attacks in Mumbai. Ten heavily armed operatives exploited open maritime approaches, embarking on a vessel from Karachi and sailing undetected straight into the financial heart of the nation.
The tragedy laid bare profound gaps in surveillance architectures and multi-agency coordination. A resource-constrained Coast Guard and fragmented coastal surveillance networks failed to intercept a small inflatable craft carrying a handful of attackers. If non-state actors could exploit such operational blind spots to execute mass devastation, the strategic repercussions of confronting a well-equipped, hostile blue-water adversary at sea would be vastly more severe.
Naval Modernization and Beijing's Expanding Footprint in the Indian Ocean
A major geopolitical challenger is actively accelerating its presence across the Indian Ocean region. Recognizing early on that blue-water supremacy is the defining attribute of a global superpower, Beijing has constructed the world's largest naval fleet by ship count. The People's Liberation Army Navy has transitioned from a modest coastal defense force into an expeditionary maritime entity capable of projecting decisive power far beyond its territorial waters.
China's maritime strategy has steadily materialized through concrete overseas infrastructure. Establishing its first foreign military base in Djibouti, alongside acquiring operational leverage over commercial ports in Gwadar and Hambantota through debt diplomacy, reflects a cohesive encirclement initiative frequently termed the String of Pearls. This continuous naval expansion directly challenges regional sovereignty, pressures smaller littoral states, and threatens to restrict strategic maneuverability across vital transit corridors.
Securing Commercial Lifelines and Preserving the Regional Security Role
Securing open commercial transit is an existential imperative, given that more than 90 percent of national foreign trade moves across maritime highways. Any disruption along these choke points would instantly imperil energy supplies and economic stability. Furthermore, sustaining the traditional role of a net security provider across South Asia relies entirely on robust naval projection.
Littoral neighbours including Sri Lanka and the Maldives instinctively look to New Delhi during instances of maritime threats, search-and-rescue operations, and major natural calamities. Should operational capabilities diminish, an immediate strategic vacuum would emerge, which rival powers are already positioned to occupy. Beyond humanitarian roles, an expansive naval fleet is vital to enforce deterrence along the western coast near Pakistan and ensure stability across the Bay of Bengal.
Persistent Disparities in Defence Budgetary Allocation
Despite these critical responsibilities, recent Union budgets continue to reflect a profound structural imbalance among the three armed services. Driven by enormous manpower and establishment overheads, the land army has historically consumed the overwhelming bulk of defence outlays, typically receiving between 55 to 60 percent of total expenditure.
The Indian Air Force generally garners around 19 percent, leaving the naval service with the smallest allocation among the three branches. Given the capital-intensive nature of building modern surface combatants, procuring advanced submarines, and maintaining wide-area maritime surveillance networks, persistent fiscal constraints risk stifling long-term fleet modernization. Addressing this imbalance is increasingly seen as essential to securing sovereign economic and maritime interests.
