As India emerges as a leading geopolitical and economic power, the importance of military strength extends far beyond defending borders. In an increasingly contested Indo-Pacific and amid a persistent two-front challenge from China and Pakistan, India’s ability to project power through the air and across the seas has become central to its national security strategy.
The Indian Navy and the Indian Air Force (IAF) are among the country’s most technologically advanced military services. Both have demonstrated impressive operational capabilities, but both also face critical shortages and modernization challenges that could shape India’s strategic future.
A Blue-Water Force With Growing Reach
Over the last two decades, the Indian Navy has transformed itself from a coastal defence force into a credible blue-water navy capable of operating across the Indian Ocean Region (IOR). Geography remains its biggest advantage. Situated at the heart of the Indian Ocean, India enjoys proximity to some of the world’s busiest sea lanes through which much of global trade and energy supplies pass.
The Navy today operates two aircraft carriers, INS Vikrant and INS Vikramaditya, supported by a modern fleet of destroyers, frigates and corvettes equipped with long-range BrahMos missiles. It has also made significant progress in indigenous shipbuilding, with most frontline warships now being built in Indian shipyards.
Another major achievement is the development of a sea-based nuclear deterrent through the Arihant-class ballistic missile submarines, completing India’s nuclear triad and strengthening its second-strike capability.
The Concerns
However, beneath these successes lie serious concerns. The Navy’s most significant weakness is its shortage of submarines. While India’s maritime ambitions have grown, its underwater fleet has struggled to keep pace. Several conventional submarines are ageing, and long delays in induction of new platforms have created capability gaps.
Equally worrying is the absence of an operational fleet of indigenous nuclear attack submarines (SSNs), considered essential for escorting carrier groups, tracking enemy submarines and projecting power over long distances.
The Navy also faces shortages in naval aviation assets, including carrier-based fighters, anti-submarine helicopters and surveillance aircraft. Delays in projects such as Project 75(I) submarines, mine countermeasure vessels and amphibious ships have further slowed force expansion.
The Galathea Bay Deterrent
The proposed deep-sea transshipment port at Great Nicobar could partially address some of these challenges. Strategically located near the Malacca Strait, one of the world’s most critical maritime chokepoints, the project could evolve into a major logistics and operational hub for the Navy. It would enhance surveillance of Chinese naval movements, support submarine deployments and strengthen India’s ability to maintain a sustained presence in the eastern Indian Ocean.
In the long term, however, the Navy’s greatest requirement remains clear: more submarines. Conventional submarines, nuclear attack submarines and advanced anti-submarine warfare capabilities will likely determine India’s maritime balance with China over the coming decades.
High Capability, Low Numbers
If the Navy’s challenge is underwater strength, the IAF’s challenge is numerical strength. The Indian Air Force remains one of the world’s most professional and combat-experienced air forces. From the 1971 war to Kargil and Balakot, it has repeatedly demonstrated operational excellence. Its frontline fleet includes Rafale, Su-30MKI, Mirage 2000, MiG-29UPG and the indigenous Tejas fighter.
The IAF also possesses critical force multipliers such as AWACS aircraft, strategic airlifters, attack helicopters and one of the world’s most sophisticated air defence networks, anchored by the S-400 missile system. These capabilities give India the ability to rapidly concentrate air power across theatres and conduct precision strikes deep inside enemy territory.
MiG Gone, Tejas Delayed
Yet, despite these strengths, the IAF faces what many defence experts consider its most serious crisis in decades: a shortage of fighter squadrons. Against an authorised strength of 42 fighter squadrons, the IAF currently operates only around 30 to 32. The retirement of ageing MiG-series aircraft has outpaced the induction of replacements, creating a gap that could prove critical during a prolonged two-front conflict.
The challenge is compounded by limited numbers of airborne warning aircraft and aerial refuelling tankers, both of which are essential for sustaining modern air operations over long distances. Dependence on imported platforms and relatively slow production of indigenous aircraft further add to the problem.
China’s rapid military modernisation has sharpened these concerns. The People’s Liberation Army Air Force now fields large numbers of advanced fighters, extensive AWACS and tanker fleets, and fifth-generation stealth aircraft. Simultaneously, growing military cooperation between China and Pakistan presents an increasingly complex strategic challenge for India.
The IAF’s immediate priority, therefore, is straightforward: restore squadron strength. Faster production and induction of Tejas Mk1A fighters, accelerated development of Tejas Mk2 and eventual deployment of the Advanced Medium Combat Aircraft (AMCA) will be crucial to achieving this objective.
The Road Ahead
Both services possess highly trained personnel, advanced platforms and growing indigenous capabilities. Both have demonstrated professionalism and operational effectiveness under challenging conditions. Yet both also face critical shortages that cannot be ignored.
For the Navy, the future lies beneath the waves, requiring rapid expansion of submarine capabilities and stronger maritime infrastructure in the Andaman and Nicobar Islands. For the Air Force, the challenge lies in restoring combat mass through faster aircraft induction and enhanced force multipliers.
As India seeks to secure its interests from the Himalayas to the Indo-Pacific, the effectiveness of its air and maritime power will increasingly define its strategic influence. The platforms may differ, but the message from both services is remarkably similar – capability matters, but numbers matter too.
