India’s Submarine Delays: Straining Defense and Regional Stability

India’s ambitious plan to build six new conventional submarines, worth US$6 billion, has been marred by significant delays, revealing serious flaws in the country’s defense strategy and its struggle to build a self-sustaining military industry. What was supposed to be a display of India’s growing defense capabilities has instead become a tale of bureaucratic inefficiency, technical setbacks, and missed opportunities. These delays, now stretching over a year, threaten not only Prime Minister Narendra Modi’s vision of transforming India into a global defense manufacturing hub but also risk weakening the nation’s position in a rapidly changing and volatile South Asia. The consequences of these setbacks are far-reaching, impacting both regional stability and India’s ability to maintain its strategic edge.

The root of the problem lies in the defense acquisition policy championed by Modi’s government, which aims to reduce India’s dependence on foreign suppliers by building a robust domestic defense industry. This policy encourages foreign manufacturers to partner with Indian companies, share technology, and establish military production facilities in India. However, the delays in the submarine project, caused by complaints from local contractors during critical field trials, highlight that India’s indigenous defense capabilities are still struggling to meet the complex demands of modern military technology.

These delays are not just about missed deadlines; they reflect deeper issues within India’s defense ecosystem. Despite being the world’s largest weapons importer, India has not been able to transition smoothly from being a consumer of foreign technology to a producer of sophisticated military hardware. The local defense contractors—such as Mazagon Dock Shipbuilders and Larsen & Toubro (L&T)—lack the advanced technological expertise required to execute such complex projects. Instead of showcasing India’s growing self-reliance, these delays expose the inadequacies of the domestic defense sector and its inability to meet the world-class standards needed for modern warfare.

India’s problems are not limited to this particular project. A look at past naval programs reveals similar setbacks. Take, for example, the INS Arihant, India’s first indigenously built nuclear-powered submarine. Despite the immense pride associated with the project, it was plagued with technical and construction delays. Issues with the reactor and propulsion systems led to years of delays, with the submarine becoming operational only after significant setbacks. The readiness of India’s nuclear submarine fleet was called into question, highlighting the challenges India faces in building advanced naval platforms.

Similarly, the Scorpène submarine project, developed with the French shipbuilder DCN, also encountered numerous problems. Construction delays, cost overruns, and a major security breach in 2016—when confidential design documents were leaked online—have plagued the project. Even now, the Scorpène submarines suffer from technical issues, particularly with their sonar and torpedo systems, which are vital for the submarine’s operational effectiveness. The delays and failures in these past projects have only added to the uncertainty surrounding India’s current submarine program, raising concerns about the country’s ability to maintain a modern, ready naval fleet.

The impact of these technological shortcomings extends far beyond India’s defense industry. The Indian Navy is at a critical crossroads, with many of its older conventional submarines nearing the end of their service life. The delay in acquiring new submarines is exacerbating this problem, leaving a dangerous gap in India’s naval capabilities at a time when tensions in the Indian Ocean and Indo-Pacific regions are intensifying. China, India’s primary strategic rival, has rapidly expanded its naval presence, increasing its number of warships, submarines, and other advanced platforms throughout the region. With each delay in India’s submarine program, China gains an advantage, further shifting the regional balance of power.

China’s growing naval presence in the Indian Ocean is a serious threat to India’s national security. This region, crucial for global trade and energy flows, has become a battleground for influence among major powers, including India, China, the United States, Australia, and Japan. As China’s naval capabilities continue to expand, particularly its investments in submarine technology, the delicate balance of power in the Indian Ocean is being disrupted. India’s delay in modernizing its own submarine fleet weakens its ability to counterbalance China’s growing influence and complicates its role in the Quad, a strategic alliance formed to counter China’s regional ambitions.

India is increasingly at risk of losing its maritime dominance in the Indian Ocean if it fails to modernize its fleet in a timely manner. This threat is compounded by the broader geopolitical landscape. While India has made efforts to strengthen ties with Western powers, such as the United States, Australia, and Japan, delays in military modernization—particularly in naval capabilities—undermine its credibility as a regional security leader. These setbacks send a message that India’s defense strategy is faltering, and its vision of self-reliance may not be achievable in the short term.

The regional instability caused by these delays is not confined to maritime threats alone. India’s failure to upgrade its navy’s capabilities weakens its deterrence against potential Chinese incursions in the Indian Ocean. This creates an opening for other regional players, like Pakistan, to modernize their own naval fleets, fueling an arms race in South Asia. This reactive posture, where each country scrambles to catch up with the others, creates a precarious security environment marked by mistrust and miscalculation.

The political implications of these delays are also significant. Modi’s defense acquisition policy was meant to promote domestic production of military hardware, reduce reliance on foreign suppliers, and position India as an emerging defense exporter. However, the delays in the submarine project highlight the shortcomings of this policy, as both local and foreign contractors struggle with unclear procedures and unresolved disputes. India’s defense industrial complex may need further investment, restructuring, and expertise if it is to meet the demands of 21st-century warfare.

In a time of rising regional threats and global competition for military supremacy, India’s failure to make progress on key defense projects like its submarine program undermines its strategic goals. These delays not only weaken India’s naval capabilities but also raise serious questions about the country’s ability to defend its maritime borders in a rapidly evolving security environment. The continued delays in launching its submarine construction program expose deep weaknesses in India’s indigenous defense capabilities and pose a direct threat to regional stability. India’s failure to modernize its fleet, combined with the difficulties of implementing its self-reliance strategy, undermines its ability to assert itself as a regional power in the face of China’s expanding influence.

India’s defense modernization efforts, particularly in its naval sector, are at a critical juncture. The setbacks in both conventional and nuclear submarine projects reflect broader problems within India’s defense industry. As China strengthens its regional influence and other South Asian countries accelerate their own military advancements, India’s inability to modernize its fleet and achieve its self-reliance goals could erode its standing as a regional power, destabilizing the already fragile security situation in South Asia.
