The Indian Navy must reform its submarine acquisition strategy to address a critical deficit in its fleet. Currently, the Navy operates only 16 conventional Submarine (SSK) vessels, while projections indicated a requirement of 24 by 2025. The ageing Sindhugosh and Shishumar classes pose a significant threat to India’s underwater deterrence capability.
On 19 December 2025, the Indian Navy will decommission the INS Sindhughosh, a submarine that has served for four decades, leaving the fleet with 16 conventional SSKs. This number mirrors that of the late 1990s, when an ambitious submarine construction programme was approved but has yet to meet its objectives. The situation is exacerbated by delays in acquisitions and the lack of modern technologies in existing submarines.
Context and Background
In 1999, India’s Cabinet Committee on Security approved a 30-year programme to develop 24 submarines. This plan, proposed by Vice Admiral A.K. Chatterji, envisaged the parallel construction of submarines using initial foreign designs, eventually evolving towards indigenous models. However, to date, only six submarines have been commissioned, and the ageing Sindhugosh and Shishumar classes increase the risk of a capability gap.
Delays in the implementation of Project 75 (P-75I), which aims to introduce Air-Independent Propulsion (AIP) submarines, present an additional challenge. The first SSKs equipped with AIP are expected to be commissioned between 2034 and 2035, coinciding with the time when the older platforms will need to be retired.
In-Depth Technical Analysis
Air-Independent Propulsion (AIP): Viability and Challenges
AIP allows submarines to operate without the need to surface for battery recharging, significantly increasing their underwater autonomy. However, the integration of AIP into the Indian fleet faces technical challenges, such as the need for substantial modifications to current propulsion systems and the limited availability of advanced AIP technology.
Economic and Operational Implications
The cost of modernising existing submarines versus the construction of new platforms is a crucial dilemma. Modernisation can extend the service life of submarines but does not resolve technological obsolescence. Conversely, building new submarines entails a high initial investment but offers advanced capabilities that are critical for deterrence.
Implications for Industry Professionals
The need to modernise and build new submarine platforms creates job opportunities in naval engineering and advanced propulsion technology. Professionals skilled in control systems design and AIP technology will be particularly in demand.
Impact on the Job Market
The increase in submarine construction and modernisation projects in India will drive demand for naval engineers, propulsion system technicians, and AIP technology specialists. Employment and training opportunities in these fields are expected to grow significantly.
Geopolitical and Macro-Environmental Considerations
The submarine deficit in India has significant geopolitical implications, particularly in the context of rivalry with Pakistan, which has enhanced its submarine capabilities through modern acquisitions from China. This affects the strategic balance in the Indian Ocean and jeopardises the security of maritime trade routes.
Outlook
In the short term, India must expedite efforts to complete Project 75I and consider international cooperation to bridge technological gaps. In the long run, self-sufficiency in submarine design and construction will be crucial for maintaining an effective and modern fleet.
