All Submarines of the Indian Navy

We take immense pride in the growth and capabilities of our submarine fleet, reflecting our commitment to defending our waters while ambitiously driving towards self-reliance in defense technologies. This article is dedicated to unveiling the expanse and might of the entire fleet of Indian Navy submarines, exploring the historical evolutions, and shedding light on the sophisticated Shishumar, Kalvari, and Arihant-class submarines.

As we steer through the waves of this discussion, we also anticipate the future trajectories of indigenous submarine development, echoing the aspirations of the Indian Navy’s Maritime Capability Perspective Plan.

Historical Evolution of Indian Submarine Fleet

The genesis of our submarine fleet, a cornerstone of the Indian Navy’s offensive and defensive strategies, can be traced back to the early 1960s. We embraced the strategic significance of submarines and initiated our journey with the acquisition of Foxtrot-class submarines from the Soviet Union. This pivotal move marked our foray into the realm of underwater warfare, laying the groundwork for future advancements.

  • Early Acquisitions and Indigenous Developments:
    • 1960s: Acquisition of Foxtrot-class submarines from the Soviet Union.
    • 1990s: Commissioning of India’s first indigenous submarines, INS Shalki and INS Shankul, marking a significant leap towards self-reliance in submarine technology.

      Our aspirations have always been to modernize and enhance our capabilities. The introduction of Scorpene-class submarines, also known as Kalvari-class, under the collaboration with France’s Naval Group, represents our enduring efforts to bolster our underwater warfare capabilities. The first of these advanced submarines was commissioned in 2017, with a total of six planned for induction by 2023.
  • Modernization and Expansion:
    • 2017: Commissioning of the first Scorpene-class submarine.
    • By 2023: Induction of six Scorpene-class submarines, a testament to our commitment to fortifying our maritime security.

      In our pursuit of a formidable and versatile fleet, we aim to acquire a mix of nuclear-powered attack submarines (SSNs) and nuclear-powered ballistic missile submarines (SSBNs). These acquisitions are pivotal in maintaining a strategic edge in the region. However, the path has not been without its challenges, including budget constraints and initial procurement delays due to reluctance from the USA and Britain.
  • Challenges and Fleet Composition:
    • Financial constraints and procurement challenges have historically impacted fleet expansion.
    • Current Fleet: Operates one nuclear-powered submarine (Chakra), two nuclear-powered ballistic missile submarines (Arihant), and diesel-electric submarines across three classes – Kalvari, Shishumar, and Sindhughosh.

      In our journey, we have bid farewell to 12 submarines, including 2 nuclear-powered and 10 diesel-electric, recognizing their service to our nation. As we continue to safeguard our waters, the submarines of the Indian Navy are not just vessels but embodiments of our naval aspirations and the guardians of our maritime sovereignty.
