The Indian Navy is intensifying efforts to bolster its sea-based nuclear deterrent capabilities, emphasizing the advancement of its ballistic missile submarine (SSBN) programs alongside conventional submarine initiatives. This strategic shift underscores India’s commitment to maintaining a robust nuclear triad and enhancing maritime defense capabilities.

Advancing the S5 SSBN Program: Strengthening India’s Nuclear Deterrent

With operational Arihant-class submarines and nearing completion of stretched S4 and S4* submarines, the focus now turns to the development of larger S5-class submarines. These submarines, with a targeted displacement of 13,000 tons, represent a significant leap in India’s SSBN capabilities. The Indian Navy prioritizes the S5 program to fortify its nuclear deterrent force, aiming for the introduction of the first submarine by 2031-32.

Strategic Investments in P75I and P76 Submarine Programs

In alignment with its maritime defense strategy, the Indian Navy is channeling resources towards the Project-75I (P75I) and Project-76 (P76) submarine programs. The procurement of next-generation conventional submarines, followed by locally designed variants, takes precedence over indigenous nuclear-powered attack submarines. This strategic decision underscores India’s focus on modernizing its submarine fleet and enhancing operational readiness.

P75I and P76 Progress: Procurement and Design Advancements

Despite delays in the P75I program, the Indian Navy remains committed to securing essential components from foreign suppliers to expedite submarine construction under the P76 program. The P76 initiative involves acquiring 12 diesel-electric submarines equipped with Air Independent Propulsion (AIP) technology, with the preliminary design phase slated for completion by 2025.

Timeline for Indigenous Nuclear-Powered Attack Submarines

While plans for indigenous nuclear-powered attack submarines remain on the horizon, timelines may be extended to around 2035. Initial design work is projected to conclude by 2026-27, with construction estimated to take 7-8 years. This delay underscores the complexity of developing indigenous nuclear submarines and emphasizes the Indian Navy’s commitment to ensuring technological proficiency and operational excellence.
