Overview
- Officials and recent statements from Navy chief Admiral Dinesh K Tripathi indicate the submarine is in final sea trials with commissioning targeted for this spring.
- Built by Larsen & Toubro at the Ship Building Centre in Visakhapatnam, the 7,000‑tonne vessel uses an 83 MW nuclear reactor designed for long, quiet patrols.
- Aridhaman is expected to field K‑15 submarine‑launched ballistic missiles of about 750 km range and carry a heavier K‑4 loadout reported at more than 3,000 km.
- The induction follows INS Arihant (2016) and INS Arighaat (2024), with a fourth Arihant‑class boat anticipated around 2027 and a larger S5 class in planning.
- Parallel undersea programs continue, including a leased Russian Akula‑class attack submarine projected for 2027–28 delivery and India–Germany talks on six AIP‑equipped conventional submarines under Project‑75(I).
