1. INS Arighat has a submerged displacement of around 6,000 tons.
The submarine is approximately 111 meters (364 feet) long and 11 meters (36 feet) wide.
2. Propulsion: It is powered by a nuclear reactor which provides it with virtually unlimited range and endurance, allowing it to remain submerged for extended periods.
3. Armament: INS Arighat is equipped with ballistic missiles capable of carrying nuclear warheads. The specific missiles include the K-15 Sagarika and potentially the K-4 missile, both designed to enhance the submarine’s strategic strike capabilities.
4. The submarine features advanced stealth technology to reduce its detectability by enemy sonar systems. Its design incorporates lessons learned from INS Arihant, improving its operational effectiveness and survivability.
