INS Aridaman Class: India 3rd Nuclear Submarine SSBN Classification

INS Aridaman, India's 3rd nuclear-powered ballistic missile submarine, belongs to which class of submarines?

Correct Answer: Arihant Class

INS Aridaman is India's 3rd Nuclear-Powered Ballistic Missile Submarine (SSBN), belonging to the Arihant class, developed under the Advanced Technology Vessel (ATV) Project. Commissioned in 2026, it displaces 7,000 tonnes and carries K-15 (700 km range) and K-4 (3,500 km range) Submarine-Launched Ballistic Missiles (SLBMs) through 8 Vertical Launch System (VLS) tubes. With its induction, India becomes only the 6th nation to operate 3 SSBNs simultaneously, thereby completing and firmly solidifying the sea leg of its nuclear triad under the No First Use doctrine.

Arihant Class SSBNs — All Three Submarines

• INS Arihant: 1st SSBN — Commissioned 2016; 6,000 tonnes; 4 VLS tubes; completed first deterrence patrol in 2018
• INS Arighat: 2nd SSBN — Commissioned 2024; similar specs but more technologically advanced
• INS Aridaman: 3rd SSBN — Commissioned 2026; 7,000 tonnes; 8 VLS tubes; more advanced reactor ✔

India's Nuclear Triad

• Land: Agni series ballistic missiles
• Air: Rafale, Su-30MKI aircraft
• Sea: Arihant-class SSBNs (2nd-strike capability under No First Use doctrine)

Why Other Options Are Wrong

• Chakra class — INS Chakra was a nuclear-powered attack submarine (SSN) leased from Russia; a different category from SSBN and not indigenously built.
• Kalvari class — These are conventional diesel-electric attack submarines (SSK) built under Project-75 with French Scorpene design; not nuclear submarines.
• Sindhurakshak class — Sindhurakshak was a Kilo-class conventional Russian-origin submarine of the Indian Navy; not a nuclear vessel or a separate indigenous class.

INS Aridaman, भारत की तीसरी Nuclear-Powered Ballistic Missile Submarine, किस Class की Submarine है?

Correct Answer: Arihant Class

INS Aridaman भारत की तीसरी Nuclear-Powered Ballistic Missile Submarine (SSBN) है, जो Arihant Class से संबंधित है। इसे Advanced Technology Vessel (ATV) Project के तहत विकसित किया गया है। 2026 में Commissioned, यह 7,000 Tonnes Displace करती है और 8 Vertical Launch System (VLS) Tubes के माध्यम से K-15 (700 km Range) और K-4 (3,500 km Range) Submarine-Launched Ballistic Missiles (SLBMs) ले जा सकती है। इसके Induction से भारत अब एक साथ 3 SSBNs Operate करता है, जिससे Nuclear Triad का Sea Leg Solidify होता है।

Arihant Class SSBNs — तीनों Submarines

• INS Arihant: पहली SSBN — Commissioned 2016; 6,000 Tonnes; 4 VLS Tubes; 2018 में पहला Deterrence Patrol Complete
• INS Arighat: दूसरी SSBN — Commissioned 2024; Similar Specs लेकिन अधिक Technologically Advanced
• INS Aridaman: तीसरी SSBN — Commissioned 2026; 7,000 Tonnes; 8 VLS Tubes; अधिक Advanced Reactor ✔

India की Nuclear Triad

• Land: Agni Series Ballistic Missiles
• Air: Rafale, Su-30MKI Aircraft
• Sea: Arihant-Class SSBNs (No First Use Doctrine के तहत 2nd-Strike Capability)

Other Options क्यों गलत हैं

• Chakra Class — INS Chakra एक Nuclear-Powered Attack Submarine (SSN) थी जो Russia से Lease पर ली गई थी; SSBN से अलग Category है और Indigenously Built नहीं थी।
• Kalvari Class — ये Project-75 के तहत French Scorpene Design से बनी Conventional Diesel-Electric Attack Submarines (SSK) हैं; Nuclear नहीं।
• Sindhurakshak Class — Sindhurakshak एक Kilo-Class Conventional Russian-Origin Submarine थी; Nuclear Vessel नहीं।
