According to a source familiar with the Nuclear Attack Submarine (SSN) program, the design for India’s new attack submarine, currently in the design phase, is expected to be ready by early or mid-2029. This next-generation SSN will mark a significant departure from the Arihant-class ballistic missile submarines (SSBNs), representing a modern and advanced platform tailored for attack missions.
The Indian Navy initially embarked on the Arihant-class project as an SSN program. However, before construction commenced, the design was modified to create India’s first SSBN fleet. Now, with the Ministry of Defence (MoD) granting clearance for the dedicated SSN program, the first two nuclear attack submarines will be based on an entirely new design that will incorporate state-of-the-art advancements in stealth, manoeuvrability, and combat effectiveness.
Sources indicate that the new SSN design will feature a cylindrical hull profile, reducing hydrodynamic resistance and enabling silent underwater movement—an essential factor for stealth operations. These submarines are also expected to integrate key engineering advancements, ensuring they are on par with the latest nuclear-powered attack submarines in service worldwide.
The Navy is keen on integrating several key engineering advancements. These include improvements in stealth technology, enhanced manoeuvrability, and increased combat effectiveness, all tailored to modern naval warfare requirements.
Mainstream media reports have suggested that the submerged displacement of these submarines will be close to 10,000 tons, placing them in the same league as some of the most advanced SSNs. However, sources familiar with the matter have clarified to idrw.org that the actual submerged displacement will be more than 7,000 tons but will not exceed 10,000 tons, as the program has only recently entered the design phase.
Post-design, the actual development work is anticipated to start in 2030, once the design has been thoroughly reviewed, frozen, and approved by the Indian Navy. This will involve the construction of the first two SSNs under this new program.
