Modi Likely To Launch India’s Second Nuke Submarine Next Month
Exactly 8 years after India launched its first nuclear submarine INS Arihant, the second underwater nuclear of the same class is said to be ready for grand launch next month by Prime Minister Narendra Modi.
The first submarine was launched by then Prime Minister Manmohan Singh in September 2009. His wife Gursharan Kaur had formally launched the vessel according to the tradition of the Indian Navy as a lady is supposed to to inaugurate the ship.
The second nuclear Submarine IND Aridaman is likely to be launched in the last week of next month at Shipbuilding facility in Visakhapatnam, sources told Defence Aviation Post.
INS Aridaman is likely to be bigger then its previous avatar and more lethal in all parameters, said the sources. The first submarine was inducted into the Navy last year in a hush hush manner. The launch of the second nuclear submarine comes in the ongoing military standoff with China.
INS Aridhaman is the second nuclear-powered ballistic missile submarine being built by India. She is being built under the Advanced Technology Vessel (ATV) project to build nuclear submarines at the Ship Building Centre in Visakhapatnam. Even though the same class as INS Arihant, she will feature 8 launch tubes instead of the 4 giving her double the firepower of Arihant. Thus she could carry 24 K-15 Sagarika short range SLBMs or 8 K-4 long range SLBMs.
The submarine has eight launch tubes in its hump. She can carry up to 24 K-15 Sagarika missiles (each with a range of 750 km or 470 mi), or 8 of the under-development K-4 missiles (with a range of 3,500 km or 2,200 mi).
INS Aridhaman will be fitted with the sonar ISS (Integrated Sonar Suite), state-of-the-art sonar developed by NPOL DRDO. It is a unified submarine sonar and tactical control system, which includes all types of sonar (passive, surveillance, ranging, intercept, obstacle avoidance and active). It also features an underwater communications system. The hull features twin flank-array sonars and Rafael broadband expendable anti-torpedo countermeasures.
Aridhaman will benefit from improvisation in many key sensors used in Arihant due to maturity of technology and will see improved ISS (Integrated Sonar Suite) along with USHUS sonar and next generation unified submarine sonar and tactical control system currently been developed by many DRDO labs in India.
INS Aridhaman will be India’s first SSBN which will be armed with 3500km longer-range K-4 SLBM which will be more China-centric weapons system rather then K-15/B-05 which was more Pakistan centric missile system and will play a key role in providing deterrence capabilities against China.
For years, the ministry of defence (MoD) has refused to acknowledge the existence of the base.
While the Arihant will naturally serve as a training platform for crews that will man its successor boats, just as the Chakra has been used to train the Arihant’s crew, like the latter it too will perform direct security missions. The Arihant’s reactor could be considered to be similar to late second generation VM series submarine reactors given acknowledged Russian assistance in this sphere. Such reactors needed refueling every 7-10 years at normal power consumption levels and the core lifetimes are sufficient for up to 5000 hours of journeying. This would be adequate for limited deterrence missions in potential patrol areas. Indeed, as the then IN Chief of Staff, Nirmal Verma stated in 2010, “India’s nuclear triad is there when it is commissioned,” indicating clear intent to mount deterrence patrols using the Arihant.
