India’s nuclear subs – The Curse Continues

January 5, 2013: The Indian Navy made public its efforts to get critical (but unnamed) replacement parts for the nuclear submarine (INS Chakra) it received from Russia last January. India has often had problems getting parts or other forms of service for Russian weapons. The Indians are no longer inclined to play nice with the Russians on these matters. President Putin of Russia promised to sort this out quickly.

INS Chakra was formally the Nerpa, a Russian Akula II class submarine that was supposed to be turned over to India (which is leasing it) three years ago. The main reason for the delay was a safety issue. Four years ago, during sea trials, there was an equipment failure that killed 20 sailors and shipyard workers aboard the Nerpa. This delayed sea trials for many months and the Russians found more items that needed attention. These additional inspections and repairs continued until quite recently. India is paying $90 million a year for ten years to lease the Nerpa, an 8,100 ton Russian sub that was then renamed INS Chakra (the same name used by the Charlie class Russian sub India leased from 1988-91) by the Indians.

There have been many reasons for getting this sub from Russia. Back in 2010 the Indian crew, after more than a year of training, found that they were not fully prepared to take over the sub. The crew required another six months of training. The Russians were being blamed, partly because they were in charge of the training and partly because they recently made a lot of internal changes to the Nerpa. But Indians also admit that all their veteran nuclear submarine sailors (who manned a leased Russian nuclear sub from 1988-91) were retired and the difficulties of learning how to run a nuclear boat were underestimated.

The Nerpa was built for this Indian deal and finally completed its sea trials and was accepted into Russian service in late 2009. India was supposed to take possession in May 2010, but there were more delays, mainly because of the accidental activation of the fire extinguisher system and death of twenty on board. There were 208 people aboard the sub at the time, most of them navy and shipyard personnel there to closely monitor all aspects of the sub as it made its first dives and other maneuvers. The source of the fatal accident was poor design and construction of the safety systems. This accident led to sailors and shipyard technicians being fearful of going to sea on the boat. So the sea trials were delayed, even after repairs were made.

The post-accident modifications on the Nerpa cost $65 million. The lease arrangement has India paying $178,000 a day, for ten years, for use of the sub. The 7,000 ton Akula II requires a crew of 73 highly trained sailors. Over a hundred Indian sailors have undergone training to run the boat.

It was Indian money that enabled Russia to complete construction on at least two Akulas. These boats were less than half finished at the end of the Cold War. This was another aftereffect of the collapse of the Soviet Union. Several major shipbuilding projects were basically put on hold (which still cost a lot of money), in the hopes that something would turn up. In this case, it was Indians with lots of cash.

Traditionally, when a new ship loses a lot of people during sea trials it is regarded as “cursed” and unlucky. Sailors can be superstitious, especially when there are dead bodies involved. It’s not known if India will have any problems with this.

India has designed and built its own nuclear sub but the first one is basically a development craft, and mass production of Indian designed nuclear subs is still 5-10 years away. The unlucky Russian sub will enable India to train more nuclear sub sailors in the meantime.

Indian nuclear submarine INS Chakra facing problems with critical components:

India’s only Russian-origin nuclear submarine INS Chakra is facing problems with its critical components affecting its operational readiness.

The 8,000-tonne submarine has been facing problems with its critical components and Russia has been asked to provide the parts for the vessel which need to be replaced, Navy sources said.

However, they did not divulge the components which would have to be replaced but indicated they are critical for the operations of the submarine. India had inducted the Akula-II Class ‘Nerpa’ nuclear submarine in its inventory in April this year at the Vishakhapatnam-based Eastern Naval Command. It was renamed ‘Chakra’ by the Indian Navy.

The Russian submarine had met with an accident in November 2008 when it was undergoing sea trials in the Sea of Japan in which around twenty sailors were killed and several others were left injured.

The submarine was launched in 1993-94 but its construction was held up since then due to lack of funds with the Russian Navy.

However, in 2004, the Russian side decided to build it after reaching a ten-year lease agreement for operation of the submarine with the Indian side.

With INS Chakra and the yet-to-be-inducted indigenously built INS Arihant, India is planning to have two nuclear submarines guarding its vast maritime boundary. With a maximum speed of 30 knots, Chakra can go to a depth of 600 metres and has an endurance of 100 days with a crew of 73. However, as per the lease accord, it cannot carry nuclear warheads.

The vessel is armed with four 533mm and four 650mm torpedo tubes. India had leased and operated a Charlie-class Russian nuclear submarine, also called ‘Chakra’, in 1988 for training its personnel on such submarines.
