India has a new nuclear-capable ballistic missile submarine. But can it catch up with China?

CNN —

India’s second nuclear-capable ballistic missile submarine joined its naval fleet late last month, a move the government says strengthens its nuclear deterrent as New Delhi casts a wary eye at both China and Pakistan.

But India is still playing catch-up, at least compared with China, as the People’s Liberation Army grows its fleet – as well as its land and air capabilities – amid simmering tensions along their shared border.

The nuclear-powered sub, INS Arighaat – “Destroyer of the Enemy” in Sanskrit – will “help in establishing strategic balance” in the region, Indian Defense Minister Rajnath Singh said at an August 29 commissioning ceremony at Visakhapatnam naval base, the headquarters of India’s Eastern Naval Command on the Bay of Bengal coast.

That balance currently tilts in favor of China, with the world’s largest navy by numbers, including six operational Jin-class nuclear-powered ballistic submarines that outclass India’s two – Arighaat and its predecessor in the same class, INS Arihant – in firepower.

The Chinese subs can carry a dozen ballistic missiles with ranges of at least 8,000 kilometers (4,970 miles) and have the ability to carry multiple nuclear warheads, according to the Missile Defense Advocacy Alliance, a non-profit organization promoting the development and deployment of missile defense for the United States and its allies.
