How India, too, is on a quest for undersea dominance, to counter the Chinese navy’s growing presence

Abhijit Singh says as China and the US pursue development of unmanned underwater drones, the Indian navy is also adjusting its strategy to include autonomous vehicles in its armoury against China’s growing undersea footprint in the Indian Ocean

Undersea warfare has come to the surface after the South China Morning Post reported on Beijing’s development of giant, smart, cheap unmanned submarines. The “sea bots”, operated by artificial intelligence, are intended to perform tasks as diverse as reconnaissance, mine placement and making self-destructive attacks. They are now undergoing testing at a facility in Guangdong province, and will be part of a network of manned and unmanned assets tracking rival submarines in the world’s oceans.

China isn’t alone in its quest for undersea dominance. Last year, the United States commissioned its first-ever squadron of unmanned underwater vehicles, or drones, and contracted top defence firms to produce a new generation of such machines. It aims to enhance its combat potential, including in anti-submarine, mine clearance and even counter-underwater drone operations.

Deep-sea drones are not exactly new, but have recently come to the fore as potential replacements for conventional submarines. Military experts say a technological revolution in undersea warfare is making the maritime environment increasingly transparent. Lower frequency active sonar and non-acoustic detection methods are making it hard for submarines to hide by keeping quiet.
