– Economist – Rarely does nemesis follow hubris so quickly. On August 10th India’s prime minister, Manmohan Singh, proudly announced that the reactor of the country’s first indigenously designed and built nuclear-powered submarine, the Arihant (“Destroyer of Enemies”), had been activated and the vessel would soon begin sea trials. This “giant stride” was quickly followed by another, two days later, with the launch of the country’s first domestically built aircraft-carrier, the Vikrant, which is expected to enter service in 2018. But in the small hours of August 14th an explosion on board an Indian navy submarine berthed in Mumbai killed 18 sailors. The vivid explosion that lit up the city swiftly eclipsed the earlier, patriotic glow, bringing to a premature halt all the celebrations the admirals had intended.
