In Feb this year, the Indian Navy posted a pic of people yoga-posing on board INS Subhadra. Boffins at Federation of American Scientists (FAS), a US non-profit that tracks movement of the world’s nuclear arsenal, spotted the pic and noticed that Subhadra’s deck no longer has missile stabilisers needed for launching nuclear missiles. This meant, FAS reckoned, that at least some Dhanush nuclear-capable missiles had been shifted to submarines – and, more importantly, that INS Suvarna is currently without nuclear missiles-launching capability. The sort of info you’d hire a spy to get but you can now get by simply seeing publicity pics of people doing yoga on board an Indian Navy ship.
