An account of the drill on a French defence-ministry website was promptly deleted, but too late for it to go unnoticed.

And, from the point of view of carrier-deploying navies, things are threatening to get worse. Saphir, launched in 1981, hardly represents the state of the art in underwater undetectability; in the decade since the Okinawa incident diesel-electrics have become even quieter.
