We BRING COMPANIES and CUSTOMERS TOGETHER

is over. "A lot of these [carrier-killing] systems are essentially unproven," says Nick Childs, an expert at the International Institute of Strategic Studies, a London think-tank. A missile that can fly the distance required is only one part of such a system. You also need eyes that can keep track of the prey. Ground-based radar cannot see targets hundreds of kilometres out to sea. Satellites can help, but they don't give you data of high enough quality for the necessary precision, says Sidharth Kaushal, an expert at rusi, another London think-tank. "They can tell you roughly where a carrier is, and possibly its bearing". Bringing together different sorts of satellite and drone data to update targeting information on the fly will not be easy, not least because the target carrier's bearing is unlikely to stay steady. Satellites can spot missile launches, too—and the Ford could travel more than four nautical miles in a new direction during the eight minutes it would take a df-21d to reach it.
