The Gremlins are coming! US military to test 'killer drone swarms'

They were the mischievous creatures blamed for causing mechanical failures and faults on aircraft during World War Two - before starring in a hit film as destructive monsters. Now, the gremlins are back - as a new type of killer flying drone. The US Defense Advanced Research Projects Agency (DARPA) research arm has revealed is planning to test the radical craft next year after awarding Dynetics a contract to build them. DARPA said the program has been deliberately named Gremlins after the imps that British pilots during Wold War Two adopted as their good luck charms. The program envisions launching groups of UASs from existing large aircraft such as bombers or transport aircraft - as well as from fighters and other small, fixed-wing platforms - while those planes are out of range of adversary defenses. When the gremlins complete their mission, a C-130 transport aircraft would retrieve them in the air and carry them home, where ground crews would prepare them for their next use within 24 hours.
