A Westlnghouse device, known as KEMPSTER A, which will generato an electron cloud that can absorb radar frequencies, has been mounted in1 and performance testing has been started. The preliminary findings of two flight tests indicate that the equipment performed as planned. Additional tests are necessary to ascertain the optimized potential of the
