An electronic-warfare aircraft is a military aircraft equipped for electronic warfare (EW), that is, degrading the effectiveness of enemy radar and radio systems by using radar jamming and deception methods.[1]
In 1943, British Avro Lancaster aircraft were equipped with chaff in order to blind enemy air defence radars. They were supplemented by specially-equipped aircraft flown by No. 100 Group RAF, which operated modified Halifaxes, Liberators and Fortresses carrying various jammers such as Carpet, Airborne Cigar, Mandrel, Jostle, and Piperack.[2]
