The Me 262 was faster, and more heavily-armed than any Allied fighter, including the British jet-powered Gloster Meteor.[6] One of the most advanced aviation designs in operational use during World War II,[7] the Me 262 was used in a variety of roles, including light bomber, reconnaissance, and even experimental night fighter versions. Me 262 pilots claimed a total of 542 Allied kills,[8] although higher claims are sometimes made.[Note 1] The Allies countered its potential effectiveness in the air by attacking the aircraft on the ground and during takeoff and landing. Engine reliability problems, from the pioneering nature of its Junkers Jumo 004 axial-flow turbojet engines—the first ever placed in mass production—and attacks by Allied forces on fuel supplies during the deteriorating late-war situation also reduced the effectiveness of the aircraft as a fighting force. In the end, the Me 262 had a negligible impact on the course of the war as a result of its late introduction and the consequently small numbers put in operational service.[10] While German use of the aircraft ended with the close of the Second World War, a small
