The Me 262 Schwalbe (Swallow) was the first operational jet fighter. Design and testing of the first German jet engine was well underway even before World War II started. Due to problems encountered with new materials needed, fatigue and German High Command intervention and delays, the aircraft did not see operational flying until April 1944. The Me 262 was highly maneuverable and faster than any other aircraft of the time, but continued to suffer from engine problems. Many aircraft were lost to engine problems or mishandling.
Me 262B-1/U-1 was a two seat trainer converted into a night fighter, with the addition of a FuG 218 Neptune radar. This was an eight-dipole antenna array mounted on the nose of the aircraft.
