Fotografie + English: Loon JB-2 (US V-1 Buzz Bomb) (Taken on October 13, 2018, Canon PowerShot G16)

• White Sands Missile Range Museum (Doña Ana, New Mexico, United States)
• Loon was the American version of Germany's V-1 Buzz Bomb, essentially a cruise missile. In 1944, The U.S. Army acquired an unexploded German V-1 (Fieseler Fi 103) and decided to mass-produce a copy as the JB-2 (Jet Bomb 2).
• The JB-2 was identical to the V-1 except for the launching method and the guidance system. Because the pulsejet only worked efficiently in forward flight, the missile had to be boosted into the air. The Germans' catapult was replaced by a ramp and a rocket booster for the JB-2.
• The German V-1 used a primitive guidance method, by which the pulsejet was stopped after a preset time and the missile dived onto the target. Because this was extremely inaccurate, the JB-2 used radio command guidance. It was equipped with a radar beacon to facilitate tracking, and a remote control operator could send guidance commands for course corrections and to initialize the terminal dive. While significantly more accurate than the original system, the average error rate was unacceptable.
• In late 1944, the Army planned to procure 75,000 JB-2s. However, the war ended and only about 1400 were built. The Air Force and the Navy used them as test vehicles for guided missile launch technology. As such, they were redesignated LTV-1 by the Air Force, while the Navy briefly called it the Loon. Only one was ever fired at White Sands Proving Ground and that was in 1953 by the Navy, designated KUW-1 research vehicle
