1. Нортроп JB-1 "Бат" е крилата ракета земя-земя на САЩ, която е прототип на летящо крило с реактивен двигател. Програмата MX-543 на ВВС на САЩ е инициирана през септември 1942 г. за използване на лицензионни версии на реактивния двигател на Франк Уитъл (General Electric J31). Northrop Corporation е договорена в края на 1943 г. и са построени само 10 самолета JB-1. Пилотирана версия е изтеглена за първия полет на "27 август 1943 г.", от Роджърс Драй Лейк, а планерна версия е изстреляна от ракетна шейна и се разбива през декември 1944 г. Безпилотен JB-1, задвижван от импровизиран турбореактивни двигател General Electric B-1 с размах на крилата от 8,64 м, прави първия си полет от остров Санта Роза, Флорида, на 7 декември 1944 г. и се разбива на 400 ярда от релсовата ракета.

General Characteristics and Role
The Northrop JB-1 Bat was an experimental, unpiloted pulse-jet powered flying wing missile developed by the United States during World War II, based heavily on aerodynamic work done by the German Horten brothers. Its development was part of the United States Army Air Forces’ (USAAF) Jet-Propelled Missile program (JB). The JB-1’s design was highly unconventional, utilizing a pure flying wing configuration with twin rudders and a very clean aerodynamic profile. It was intended as a short-range surface-to-surface cruise missile that could carry a massive warhead (comparable to the German V-1 flying bomb). The project was ultimately terminated due to propulsion issues and the end of the war, but it significantly contributed to Northrop’s pioneering work on tailless aircraft.

Propulsion and Launch Method
- Engine: 2 x General Electric BQ-7 (pulse-jet engines).
- Thrust (Total): Approximately 4.45 kN (1,000 lbf).
- Maximum Speed: Designed for high subsonic speeds.
- Launch Method: The JB-1 was designed to be launched from a rocket-powered sled running on a fixed railway track, similar to the method used for the German V-1 missile.
- Propulsion Issues: Initial tests with the pulse-jets were unsuccessful due to performance and reliability problems, leading to a modified glide-only prototype being tested first.
Legacy and Further Development
- Pilot Modification: After the failure of the pulse-jet system, the design was briefly converted into a piloted glider (designated JB-1A) for aerodynamic testing, including a side-by-side cockpit, which helped validate the flying wing concept.
- Follow-on: The JB-1 project provided valuable data that directly influenced Northrop’s later, larger flying wing aircraft, such as the XB-35 and YB-49 bombers, and eventually the B-2 Spirit stealth bomber.
- Termination: The program was cancelled shortly after the end of the war, as the need for the short-range missile rapidly diminished, allowing resources to be shifted to long-range missile and bomber programs.
