JB-10 Experimental stroke UAV

Developed in 1944, the cruise missile JB-1A on the application should resemble the German Fau-1, however, exceed its performance. After several years of "Northrup" and was unable to complete the first draft. Though this idea is the military has a strong interest, studies have not been performed successfully. The first unmanned due to improper engine could not fly to the desired height. Temporarily shut down the project, but the idea has not been abandoned. After a while, company representatives said the US Air Force to modernize the JB-1.

The new model possessed a relatively large indicator of the range of flight and the power of air bombs. The unsuitable engine was replaced by a more suitable Ford company. It was cheap, stable and reliable. He was placed inside the fuselage, as a result of which the shape of the fuselage increased. Also, in addition, it was necessary to install an annular air intake, which provides additional cooling. Air bombs were placed not under the wing, as in the analog, but directly into the wings. In the air, JB-10 rose in 1944 year. Although it had a primitive guidance system, it was still relatively better than the German cruise missile. The UAV was increased the radius of flight, speed, installed more powerful air bombs.

By the year 1945 10 flight tests were carried out, but only 2 of them were successful. Therefore USAF abandoned their application in the former Japanese military campaign. An additional negative factor that influenced the closure of the project, was the end of the Second World War.
