JB-2 Loon/V-1

The sign accompanying this buzz bomb indicates that it's an American-made copy of the German V-1, the JB-2 Loon, but subtitles it a "V-1 'Buzz Bomb'". Oddly enough, the artifact bears German-language markings.

To side-step these ambiguities, I'll just refer to the artifact as a "buzz bomb," because that should adequately describe either version of the artifact.

Right next to the buzz bomb is a partially-disassembled pulse jet engine.

The Air Force Museum's web site has a number of V-1-related images, including a cool cut-away diagram of a V-1, a photo of a V-1 launch emplacement, and a picture capturing a V-1 moments before impact. The Smithsonian has a detailed V-1 page (be sure to click the "Long Description" tab).
