The concept was to have a transport that would be able to carry interchangeable pods (sound familiar, Thunderbird fans?) and was tried years later by other aircraft manufacturers.
The concept never got past the scale model proposal stage.
Cool vid, Geo...that Ta400 actually looked like they were onto something, but like most things Luftwaffe, took too long, was too little and much too late...
Speaking of which, here's a wind tunnel model of Lippische's P12 fighter concept.
Originally designed as a twin-boom pusher with the designation XP-52, the model 16 was intended to have a contra-rotating propellor in a pusher configuration driven by a Continental XIV-1430-5 inverted V-12. It was to have two 20mm cannon in the nose and six .50 MG (3 in each boom leading edge).
With the delays in the V-12 engine, Bell's engineers turned to the P&W R-2800-23 engine and started a modified project based on the XP-52, designated the XP-59. So the XP-52 was cancelled on 3 November 1941 and the Model 16 project continued on as the XP-59. Two prototypes were ordered, but the project was cancelled before they were built. The XP-59 designation was eventually given to the P-59 jet project.
Shown is the Model 16 (XP-59) mockup at Bell's facility:
