Boeing X-37C Manned Mini-Shuttle (2011)
About the Design
The X-37C is Boeing Aerospace's proposed mini-shuttle for transporting crews to and from the International Space Station. The design is basically an upscaling of the company's successful X-37B reusable orbital test vehicle (OTV), which the U.S. Air Force has been using for a number of top-secret long-duration missions.
The principle differences between the X-37C and the X-37B -- in addition to its size -- are the forward cockpit windows, the upper fuselage observation windows, the addition of a second engine bell and, perhaps most important, a docking collar at the rear of the vehicle that would allow it to mate with the ISS and permit direct vehicle-to-vehicle crew transfers.
To date, the X-37C has not progressed beyond the proposal stage.
About the Kit
The X-37C kit was created for Fantastic Plastic Models by BLAP! Models and Paul Roberts based on several Boeing Aerospace designs.
