Manufacturer's Designation: McDonnell-Douglas. Class: Manned. Type: Spaceplane. Nation: USA. Agency: NASA. Manufacturer: McDonnell-Douglas.

The most radical modification of the basic Gemini reentry module ever proposed. Drawing on the results of the ASSET subscale winged reentry vehicle program, McDonnell proposed a version of the spacecraft using the same internal systems but capable of a piloted runway landing. The spacecraft was designed for launch by the standard Titan 2 Gemini Launch Vehicle. Unlike the ballistic Gemini, winged Gemini was not designed to maneuver in orbit (launch on a Titan 3A or 3C with a transtage would be required for that capability). Separation from the launch vehicle was made by 2 x 260 kgf solid motors; attitude control in orbit was provided by 8 x 45 kgf bipropellant thrusters at the base of the vehicle; retrofire was initiated by 5 x 1165 kgf solid rocket motors.

The Gemini propulsion systems contained in the basic Gemini retrograde and equipment modules would be repackaged within the jettisonable adapter section of the spacecraft. Five instead of four reentry rockets were required for retrofire due to the increased mass of the return vehicle. Swing wings would be deployed after reentry to allow for a runway landing.
