It was design to be used with paratroopers. Since no plane was big enough to take up a Russian tank, the russians decided to make a flying tank. I belive it would be tugged, then released and it would glide to its destination, where then it would land, release the wings, and then support the Paratroopers with armour support. I belive this did work, but by the time it came out, the russians were already at the Germans back doors.
