What aircraft, as originally proposed, would not have any landing gear, a feature which would result in a great weight saving. Takeoffs would be facilitated by a jettison-able three-wheeled cart that left the aircraft as soon as the plane was airborne.
Landing the aircraft was facilitated by retractable skids (into the fuselage and engine nacelles). The first-built aircraft used the cart for takeoff and the skids for landing.
The aircraft was originally missioned as a reconnaissance plane, later fitted with bomb racks, both external and internal. Just to confuse you more, because of its excellent performance, it was also tested as a fighter, but the war ended before that version was available.
