On April 29th, 1945, a few days before the end of the war, when the American army discovered the secret factory, P.111 V1 was about 8% completed. The fuselage is made of hard aluminum alloy, and the air inlet passes under the cockpit. Above the engine and behind the cockpit is a 1-liter fuel tank. The rear fuselage gradually shrinks into a cone, which is equipped with radio equipment, oxygen supply equipment, navigator and gyroscope. The lower surface of the rear fuselage is covered with steel plate to avoid the high temperature of the nozzle. Although the prototype is planned to install Jumo 4B jet engine, a more powerful He S 11 engine will be installed in a later version. The wing is basically the same as Messerschmitt Me262 from the engine (rib frame 7) to the terminal (rib frame 21), including ailerons and leading-edge slats of Me262. The second wing was assembled in February 1945, and the leading edge slat was extended by 13% to 2%. The wings are covered with plywood, and the ground can be adjusted to a sweep angle of 35, 4 or 45 degrees. The two horizontal tail and vertical tail are also made of wood, and the rudder can be deflected by 2 degrees. T- tail and V- tail are also designed. The landing gear is the front three-point type. The nose wheel is retracted and can be driven. The main wheel with braking device is retracted forward. The cockpit is located in the nose, and the bubble hatch provides an excellent view. The warm air hatch cover from the engine does not fog. The production type has two or four MK 18 3mm guns and cabin pressurization. The production type is also equipped with cockpit armor, and four X-4 air-to-air missiles can be hung under the wing.

a few days before being discovered by the allied forces, Messerschmitt packed all microfilm, calculation and design documents of engineering drawings in watertight containers and hid them in four locations in the surrounding villages. Sunday, April 29th, 1945. American infantry entered the secret factory to seize some documents and destroyed many Axis documents. The unfinished prototype of Me p.111 V1 was also found nearby and dragged out of the hidden tunnel. Within days of Germany's unconditional surrender, American experts had arrived to assess the importance of seizing the secret factory of Messerschmitt. Afterwards, I asked some employees of Messerschmitt to try to retrieve the lost documents. When the American team tried to recover these hidden microfilm files, the French army had recovered some files.

Robert J. Wood of American research group, Bell Aircraft Company. He and Wodema, the chief designer of Messerschmitt, tried to lobby members to complete the prototype of Me P.111 V1 in June 1945. This proved impossible, because in fact most of the design documents are now in France (they refused to enjoy them in time), while other key information was destroyed. The prototype was destroyed by American soldiers and curious photographers because it had been parked in the open air.

in August p>1948, new york, Me P.111 V1 was shipped to Bell Aircraft Company in Buffalo. There was more damage when the plane was loaded, and there was virtually no possibility of repair and flight test. P.111 was later equipped with Allison J-35 jet engine, and the weapons (6 x Mg 151 and 4 x MK 18 guns) were symbolically installed on the side of the fuselage. Bell developed X-5 based on Me P.111, during which P.111 was used for static inspection. In the early 195s, the remaining part of Messerschmitt, Me P.111 V1, was sent to the airplane cemetery, thus ending the history of this unique airplane.
