Messerschmitt Me P.1101/99

        Another of the Messerschmitt P.1101 project series, the P.1101/99 is dated June 6, 1944.  The project management and overall design was overseen by Dip;.-Ing. Hans Hornung, who was also responsible for other Messerschmitt projects: P.1092P.1101 fighter , P.1112
        The fuselage was to be of all metal construction and contained the fuel tanks and most of the armament. 7650 liters (2021 gallons) of fuel could be carried in the fuselage tanks.   The wings were swept back at 45 degrees, with four Heinkel-Hirth He S 011 turbojets, each developing 1300 kg (2860 lbs) thrust,  buried in the thickened wing roots. Each pair of turbojets were fed by an air intake in the leading edge of the wing. The main landing gear retracted inwards into the fuselage, and the front gear retracted backwards beneath the cockpit. A two man crew sat staggered side-by-side in the cockpit, which was located in the extreme nose of the aircraft. Armament consisted of one 75 mm PaK 40 cannon in the nose and five MK 112 55mm machine cannon. Please see the table below for armament .
        This design was considered the ultimate attack and destroyer (Zerstörer) aircraft, and was expected to be in the air by 1948.  Because of the worsening war situation in Germany, the design did not progress past the initial design stage.
