The Lippisch P.13a was a project for an experimental German WWII fighter. The drive was to be provided by a single Kronach Lorin jet engine. The deck armament was supposed to consist of heavy machine guns with a caliber of no more than 12.7 mm. The machine has never been tested, much less entered mass production. From the very first project, the Lippisch P.13a was an incredibly avant-garde and innovative machine. First of all, it was characterized by the use of a delta wing and an extremely unconventional fuselage without a fin. It was also supposed to be a very small and light aircraft weighing less than 2,300 kilograms. Moreover, from 1944, it was planned that the Lippisch P.13a would be powered by coke, which was a solution unheard of in the previous Luftwaffe aircraft. Despite many unusual solutions, tests in the wind tunnel showed considerable stability of the machine at very high speeds. However, this avant-garde construction was never realized and only its models were created.The Lippisch P.13a was a project for an experimental German WWII fighter.
