It was designed by the Škoda-Kauba industries towards the end of World War II as part of the Third Reich defense effort against the devastating allied bombing raids.
Engineer Eugen Sänger worked on this René Lorin ramjet fighter project after his Silbervogel proposal for a suborbital glider to the Reich Air Ministry was rejected.
[1] The Škoda-Kauba Aircraft Industries, located in a suburb of Nazi-occupied Prague,[2] designed the SK P14 as a single-seat monoplane powered by a Sänger ramjet engine.
Since the ramjet had a diameter of 1.5 m and a length of 9.5 m, the massive engine and its tubular air-intake duct formed most of the fuselage structure.
In order to bring the ramjet to a speed where it would work, take off was by means of booster rockets fitted to a three-wheel detachable dolly.
