Feuerlilie
Feuerlilie (English: fire lily) was the code name of a German anti-aircraft missile, which was developed in 1940 and was shelved because of problems with the controller and the drive section at the end of January 1945 in favour of other projects. The Feuerlilie was built and tested at Rheinmetall-Borsig in two versions: the F-25 with a diameter of 25cm, and the F-55 55cm in diameter. The engines were Rheinmetall 109-505/515 solid rockets.
