The Horten H.XIII was an experimental flying wing aircraft designed by the Horten brothers during World War II.




Design


The H.XIIIa was an unpowered glider with wings swept backwards at 60°. It was a technology demonstrator to examine the low speed handling of highly swept wings, for the development of a jet fighter which was expected to exceed Mach 1, the H.XIIIb.
