In 2009 Northrop Grumman completed its full-scale (non-powered) replica of German Horton 229. RCS measurement tests were conducted at Northrop's remote test facility in Tejon Ranch, northwest of Lancaster, California.

In the late 1930s, Germany produced several prototypes of flying wing aircraft.
In 1943, the Horton Brothers test flew their Ho. 229 in Germany.

Purportedly it had a ram-jet engine and could achieve speeds approaching 600 miles per hour. It was not intended to be stealthy.
Although we cannot over exaggerate the capabilities of Ho. 229,

In 1949, Northrop itself produced their own version (YB-49) of the flying wing, test flew it but basically it ended up in a rather dismal failure.
Some say that Northrop intentionally produced the ridiculously powered YB-49 as a disinformational "cover" for the real Ho. 229, which, according to some, was test-flown in 1947 near White Sands, New Mexico and crashed somewhere.....although this scenario is highly unlikely.
