The Germans had a disc that flew though not at any hyper-performance levels.—
BMW
A flying disc was conceived by BMW engineers led by a Dr. Miethe near Prague. The Flugelrad V-1 used a BMW 003 with 4 deflection blades for a power source but most other details are unknown. That engine would hang underneath the disc and provide thrust and deflection blades would give directional stability as they spun.
Diameter was penciled out at 19.6 feet with a height of 7.2 feet. Weight was foreseen at around 6,600 lbs. A single pilot position was drawn in at the center of the disc. No armament was stated.
The Flugelrad V-1 was built in 1943 and made its first flight sometime in the Fall of that year at the Prague/Kbely airfield. The Idea behind this odd looking aircraft, was the use of deflection of the exhaust gases from a BMW 003 turbojet upwards to make a 12 bladed disc spin at up to 1,800 RPM. At the same time the exhaust was redirected backwards changing the pitch of the discs blades so it would take off VTO-style and then fly like an autogyro.
What became of the prototype is unknown. Only blueprints and drawings are left now but this craft once existed and flew.
