The Valkyrie is one of the most insane jets ever made, in some ways more extreme than the SR-71. It was expensive, huge, dangerous to fly, and ultimately not particularly useful as a weapon because of ICBMs. But those are just minor reasons in the face of this:

* Length: 189 ft 0 in (57.6 m)
* Wingspan: 105 ft 0 in (32 m)
* Height: 30 ft 0 in (9.1 m)
* Wing area: 6,297 ft² (585 m²)
* Empty weight: 128,000 lb (58,100 kg)
* Loaded weight: 534,700 lb (242,500 kg)
* Max takeoff weight: 550,000 lb (250,000 kg)
* Powerplant: 6 × General Electric YJ93-GE-3 afterburning turbojet
* Dry thrust: 19,900 lbf (84 kN) each

* Internal fuel capacity: 300,000 lb (136,100 kg) or 46,745 US gallons (177,000 L)
