B-70 Valkyrie

Next for Pen and Sword and coming out later in 2011 is a complete change of tempo - I thought it was about time I did one of Cecil the sea-sick Sea Serpent!

The first time anyone sees the sole surviving XB-70A Valkyrie it’s hard not to be struck dumb by the jaw-droppingly amazing shape of this totally futuristic other-worldly looking aircraft.
Firstly, it’s huge. The aircraft is five times heavier and a whole lot larger than the MiG 25 Foxbat or SR-71 Blackbird , the design’s nearest rivals. Secondly it looks fast. The first time I saw Air Vehicle One was outside the USAF Museum (as it then was) at Wright Field, near Dayton Ohio, in 1980 - it looked as if it was about to go supersonic just parked there! At the time it was playing one of a pair of ‘bookends’ outside the main building to a later generation Rockwell B-1 ‘Bone’ and the Valkyrie still looked the more advanced!
Thirdly, the aircraft was one very big leap-into-the-future design that pushed the envelope in terms of exotic materials used - such as stainless steel honeycomb, very large amounts of titanium, the use of tool steel for structural components and it would have used the chemical high energy ‘zip’ fuel if that had not been cancelled.
At one stage - if all the plans and rhetoric had come to fruition - there would have been 250 Valkyries in the air - the pinnacle of General Curtis LeMay’s quest for the ultimate strategic bomber operated by his Strategic Air Command.
It has been said that the beginning of the XB-70 story was the search for a nuclear-powered bomber - that started with a highly modified Consolidated B-36 Peacemaker, the design of which came from World War Two when it looked as if the USA would have to fight a two front war from bases only on the mainland. The B-36 was the first interim bomber, replaced almost as soon as it appeared by the Boeing B-52 Stratofortress, itself the second interim design, albeit jet-powered, but it was still subsonic.
The Convair B-58 Hustler came out of the preliminary studies and was supersonic - but at best it could only be called a medium bomber and was too much, too soon. It became a maintenance nightmare, as any crew chief from the time will tell you.
What General Curtis LeMay wanted was a machine with the speed of the B-58 and the load-carrying capacity of the B-52 - and without doubt the B-70 looked like it would fulfill his needs. What LeMay got was possibly the biggest fight he ever had experienced - with Robert McNamara and his team of ‘Whiz Kids’. This small, elite band of civilians, who had mainly moved over from either the RAND Corporation or the Ford Motor Company and went right to the heart of the John F Kennedy  and Lyndon B Johnson presidential administrations. The Whiz Kids invented a world where all decisions could be made based on numbers - an ideal that is still skirted on by many MBA programs and consulting firms. They found power and comfort in assigning values to what could be quantified and deliberately ignored everything else.
The B-70 was cut back to two experimental aircraft - with the possibility of a further machine, as a prototype to the ‘Reconnaissance Strike’ concept. It was also to be used as a test aircraft in the American ego-driven ‘Mach number too far’ SuperSonic Transport  that was doomed to failure.
Of the two built, one was lost - and two highly experienced test pilots were killed - during what politicians called an illegal flight, despite the same type of event happening many times before.
The revealed story is one of ambition, dreams, spying, and dirty pool politics on Capitol Hill – so nothing unusual there then!
‘Cecil the sea-sick sea serpent’ may have been one of the silliest nicknames ever given to an aircraft, but what an aircraft, what a shape, what a design!
