XB-70 Vs. Original B-70?

Fri Oct 15, 2004 1:01 pm

By what the XB-70 (which by the way is f*ckin huge!) looked like, anyone should be able to see there is nearly no practical room for payload, the engines take up the entire undersurface profile. The XB-70 shape might have been for pure experimentation. What about the original B-70 plane, how could it have gone Mach 3 with a payload?

The meaning of life is curiosity; we were put on this planet to explore opportunities.

Actually I think there was provisions for a B-29 sized bombbay between the engine ducts.

During the test program it oddly enough held test gear.

One of the reasons it was axed, it could only eject free fall nukes out of a bomb bay, presumably do recce too, but the SR-71 had that covered.

Look at the shape, what a huge radar target, it's very impressive performance might have made a SA-2 hit difficult, but not a SA-5, of course the threat of the B-70 compelled to USSR to build a quick and dirty response in the shape of the Mig-25.

A fabulous aircraft, deviod of a mission, stand off weapons on B-52s, ICBMs, SLBMs all sufficed, unlike the B-52, the B-70 was not suitable for adapting to conventional missions.

The XB-70 had a bomb bay forward of the engines. The engine duct work wrapped around it. The doors would slide backwards instead of opening like a clamshell.

I am curious if the test program ever progressed to doing any test drops.

It has long been the showpiece of the, now titled, National Museum of the United States Air Force. The nose boom does appear to be sagging a bit since it was delivered to the museum in Feb 1969.

Here is a link to the museum's web page on the Valkyrie: http://www.wpafb.af.mil/museum/research/bombers/b5/b5-67.htm

If you go on to the NASA DRYDEN website they have film footage of the XB-70 in test operations the Films have no sound but show all the Subsonic parts of the test flying and are in Colour they are also down loadable!

Actually saw one of these in flight once. It was in July, August or early September 1965. We were at Fort Ord, near Monterey, California and it was making a turn overhead, back down toward EDW.

It served one great purpose.

It may have been the single most beautiful thing man ever made from metal.

Go to the Dryden site and download the picture of it in high altitude flight. The sky is blue-black and the underside of the plane is lit light blue by Earth's albedo. So cool!
