The forward half of the bomb is a giant iron casting filled with kerplosive. You wouldn't want spars running through that, I suppose, especially if you're trying to *not* modify existing hardware, or if you don't want to mess with the armor-piercing forward penetrator. With these forward swept wings, the spars are far enough aft that they fit through the non-kerplodey rear shell of the bomb, and are apparently part of a new structure.Interesting. Why inverted wings? To allow for supersonic glide?
May be one model of Tallboy/Grand Slam" family .but wath as bomb,the built year and the spcefications and so on.For the moment mystery we have just the name Bell.
It's clearly in the "Tallboy/Grand Slam" family. The squared-off tailfins seem to be those of the T-12 "Cloudmaker," 43,000 pound bomb. The T-12, however, had four tailfins not three.
