Thacker) Organization: Eaton Semiconductor Equipment Division, Beverly, MA Lines: 22 Approved: military@att.att.com From: etnibsd!denbeste@uunet.UU.NET (Steven Den Beste) This kind of explosion seems to go completely against the philosophy which prevailed in the invention of the "blockbuster" bomb of WW-II. The concept went like this: A conventional surface explosion is very inefficient, since most of the power of the explosive goes into producing a shockwave. The blockbuster bomb was enormous, 6000 pounds or more, and had a delayed fuse and an armored nose. When it was dropped, it would hit the ground hard and keep going, burrowing down a hundred feet, and only then would it explode. This gave the explosion excellent "tamping", and almost all of the power of the explosion went directly into a shock wave in the ground. As a result, instead of merely breaking windows it shook all the buildings (or whatever) completely apart. Hence their nickname "earth-quake bombs". Does the gain from not carrying oxidizer in the bomb make up for the loss inherent in an atmospheric detonation?
