Nuke-Lobbing

SlideGuitar writes "The following is a fascinating article about how the Navy in the 1950s, wanting to assure that it had a carrier based nuclear force, used A1 Skyraider (single engine propellor driven aircraft) to lob nuclear bombs using a manuever called the "goofy loop" (read the article.) The goofy loop put about seven miles between them and a Mark 7 nuclear device at detonation. The pilots knew that (1) they couldn't get far enough away to survive, and (2) if they did survive there probably wouldn't be a carrier to go back to anyway. There are lots of emails from pilots who did the manuever and what they thought about the whole business."

    I have heard of "lobbing" before. If you know the speed of the plane and the angle of the climb, it should be easy to calculate the distance of the "lob". The problem is that it is difficult to repeat the exact conditions repeatedly. One lob might be 7 miles, then next might be 7.5 miles.

    I know some of you don't think that a few thousand feet would matter for a nuke, but most smaller tactical nukes are used to take out a specific target. The yeild can be as low as a few hundred kilotons or as high as a few megatons. Missing a deep bunker by a few hundred meters with a low-yeild nuke would mean a lot of collateral damage with almost no effect on the target.

    If you are interested in reading more about tactical mukes, do a google for B-61. These are what the Air Force uses today. Or would have/will use(d) in the proper situation. I think the original design purpose was to drop on formations of Soviet tanks in the event they mobilized on Western Europe.

      I live in Japan. I have visited Hiroshima. Having a nuke dropped on you is NOT the end of life as you know it. You just bulldoze the contaminated waste away and rebuild. With a modern nuke, you wouldn't even have to bulldoze the topsoil, just wait for a bit and the level would drop rapidly.

      Dropping a nuke in a cave in Afganistan would be even less a problem. Just cordon off a area in the desert and leave it for a few years.

Now it simply means you don't like Bush and therefore shouldn't be listened to. People who do favor Bush are never partisan.

    OF COURSE the war in the middle east is about oil. More to the point, it's about protecting the supply of a strategically essential resource.

    I've been trying to figure out for a long time what the motive for this war really is. The official reasons given (9/11, WMD, "he gassed his own people", bringing democracy to the nations in the region, etc.) either make no logical sense, are obvious lies, or are so outlandish that it's clear nobody in the administration takes them seriously.

Inflation. Deflation. No matter what it was, the tax cut was going to fix it. The war was the same way. It's always pretty clear what the Bush administration wants, but they never indicate why they want these things. I do know two things about the true motive of the war:

    • It has something to do with Israel.
    • It has something to do with oil.

    I can at least understand a war designed to undermine OPEC. Why didn't Bush just flat out say it? "We want to invade a country so we can gain access to its oil fields." Spare me the bullshit about WMD, the war on terror, spreading democracy, etc. When a president lacks the political balls to announce to the world why he's starting a war, it's usually a sign that the war is a bad idea in the first place.

      Lofting is a standard maneuver, and it is not restricted to just nuclear weapons. It's used whenever the pilot wants to add some sort of stand-off capability to a non-stand-off weapon, and requires only that the aircraft have a CCRP (continuously calculated release point) bombing mode (which includes all current U.S. fighter and bomber aircraft). Again, it has nothing to do specifically with nukes.

      Here's how it's done; the pilot waits until the horizontal line on the CCRP vertical line blinks, indicating he's within maximum range. Then he increases pitch to 45 degrees and pushes the throttle to mil or afterburner if he's got the fuel. He then holds down the pickle, and the bombing computer releases the bomb once it detects that his aircraft is in a correct firing solution for a successful loft.

With the advent of parachutes to slow down the bomb drop rate and delayed-action detonation circuits (both of which were developed for the B28, B43, B57, B61 and B83 bombs due to the fact bombers dropped the bombs at very low altitude at high speed), LABS manuevers are fortunately not necessary nowadays.
