A 30,000 lb bomb is 15 Kilotons. The “Little Boy” bomb that exploded over Hiroshima in WWII was between 13 and 18 Kilotons estimated yield.
A 30,000 lb bomb is 15 tons. Math error.
A 30,000 lb bomb would be 0.015 Kilotons.
Only 0.006 Kilotons of this one are actual explosive.
Off by a factor of 1000. A 30,000 lb bomb is 15 tons, not 15 kilotons. A 170 Kiloton nuke actually only weighs about 700lb including the heat shield.
Wrong. Your decimal point slipped a bunch of places.
Fifteen Kilotons is 30,000,000 lbs. - 15,000 TONS of TNT.
This is 15 tons - and most of that is steel casing.
The MOP has more than 5,300 pounds of explosives, which is a little more than 2 tons. A 30,000 lb bomb is 15 tons or 15/1000th of a Kiloton. The MOP would be rated on the weight of the explosives, not the total weight of the bomb. The casing can weigh much more than the explosives. Some penetrators used hard tipped 8” howitzer barrels for casings, to ensure deep penetration into bunkers.
