The conventional wisdom in the game is that it takes 2X1000lb bombs and 6 U.S. 5" rockets to drop a hangar.
Doing some reading, I saw that the warhead size on the U.S. 5" rocket was 55 pounds of HE. Overall weight of the entire rocket was 140 lbs.
6 X 55 = 330 lbs. of HE. If that's the case, then it should take more than six rockets to finish off a hangar (given the default object setting for a hangar), after the crowd pleasers do the heavy lifting.
So, in game, are we getting credit for the kinetic energy or is the warhead damage equal the 140 lbs of the entire rocket?
