Calculations are made for 1000-lb and 64,000-lb cylinders of H-6 

 explosive (L/D = 3.65) fired end-on, 1.3 diameters from the water 

 surface. By assuming a uniform fish-density distribution throughout 

 the water it is estimated that on the basis of fish-killed/ kg 

 explosive a typical underwater explosion is some 1000 times more 

 hazardous for killing fish than these air-burst tests.
