TEST A: EXPLOSION IN AIR 



in several places and badly buckled. The port corner 

 of the flight deck was blown oft'. Part of the deck 

 planking was burned away. All four stacks were de- 

 molished, the flight deck crane was knocked over, and 

 both airplane elevator platforms were blown overboard. 

 Antenna masts were bent or broken. A fire broke out 

 on the hangar deck, adding to the wreckage already 

 produced by the shock wave. Huge vertical beams of 

 heavy gage steel had been ripped loose; in some 

 instances they w^ere left hanging in grotesque array. 

 Her plating above the waterline was damaged over a 

 considerable area, and holes were blown in the sides 

 enclosing the hangar deck. Huge wrinkles disfigured 

 her starboard side. Her interior showed extensive 

 damage also. Her port quarter, being nearest to the 

 Zeropoint, took the worst beating ; much of the wreck- 

 age here was unrecognizable. 



The submarine SKATE, over 300 feet long and of 

 modern heavy construction, was located within one- 

 half mile of the projected Zeropoint. She was on the 

 surface, and as a result lost nearly all her superstruc- 

 ture. The conning tower f airwater and the bridge were 

 badly damaged; the same was true of the weather 

 deck along most of her length. The periscope and radar 

 shears were bent to starboard. Aft of the conning tower 

 most of the decking, the majority of the free-fiooding 

 superstructure, and many pipes and fittings were bent, 

 smashed, or even blown over the side. The bridge struc- 

 ture was folded together upon itself in front of the
