A monitor from the Ra- 

 dioactivity Group uses a 

 Geiger counter to meas- 

 ure the radioactivity on 

 the SKATE. This subma- 

 rine, of modern heavy 

 construction, v^as located 

 v/ithin 1/2 mile of the Test 

 A Zeropoint. Being fully 

 surfaced, she took ter- 

 rific punishment. Most of 

 her superstructure was 

 stripped off, exposing a 

 large area of her pres- 

 sure hull. 



General view of damage produced on the submarine SKATE in Test A. 

 Her conning tower fairwater was badly smashed, and her bridge also. 

 Periscope and radar shears were bent. Inside her pressure hull, how- 

 ever, damage was not severe; within three days she made a successful 

 surface run under her own power.
