BOMBS AT BIKINI 



at a principal naval base will be required. 



Ships more than three-fourths of a mile 

 away may suffer damage, but the damage 

 will be relatively light in typical cases. 



Among the most badly damaged ships, 

 damage to superstructures was very se- 

 vere; hulls escaped relatively lightly. 

 Damage extends to nearly all kinds of me- 

 chanical and electrical equipment. 



DAMAGE TO SPECIAL TEST 

 EQUIPMENT 



Ships' decks, the only platforms in the neighbor- 

 hood of the Zeropoint, had been generously covered 

 with special test equipment of nearly every imaginable 

 kind. Colonel J. D. Frederick's DSM Army Cround 

 Group had exposed equipment lent by all principal 

 branches of the Army, including the Air Forces, Engi- 

 neer Corps, Signal Corps, Ordnance Department, 

 Chemical Corps, and Quartermaster Corps. Much 

 Navy equipment was exposed also, principally by the 

 DSM Ordnance Group under Captain E. B. Mott, the 

 DSM Aeronautics Group under Captain T. C. Lonn- 

 quest, the DSM Electronics Group under Captain C. L. 

 Engelman, and the relatively small DSM Supplies and 

 Accounts Group. So extensive was the equipment that 

 seven volumes of several hundred pages each were re- 

 quired to summarize the results obtained.
