BOMBS AT BIKINI 



OPERATIONS PLANNING AND 

 DIRECTION 



Nearly every movement of the Task Force's 242 

 ships and 156 airplanes was made, of course, by direc- 

 tion of the Task Force Commander; but it was the 

 responsibility of Captain C. H. Lyman (Nav,y), Assist- 

 ant Chief of Staff for Operations, to plan and coordi- 

 nate all such movements. Captain W. C. Winn (Navy) 

 assisted in the directing of movement of vessels. He 

 maintained records showing where each ship was, who 

 was in command, what its mission and destination 

 were. When additional ships were required, it w^as his 

 job to obtain them; when certain ships were no longer 

 needed, it was his job to see that they were reassigned. 



Captain Lyman was assisted by Colonel W. D. 

 Graney in the planning and directing of air operations. 

 He was assisted by Captain K. M. Gentry (Navy) in 

 communication matters, including radio, television, 

 and transmission of radio-photographs ; a schedule of 

 348 individual radio frequencies was arranged, of 

 which 163 were assigned to command and administra- 

 tive groups, 107 to instrumentation groups, and 78 to 

 press and radio groups. In the crucial matter of an- 

 alyzing and predicting weather, Captain Lyman was 

 assisted by Colonel B. J. Holzman and Captain A. A. 

 Cumberledge (Navy), outstanding experts in aerology. 



Perhaps the two most important observer groups 

 at Bikini were the Joint Chiefs of Staff's Evaluation
