BOMBS AT BIKINI 



Amen and Erik were sprayed once. These precautions 

 proved effective. 



Preparing moorings was a large job. The mooring 

 positions had been specified several weeks in advance, 

 in Washington, D. C. ; plans called for mooring bows 

 and sterns of the central target ships to prevent exces- 

 sive shifting: with tide and wind.*

FORCE ORGANIZATION 



Technical and scientific preparations were nearly 

 complete as A-Day approached. But the success of that 

 day was to depend fully as much on the Force Organi- 

 zation as on the Staff and Technical Organization. 



The Force Organization was responsible for oper- 

 ations. After policy questions had been decided by 

 the staff organization and after the technical require- 

 ments had been decided by the technical men, it be- 

 came the responsibility of the Force Organization to 

 execute the necessary action in the field. 



The Force Organization which had been adopted 

 by Admiral Blandy was designed especially to meet 

 the unusual requirements of the Operation. Eight sep- 

 arate Task Groups were created. 



*A typical mooring consisted of a buoy, a riser chain, a clump, 

 three 10-ton anchors, and three anchor chains. The clump was a 

 10-ton concrete block resting on the bottom of the lagoon. It was 

 attached to the anchors by means of 500-ft. chains. The riser chain 

 coymecting the buoy and the clump was made as short as feasible, 

 to limit the swing of the attached target vessel.
