TYPICAL HARBOR AN- 

 CHORAGE. This diagram, 

 depicting an area identical 

 to that of the target array 

 shown on the preceding 

 page, shows a typical harbor 

 anchorage of naval vessels, 

 and, by contrast, emphasizes 

 the high degree of concen- 

 tration of the target ships 

 used at Bikini. In the harbor 

 anchorage only four to eight 

 ships would normally appear 

 in an area of one square 

 mile, instead of 20, as at Bi- 

 kini. When the test plans 

 were first announced many 

 persons erroneously assumed 

 that the target array se- 

 lected would be a tactical 

 one. Actually, the array was 

 entirely artificial, and of no 

 tactical validity. 



CARRIER FORCE AT SEA. 



Shown here for further com- 

 parison is a diagram of a 

 carrier task force in cruising 

 formation. Only one capital 

 ship is included in an area of 

 one square mile. In studying 

 the target array opposite, 

 note that the various types 

 of vessels were arranged in 

 curved lines radiating from 

 the bullseye ship "Nevada." 

 Each line was composed of 

 ships of a single type, such 

 as APA's, destroyers, LCI's, 

 LST's, or LCT's. The individ- 

 ual ships served as excellent 

 gages for determining how 

 damage to a given type of 

 ship varied with distance 

 from the bomb burst. For 

 Test Baker the arrangement 

 of ships was generally similar 

 to that used for Test Able.
