TARGET ARRAY PREPARATIONS. At Pearl Har- 

 bor experiments were conducted to perfect the 

 controlled submerging of crewless submarines. On 

 the submarine rescue vessel "Widgeon" men watch 

 the submarine "Apogon" as she is test-submerged. 

 OPPOSITE. Men of the Navy salvage ship "Re- 

 claimer" hoist a 14-ton anchor over the side. An- 

 chors of this type were used to hold submarines 

 in place during the second atomic bomb test. 

 Larger ships were secured more strongly; a 20,000 

 pound mooring block was placed on the lagoon 

 floor, and held in place by three anchors of the 

 type shown above. This hefty mooring system was 

 connected to a mooring buoy on the surface and 

 thence to the target vessel in question. Central 

 target ships were moored fore and aft.
