CONCLUSIONS 



1. An explosive anchor for salvage operations has been demonstrated 

 to be workable and feasible. 



2. A design has been attained that meets the particular urgent 

 need for anchoring capability in coral seafloors. 



3. Minor improvements in the existing design are needed to 

 enhance its functioning and reliability for use in emergency situations. 



4. Major redesigns of the launch vehicle and ordnance system are 

 needed to achieve broader capabilities and make the explosive salvage 

 anchor acceptable as standard salvage gear. 



RECOMMENDATIONS 



1. Improve the existing hardware by designing a unit package 



for attachment and protection of the attitude indicator and S/A device, 

 by devising a method to relieve premature pressure on the shear pins, 

 and by modifying the mechanical cable release. 



2. Redesign the launch vehicle to reduce it in size and weight, 

 to improve its configuration for fabricating, stowing, handling, and 

 placing, and to improve its structural integrity. 



3. Redesign the ordnance system to reduce the size of the safe 

 and arm device and make it more reliable and less expensive and to 

 eliminate the use of mild detonating fuzes in the firing train. 



ACKNOWLEDGMENTS 



The Naval Weapons Laboratory at Dahlgren, Virginia provided 

 valuable guidance and consultation on the ordnance safety aspects of 

 the design, testing, and appraisal. In particular, the exceptional 

 cooperation and significant contributions of Mr. Stuart McElroy and 

 Mr. Bud Troxall of NWL are recognized. 



Outstanding support and cooperation was received from various 

 ships and activities throughout the test program. Recognition of and 

 appreciation to these organizations are expressed in the approximate 

 chronological order of their participation. Some were involved in 

 more than one phase of the testing.
