20. ABSTRACT (Continue on reverse side if necessary and identify by 6/och number) 



CEL has developed a new lightweight propellant-actuated embedment anchor with a 

 nominal long-term holding capacity of 10,000 pounds (45 kN). Through the use of stock 

 components, the anchor can be inexpensively fabricated and used. Land tests have 

 demonstrated the structural integrity of the design and verified the predicted ballistic 

 performance. Sea tests were conducted in a coral seafloor at Midway Island. The anchors 

 that were successfully embedded indicated holding capacities on the order of 30,000
