An explosive anchor for salvage operations was designed, 

 fabricated, and tested. The primary objective was to alleviate 

 the critical problem of anchoring in coral seafloors but it also 

 was desired to incorporate as broad a range of salvage anchoring 

 capabilities into the new anchor as possible. The prototype is 

 12 feet high, has a 10-foot circular base and weighs about 6 tons. 

 It functioned in coral and developed a holding capacity greater 

 than 150,000 pounds. It also demonstrated potential for service 

 in other seafloors and over a wider range of operational 

 conditions. Further development is proceeding to reduce anchor 

 size and weight and to simplify and make the ordnance system more 

 reliable so that it will meet acceptable operational standards.
