The anchor is quickly assembled and can be easUy 

 handled and deployed from a variety of vessels, 

 including ATF, ARS, ARC, Buoy tender, and Navy 

 warping tug. Anchor cost for shallow-water opera- 

 tions (<600 feet) has been reduced by up to 40% 

 through a new, reusable safe-and-arm device for the 

 system. The cost of the nonrecoverable items per 

 anchor firing in shallow water is now $1,400. In deep 

 water, assuming that the launching system is not 

 recovered, the total cost is $4,500 per anchor firing 

 ($3,100 of which is the launching system). 



The idea that propellant-actuated anchors offer 

 practical alternatives to conventional anchors has 

 been supported by the available tests and operational 

 uses of the anchor. High efficiency, light weight, ease 

 of handling, adaptability, multidirectional load- 

 resisting capability, and low cost are a few of the 

 anchor's qualities that support this contention. 



Practical methods for installing the 20K anchor, 

 for recovering the anchor, and for recovering anchor 

 components in deep water have been conceived. Use 

 of this anchor will expand once these procedures, 

 which eliminate total dependence upon single-line 

 lowering and deep-water launching system expenda- 

 bility, are tried and perfected. 



The testing accomplished so far has been limited 

 and designed principally to determine whether the 

 anchor works. There has not been enough testing to
