3. The launching system Is satisfactorily sealed against water 

 intrusion. 



4. The ballistic performance is satisfactory and is modeled well 

 by an available computer program. 



Conclusions drawn from the first sea tests were: 



1. The system is workable. 



2. Acceptable holding capacities can be realized in a silt 

 seaf loor. 



3. The system is quickly and easily assembled and handled. 



4. The new fluke design keys quickly and showed no distress 

 either from penetration or pullout. 



FUTURE PLANS 



The anchor will continue to be tested in a variety of seafloors 

 from soft clay to rock and in different water depths to 10,000 feet. 

 As part of the program to generate performance and reliability data, 

 the anchor will also be used where practicable in conjunction with on- 

 going programs. In FY74 final drawings will be prepared for the 

 anchorage system and the propulsion package and safing and arming sys- 

 tem will be subjected to standard safety test programs. It is planned 

 that the anchor be ready for operational use by the end of FY74. Total 

 cost for an entire anchor system is estimated to be $3,500. Anchor 

 deployments in water depths less than 500 feet, where the launch 

 vehicle is retrievable, reduces the cost to about $1,200 per anchor. 



To ease and speed deep sea mooring installation, techniques for 

 auto-mooring the anchor are being evaluated. An auto-mooring system 

 will be designed and fabricated in FY74. 



ACKNOWLEDGEMENTS 



The anchor launching system was designed at the Naval Ordnance 

 Station, Indian Head, Maryland; particular appreciation is given to 

 Al Horst of the Gun System Engineering Branch. The Safe and Arm 

 device was developed at the Naval Underwater Systems Center, Newport, 

 by Dave Ramstead and Dave Pimental. Phil Babineau devised equipment 

 and techniques for simplifying the operation and handling of the anchor.
