of instrumentation and support equipment the programs will make greater 

 progress. 



This year will be the first year of substantial ocean engineering test- 

 ing, with particular emphasis on SEALAB HI. The "Elk River" (IX-501) 

 will be the MITS support vessel. Operations at 850- to 1,000-ft depths 

 are relatively certain in the near future. The Man- In- The -Sea Program 

 is a continuing effort, and one in which final capability will be dictated by 

 the physiological and psychological limits of man himself. 



The LOSS program will utilize new range installations such as the 

 complete submarine hull and other submarine parts in the early 1970's. 



Initially, the tests of the DSRV will be of the basic vehicles, but 

 once the DSRV becomes operational it will be integrated with other ele- 

 ments in the rescue system. To evaluate whether the vehicle can mate 

 in unfavorable conditions, tests will be conducted first with the new 

 simulated hardware and finally with actual submarines configured as 

 "mother" submarines and simulating distressed conditions. The first 

 phase of the DSRV 1 technical evaluation tests is scheduled to begin at 

 SCI in October, 1969, and last about 18 months. Approximately 6 months 

 after the beginning of the DSRV 1 tests, the phase 1 tests for the DSRV 2 

 will start. About the time tests on the last of the six presently scheduled 

 rescue vehicles and associated support elements are completed, the 

 search vehicle (DSSV) testing is scheduled to begin. 



By the mid-1970's elements of the Deep Ocean Technology 

 (DOT) Project such as the Remote Unmanned Work Systems (RUWS) 

 * and II will be ready for environmental testing at the Ocean 

 Engineering Range. 



Additionally sites are available at other U. S. Navy underwater ranges. 

 The primary function of each of the following ranges is to measure accu- 

 rately the performance of ASW systems: the Atlantic Undersea Test and 

 Evaluation Center (AUTEC) in the Bahamas, the BARSTAR range in the 

 Hawaiian Islands, and the Naval Torpedo Station (NTS) Keyport ranges in 

 the northwest. Each one has an Instrumented sea test area that comple- 

 ments the Ocean Engineering Range by offering different environmental 

 conditions and access to many widespread Navy, industrial, and educa- 

 tional centers.
