The deep ocean technology program which is included 

 in the 1968 budget will advance the development of tech- 

 nology leading toward the occupation and exploitation of 

 the deep ocean. Problems to be studied include: 



The development of fuel cell powerplants as a prime 

 mover for deep-diving submersibles. 



The development of reliable, submersible motors, 

 since motors presently in use are all either encapsulated 

 or unreliable. 



The advanced development of tandem propeller propul- 

 sion plants to enhance the maneuverability so vital to 

 deep submersibles in near-bottom operation. 



The development of sea water hydraulic systems to 

 provide for improved reliability of deep ocean machinery 

 and vehicles is also a part of the DOT program. 



As an adjunct to the deep submergence systems pro- 

 ject, the NR-1 will be the first nuclear powered deep 

 submersible. This ship is being designed and constructed 

 under the project managership of DSSP with powerplant 

 development under the management of the Director, Naval 

 Reactors Branch of the Ship Systems Command. The NR-1 

 will operate with a crew of five plus two scientists. In 

 addition to demonstrating the capability of nuclear power 

 in the deep submersible, NR-1 will be fitted with a full 

 suit of sensors for oceanographlc engineering and re- 

 search. 



The worldwide marine geophysical survey program begun 

 in fiscal year 1966 will continue into 1968. These 

 surveys, conducted under Navy contract with two commercial, 

 geophysical companies, will, when completed, have covered 

 16 million square nautical miles or 15 percent of the 

 total ocean. Data are being collected on oceanographlc 

 conditions existing in deepwater masses and at the water/ 

 bottom interface. 



Each of our Navy projects offers several potential 

 applications beyond their direct military objectives: 

 deep submergence search and rescue vehicle technology 

 provides the basis for many uses -- mining, fishing, 

 salvage, mechanical work, research, and data collection; 

 sonar technology in the commercial sector can lead to 

 considerably greater efficiency for future generations 

 of commercial fishermen at a time when the problem of 

 feeding the world population will have increased; man-in- 

 the-sea may provide a key to greater and more rapid
