7. Underwater construction 



We are having to build a broad base of new technology to pro- 

 vide these expanded capabilities. The technology base has been 

 divided, for administrative purposes, into fi^nctional areas such 

 as energy sources, materials and structural analysis, environmental 

 support, sea floor engineering and so on. 



The efforts involved in thi<:, Engineering program are well known 

 to most of you here. The underwater search and location program 

 involves a 20,000 foot vehicle in addition to unmanned devices. 



Work on a fuel cell power plant is underway. 



In Submarine Escape and Rescue we are putting our chips on a 

 Deep Submergence Rescue Vehicle-DSRV for short. The contractor 

 will deliver the first of these vehicles for testing late this 

 summer. It will be transportable by air, surface vessel or sub- 

 marine. These systems will permit us to respond quickly to the 

 need to rescue personnel from any submarine bottomed above its 

 crush depth. 



Another remarkable vehicle in this program is the recently 

 launched KR-1. This is a small nuclear powered submersible capable 

 of sustained operations; we expect it to be a very valuable plat- 

 form for ■undersea research. It will not go as deep as the DSSV I 

 mentioned, but it will stay down till the crew tires out. 



Our Salvage and Recovery efforts are aimed at developing the 

 ability to raise objects the size of a submarine hull from depths 

 down to 850 feet. 



The Salvage program, in turn, is dependent on our Man-in-The- 

 Sea program which includes the development of improved deep diving 

 techniques. The Ravy has pioneered in diving and developed the 

 technique of saturation diving. As you know we have had recent 

 difficulties. However we cannot give up on this. It is too im- 

 portant both to the Wavy and to the private sector of our country. 

 We intend to p"ursue Man-in-The-Sea to completion in order to give 

 our operating forces the hardware and techniques they require for 

 accomplishing useful work by divers to depths of 1,000 feet or 

 more. Biomedical knowledge is critical here, and we are working 

 hard at it. 



Underwater construction also is dependent to a great extent on 

 the work being done in the diving and vehicle areas, and these pro- 

 grams are all being pushed along together.
