Rescue of Personnel From Submarines 



A new system for rescuing personnel from sunken combatant sub- 

 marines is currently under development to replace the McCann bell 

 system developed over thirty-five years ago. The central element of 

 this new rescue system is a 30-ton, 50-foot rescue vehicle capable of re- 

 moving two dozen people per trip from a disabled submarine. Figure 

 18 shows how people will transfer from the disabled submarine to the 

 rescue vehicle. The first prototype rescue submarine is scheduled for 

 delivery in Jime 1968 and construction of a second submarine begins 

 the next year. The vehicle can be transported in the C-141 aircraft, 

 thus enabling the rescue system to respond quickly to a submarine dis- 

 aster almost anywhere. 



Salvage 



The Navy program includes development of techniques to raise 

 sunken ships or large elements from deep water. Studies being con- 

 ducted now emphasize recovery from continental margin depths — 

 1,000 feet or less. For salvage in deeper water, economical solutions 

 are being sought for techniques for generating large but controllable 

 lift and buoyancy forces; means of eliminating or minimizing the 

 adverse effects of sea-surface motion; extension of man-in-the-sea to
