SUPPORT REQUIREMENTS 



Transportation 



As it is one of the larger deep submersibles, 

 DEEP QUEST is normally considered only sea 

 transportable. However, with the sail and 

 stern planes removed, DEEP QUEST could be 

 air (C-141) and land (tractor, trailer, rail) 

 transportable. At its home port, San Diego, a 

 marine railway is available to transport it in 

 and out of its shop. 



Support Platform 



The Motor Vessel TRANSQUEST (see Table 

 12.2 for specifications) was specifically de- 

 signed to support DEEP QUEST in extended 

 open-sea operations, but it is somewhat lim- 

 ited by its size (108 ft) and speed (6.2 knots 

 max.).

Tracking and Navigation 



Tracking of DEEP QUEST was outlined 

 under Acoustics above and is utilized to vector 

 DEEP QUEST to desired locations as well as 

 to track her movements. Three systems are 

 available aboard DEEP QUEST for naviga- 

 tion independent of the surface (Fig. 2.8). The 

 first system consists of a gyrocompass (provid- 

 ing heading azimuth which is further cor- 

 rected to true heading by a vertical reference 

 gyro and the navigation computer), a Doppler 

 sonar log (provides vehicle speed relative to 

 the bottom), and an analog computer which 

 processes the direction and speed information 

 and plots the vehicle's course on an x-y plot- 

 ter, as well as presenting the information to a
