 Two independent 28-VDC, silver-zinc batter- 

 ies within the pressure hull provide 3.6 kWh 

 of emergency power. 



Maneuverability 



The axial, vertical, and lateral propulsive 

 units, as described in Figure 2.5, in conjunc- 

 tion with stern planes and a rudder, provide 

 five degrees of freedom (pitch, roll, heave, 

 yaw, surge) and a dynamic maneuvering ca- 

 pability through the speed range of to 3.5 

 knots. Static roll and pitch rotational mo- 

 ments are applied by weight transfer in the 

 trim and list systems. An automatic pilot 

 (course, speed and pitch angle) and an auto- 



matic depth control are additional control 

 adjuncts. 



External Attachments 



DEEP QUEST offers several areas for at- 

 tachment of instruments, and a jettisonable, 

 steel framework or "brow" may be attached 

 on the bow to carry a variety of instruments 

 including a 700-pound coring device or a 1,- 

 500-pound reel of line. Abaft the pressure 

 hull is an enclosed area within the fairing of 

 approximately 385 cubic feet; this area may 

 be used to accommodate instruments or tools 

 of widely varying dimensions and weights. In 

 the event that these areas are not desirable 

 or usable, it is possible to attach instruments 

 to the top of the vehicle by bolting down 

 "Unistrut" configurations as desired (Fig. 

 2.6). Within the after pressure sphere two 19-
