CREW: PILOTS 1 



OBSERVERS . . . . 2 



PAYLOAD: 500 lb 



PRESSURE HULL: Cylindrical shape of SA-537 grade A nornnalized steel 9/16 in. thick, 54.in. ID, 218-in. length. 



BALLAST /BUOYANCY: Main buovancy (1,100 lb) is from a soft reservoir tank connected to a smaller hard tank, both are blown by compressed 



air. Two internal, fore/aft tanks control fine buoyancy or trim (±400 lb). 



PROPULSION/CONTROL: Main propulsion is through a variable-speed reversible lOhp, DC electric motor mounted in a water-tight container in 



the stern which drives a stern propeller. One single-speed reversible bow thruster (0.75-hp) and two 0.5-hp vertical thrusters provide low speed 



maneuvering. Hydraulically activated bow planes and rudder control attitude underway. An automatic pilot controls rudder angle. 



TRIM; Two, internally-mounted, fore and aft tanks can be differentially filled with seawater to attain up/down angles on the bow. 



POWER SOURCE: Twin battery pods, 18-in. diam. of SA53 grade B steel, contain 6-V, lead-acid heavy duty baneries providing 120 VDC main 



power l41.6kWhat20hr) and 24. VDC auxiliary power (8.3 kWh at 20 hr). 



LIFE SUPPORT: Gaseous Oj (four tanks) is carried external to the pressure hull. 240-ft^ total capacity. CO2 is removed by LiOH (6.4 lb). 



VIEWING: Twenty-one viewports; nine in the forward pressure hull, nine in the conning tower and three aft. All are 6.25-in. ID, 1.5 in. thick, 8-in. 



OD. 



OPERATING/SCIENTIFIC EQUIPMENT: UQC, CB radio, Magnesyn compass, Doppler navigation sonar, scanning sonar, up/down recording echo 



sounder. Transponder and pinger, three TV's with three video recorders and five monitors.

SAFETY FEATURES: Ballast (1,150 lb) can be blown at maximum operating depth. Mechanically droppable 840 lb weight. Emergency breathing 



devices for each passenger. Flashing light. 



SURFACE SUPPORT; Presently supported by the M/V WILLIAM DAMPIER.an off-shore oil supply boat 170 ft long, 39-ft beam, 9 ft draft which 



cruises at 12 knots and has a range of 6,500 n.m. A constant-tension, 50,000-lb-capability, stern A Frame handling system is used for 



launch/retrieval. The support ship can berth 22 people, 2 of these accommodations are for customer personnel.
