COLLAPSE DEPTH: 2,400 ft 



LAUNCH DATE: 1966 



HATCH DIAMETER: 20 in. 



LIFE SUPPORT (MAX): 48 man-hr 



TOTAL POWER: 14.8 kWh 



SPEED (KNOTS): CRUISE 1/10 hr 



MAX 3/1.5 hr 



CREW: PILOTS 1

PAYLOAD: 250 lb 



PRESSURE HULL: Spherical shape, 5-ft ID, 5/8 in. thick, of HY-80 steel. 



BALLAST/BUOYANCY: Main ballast tank of 500-lb capacity is blown bv four tanks of compressed air at 2,250 psi. Auxiliary seawater ballast tank 



of 1 30-lb capacity is used to obtain buoyancy adjustnnents when submerged. Two blocks of syntactic foam (30-pcf density) are carried fore and aft 



to provide additional positive buoyancy. 



PROPULSION/CONTROL: Main propulsion is provided by two propellers mounted aft on stabilizing fins and driven by a 2-hp, DC motor at 900 



rpm which is reversible. Immediately behind the hatch is a vertical thruster of similar characteristics as the main propulsion units. Electrically-driven 



rudder controls underway lateral maneuvering. 



TRIM: No systems provided. 



POWER SOURCE: Main power is derived from externally-mounted, pressure-compensated lead-acid batteries (Exide 3-FN-17) providing 180 



amp-hr at 1 1 5 VDC. 



LIFE SUPPORT: Gaseous O2 is carried within the hull. CO2 is removed by soda sorb. 



VIEWING: Six viewports 5-in. ID, 9-in. OD and 0.625 in. thick. A smaller viewport (2-in. ID) is located in the hatch cover. 



OPERATING/SCIENTIFIC EQUIPMENT: UQC, CB radio, still camera, TV, pinger, Magnesyn compass, altitude/depth echo sounder, depth gage. 



MANIPULATORS: One. 



SAFETY FEATURES: Droppable skid (300 lb). Emergency battery pack in pressure hull. Scuba regulator in pressure hull provides emergency 



breathing by drawing off the deballasting air supply. Hull can be flooded for emergency egress. 



SURFACE SUPPORT: SOO. 



OWNER: Electric Boat Div., General Dynamics Corp., Groton, Conn, 



BUILDER: Same as above.
