STAR III 



LENGTH: 24.5 ft 



BEAM: 6.75 <t 



HEIGHT: 8 ft 



DRAFT: 6.5 ft 



WEIGHT (DRY): 10.5 tons 



OPERATING DEPTH: 2,000 ft 



COLLAPSE DEPTH; 4,000 ft 



LAUNCH DATE: 1966 



HATCH DIAMETER; 20 in. 



LIFE SUPPORT (MAX): 120 nnan-hr 



TOTAL POWER; 30 kWh 



SPEED (KNOTS); CRUISE 1/12 hr 



MAX 4/1.5 hr 



CREW: PILOTS 1 



OBSERVERS 1 



PAYLOAD: 1,000 lb 



PRESSURE HULL: Spherical shape, 5.5-ft ID, 0.5 in. thick and made of HY-100 steel. 



BALLAST/BUOYANCY: NA. 



PROPULSION/CONTROL: Main propulsion is provided by a stern-mounted, reversible, 7.5-hp propeller. One vertical and one horizontal thruster, 



each powered by a 2-hp motor, assist in maneuvering. An electrically-actuated rudder assists in underway maneuvering. 



TRIM: Bow angles of +30 can be obtained by transferring mercury between fore and aft tanks. 



POWER SOURCE: Sixty, external, pressure-compensated, lead-acid battery cells provide 29 kWh of 120-VDC power at a 10-hr discharge rate. This 



can be converted to 1 1 5 VAC, 60 Hz. 



LIFE SUPPORT: A pressure regulator automatically bleeds O2 from a 72-ft^-capacity tank into the hull. CO2 is removed by soda sorb. A reserve 



O2 tank is carried that is manually operated as desired. Monitors for O2, CO2 and cabin pressure. Emergency breathing is from two scuba regulators 



drawing off the high pressure air supply. 



VIEWING: There are five viewports, each is 2 in. thick with a 5-in. ID and a 9-in OD. Three of the ports look forward and are depressed 33° from 



the horizontal. One of these is on the vertical centerline. The remaining two viewports are raised approximately 10 above the horizontal and are 



located 90 to the right and left of the centerline. Each viewport has a field of view of 69 in water. 



OPERATING/SCIENTIFIC EQUIPMENT: UQC, CB radio, pinger, Magnesyn compass, altitude/depth echo sounder, depth gage, two TV cameras, 



still camera. 



MANIPULATORS: One with six degrees of freedom. 



SAFETY FEATURES: Lead weight (250 lb) drops automatically if high pressure air supply drops below 185 psi above ambient seawater pressure 



Manipulator jettisonable. Hull can be flooded for emergency egress. 



SURFACE SUPPORT: SCO. 



OWNER: Scripps Institute of Oceanography, La Jolla, Calif. 



BUILDER: Electric Boat Dtv., General Dynamics Corp., Groton, Conn.
