COLLAPSE DEPTH: 4,130 ft 



LAUNCH DATE: 1969 



HATCH DIAMETER: 15.75 in. 



LIFE SUPPORT (MAX): 144 man-hr 



TOTAL POWER: 26.5 kWh 



SPEED (KNOTS): CRUISE 1/8 hr 



MAX 3/4 hr 



CREW: PILOTS 1

PAYLOAD: 450 lb 



PRESSURE HULL: Cylindrical shape 5ft OD with hemispherical endcaps. Hull thickness 0.75 in.; overall hull length 10 ft. Hull n-iaterial HY-80 



steel. Penetrations include three viewports, one hatch, seven mechanical and three electrical. 



BALLAST /BUOYANCY: Main ballast system for surface buoyancy consists of flooded soft tanks blown dry with high pressure air. Tanks are an 



integral part of the exostructure and fairing. Variable ballast system consists of four hard tanks and collapsible bladders. Oil is pumped from hard 



tanks to bladders to increase displacement or reversed to decrease displacement. Permanently installed syntactic foam is used to obtain submerged 



neutral buoyancy. 



PROPULSION/CONTROL: Two main propellers in the stern {5-hp ea.), reversible, servo-valve controlled, continuously variable. Two vertical 



thrusters port and starboard, two horizontal thrusters fore and aft. All thrusters are powered by hydraulic motors driven off of the main hydraulic 



plant (two plants at 1 0-hp ea.). Each electric motor is pressure-compensated, 1 20-VDC, 7.5-hp. 



TRIM: Hydraulic-activated drive moves batteries fore or aft allowing pitch angles of up to ±25 . 



POWER SOURCE: Lead-acid batteries; one 120-V, 1 50-amp-hr, two 28-V, 150-amp-hr, located externally and pressure-compensated. Selectively 



droppable. 



LIFE SUPPORT: Gaseous O2; two flasks of 840 in. 3 each at 2,250 psi. Monitors for CO2, Ot, cabin pressure, temperature and humidity. 



Emergency (three 1-hr) breathers. LiOH to remove CO2. 



VIEWING; Two, 4.5-in. ID, of plastic looking 19° downward and slightly to port and starboard giving overlapping fields of view. One, 2-in. ID, 



looking forward on centerline for still camera. 



OPERATING/SCIENTIFIC EQUIPMENT: Sperry MK27 & repeater, FM radio, UQC, TV camera, alt/depth sonar, gyrocompass, pressure, depth, 



rate and acceleration system, extendable light booms with up to 2,500 W of lights, xenon flasher, voice recorder, velocity sensor, temperature probe, 



ambient light sensor, sound velocity sensor, subbottom profiler, side-looking sonar, still and cine cameras and sediment corers. Data logger for any 



digital signal, 8-track. 



MANIPULATORS: One with two degrees of freedom. 



SAFETY FEATURES: Main ballast can be blown at operating depth (500-lb lift). Mechanically jettiscnable high pressure Air Bottles (500 lb). 



Mechanically jenisonable batteries (1,250 lb). Mechanically iettisonable payload brow (500 lb). Emergency breathing, manipulator jettisonable, life 



raft, flares, life jackets. 



SURFACE/SUPPORT: SOD. 



OWNER: Westinghouse Ocean Research and Engineering Center, Annapolis. Md. 



BUILDER: Westinghouse Electric Corp. 



REMARKS: Operationally ready, but has not dived since 1972.
