PRESSURE HULL: Bi-sphere shape, each sphere is 0.895 in. thick, 7-ft OD and made of 18% nickel, KSI grade, maraging steel. Spheres are welded 



together and connection between the two is a 20-in.-diam, opening. Forward sphere contains three thru-hull penetrations: two are electrical 



penetrations and one is the viewport. After sphere contains three reinforced welded inserts for the three access hatches. 



BALLAST/BUOYANCY: Main ballast consists of four tanks mounted two on each side to provide a reserve buoyancy of 12%. A seawater variable 



ballast system of two spherical tanks, 37-in.-dianri,, 200-KSI grade maraging steel, one on each side, provides 1,828 lb of ballast. A steel shot ballast 



system (three separate tanks) supplies 1 ,700 lb of ballast. Syntactic foam (36,000 lb at 36 Dcf ave. density) provides additional positive buoyancy. 



PROPULSION/CONTROL: Forward and reverse thrust is from two, reversible, stern-mounted, 7.5 hp, AC, motor driven propellers. Vertical thrust 



is from two fore- and aft-mounted, 7.5-hp, AC motors and ducted propellers. Lateral thrust is from fore- and aft-mounted water jets powered by two 



7.5-hp, AC motors. A rudder and stern planes provide additional underway steering control. 



TRIM: A 30° up or down bow angle can be produced by transferring 1 ,440 lb of oil and mercury between two fore- and aft-mounted, 18-in.-diam., 



spherical, steel tanks. A 1 0° port or starboard list can be attained by transfer of 828 lb of mercury between two 15-in.-diam. tanks. Both trim and 



list systems are pressure compensated. 



POWER SOURCE: Main power is derived from two 115-VDC, pressure-compensated, lead-acid batteries mounted below and between the 



bi-spheres. Two 23-VDC, silver zinc batteries are carried in the pressure hull to provide 3.6 kWh of emergency power. Each main battery consists of 



four 30-VDC, series-connected batteries composed of 1 6 Exide RSC lead-acid cells. 



LIFE SUPPORT: Four 0.37-ft3-capacity tanks (2,250 psi) supply O2 for normal usage. CO2 is removed by blowing the air through LiOH/charcoal 



cannisters. O-, level is automatically monitored and regulated. Emergency breathing is by four full-face masks connected to an oxygen- demand 



system for survival periods of 1 2 man-hr. Temperature and humidity are automatically regulated. 



VIEWING: Two acrylic plastic viewports are provided. One is located on the axis of the forward sphere and is a few degrees below the horizontal, it 



is 3 in. thick, 9-in. OD, 3-in. ID. The second is in the aft sphere and looks directly downward, it is 5 in. thick, 1 5-in. OD, 5-in. ID. The aft viewport is 



equipped with an optical remote viewing system of 180 objective in the vertical and 360 in the horizontal. 



OPERATING/SCIENTIFIC EQUIPMENT: UQC, gyrocompass, CTFM sonar, altitude/depth sonar, vehicle control computer, four TV cameras, 



70-mm still camera/with strobe light, sediment corer, sediment vane shear device. 



MANIPULATORS: Two manipulators mounted forward and capable of seven degrees of freedom. 



SAFETY FEATURES: Emergency breathing apparatus. Emergency power within the pressure hull. Positive buoyancy can be obtained by 



jettisoning: shot ballast (1,700 lb), list mercury (800 lb), trim mercury (1,250 lb), main batteries (3,500 lb) and manipulators (170 lb). 



SURFACE SUPPORT: Supported by a 100-ft (LOA), 40-ft beam, 395-ton, split stern ship using an elevator ramp for launch/retrieval. An operations 



manager coordinates sub and ship operations at sea. Two pilots and 18 additional personnel onboard ship maintain and support at-sea operations. 



Vehicle is air and semi-trailer transportable.
