PRESSURE HULL: Cylindrical shape with hemispherical endcaps. Composed of mild steel (A-212) 0.5 in. thick and 36-in. OD on bodv and 24-in. 



CD on conning tower. Cylinder is approximately 8.3 ft long, conning tower is approximately 2.2 ft high. 



BALLAST/BUOYANCY: At launch vehicle is positively buoyant and made negative by flooding a small volume tank located on conning tower 



fairing, A 12-ft-' capacity tank provides additional freeboard when on the surface. Both tanks are free flooding and open to the sea at their lowest 



point at all times. 



PROPULSION/CONTROL: One stern-mounted, reversible propeller driven by a 2-hp electric motor and capable of rotating 220° in the horizontal 



provides forward, reverse and lateral movement. 



TRIM: No system included. 



POWER SOURCE: Four 205-amp, 6 V, lead-acid, pressure-compensated batteries mounted under the pressure hull provide main propulsion power. 



Alt other power is supplied by two 1 00-amp, 24-V, nickel-cadmium batteries carried within the pressure sphere. 



LIFE SUPPORT: O2 is carried within the pressure hull and CO2 is removed by blowing cabin air through a Baralyme cannister. 



VIEWING: Ten acrylic plastic viewports all 2.5 in. thick. Two viewports are 12-in. OD, five are 10.5-in. ID and three are 8- in. ID.

12 flood lights of 250-W capacity each contained within four (three bulbs/dome) pressure-resistant pyrex domes. Vehicle was designed primarily for 



photography. 



MANIPULATORS: One mounted forward of pressure sphere capable of two degrees of freedom and 8-lb lift. 



SAFETY FEATURES: Hand-operated, hydraulically-releasable 140-lb weight. Mechanically-droppable battery pod (400 lb). Pressure hull is 



floodable to allow egress in the event of emergency.
