PAYLOAD: 10 tons 



PRESSURE HULL: Cylindrical shape of "VOEST" steel quality Aldur 55/68 for cylinder and Aldur 55 for the two hemispherical endcaps. Cylinder 



is 1 .5 in. thick, 1 0.25-ft OD and 59.7 ft long. Endcaps are the same dimensions and equal to radius of the cylinder. Two hatch openings fore and aft. 



BALLAST/BUOYANCY: External to the hull in two rows port and starboard are 12 steel ballast tanks of total volume 842 ft^ which supply 12.5% 



(23.8 tons) positive buoyancy. Three compensating tanks are provided: two (9 ft^ ea.) are in the hull near the center of gravity and one (49 ft^) is 



external to the hull, within the keel. On each side of the hull are four bins which hold 5.75 tons of iron shot electromagnetically released. 



PROPULSION/CONTROL: An electf ic motor of 75 hp (1,500 rpm) drives a stern-mounted propeller. A directional Kort nozzle acts as the vehicles 



rudder. Fore- and aft-mounted diving planes provide underway vertical control and stability. 



TRIM: Two tanks forward and aft of 141 ft-* total capacity are used to trim the vehicle by transferring water fore or aft with an electric pump. 



POWER SOURCE: Five lead-acid batteries within and on the bottom of the pressure hull are distributed as follows: two 110-V capacity, 



2,000-amp-hr for propulsion; one 220-V, 700-3mp-hr for lighting and pumps, one 12-\/, 950-amp-hr for control instruments and emergency lighting, 



and one 6-V, 700-amp-hr for safety ballast control. 



LIFE SUPPORT: Normal dive of a few hours allows for breathing of ambient air inside vehicle at time of dive. For prolonged dives O2 is bled into 



the hull and CO 2 is removed by soda lime which assures a max imum of 2,112 man-hr. 



VIEWING: Twenty viewports each on port and starboard side, and three in forward hemisphere. All viewports provide 90° of viewing and are 3 in. 



thick, 12-in. OD and 6-in. ID. 



OPERATING/SCIENTIFIC EQUIPMENT: TV on sail, compass, pressure depth gages/recorder, down-looking echo sounder. 



MANIPULATORS: None. 



SAFETY FEATURES: Iron shot "fail-safe" droppable. 



SURFACE/SHORE SUPPORT: Size and weight permit only towing to dive site or self-powered transit. '
