PRESSURE HULL; Cylindrical shape, constructed of aluminum alloy 7079-T6 into 1 1 forged cylinders and 2 hemispherical endcaps all of which are 



bolted together. Cylinder length 43 ft 4 in., OD 8. 1 ft, thickness 6.5 in. Metal to metal contact between sections. All penetrations are in hemi-heads. 



Hull thickness at viewports is 7 in. 



BALLAST/BUOYANCY Pressure hull provides primary positive buoyancy, seawater ballast tanks provide additional positive buoyancy. A 



maximum of 4,700 lb of iron shot ballast provides primary negative buoyancy in two tanks amidships port and starboard. Another source of primary 



negative buoyancy is from a 4,400-lb lead bar in the keel. At 4,000-ft depth the ballast tanks can be blown free of water to obtain 2,000 lb of 



positive buoyancy by displacing approximately 30 ft-* of water. 



PROPULSION/CONTROL: Horizontal propulsion is from two reversible, 5-hp, DC motors mounted port and starboard on the stern. Vertical 



propulsion is from a 5-hp, DC motor mounted topside amidships. Stern-mounted dive planes provide additional underway control. Horizontal 



maneuvering is through an electrically driven rudder or by using horizontal thrusters in opposition or other combinations. 



TRIM; Trim system is internal and consists of 300-lb-capacity tanks from which water can be pumped fore and aft. Lead ballast in the form of 50-lb 



blocks can be manually shifted to maintain desired trim to +30 bow angle. 



POWER SOURCE; Four 115-V, 400-amp-hr, silver-zinc batteries are in the pressure hull and provide nearly 20,000 Wh. The following forms of 



power are available; 115 VDC direct from batteries (118-140 V long-term potential), 230 VDC direct (236-280 V long-term potential), 28 VDC 



regulated (+10% voltage, +5% frequency) AC, 2.5-W, continuous, 115-V, 60-cycle super-regulated (+1% voltage, +0.03% frequency, 1 kw 



continuous). 



LIFE SUPPORT; On is supplied from two steel flasks of 127-ft3 capacity each. CO2 removed from cabin air by blowing through a scrubber 



containing 12 lb LiOH. 



VIEWING; Four viewports located in the bow provide a 160° (total) horizontal field of view through three of the ports and a vertical field of view 



from 25° above the horizontal to 80° below through two ports. Each viewport is 7% in. thick with a 4-tn. ID and a 19-in. OD. 



OPE RATING/SCI EIMTIFIC EQUIPMENT; Two up/down Fathometers, CTFM sonar, side scanning sonar, closed circuit television w/light mounted 



on pan and tilt mechanism, tape recorder, exterior-mounted depth gage, gyrocompass and UQC. 



MANIPULATORS; Two, each with six degrees of freedom. 



SAFETY FEATURES; Shot (4,700 lb) and lead keel bar (4,400 lb) are electromagnetically held and may be dropped automatically or manually in 



the event of a power failure. Oxygen Breathing Apparatus (OBA) is supplied which provides 2 hr of emergency breathing/occupant. Ballast tanks can 



be blown at depths to 4,000 ft to supply some 2,000 lb of positive buoyancy. 



SURFACE/SHORE SUPPORT; ALUMINAUT is towed by a 1 35-f t support ship to dive site or anchorage. Ship's crew and support divers total 10, 



submersible's crew; pilot, co-pilot, 3 engineers. An operations officer coordinates the field effort and five additional personnel are ashore. The total 



required to operate the system is 21. Land facilities include a marine railway and barn to lift and shelter the vehicle for maintenance and repair,
