PRESSURE HULL: Passenger compartment is a stiffened cylinder with hemispherical endcaps. Main hull and battery compartment is 0.5-in. thick, 



SA 212 grade B steel, conning tower and motor room are 3/8-in. SA 212 grade B steel; hatch is Almag 35 steel. Passenger, motor, and battery 



compartments have separate, water-tight integrity. 



BALLAST/BUOYANCY; Buoyancy control tanks, made of 18 gage, 304 stainless steel, are located within the hull and have a total capacity of 260 



lb. A hydropump (4 gpm, 700 psi) can pump from tanks to sea or sea to tanks or bilges to tanks. The pump motor is a G.E,, 120-V, 2-hp at 750 rpm. 



Main ballast tanks straddle the pressure hull. 



PROPULSION CONTROL: Stern-mounted propeller provides main horizontal propulsion and is driven by a 10 hp motor. Two bow and one stern 



thruster of fractional hp are fluid filled, and 36° trainable. Plexiglass bow planes assist in controlling underway vertical motion. 



TRIM: A mechanical control systenn within the pilot's compartment moves lead slugs fore or aft in trim tubes located in the battery compartment. 



POWER SOURCE: Twenty 12 V, 67-amp-hr, 20-hr-rated, lead-acid batteries in separate water-tight compartment with nitrogen atmosphere and 



provisions for purging. Power available to customer: 120 VDC. 100 amp; 12 VDC, 2 amp. Additional 4-amp inverter available. 



LIFE SUPPORT: Three blowers supply air through three 4 lb beds of Baralyme with 36 lb carried in reserve for 52 hr of life support for three men. 



Increasing to three 6-lb beds of LiOH extends life support for three men to 60 hr, Ot supply is 50-ft^ bottles (ea.) at 2,000 psi carried externally. 



Reserve supply of chlorate candles can be made available to provide 50-man-hr support. Three emergency regulators operate off the air system.
