PRESSURE HULL: Two cvlindrical hulls with hemispherical endcaps; one for atmospheric pressure, one for ambient pressure. Both hulls are made 



of 30-mm-thick, high yield-strength (SMR-type) steel. Atmospheric hull is 16.2 m long, 3.7-m dram., ambient pressure hull is 5 m long, 2.5-m diam. 



Hulls are linked by two spherical lock-out chambers 1 .50-m diam. 



BALLAST/BUOYANCY: Two 1 ,250-l-capacity tanks forward and two 1,650-1 tanks aft supply main ballast. Two tanks of 1,120-1 capacity for trim 



and two tanks of 1 ,500-1 capacity for equalizing submersible displacement when carrying extra equipment. 



PROPULSION/CONTROL; Surface and submerged propulsion is supplied by two Kort nozzles each driven by a hydraulic pump supplying 75 hp at 



330 rpm. The nozzles rotate around a vertical shaft and facilitate normal underway maneuvering. Slow speed maneuvering is attained by fore- and 



aft-mounted vertical and horizontal thrusters. 



TRIM; No systems available. 



POWER SOURCE: Surface power is supplied by a 225-hp diesel engine which accuates a 30-kW, 120-\/DC auxiliary generator for shipboard power 



and a 72-kW, 80-1 20-V generator to recharge batteries. Oil-immersed, pressure-compensated, lead-acid batteries (60 ea.) of Fulmen type-L cells 



supply 10,000 amp-hr. 



LIFE SUPPORT: External to the hull are the following at 250 bars pressure: Fourteen 330-1 air cylinders, fourteen 330-1 O2 cylinders; thirteen 



330-1 He cylinders; one 330-1 He-02 cylinder, A total of 3,500 I of fresh water can be carried in the submarine; 400 I in the underwater house. Food 



is prepared aboard in the main hull and can be transferred to the aft hull. A hookah system can supply air to divers. 



VIEWING: Several viewports located in both passenger and diver hulls. 



OPERATING/SCIENTIFIC EQUIPMENT: UQC, echo sounder, diver lock out capability, TV cameras. 



MANIPULATORS: None. 



SAFETY FEATURES: A releasable steel sphere (2.25-m diam., 20 mm thick) above main hatch can carry entire crew to surface. Crew can depart 



vehicle through lock-out. 



SURFACE/SHORE SUPPORT: Diesel/electric motors provide independent operations to a range of 400 nautical miles.
