PRESSURE HULL: Cylindrical shape, composed of a steel cylinder and hemispherical endcaps. Hull diameter is 1.90 m and length is 4.84 m, A 



cylindrical conning tower, called a trunk, is welded to the cylinder. Two hoisting eyes and two keel skates are also welded to the hull. 



BALLAST/BUOYANCY: Two main ballast tanks (38.4-ft^ capacity), welded to the sides of the pressure hull, are flooded to descend to a decks 



awash depth, water is then admitted into a compensating tank until the conning tower is almost submerged, at this point the vehicle is trimmed to a 



down angle and the vehicle is powered to depth. Ascent is effected by powering to the surface where the main tanks are blown. 



PROPULSION/CONTROL: Two side mounted propellers each driven by a 6-hp motor provide propulsion in the lateral and vertical. The motors are 



reversible, two speed and 360 rotatable. 



TRIM: A weight (150 kg) may be hydraulically shifted along a horizontal rail to obtain a trim angle of ±20°. 



POWER SOURCE: Two lead-acid banery packages of 48 cells each within the pressure hull, supply power at 165 amp-hr (5 hr discharge). A 



diesel-electric motor is used for surface power to charge batteries and drive a compressor to fill air tanks. 



LIFE SUPPORT: Three O2 flasks (5 I each) are carried within the hull. CO2 scrubbers (soda lime) are also carried. On the surface it is possible to 



draw fresh air into the hull with a snorkel device and thereby avoid opening the hatch. 



VIEWING: Four viewports in the forward hemisphere 283-mm OD; 155-mm ID and 65 mm thick. Five viewports in conning tower 203-mm ID," 



105-mm OD and 50 mm thick. 



OPERATING/SCIENTIFIC EQUIPMENT: UQC, echo sounder, depth gage, gyrocompass, forward-scanning sonar, radio, radar reflector, surface 



lights. 



MANIPULATORS: One mechanical arm which may be used to 200-ft depth. 



SAFETY FEATURES: Main ballast tank s may be blown at any depth. Droppable lead weight between skegs (100 kg), tf the vehicle descends below 



Its operating depth main ballast tanks are automatically blown. This system will activate automatically unless stopped once every 15 minutes. 



Pressure hull may be flooded for emergency escape using a closed circuit breathing system. Marker buoy and snorkel.
