OPERATING DEPTH: 2,000 ft 



COLLAPSE DEPTH: NA 



LAUNCH DATE: 1972 



HATCH DIAMETER: NA 



LIFE SUPPORT (MAX): 48 ,Tian-hr 



TOTAL POWER: Tethered 



SPEED (KNOTS): CRUISE NA 



MAX 2 



CREW: PILOTS 1 



OBSERVERS 1 



PAYLOAD: 750 lb 



PRESSURE HULL; Spherical shape, 66 in. OD, 0.5 in. thick and composed of H Y^O steel. 



BALLAST/BUOYANCY: Large weight changes are compensated for before the dive by changing external weights in the fixed ballast compartment 



on a droppable weight platform. Small buoyancy changes during the dive are obtained through a variable ballast tank (200-lb capacity). The tank is 



flooded to fill and pumped dry. 



PROPULSION/CONTROL; Five motors provide propulsion. Three are for horizontal motion and are mounted port, starboard and aft, the aft 



motor is trainable 90° left and right. The remaining two motors are thrusters for horizontal and vertical control- All motors are oil-compensated, 



1 0-hp, 350-lb thrust, and are reversible with two speeds forward and aft. 



TRIM: No systems provided. 



POWER SOURCE: An umbilical from the surface provides 50 kW of power from a diesel generator providing 440-VAC regulated power. 



Communications, TV transmission and voltage sensing also passes through this wire. The umbilical is 1,000 ft long, 1.4-in. diam. and has a breaking 



strength of 10,000 lb, it can be cut by the vehicle if the need arises. 



LIFE SUPPORT: Three O2 flasks are carried in the hull. CO2 is removed by Baralyme in a forced-air scrubber. O2 is monitored by a Teledyne 



Analyzer, CO2 is monitored by a Drager Analyzer, a second Drager Analyzer (Multi-gas Detector Mod. 21) measures both CO2 and CO. An altimeter 



measures cabin pressure. Two scuba bottles (compressed air) and regulators provide emergency breathing for approximately 4 man-hr. 



VIEWING: There are 13 viewports total. Four are in the hull, eight in the conning tower and one in the hatch. 



OPERATING/SCIENTIFIC EQUIPMENT: UQC and hard wire communications, scanning sonar, TV, 35-mm still camera 81 strobe, two depth gages, 



directional gyro. 



MANIPULATORS: None. 



SAFETY FEATURES: A 600-lb, droppable weight, emergency breathing, backup communications on batteries, umbilical cutter, running lights, fire 



extinguisher, life jackets, underwater flashlights. 



SURFACE SUPPORT: SOO. 



OWNER: Phillips Petroleum, Bartlesville, Okla. 



BUILDER: Perry Submarine Builders, Riviera Beach, Fla. 



REMARKS: Inactive, has not made an operational dive.
