PAYLOAD: 1,100 1b 



PRESSURE HULL: Cylindrical shape of A516 grade 70 steel, 46-in. diam., 105 in. long. 



BALLAST/BUOYANCY: Main ballast is from fore/aft mounted fiberglass tanks which are vented or blown dry to provide negative or positive 



buoyancy, respectively. A low pressure surface buoyancy system is provided to obtain reserve buoyancy. 



PROPULSION/CONTROL: Lateral movement is provided through a stern-mounted, reversible propeller capable of training 90° port or starboard 



and powered by a pressure-compensated 5-hp motor. Vertical underway control is by port/starboard bow planes mounted forward and above the 



bow viewing dome. 



TRIM: Up/down bow angles can be controlled by bow planes. Two fore and aft fiberglass tanks, subdivided at centerline, can be filled with ambient 



seawater or blown dry collectively or individually to provide both ballast and trim. 



POWER SOURCE: Lead-acid batteries contained in pressure-resistant cylinders (20-in. diam., 96 in. long) of the same material as the pressure hull 



are connected to provide a nominal voltage of 1 20 V at 225 amp-hr. A 15-V nickel-cadmium battery inside the pressure hull provides emergency 



power. 



LIFE SUPPORT: O2 is carried in two 70-SCF (nominal) tanks. COj is removed by LiOH cannisters. 



VIEWING: One 39-in.-diam., acrylic plastic (grade G plexiglass) dome in forward end of pressure hull. Smaller viewports are elsewhere on conning 



tower and hatch. 



OPERATING/SCIENTIFIC EQUIPMENT: UQC, scanning sonar, depth gage, compass. 



MANIPULATORS One with six degrees of freedom. 



SAFETY FEATURES: Jettisonable propulsion unit and manipulator claw. Emergency power (15-V Ni-Cad battery) in pressure hull. Self-contained 



O2 rebreathers. Manually droppable weight. Life vests, dry chemical fire extinguishers and flashlights. 



SURFACE/SHORE SUPPORT: SOO 



OWNER: International Hydrodynamics, Inc., Vancouver, B.C. 



BUILDER: Same as above. 



REMARKS: Operational.
