PAYLOAD: 800 lb (incl. crew) 



PRESSURE HULL: Cylindrical shape with one hemisphere endcap of glass and one of steel. Hull material and one endcap is HY-100 steel 



0.65-in.. thick. Ring stiffened cylindrical pressure hull 6 ft long, 44.5-in, diam. Glass endcap is 1.25.in. -thick Borosilicate weighing 300 lb. 



BALLAST /BUOYANCY: Forty 5-lb steel plates provide slight buoyancy for initial descent and may be dropped individually during the dive to 



attain positive buoyancy. Twenty 3-lb buoyancy blocks provide variable buoyancy and are ejectable to attain negative buoyancy. 



PROPULSION/CONTROL: Five 5hp, reversible MK 34 torpedo motors (DC). Two are mounted astern for forward and reverse propulsion, one is 



mounted athwartships to provide lateral thrust, two are mounted amidships on each side to provide vertical thrust. Four degrees of freedom from 



thrusters plus two degrees by internal ballast trim are attainable. 



TRIM: Ballast plate drop or buoyancy block ejection for adjustment to buoyancy status. Internal movable ballast for pitch or (infrequently) roll 



trim. Fore and aft ballast plate drop determines pitch/trim external. 



POWER SOURCE: Sixteen 6-V, lead-acid batteries connected in series-parallel provide 12, 24 and 48 VDC at 220 amp-hr for main power. 



Emergency power may be attained from eight 6-V, lead-acid batteries connected in series-parallel to provide 1 5 amp-hr at 24 VDC. Four auxiliary 



batteries for switching and environmental control have 2.4-kWh capacity at 24 V. 



LIFE SUPPORT: Two each, 18-ft^ tanks of Oi; two each, 18 ft^ tanks of scuba air. Ot, COi, HtO, and temperature monitored visually with 



warning horns on Ot high and low and CO2 high. Primary CO2 removal by LiOH, backed up with Baralyme, 



VIEWING: Glass hemi-head provides panoramic viewing forward. 



OPERATING/SCIENTIFIC EQUIPMENT: UQC (8.1-kHz) 4,000-yd range. Two depth gages, lights, echo sounder, VHF radio. 



MANIPULATORS: None. 



SAFETY FEATURES: Jettisonable battery pods and ballast plates. Access trunk can be blown for 100-gal displacement (855-lb buoyancy). 



Emergency batteries internal. Redundancy of blow or pump for access trunk. Flood and go possible with portable scubas. 



SURFACE/SHORE SUPPORT: SOO 



OWNER/BUILDER: U.S. Naval Undersea Center, San Diego, California 92132. 



REMARKS: Not operating. Certified to 100 ft. Now at Southwest Research Lab.
