DRV ALUMINAUT 



The deep-diving submarine ALUMINAUT, owned by Reynolds Submarine Services 

 Corporation, was launched at the Electric Boat Division of the General Dynamics Corpora- 

 tion in September, 1964. ALUMINAUT is an 81 -ton submerged displacement submarine 

 laboratory capable of carrying her operating crew of three or four men and three or four 

 scientific passengers with scientific instrumentation payload of 6,000 pounds at an average 

 speed of 2.5 knots for dive durations up to 30 hours. 



ALUMINAUT has a design depth of 15,000 feet, with a safety factor of 1.5. The max- 

 imum depth achieved is 6, 250. feet in 1967. The 8-foot-diameter pressure hull is made of 

 6.5-inch-thick aluminum alloy. Four silver zinc alkaline batteries provide power for all op- 

 erating and scientific electrical loads. ALUMINAUT, which is 51 feet long, has four viewing 

 ports. A hydraulically powered, two-arm manipulator is installed on the forward section of 

 the keel. Maximum reach of each manipulator is 109 inches; at this length, lift capacity is 

 200 pounds each. 



Additional facts include: 



Normal dive rate: Descent - 100 fpm. 



Ascent - 100 fpm (average). 

 Maximum deadweight lift capacity: 8,000 pounds plus. 

 Emergency ascent techniques: Release 4,500 pounds ballast bar. 

 Surface communications: 75-watt, six channel radiotelephone. 

 Submerged communications: Straza UQC.
