tinuous environmental sampling, and quiet operation are 

 also essential. 



With these criteria, Electric Boat has made preliminar.v 

 designs for a submarine (fig. 27) that would be 163.5 feet 

 long (a few feet longer than the Totnisend CromwtU) , have 

 a maximum submerged speed of 20 knots, a surface speed 

 of 11 knots, an operating depth of 1,000 feet. The craft 

 would carry 7 scientists in addition to the crew of 24. The 

 vehicle would be unique in almost all respects. There would 

 be an 8-foot observation sphere in the bow with five windows 

 for direct observation. The scientific laboratories would 

 equal or excel those of surface craft. Equipment would 

 include: water sampler capable of delivering 15 water 

 samples simultaneously, hull-mounted instruments for 

 recording temperature, salinity, and depth ; a continuous- 

 transmission, frequency-modulated sonar; two inverted echo 

 sounders. Seven television cameras would be mounted on 

 the hull. In the stern laboratory would be placed a tube 



from which trawls, plankton nets, fishing lines, bottom 

 samplers, and other instruments could be launched while 

 the craft is submerged. 



The object of the submarine is to place the scientist in 

 the environment which he is studying. With it, he would 

 be less dependent on weather (most oceanographic opera- 

 tions are necessarily conducted in equable climes, although 

 the fish are less radically affected). The submarine could 

 study such oceanic features as thermoclines, fronts, cur- 

 rents, turbulence, and waves, where precise control and the 

 ability to hover or maneuver in three dimensions are needed 

 to define the features of the environment or determine the 

 relations among variables. A neutrally buoyant submarine 

 could accompany a particular water mass and measure its 

 changing physical and biological properties. There is little, 

 in fact, in observational oceanography that the submarine 

 cculd not undertake, and further uses will undoubtedly 

 present themselves when the craft is available for operation.
