DEEP DIVER, a 1,200-foot vehicle, uses 

 both Vector and Electro Oceanics (EO) pene- 

 trators. An EO type penetration is shown in 

 Figure 7.17b (bottom) and Figure 7.18 shows 

 outboard configurations of the same penetra- 

 tor. The receptacle is essentially screwed 

 into a stainless steel insert and the cable 

 then connected thereto. A number of blanked 

 inserts are shown in Figure 7.18; these can 

 be used for additional electric penetrations 

 or whatever is required. Similar EO penetra- 

 tors are used on General Dynamics' STAR II 

 and the DEEPSTAR 4000. 



ALUMINAUT, designed for 15,000 feet, uses 

 three Vector-built and General Dynamics- 

 designed penetrators. The body of the pene- 

 trator is of 7079 T6 aluminum, the same as 

 the hull, and is a metal-to-metal seal. The 

 tapered body is held into the hull with an 

 inboard retainer nut. The connectors are 

 mounted to the outboard end of the penetra- 

 tor and comprise plastic bodies with the 

 plugs of molded rubber. Troubles at the out- 

 board plug-receptacle interface prompted a 

 redesign which is shown in Figure 7.17c.
