E-8 



WRL SYSTEM 



Operating Depth : 6,096m (20,000 ft) (cable length is limiting factor) 



Dimensions (LxWxH) : 190cm x T9cm x T6cm (75 in. x 31 in. x 30 in. ) 



Weight (Dry) : iTTsUkg (2,500 lbs) 



Toy Speed : 1 knot (2km/hr) 



Power: Fish power is supplied by an onboard 20 amp, nickel-cadmium, 



28 V battery. The battery is maintained in a fully charged condition 



throughout the towing operation by supplying current from the support 



ship through the T,315m (2l|,000 ft) of cable. 



Instrumentation: CCTV (slow scan), two 35nim still cameras (105 and 6? 



degree viewing angle), TOmm still camera, side scan sonar, proton precision 



magnetometer, altimeter (sonar). Roll, pitch, heading and speed sensors. 



Optional: water temperature sensor, pressure/depth, radiation detector, 



multi-sampling water bottles. 



Navigation: A surface-oriented, short baseline system is used in 



conjunction with a responder on the fish. A bottom-oriented transponder 



navigation system is also available. 



Crew: Six minimum at all times, 12 required for 2k hour continuous 



operations. 



Support Ship Requirements: The system was designed to be employed from 



a dedicated ship, USNS MIZAR (T-AGOR II). It could probably be operated 



from other AGOR-type ships, having appropriate handling capability and 



characteristics, winch, computer, deck space, etc. 



Status : Inactive (Maintained in a state of semi-readiness)
