Dear Al

There is a short entry for the AN/WLR-6 in the "Jane" for 1979-80.  The 
manufacturer was GTE-Sylvania.

It states that the AN/WLR-6(V) is a highly sensitive and versatile radio 
receiving system installed in submarines to intercept, analyse, record and 
evaluate electro-magnetic signals.  The system handles manual morse, 
radioteleohone, radio relay and printer, radar and tty signals.  The system 
includes rf distribution equipment, receivers, analysis and demultiplexing 
equipment, display equipment, DF gear, teleprinters, tape recorders, signal 
monitoring and distribution kit.

It is configured in five operator positions situated in the sub's radio and 
ECM rooms.

In 1965 Sylvania developed a prototype system consisting of 210 units for 
major sub-surface reconnasaonce.  Each consisted of 23 racks with over 200 
units of various equipment.  A total of 49 systems had been delivered.

Al's link to Wiki shows that a number of US Sturgeon class subs had their 
hulls lengthened by 100 feet to accommodate ELINT gear.  One hesitates to 
think of the cost of this lot to the US Treasury.

Hope the above is of interest.
