[Milsurplus] Who is GHS?

[Jim Whartenby]

I have an ARC-65 antenna coupler with a white stenciled logo of a vertical missile next to a horizontal submarine with the capital letters GHS below the submarine.  Does anyone recognize this logo?
I suspect that the original ERA antenna couplers , see: http://vipclubmn.org/couplers.html which were built to work with the AM modulated ARC-21 were later modified for use with the SSB ARC-65 upgrade to the ARC-21.  If this is indeed the case, this work was carried out by GHS.  Could this logo be for Sperry Marine Systems?  That would explain a submarine logo on a piece of Air Force avionics!

 I wonder why people argue over the 10% of their differences and ignore the 90% they agree on?
