Well, I can't find the smootage for this Heavy Gun Cruiser, the USS Chicago, but it clearly is a doozie:

AND there's another shape similar to this in storage at Bremerton. Links later.

This ship was built over in Camden just as was the New Jersey. It was converted in the 1960's to a Missile Cruiser.

So, is the mysterious Keyhole Flying Dutchman one of these?

Stay tuned!
