Scale model of USS Sampson D-63 at the
Navy Memorial Museum, Building 76, Washington Navy Yard, Washington, D.C.
circa 1973-1975
Note how the waist 4" (10.2 cm) guns could
fire directly forward if necessary, but that this position also meant that
they were difficult to work in a seaway
Gun directly forward of the bridge is
probably an Automatic 1-pdr on an AA
mounting

USS Greer D-145
Note the "bandstands" between the funnels
on this later destroyer, which allowed the 4"/50 (10.2 cm) guns on these
high platforms to be worked in almost any kind of weather, an advantage
in the North Atlantic
On 4 September 1941 USS Greer became the
first US warship in World War II to attack a German U-boat, U-652

Overhead view of the twin mounting on USS
Stockton D-73
Note the cramped working conditions when
this mounting was trained abeam. At least USS Hovey DD-208 and probably
USS Stockton and USS Long DD-209 had hinged sponsons added around the bow
mounting to increase the working space.
