The sonar installations on destroyers have been difficult to track down. The equipment installed and the domes (different materials and construction methods) changed over the years and I have incomplete data on what each destroyer had installed. But, I think I finally got drawings with dimensions for the 100-in domes that appear to be "accurate", but not completely "engineering" style drawings used to manufacture them. For modeling purposes. I think they will do.
The dome is sort of elliptical in shape, but the forward "face" is shaped more circular and the aft end is tapered to a near point. Also, the bottom is shaped so it is "deeper" in the middle, but is more or less flat side to side with rounded edges.
The first two images/drawings, thanks to Ed Zajkowski from his collection, shows drawing views that come closest to understanding the shape of the 100-in long dome. The dimensions give you length, height, and width. Curve sections need to be "extrapolated"


These four views show the installation of either 100-in or 185-in domes on two different FLETCHER's. I the first two images are for a 185-in dome (more bolts) since that is what was installed on USS McDERMUTT (DD-677) and the bottom two images are likely for the 100-in dome.
