Subfixer,
And yet, the USS Pasadena (SSN752), the second boat of the third and last flight of 688, did not have them, at least when I commissioned her and served onboard her beginning in 1986. If the later boats of that flight do have them, I am happy to learn it. Indeed, if they have been added to the Pasadena, I would be glad to learn it! It just shows the importance of solid research.
Unfortunately, every model kit of every 688 class boat has this feature when, apparently, only the later boats of the third flight should have them. I remember showing one to my CO on the Pasadena when kits of 688's began to be released . . . he was aghast about the sternplanes having stabilizers on them. I can't count the 688 models I have seen with the vertical stabilizers on the sternplanes, even first and second flight boats. On a seperate note, the Ohio class SSBNs, should have them.
I'm glad you mentioned the propellor shrouds . . . that is a feature that has apparently been added since I retired in 1996. I retired off of the USS Maine (SSBN 741 Blue); she did not have a propellor shroud. It wouldn't surprise me if she had one now.
This brings to mind one other common error when painting U.S. nuclear boats . . . many builders paint the bow section of the hull below the water line a silvery color. This should not be! Red paint should continue around the bow.
