 Fishy 

Have a look at the Tautog infobox? It's showing ""struck"" rather than ""stricken"", & won't accept a change to that without wiping out the section entirely. Nor will it accept an add ""as built"" without putting it in a weird place...   
It appears that it's using a different infobox template than the other related submarine articles that uses ""struck"" instead of ""stricken"" and doesn't have an ""as built"" field.  The infobox probably needs to be switched from the ""Infobox Ship"" to ""Ship Table Header 01"" as in the USS Thresher (SS-200) article.  "
