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
