No worries, it's understandable considering that your changes take some time to do. I don't know if you're Wikignoming because you lack the time or resources to expand articles or if it's just something you prefer to do, but there's certainly other stuff that you can be profitably be doing. Ship article titles need to have the ship's name in italics or you could focus on improving their categorization, neither of which I tend to remember to do anything about. Adding convert templates to articles is certainly worthwhile, although I'd suggest you limit your preference for always abbreviating everything. For one thing, I like to show the hyphen form of a compound adjective like 15-inch gun, something that abbreviating eliminates. You could ensure that articles written in AmEnglish use American spelling of units and vice versa; just be sure not to change the type of English unless there are strong national connections like RN ships use BritEng or USN ships use AmEng. Articles on non-English speaking navies' ships have no national connection and can be written in either form; just be sure that it's consistent within the article. And if you'd like to write a ship article, I'd be happy to help as I have a pretty large library; so much so that I don't really consider Jane's Fighting Ships as a top tier resource. Lemme know what you'd like to do and I'm willing to help or provide advice.
