Hello, I'm Callanecc. I noticed that you made a change to an article, Typhoon-class submarine, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Callanecc (talk • contribs • logs) 04:33, 22 August 2021 (UTC)
