Wikipedia:Naming conventions (aircraft)/2010 article renaming checklist

This is a master list derived from List of military aircraft of the United States to be used in conjunction with the updated aircraft article naming convention at Naming conventions (aircraft). Please append a tick: ✅ after checking or moving an article to an updated title, or a cross: ❌ for articles that have been checked and require moving but need discussion.

Once articles have been ticked as checked or moved they can be deleted from the page, this will leave lists with numbers missing however, the aim is to shorten the list until all the articles have been checked.

The ticking process can be bypassed if desired, i.e. if you are absolutely sure that an article is at the correct title then simply remove that aircraft type.

If in any doubt please do not move an article but discuss it on this list's talk page for consensus to be gained.
