The scope of Phase I includes the ships themselves, and all ship classes. This includes, whenever possible, battleship and battlecruiser classes that did not make it past the planning phase but have sufficient information to warrant an article. This also extends to individual hulls that were laid down but not completed, if the hulls in question have enough information to warrant individual articles. Those ship articles with insufficient information for a stand alone article should be merged into their respective class articles.
