Twenty-eight of the U.S. Navy's WWI era cargo ships had one smokestack, two single masts, flush decks, and no or one kingpost pairs.
To facilitate identification, these vessels have been placed in sub-groups, some containing ships of essentially identical design ("sister ships"), while others consist of quite different designs. The latter are further subdivided as to whether they were built in the United States or abroad.
This page features a table (with links to individual ships) of World War I era U.S. Navy cargo ships with one smokestack, two single masts, flush decks, and no or one kingpost pairs, plus a photograph of each ship in this group.
