This page allows you to lookup USS Ships for which we have philatelic covers in the collection. You can either look these Ships up by a filter on Ship name or by a filter on the Class in which the Ship resides. If you want all the USS Ships that start with the letter ‘H’ enter ‘H’ in the Ship field. If you want to see all the Ships in the Battleship Class then enter `Battleship` or `BB` in the Class field. If you see a black envelope next to a Ship, it means that there is a example of the cancel from the Post Office on the Ship in the system. Click on the black envelope to see the examples.
