This section lists active links to the pages displaying covers associated with the ship. There should be a separate set of pages for each incarnation of the ship (ie, for each entry in the "Ship Name and Designation History" section). Covers should be presented in chronological order (or as best as can be determined).
Since a ship may have many covers, they may be split among many pages so it doesn't take forever for the pages to load. Each page link should be accompanied by a date range for covers on that page.

Postmarks
This section lists examples of the postmarks used by the ship. There should be a separate set of postmarks for each incarnation of the ship (ie, for each entry in the "Ship Name and Designation History" section). Within each set, the postmarks should be listed in order of their classification type. If more than one postmark has the same classification, then they should be further sorted by date of earliest known usage.
A postmark should not be included unless accompanied by a close-up image and/or an
image of a cover showing that postmark. Date ranges MUST be based ONLY ON COVERS IN
THE MUSEUM and are expected to change as more covers are added.
>>> If you have a better example for any of the postmarks, please feel free to replace the
existing example.

Other Information
USNS H. H. HESS earned the Navy Battle "E" Ribbon (4 awards) and the National Defense Service Medal during her Naval career.
NAMESAKE - Rear Admiral Dr. Harry Hammond Hess, USN (May 24 1906 – August 25 1969).
Hess was a geologist and United States Navy officer. Considered one of the "founding fathers" of the unifying theory of plate tectonics. He is best known for his theories on sea floor spreading, specifically work on relationships between island arcs, seafloor gravity anomalies, and serpentinized peridotite, suggesting that the convection of the Earth's mantle was the driving force behind this process. This work provided a conceptual base for the development of the theory of plate tectonics.
