WALTER S DIEHL T-AO 193
Ship Name and Designation History
This section lists the names and designations that the ship had during its lifetime. The list is in chronological order.
Keel Laid 7 August 1986 - Launched 2 October 1987 Christened 10 October 1987 |
This section lists active links to the pages displaying covers associated with the ship. There should be a separate set of pages for each name of the ship (for example, Bushnell AG-32 / Sumner AGS-5 are different names for the same ship so there should be one set of pages for Bushnell and one set for Sumner). 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 name and/or commissioning period. 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.

NAMESAKE - Captain Walter Stuart Diehl (3 December 1893 – 21 November 1976)
Diehl was a pioneer of aerodynamics and aircraft design. From 1918 until his retirement in 1951, he directed the Navy's work in aerodynamics and hydrodynamics. He was responsible for the funding, programs, and facilities of the Aerodynamics Laboratory. The author of the authoritative "Engineering Aerodynamics," he actively participated in and strongly influenced continuing advances in aerodynamics and hydrodynamics.

Taylor Model Basin at Carderock, MD, the Aircraft Research Station at Chincoteague, VA, and the Navy's test flight unit at the Naval Air Station, Anacostia, D. C., which later developed into the U.S. Naval Air Test Center, Patuxent, MD.
