USNS Walter S. Diehl (T-AO 193)

- Military Sealift Command -

no coat of arms

USNS WALTER S. DIEHL is the 7th ship in the HENRY J. KAISER - class of 18 underway replenishment oilers. This class was specially built for the MSC.

On April 23, 2002, the WALTER S. DIEHL was passing through the Straits of Hormuz when the six small power boats sped alongside. Since the DIEHL does not look like a warship it probably appeared to be easy pickings. The DIEHL fired flares to warn the small boats away, but the boats did not back down and a gunner opened fire with a .50-caliber machine gun. The DIEHL's gunner kept firing as the ship moved ahead and the small boats then sped off.
