It can carry a dry load of 690 square metres (7,400 sq ft) and can refrigerate 128 pallets of food. The ship is powered by two 10 PC4.2 V 570 Colt-Pielstick diesel engines that drive two shafts; this gives a power of 25.6 megawatts (34,800 PS; 34,300 shp).
The Henry J. Kaiser-class oilers have maximum speeds of 20 knots (37 km/h; 23 mph). They were built without armaments but can be fitted with close-in weapon systems.

On 23 April 2002, Walter S. Diehl was passing through the Strait of Hormuz when six small motorboats sped alongside in an aggressive and threatening manner. Walter S. Diehl fired flares to warn the boats off, but they did not move away. She then opened fire with a .50-caliber (12.7-mm) machine gun and the boats sped off.
