Naval auxiliary ships carry considerably less cargo than commercial ships and are significantly more costly to build. By comparing naval auxiliary ships with commercial ships which carry cargo of a similar nature, it is possible by proper analysis to quantify and explain the differences which exist between navy and commercial ship design practices. The design differences and a significant portion of the cost differences are the result of differences in ship mission, the military capabilities of the naval auxiliaries, and the differences in design criteria used by naval and commercial designers. This paper compares two navy dry cargo replenishment ships with three merchant break-bulk cargo ships and a navy fleet oiler and a navy replenishment oiler with three commercial tankers. The largest factor which influences the design of the naval auxiliaries is the underway replenishment capability. The military capabilities also have a significant impact on the design of the naval ships. Differences in design criteria used by naval and commercial designers are reflected mainly in the structural and main propulsion areas. However, the impact of these technical differences is of secondary importance as compared to the impact of the performance differences in naval auxiliary and commercial ships.
