Naval auxiliary vessels carry considerably less cargo than commerical vessels and are significantly more costly to build. By comparing Naval Auxiliary vessels with commercial vessels which carry cargo of a similar nature it is possible with the method used in this analysis to quantify and explain the differences which exist between the Naval Auxiliary and commercial vessels. 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 and practices used by Naval and commercial designers. The analysis is accomplished by comparing two Navy dry cargo replenishment vessels with three merchant break-bulk cargo vessels and by comparing 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 vessels, particularly with the oilers. Differences in design criteria and practices used by Naval and commercial designers are reflected mainly in the structural and main propulsion areas. (Author)
