German high-pressure machinery is criticised as exceeding what could be made reliable in service. Prinz Eugen provides an example in the comparison of German and American efforts to operate it. A design that looks attractive on paper still has to survive its operating environment. Sea service imposes conditions that a land-based engineering approach can miss. Salt water's direct corrosion is one concrete difference raised in a comparison with spacecraft engineering.

Why advanced machinery still has to work at sea
Machinery performance on paper does not establish reliability in a corrosive marine environment.
