Why captured modern warships are hard to use

Could a navy capture enemy warships and put them straight into service?

Sailing ships could often be reused, but modern warships became too specialized; a captured Yamato would require incompatible ammunition, maintenance, machinery support, wiring, and operating systems.

The Royal Navy retained the captured Italian auxiliary Zingarella until 1945, showing that a simple support craft could still be absorbed into wartime service. The discussion then draws a sharp line between the age of sail, when captured fighting ships could often be reused, and the ironclad-and-after world of complex machinery and national systems. Yamato is the extreme example: even a powerful battleship would bring engines, guns, shells, lubricants, wiring, and maintenance practices that did not fit the captor's fleet. The contrast shows why the usefulness of a prize depended on technical complexity and support compatibility rather than power alone.
