When nuclear power suits a surface warship

Are nuclear-powered surface warships worth their cost, and what advantages and limitations matter?

It depends on the navy's mission: exceptional range and electrical power can justify the expense for a global force, while a regional fleet gains much less from the same specialist burden.

The answer is conditional because nuclear propulsion is not inherently superior for every surface fleet. Its strongest benefits are exceptional range, sustained high speed, and dense electrical generation for weapons such as lasers and railguns. Integrated electric propulsion also broadens how reactor output can be distributed around a ship. Those advantages matter most to a navy maintaining continuous global presence or demanding very high onboard power. A regional fleet receives none of a submarine's stealth benefit from the reactor, yet still has to fund specialist training, maintenance, and infrastructure.
