What a standard naval refit actually includes

What does a standard naval refit include?

It is a broad inspection, repair, renewal, repainting, and modernization package that can amount to an overhaul of most of the ship.

A standard ship refit resembles an unusually comprehensive vehicle inspection and overhaul. Systems are examined, defective components repaired or renewed, and the hull and spaces repainted where necessary. Equipment can also be upgraded to keep the vessel relevant for the next phase of service. For an aging warship the result can approach a rebuild in scope even though the ship retains its identity.
