The cost comparison between rebuilding Renown and ordering a new capital ship turns on the value of the existing structure. A reconstruction can replace machinery, weapons, and internal arrangements while retaining the most expensive parts. The work remains complex, but it avoids buying a complete new armour scheme and hull from scratch. Armour already embodied in a ship is another form of industrial reserve, provided the hull remains worth modernising.

Why a major rebuild can cost less than a new ship
A major warship rebuild can be expensive but still compare well with new construction because it preserves existing armour and structural material.
