It would make sense to build some extremely big dry docks covered with roofs so that when these phenominally expensive ships get old that they are not allowed to rust and rot. That with a high up roof on such a drydock as an older ship is potentially a military airport a power plant and large government building that could be in 70 to 90 years or more rather than cut it up for scrap in the distant future. Allso it would be an impressive thing for future generations to see or visit. Such drydocks would allso be usefull for maintenance of other Navy Ships.If most old Navy ships are eventually cut up for scrap it is an expensive waste.
