Building an amphibious flying warship in a naval yard

Would the air battlecruiser be built in a dry dock?

A dry dock is considered plausible at the stated size, and the fictional vehicle is described as built in naval yards and able to land on water.

The air battlecruiser's size makes a dry dock a possible construction site. A participant adds that naval-yard construction and landing on water belong to the fictional premise. That combination would strengthen a navy's institutional claim to operate it.
