Did Dreadnought's advance stockpiling count as modular construction?

Does stockpiling Dreadnought's materials count as modular construction?

No. The materials were gathered before construction to avoid waiting for them, rather than assembled into large ship modules at separate yards.

The correction distinguishes stockpiling a ship's materials from manufacturing large sections of the ship separately. Dreadnought's armor, guns, and other supplies were gathered before construction so those items would already be available when required. That shortened the wait for materials without making the construction method equivalent to the distributed modules discussed here.
