The command infrastructure behind D-Day fire support

How was naval gunfire support coordinated during the D-Day landings?

Specialised command ships, modified landing craft, and layered control teams connected requests from ashore to the ships that could provide fire.

Specialised frigates, modified landing craft, and multiple command teams made fire support far more than a simple ship-to-shore firing arrangement. That infrastructure connected requests from the beaches to the naval guns that could answer them. Its scale also helps explain why a cross-Channel invasion was much harder than simplified comparisons suggest.
