To '''execute''' a naval invasion, a country requires '''more than 50%''' ''naval supremacy'' (also called 'naval superiority' in some tooltips) '''in all [[Strategic region|strategic regions]]''' (sea zones) in which the divisions will need to traverse the sea en-route to their destination. These are the regions the arrow of the naval invasion battle plan passes through.

To be able to get ''naval supremacy'', you have to have at least {{hover|NIntel.NAVAL_SUPREMACY_INTEL_LOW|30%}} [[#Naval intel efficiency|naval intel efficiency]].

''Naval supremacy'' of a navy depends on what '''type of mission''' it is running, how '''effective''' it is on the region, '''how many ships''' it has and '''how large''' they are.  
+
''Naval supremacy'' over the region depends on the amount of ships on missions by the opposing sides, with a multiplicative bonus for air superiority. One fleet can simultaneously contribute to ''naval supremacy'' in up to 3 regions covered by its mission.
''Naval supremacy'' in a strategic region (sea zone) is the sum of ''naval supremacy'' of the taskforces assigned to it.

'''Larger ships''' contribute '''more''' to ''naval supremacy''. For example the italian early battleship ''RN Andrea Doria'' provides '''356''' ''naval supremacy'' on strike force mission. A single ''Curatone Class'' italian early destroyer provides '''117''' ''naval supremacy'' on strike force mission. ''Naval supremacy'' per ship is calculated as:
+
All ship classes contribute the same to the ''naval supremacy'' rating, a submarine being equal to a super-heavy battleship.
  
:'''''Naval supremacy'' of ship''' = {{hover|NNavy.SUPREMACY_PER_SHIP_BASE|100.0}} + {{hover|NNavy.SUPREMACY_PER_SHIP_PER_IC|0.005}} * ship production cost in industrial capacity (IC) + {{hover|NNavy.SUPREMACY_PER_SHIP_PER_MANPOWER|0.05}} * ship manpower
+
Ships on hold do not contribute to ''naval supremacy''. Otherwise all mission types contribute equally. Fleets on Patrol mission with Do Not Engage order contribute as well, even though they never engage in any combats.
  
Task forces with '''''Do Not Engage''''' order do not contribute to ''naval supremacy''.  
+
Maximum possible bonus from [[Air superiority|air superiority]] is +100% to the ship amount, making each ship count for two. It is achieved when air superiority is 100% and there are enough planes to cover 100% of the sea region.

''Naval supremacy'' is only required for a short moment to launch the prepared invasion. After that the invasion will proceed even without sufficient supremacy.

Once the invasion has been properly planned, ''naval supremacy'' has been attained, and sufficient convoys are gathered, the plan may be activated.
