My naval estimation is just guesstimation
Based on whereabouts units will be.
Germanys fleet will be in the baltic, Battlship Cruiser Destroyer Transport 2x subs, another seazone with a Cruiser and a sub.
Italy will have a 2 Battleship and 2 cruiser fleet, and a cruiser + destroyer floating around
UK will have a battlship task force at Gibraltar and Liverpool. Other fleet elements scatterd about.
