Notes I made for myself to try to understand the navy systems.
 
 

Hoi4 Navy Notes

Doctrines left to right (Battleships – Cruisers and subs – Carriers)
 
 
4 screen for 1 capital (1 Carrier 1 battle ship 8 destroyers(2-4 light cruisers)
 
2 Capitals with 1 Carrier
 
Keep carriers with a large force (Bad at ship v ship)
 
 
Always have air superiority (planes hurt)
 
 
Light guns kill screens (small protective ships)
 
Heavy guns kill Capitals
 
Heavy ships aim for heavy ships
 
Small ships aim for small ships
 
 
Torpedos ignore armor depend on screening efficiency of enemy (Dead screens=Dead Capital)
 
 
30-40 subs(main fleet) / torpedos destroy large ships once enemy screens reduced
 
Convoy Raiding with almost all subs (20-50) subs per task force (For good damage and raiding efficiency)
 
 
Don’t neglect naval research
 
Radars Good (For ships,army, and air)
 
Fire control is also good
 
 
Consider the buttons (engagement risk, automatic reinforcement, etc…)
 
 
Stike Force To conserve fuel, but retain naval supremacy
 
Small spotting fleets to call Strike Force
 
Small anti sub Convoy Escort
 
 
Mines and mine sweeps are good
 
AI almost never does either
 
Mines cause lag though
 
 
Make different theaters for clarity (Raiding – Mainfleet)
 
 
Its okay to not do the top modules/ use cheaper modules for top
 
Speed is very good. can make a surface fleet that raids (with light guns)
 
Light fast cruiser with fodder destroyers and torpedo destroyers
 
 
Check naval losses in ledger
