Subs are great to destroy enemy transports and support surface ships, but are incredibly vulnerable to destroyers. Convoy Raiding. Clouds or just bad luck made it very difficult for non-radar-equipped aircraft to find ships in large sea zone, and the number of aircraft that HoI4 puts "in the air" for anything other than carrier air wildly overstates the kind of persistent sortie levels that were actually capable at the time (in HoI4, all aircraft that aren't destroyed are. Submarines and Naval/Tactical Bombers to convoy raid and cripple navies from the air. Defensive (using the navy primarily for convoy raids and escorts. The destroyer patrols that kill subs get absolutely manhandled by Cruisers. To transport troops during wartime, you should have to assign them to escort fleet, or press "I really want to send them unescorted" button. Ships can influence land combat by. 6 Minelaying. Destroyers are good to protect your transports from enemy subs and sponge the firepower in battle, but ultimately fodder to cruisers. This means that it requires as many escort ships to cover 1 naval area from a trade route than to. ago. So! (2. Get the entire sub fleet up to level 3 (via exercise). 2. Look, the problem with naval combat in HoI4 is the same problem with land combat: Far too much of the tactical and operational levels of combat are abstracted and nonsensical.

Convoy raiding, where submarines eliminate unescorted convoys, but suffer huge targeting penalties when engaging a convoy with an escort. So your convoys aren't moving towards the enemy. No I dont have it at all, just tested again with the 1939 start this time and the exact same thing happened, AI finished all initial ships in the queue but never builds any after those besides convoys. Convoy raiding and escort give only 50% of the supremacy, compared to the full 100% of Patrol, Strike Force, and Naval Invasion Support. You can look in the hoi4 defines for "SCREEN_RATIO_FOR_FULL_SCREENING_FOR_CAPITALS" and will see that it equals 3.

And the way to do that is to invest in as many escort DD as possible to achieve mission efficiency (or air superiority). How effective enemy escorts are depend on how high their escort efficiency is, the higher, the quicker the escorts will. So cheapest gun, one of Beth depth charge, best radar/sonar/engine. So, in this guide, we will show you the best ship designs you can use in Hearts of Iron 4 to stop thinking about the Navy more than it’s necessary.
