Lend lease of equipment and tanks to allies also use convoys and this material can all be lost to the bottom of the ocean when faced with an efficient submarine net.'Д¬heck out the latest developer diary for more on Hearts of Iron IV's naval gameplay.Hello everyone, and welcome to another dev diary! In April we showed you a first sneak peak teaser of the new missiles system. 'Convoys are extremely important and transport both replacement equipment to oversea battlefields, supplies and resources so hurting them will have a large effect, sunk convoys can't be instantly replaced either so active defense is necessary, you cant just try to outproduce the enemy's sinking. The way the strategic area mission system works also allow you to use surface raiders, like how Germany historically used its few heavy cruisers to tie up and frighten the British navy.' 'In HOI3 it never really felt like submarine warfare had enough impact and we want to fix that in HOI4 and force nations to have to spend resources to counter it. The team is also looking at submarines so they have a greater impact on supply lines.

It's certainly a more realistic approach to naval warfare, and will hopefully prove a lot more interesting in Hearts of Iron IV when it releases. Naval battles in HOI4 can simulate longer affairs where ships join over time as the rest of the fleet rushes to help,' continued the developer. Depending on how spread out the fleet is, doctrines and luck its going to be a smaller part of the fleet that makes initial contact. 'When fleets find each other or convoys of the enemy naval combats will trigger.

в–Є Hold - Not really a mission, but can be useful for ships like Carriers that you want to just position like a floating airfield. в–Є Invasion - used to control large scale land invasions. в–Є Convoy Escort - Protect any convoys in an area from raiders.

в–Є Convoy Raiding - Focus on raiding convoys and avoid engaging warships. Suitable for trying to force large fleet vs fleet battles, say like the Battle of Midway. в–Є Search & Destroy - Much like Patrol but less efficient at searching while keeping the fleet together more. в–Є Patrol - Focus on finding the enemy as efficiently and as spread out as possible We'll cover those in detail in a future diary, but as an example if you pick the Trade Interdiction doctrine you can unlock Wolfpack tactics which will make sure your subs find more targets and can all get together and strike more often.' A single screenshot is also posted, revealing the new look to naval fleets. 'Things like how fast fleets of a certain composition can converge and how well they can search in an area is controlled in large part from Naval Doctrines. In general a more spread out fleet can cover more area and have a higher chance of finding the enemy, but will take time to concentrate its forces and bring them all to bear,' explains the latest developer diary from Paradox Development Studio. When in a strategic area each fleet has a value indicating how spread out it is. 'Just like the strategic air war navies spend most of their time on missions in strategic areas, but are also able to move province by province. Missions define exactly how they behave, and who they target. We now get indicators to tell us how spread out our fleets are in an area, with Naval Doctrines having significant impact on their efficiency. Fleets can still move from province to province, says the developer diary. Naval fleets in Hearts of Iron IV are getting an overhaul and will now, it seems, act more like the air forces which operate in specific strategic areas.
