Least expensive way is to block naval routes where you'd be exposed and NAV bomb convoy raiders in areas you can reach until you kill the AI's raiding. Then select ships and give them a "support naval invasions" order and click every sea province between your port and where you want to land. 2 Strike force. A place to share content, ask questions and/or talk about the grand strategy game…Patrol = ships are out at sea searching for the enemy fleets and engage depending on engagement orders and enemy fleet strength. -Convoy raiding: submarines but any ship (or aircraft) is capable of inflicting severe damage on enemy convoys. I understand the AI wanting to sail across the. Naval warfare is conducted by ships which operate in the world's interconnected seas and oceans. Currently I have a fleet of just over 200 ships on convoy escort in the seas that the transports pass through and the Japanese only have a fleet of around 18 patroling those areas. 6 you can set a fleet to escort and it will fallow a naval invasion all the way to its target and then support the invasion till it's on the shore. Have naval bombers over all air zones in the Mediterranean. Damage should still be kept above 5. For invading the UK, stop all your naval missions so all your ships are in port. Escort efficiency: it dictates how efficient your screening ships are at escorting your convoys. 005 * ship production cost in industrial capacity (IC) + 0. ; About Hearts of Iron 4 Wiki; Mobile. There is two different variants that come in handy: First, Light/Escort Carriers (CVE). You can see the naval battle reports pop up as bubbles where the convoys (or any other ship) was sunk. 2. The base value is that you need 1 screening ship for every 2 convoys escorted. Yes!!!Yep working on it. For building up wider Naval superiority Destroyers, Light Cruisers and a few carriers per fleet (with 60/40 split towards Naval Bombers) will wreck most AI fleets. Contents. Patrols should be one ship each. Escort DD Those ones are made to defend your convoys. The German U-boat wolf packs were deployed in groups of 8-20 and the same should be true here for subs on convoy raiding. 0 + 0. CryptoCapital Ship Armor +10% ( Your capital ships will take less damage) Naval AA Attack +10% ( a very useful bonus against one of a capital ship's biggest threats) Capital Ship Attack +10% (I don't need to explain this) Minelaying Efficiency +20% (eh) Escort Efficiency +5% (this affects how quickly your ships can come to the aid of raided convoys)My invasion convoys were escorted by a fleet that was stronger than both the Formosan and Japanese fleets that engaged us. I'm short 700 convoys so at 4 a day I'll be caught up in a couple hundred but that's not all that fast middle of a war. For the first four, you need to pick the sea zones where you want them to do this task. Each class has different usage areas, advantages, and disadvantages. the dds low detection ruins your cls spotting. You can look in the hoi4 defines for "SCREEN_RATIO_FOR_FULL_SCREENING_FOR_CAPITALS" and will see that it equals 3. Cheap destroyers can be necessary if you want to trade resources overseas. The subs should have good torps and the best snorkel you have, and be split into packs of 8-12 (any more and there will be operational penalties). Patrol/Convoy Escort mission: CL and 2 DD fleet. Use the best engine and snorkel you can and then stack torpedoes until you reach 30 or 60 torpedo attack (which will allow you to sink a transport in 2 or 1 hits respectively). 7% increase in ship hp. I don't know the exact math but you want to kill ships in the shortest time with the fewest shots. Wait untill plan is ready. The secondary purpose can be AA -- by adding more AA guns, AE -- add extra secondary guns (the same size as a destroyer's main weapons), and/or. 0 unless otherwise noted. Then Japan has to send convoys to get them from Europe. I thought it was vanilla, but maybe its not. What are the uses of a battlecruiser. The point of a navy is to supply and reinforce land troops and keep the enemy from doing the same. Anti sub ships: destroyer model sonar depth charges Anti-air ship: destroyer or light cruiser model Radar AA guns ( no more than 3 which is already overkill) Anti-Screen ShipSo this has happened twice. Anti-Air II. Ironically I set my production to build 1 of each ship currently in production and decided to deal with it later when I have a free dock yards. Okay, so after lengthy experience with this. 48 votes, 21 comments. It’s really fun to see that happen. It’s really fun to see that happen. You can choose which sea zones to use, so if the enemy is attacking heavily in one, you can set the zone to red, or yellow if you need it for some routes. I personally divide my subs into 5 groups and set each group a target strength of 20 subs. have your entire fleet move to the channel as 1 group on convoy escort. You don't need air support you don't need bigger navy. [deleted] • 5 yr. As far as visuals go, convoys ALWAYS disengage automatically (except for bugs). Convoy Raiding is usually the purview of submarines, but if you have naval supremacy, (the UK or USA usually) you can use destroyers to do that too. Click a friendly port in the area and click the province you want to invade. General advice: always use carriers in groups of 4. Their survivability is in their speed. 1 Navy. They are treated more abstractly than all other ship types, with a variety of unique mechanics. Also split your SSs into small or big ship raiding task forces. 05 * ship manpower. 2 Patrol. Best ships for this job are the Screen ships (DDs and CLs) and carriers that should be able to intercept Air raids on ships. What's the best composition of ships to use for each Naval Mission (Patrol, Strike Force, Convoy Raiding, Convoy Protection, Minelaying/sweeping, and Naval Invasion fleets)? Last edited: Jan 16, 2022Best doctrine by far for most nations right now is convoy interdiction. I only convoy raid with the fleet to wipe out the enemy escorts. HOI4 Tools SGr - Save Game Recorder - records, compresses, and archives autosave files in realtime, no game impact. I sit there and watch as their DD's get right up to my convoys and start. Considering that the most popular convoy raiding fleets make good use of submarines, fans are going to want to use ships that can. Destroyers are good to protect your transports from enemy subs and sponge the firepower in battle, but ultimately fodder to cruisers. Surface ships make excellent targets for enemy fighters and subs so unless you have air superiority in the region expect to take some losses to your surface ships. In this I explain both the Convoy Raiding and Convoy Escort missions, and when a. bigschmokes. Writes: No Convoys Have Access. And for this effect it doesnt matte how good your ships are, all that matters is that they can theoretically sink a submarine. Ships can influence land combat by. It will not be a 88 but depending on how damaged the Cruiser is, it could technically happen. The Destroyer might be the most important part of a Navy in HOI4, as it acts as the shield of the Heavy Cruisers, Battleships, and Carriers. Commanded by a grand admiral, a thirty ship fleet with 10-14 capitol ships and 16-20 escorts. Ironically I set my production to build 1 of each ship currently in production and decided to deal with it later when I have a free dock yards. e. Like as a minor; I put the light fleets often in the same sector, one going for Hunt and Kill, the other on convoy raiding. They'll do the bulk of your ship damage for the first year or so.

For Patrols and Convoy escort. best way to convoy escort is Light cruisers and destroyers. I mean at a basic level, to launch an invasion you just select the units, select naval invasion, choose a friendly port and choose a target tile to invade. My patrol flotillas have 10 DD and 1 scouting cruiser, I build a handful of escort flotillas for convoy escort/sub hunting, and each battle fleet is usually 4 CV, 5 BB, 6 CA, 2 scouting cruisers, 12 CL, and 50 DD. Buuuuut a weak group raiding a convoy set to always engage will draw out the big boys and then boom your naval bombers know where the fleet is and tadah sinkin boats. The US needs to build both, whereas the UK doesn't really need as many subs. This is their preferred theater of combat after all. If they have AA guns they can shoot with them at other ships too. better to just use single ship taskforces for patrol set to never engage. addasher710 • 1 mo. That is where the possibility of a convoy escort comes in. To fix, click the icon that looks the exact same in the options for fleet managment at the top left of the screen. Commanded by an admiral, an eighteen ship fleet with 6-9 capitol ships and 9-12 escorts. 38. Once you have enough of those destroyers and light cruisers, one or two heavy cruisers and a few battleships you likely already have will absolutely slaughter most AI fleets. Pair that with cheap torpedo DDs and you can even brawl with the big fleets. Escort designer only brings that down to 52. Heavy cruisers also have the speed which heavier ships lack, making them far better and finding and killing enemy ships. Avoidance. Thing is, I have over 85% naval suppremacy in all the regions. Try to have all the latest tech researched before designing your ships. Focus on both carrier and regular naval bombers. hoi4: cheap irl: Most convoy ships were needed during the whole war for import and export unless they were blocked like the Germans. My patrol flotillas have 10 DD and 1 scouting cruiser, I build a handful of escort flotillas for convoy escort/sub hunting, and each battle fleet is usually 4 CV, 5 BB, 6 CA, 2 scouting cruisers, 12 CL, and 50 DD. ago. And even if you had max reduction then planes still shred ships. However, they'll be vulnerable if the enemy has a strong surface fleet and you might need a lot the get full cover. Germany didn't have to sink a certain quota of convoys before the allies actually started to suffer material loses. Escort carriers against subs work great and you can make them cheap. Mechanics for the naval missions come to mind. 1. Set to engage at high risk (sub3 or sub4 only). Ship management is important. I'm aware of the mistakes I made getting here, I'm asking if there is a way to optimize my convoys to get the resources I actually need. Planes however will join to protect them. Well, maybe if you had 40 destroyers, you might be okay, but it would have to be a lot. e. You can re-route convoys. The planner will say something about not daring to put our ships there. Secondly, the escorted convoy count is probably much higher than you were expecting. One group covering two sea zones should. Designed a 1936 destroyer: engine 2, x2 depth charge thrower, x1 light battery 1 and sonar 2… with no torpedoes, no fire control, and no AA. 5 IC per volley. ago. Could be escort carriers matched with old and new BBs The US Navy is stacked in the beginning of the game. JetSpeed10. increased number of convoys covered by each destroyer on escort from 10 to 12. The best way to defend convoys is 2 fold: defense and offense Defense: The best way to find subs is using air power and patrolling sea provinces. This is annoying. Even better if you're looking for subs in shallow waters where. The best way is to make Spotting Cruisers (cruisers with only Float Plane 2s on them) and pair them up with 5-10 Destroyers each with only Sonar and Depth Charges. Just like tanks piercing is everything for capital ships so you want more armor and piercing than your opponent. When escort efficiency is 100% among task forces within a given fleet, one of these task forces will instantly come to the defence of any convoys under attack within the fleet's assigned regions. 97% Naval Supremacy. Jan 16, 2022 Jump to latest Follow Reply What's the best composition of ships to use for each Naval Mission (Patrol, Strike Force, Convoy Raiding, Convoy Protection, Minelaying/sweeping, and Naval. The good news is that the AI has started blocking off the sea zones to convoy traffic where my subs and mines are doing the most damage. 1. Its also impossible to intercept supply ships heading to troops on islands even when you have a navy blockading the port. Naval warfare. So your convoys aren't moving towards the enemy. If it's for fighting, I upgrade I don't upgrade engine/armor, it's better to build a new shipIt enhances Search & Destroy for capital ships, submarine detection for screening ships, and bonuses for all classes, although subs seem least favored. The main consideration is how fast it takes a sub to wreck a convoy ship. Least strongest person from the Crete (he failed doing 100000000 push ups today and only did 999999999): TBF the game doesn’t say how many vessels are in a convoy, so those naval bombers might actually be facing dozens of. Cuz that 1% speed loss is statistically equivalent to a 1. Avoid shallow seas at all cost. And the way to do that is to invest in as many escort DD as possible to achieve mission efficiency (or air superiority). Submarine: cost per minelaying: 480 IC longer range: 2500 km very vulnerable to naval bomber Can raid convoy when needed Less visibility Destroyer: cost per minelaying: 380 IC (x2 slots), with AA: 435. And even if you had max reduction then planes still shred ships. You will catch and scare enemy convoy raiders this. The way to the capital is normal. Then make 4-5 patrol destroyer fleets for patrolling the seas.

Is AA an average number or is there a benefit of having pure AA ships. better to just use single ship taskforces for patrol set to never engage. 2) Run 1-3 serial builds of convoys constantly to replace losses. The reason that these are effective against the current meta is because CA's are counted as Capital Ships. To start convoy raiding just get a handfull of subs, maby a. Just convoy interdiction. Viriato_the_man • 4 yr. And the speed loss does affect your ships. Escort efficiency: it dictates how efficient your screening ships are at escorting your convoys. while a strike force or patrol might decide not to start an engagement in the first place based on strength comparison, a raider will always initiate battle against spotted convoys -- except on Do Not Engage. Indeed, worst part here, is that I had research the whole naval idea group the US starts with, guess thats a mistake. So! (2. Send them convoys and your early war tanks, then annex them. 0 unless otherwise noted. Subs are great to destroy enemy transports and support surface ships, but are incredibly vulnerable to destroyers. Control of the sea can facilitate naval invasions, or prevent the enemy from performing an invasion of their own. Harin said: I do not know off the top of my head the best way to tell where your convoys are sinking. Hev cruisers for cheap capital ship and massive light attack. my capital fleets consist of 3-4 carriers (with CAS wing included for land support), 4-5 BS, 5-8 heavy cruisers, 8-12 light cruisers, 24 destroyers, 2 submarines. Not quite accurate, ships set on patrol will still engage in battle based on their aggression. TLDR; Patrol = 2 to 5 good SS with radar or a few good light cruisers with radar/catapults. If your ships need to go for repairs or get pulled into combat, they are not counted as ready, pulling down your readiness percentage. Bigger is better. The enemy has simply closed the gap. HoI4 is dumb and doesn't punish naval troop movement nearly enough if it's port to port instead of an invasion, so you won't lose very many divisions, especially if a throwaway fleet eats hits for the convoys. Max radar is good. DD with max depth charge, radar and sonar. Naval strikes using only airpower never attack enemy convoys carrying resources or. Escort just those zones. Naval power is key to protection of convoy traffic, or disruption of enemy convoys. This means that the DDs on convoy escort are now slower than my. If I can use old ships for convoy escort, I don't upgrade them. they scout for enemey fleet groups, engage them, and sink enemy screens. First take the pacific fleet designer. Watch the AI get all its screening ships killed escorting convoys against battleships and then watch it sortie out 20 BBs with no escorts off the coast of italy. What should be the best option is destroyer with depth charges and sonars, maybe light cruisers to offset some those deep ocean malusses. These flotillas will convoy escort the naval routes you choose. Germany just sunk all of my convoys in 2 weeks. Subs are for convoy raiding Carriers if you away from your land-based air support. Spam cheap destroyers. Naval power is key to protection of convoy traffic, or disruption of enemy convoys. So forget submarine detection for escorts or expensive ships, simply spam old DD with 1. Set you sub fleet to engage at high risk, medium repair priority and enable automatic split off. Escort efficiency is lost when there is less than 1 screening ship for every 2 convoy. Stop trading for anything that takes convoys. ago. So, naval supremacy counts all ships "with orders to engage" in that sea region, including task forces on patrol in that region, on convoy escort, on convoy raiding, on naval invasion support, and on strike force missions. 38 votes, 13 comments.
