"We know too little about this region!" Supremacy Oddities

[Colonel_Kraken]

I'm getting this message in three sea regions in which I have significant naval presence, including patrols, convoy escorts and strike forces at the ready. The message even shows I have far more naval presence than the enemy, yet I still "know too little about this region" ? My naval supremacy is 0%? How can that be? Can someone please help explain why I am getting this message and how to alleviate it?

Thank you

This has become kind of a FAQ since the release of 1.9 Husky and La Resistance DLC. Instead of parroting the same answers once again, I'd like to ask you to please read the past discussions on this subject, provided by the following links:

Naval superiority search results
Naval intel search results

The threads are sorted by date for your convenience. Ignore threads older than March 2020.

The issue is a bug or an obscure game mechanic or an extremely unhelpful UI, depending on whom you ask or how you look at it. YMMV if you have the La Resistance DLC, or not.

Your intel efficency is below 30%. You need at least 30% to be able to have naval supremacy. Below 30% it will always be 0.0% regardless how many ships you have there.
That's why the tooltip says "We know too little about this Region"

How to get more "naval intel efficiency"?

I think you get it, when you fight the enemy navy. So you could try convoy raiding.

And some quick tests seem to indicate that you get it by researching Decryption techonlogy:

• Decryption1: +30% naval intel efficiency
• Decryption2: +15% naval intel efficiency
• Decryption3: +15% naval intel efficiency

If your enemy researches Encryption it seems to reduce the bonus Decryption gives for you.

All players who understood that "You need at least 30% naval intelligence efficiency to be able to have naval supremacy" before reading Simon's response, are eligible* to enter a drawing to win a pony!

(*) Participants must not have had prior knowledge of 30% rule by way of reading this forum or the wiki. Proof of acquiring knowledge by playing the game required. Simon and bitmode are disqualified because they cheat. Void where prohibited. This post is a joke.

(haha, funny, Mousetick ;-)

Thank you, Simon. I did not know that. It seems odd to me that you can have several patrol groups looking for ships, and it says I have 0% intel. You would think the very act of patrolling (especially, including scout planes and carriers with planes!) one would have some knowledge of the region.

Could you please show us where is this "You need at least 30% to be able to have naval supremacy" info shown in game?

Also, what if I'm having a war with two factions? Which faction is my 'enemy' when naval intel efficiency is calculated? These two factions are not allied.

As far as I know it's not shown in game.

In the defines ( Hearts of Iron IV\common\defines\00_defines.lua ) you find:

    NAVAL_SUPREMACY_INTEL_LOW = 0.3,                                -- we need more intel than this to get any supremacy

 

[Mousetick]

@Simon_9732495

By the way, in your list of decryption techs

• Decryption1: +30% naval intel efficiency
• Decryption1: +15% naval intel efficiency
• Decryption1: +15% naval intel efficiency

They're all 'Decryption1'. I guess, you meant to write Decryption 1, Decryption 2, Decryption 3?

 

[Simon_9732495]

Yes. My mistake. Corrected it.

Thanks.

Despite this one, I have another question.

I had all three decryption researched, but naval intel stuck at 25% with enemy's convoy sunk down by my submarines. I'm having a war with both Soviet Union and Japan. Neither of them has a naval force larger than 40, or an active fleet on sea. How to improve naval intel further, without buying La Resistance DLC?

Which DLCs do you have?

Try building radar(s) covering the relevant sea regions. Radar is supposed to increase intelligence. Overlapping radars are supposed to increase the effect even more. This was true before version 1.9, it's unclear to me what effect radar has on intelligence in 1.9 and later.

Are you waiting to get 50+ % naval supremacy in order to launch naval invasions? The naval intelligence obtained from naval combat decays rapidly over time. Launch your naval invasion battleplan orders and wait while they are pending due to insufficient naval supremacy. At some point later, if you're lucky, you will encounter more enemy convoys or ships and engage them in battle, which will increase your naval intelligence above the 30% threshold, and in turn give you naval supremacy. Consequently the naval invasions that you launched earlier will start automatically. This has worked for me on a few occasions (I don't have La Resistance DLC either). YMMV.

Otherwise I'm afraid you're S.O.L.

 

[Simon_9732495]

Also, what if I'm having a war with two factions? Which faction is my 'enemy' when naval intel efficiency is calculated? These two factions are not allied.

I think it works like that:

Intel is calculated based on your enemy.
The base is

• 10% for facist, 12.5% for communist, 20% for democratic and non aligned

AND

• 20% for free trade, 10% for export focus, 5% for limited exports and I guess 0% for closed economy

So you have a base 40% for USA, base 30 for UK, base 22.5 for Soviet Union and base 15% for Germany, Japan and Italy.


For the seazone it is relevant who has ships on mission there.

• If there are NO ships from nations you are at war with on missions, you have 100% intel efficiency in the sea zone.
• If there are ships from nations you are at war with on missions, you get the intel efficiency of the enemy that has ships there.
• If more enemy nations have ships in the seazone it gets complicated... (I think some weighted average)

No place for me to build radar stations that can cover that area.

Naval supremacy became normal after Japan surrendered, so I guess bug is caused by them. They had zero convoy for some time, but they couldn't resist to surrender after two nuclear bombs. My naval invasion to Soviets started after that. There is some more bugs after that, but it's off this topic.

========== if you're interested ============

I had two wars that time, one is with Japan, one is with Communists, including Soviet and Socialist Republic of Germany.

I had 24 divisions on naval invasion, from a harbor in Korea to shore of Soviets in far east. After Japan surrendered (becoming a supervised government), naval supremacy becomes normal, so invasion should launched. But, Korea is liberated after Japan-China peace conference, and they refused to give me military access. Weird things happened. Some of my army decided to go the nearest harbor on my territory, others launched the invasion. When the invading divisions were closed to the target shore, they turned back, for no reason.

Weirder thing at that time, Japan was capitulated to German shortly after surrender. Meanwhile German was cornered by my faction on the Europe land. My allies took back Japan very quickly, because there was no single enemy division there.

I just tested it again once with all DLCs disabled and once with all DLCs enabled.
If I research Decryption1 I get +30% Intel efficiency everywhere.
Do you have any Mods enabled?

 

[DiscipleP]

Which DLCs do you have?

Four DLCs in mobilization pack.

• If there are NO ships from nations you are at war with on missions, you have 100% intel efficiency in the sea zone.
• If there are ships from nations you are at war with on missions, you get the intel efficiency of the enemy that has ships there.

It doesn't explain OP's screenshot, neither mine. "Intel efficiency: 25.00%", "Enemy ships with order to engage: 0"

 

[DiscipleP]

No mod. Only base game and 4 DLCs. Regular difficulty, no main country boost, ironman mode.

"Enemy supremacy" is not 0. Some nation has something there. And you have 25% nval intel efficiency of that nation .
What "Enemy ships with order to engage" means is another question.

Are you really sure that you researched decryption? (Not encryption) That works for me with all DLC combinations I tested so far.
What are your 4 DLCs? I can try exactly your configuration if you want...

But as you previously pointed out, the enemy's encryption counteracts the decryption. Isn't it what's happening to end up with 25% intel?
Did you have enemy supremacy and enemy encryption in your tests?

Yes, three decryption, on the right side.
