HOI4 Dev Diary - Airplanes and Lootboxes

Hi everyone! Today’s diary is sort of a logical continuation on the 1.4 “Oak” updated where we did a full revamp on the air interfaces and much of the underlying combat mechanics. So lets dive into some more air stuff!

Attaching air wings to armies
It's now possible to attach air wings directly to armies. This means that if you assign them to an army pushing into a hostile nation those wings will get automatically move to bases in range and assigned to areas the army is fighting in. This should hopefully mean no more accidentally forgetting your air force in france when you move forces up to the russian front in hectic multiplayer games or needing to manage things manually when crossing into new areas under an advance.
Assigned wings show over armies in air mapmode (you can’t attach to army groups) for easy check on how your attached air forces situation is. We show them in 3 groups: Fighters, Close Air support/tactical bombers and Transports for supply. You can’t attach strategic bombers, because, well, having planes on order to destroy the area you move through is generally not good. You can also quickly select those planes in each group which makes sending them around and rebalancing easy and quick.
Attaching is a free feature for everyone as part of the 1.5 “Cornflakes” update. The rest of the diary will cover features in the upcoming (and still unannounced. Trust me I’m itching to tell!) DLC.

Air Supply
Ever had your troops encircled and out of supply and wished there was some way to help them out? Now you can assign your transport planes to bring supply across enemy lines. Each plane assigned to a strategic area will boost supply in supply areas there. These planes can be intercepted as any other mission resulting in less supply, and destroyed planes. Air supply is designed to be a costly thing that you only want to use at a smaller scale, or to adjust minor supply problems. To ensure this we are rebalancing transport planes a bit so you will need a lot more of them (although with reduced costs as their “air fleet” status right now works badly with being intercepted) and air supply being a logistically tricky affair will require tying up new country resource to work. More info on that in a later diary though when we can show the whole picture. What is important here is that it's hard to use this at a large scale, and that it will come with some trade-offs.

To make it easy to identify where to send your transport planes on supply missions the air mapmode now has a special indicator showing areas with a supply need where planes could be assigned. If you are over supplying them through the air this is also shown, so that you may want to withdraw some of your wings.

Prioritization for strategic bombing
Players can now affect target selection for strategic bombers. The way it works is that you mark your prioritized targets when picking the strategic bombing mission. Those building types selected will have a higher chance of being targeted compared to others. Bombing isn't the most exact process and we felt it would be weird if you could completely control what doesn't get hit etc. So instead we decided on a system where you can somewhat affect it, but won't be able to walk into an area with all refineries destroyed but pristine infrastructure and factories.

We also have one more air related feature as part of the DLC, but we will be showing that off in a future diary where it fits in better with the content there ;P

Next week is a diary I have been looking forward to - we are going to explain what that new topbar button does that you may have spotted in screenies :)

PS. The second episode of our beginner-stream with @Da9L and @bus is coming any second now. Even though most of you are probably familiar with the basics, this is perfect for any friends that want to join in. Check out the Paradox twitch today at 16:00 CET: https://go.twitch.tv/paradoxinteractive
 
Well, and I'm asking why block using air attach into Army Group. It isn't so different mechanically, I believe (?), and you can stretch an army for two air zones as well. Can't say any other reason.
it makes it more unclear where they should focus, and one of the reasons to use attach to army. The army group cant directly control its own units.

I'm hoping they finally decided that just shoving every plane into an air zone is neither a realistic nor a fun way of playing.

Unfortunately they probably are just reviving the relocation mechanic, although the fact they're testing the assigned wings only participating in their assigned army's battles gives me a lot of hope that they're looking towards the right direction. We'll see.

Personally I like not attaching to an army group, as you'd again just assign every general under an army group and then attach all your planes to that army group.
 
Won't this make Sealion even easier? You can already overrun England in 1939 with some well-placed paratroopers, imagine if they were being supplied from the air as well?
The fact that the British AI usually abandons most of the UK certainly helps. Again, this is one example of how the AI results in something that should be fun and challenging just feel slightly depressing.
 
How does this affect paratroopers? Can you send paratroopers with transport planes attached from any airport, without having to manually move transport planes to that airport?
 
We are testing them only joining the attached army's combats, but might not be something we go with in the end depending on results so I didnt mention in the diary

This seems like a bad choice - so the planes instantly pop into the air as soon as any division is attacking or defending? This will also nerf manual placement of airwings into airzones, since having the planes in the air all the time manually means that they are subject to crashes etc. It will also look weird in the airzone view mode, with planes popping in and out each microsecond...

Overall from a MP perspective, this and the infrastructure changes from earlier DDs represent a huge buff to Strat Bombers. Allies and maybe even Axis will want to have a dedicated Strat Bomber player.

I'm interested to see how the air changes from this DD impact the current MP meta of having a dedicated fighter Hungary and fighter Canada on each team. Mostly I hope that the airzone mode shows the breakdown of the Allied planes in the air (right now it only shows green/red, doesn't tell you the numbers of types of allied planes, even though it does so for enemies) and also allows allied fighters to escort allied CAS.

To be fair, the AI puts more effort into this than a lot of people on multiplayer games. I've seen people leave the UK empty a year into the war.

I guess they mean that the planes will be flying over the air zone (day and night/day/night depending on what you assign) and will participate in battles, but will only affect the ground battles you assign them to.

MP is different in that people tend to opt for the 'gamey' option rather than the realistic/historically plausible one -- if they think no one is going to invade (or it has been agreed among players that no one will) then there is no reason not to ship everything to France, North Africa or S.E. Asia.

However, the AI should not be thinking like this, and when I decide to launch Sealion I don't expect to find an abandoned UK... it doesn't make sense, and it's not something that would ever have happened historically. It's just sad =/
 
YES! FINALLY! AIR SUPPLY! LET OPERATIONS OVER THE HUMP BEGIN! And the 101st don't have to worry about starving to death anymore!

I really like how Air Wings are attached to armies now, and with the changes I think I can actually use strategic bombing for something, not just for launching nukes. Awesome work, guys!

When I did Sealion in 1939, I used momentary air superiority to paratroopers in an empty province in the Great Yarmouth kind of area, which caused Britain to move a division away from the Thames estuary. Then I dropped a second lot of paratroopers in Essex, captured the port and sent in thirty German divisions which made short work of the British forces there.

It wasn't so much that Britain had abandoned the home islands, there was considerable resistance. Not enough to stop a massive German land invasion with armoured and motorised divisions, but enough to stop me from just raiding them with paratroopers or marines. The problem was more because they decided to abandon a crucial strategic location in order to deal with some hopeless out-of-supply divisions trapped in a useless coastal province. If France has just fallen and the Germans are landing airborne units in the southeast, why would the British decide to abandon their posts? If anything, a successful German airborne assault would mean even more British units moving south to garrison the entire coast against the invasion that's obviously about to arrive.
 
@podcat

What about area that has nearly no airbase and the airplane wings that are attached to armies in middle of this. What happens then? Will they try to fit 500 airplanes into a 100 airport or something silly?
