Blue sky doctrine sounds better suited for my preferences, at least for the first game where I intend to use wormholes. I'd assume that it's better for wormhole users in general, because you have to always worry about defense as a first priority.
On the Southern Front of the First Blorg-Just Alliance War, the Blorg confidently flew their shiny pre-war cruiser fleets out into enemy space and got more or less annihilated by the enemy's mass-driver corvette swarms. After these battles the enemy ground forces recaptured their planets and, had they not collapsed into a three-way civil war, could have counterinvaded into the Blorg's Party Zone.
The lesson we must draw from this is that a victory in your own space is as much a victory as one within enemy space. Whoever wins that naval clash can, if they wish, begin to destroy stations, bombard planets and land ground troops.
In my opinion, this leads to two opposing naval doctrines which would lead to different fleet builds.
Black Sky Doctrine
A Black Sky fleet is one which assumes that it will fight outside of its own borders. This may mean fighting inside enemy space, in neutral space or in the space of an ally. This means that:
- Be self-reliant. A Black Sky fleet cannot rely on the support of friendly defensive installations, spaceports or (if someone adds them in) system ships. This means that the fleet needs to be equipped to handle any given threat.
- Defence takes priority. Ships which are damaged will need to travel a long way back home. Ships which are destroyed will take time to replace. As a result, protection is important to a Black Sky fleet: a ship which is damaged enough to need to repair may as well have been destroyed.
- No ship is key. Because reinforcement is delayed, a Black Sky fleet which relies on a single specialised ship will be unable to fight if that ship is destroyed or damaged. This means that a Black Sky fleet would benefit from being made up of all-rounder ships in which no one loss cripples the fleet.
- You are always the big guy. Here's the nice thing about a Black Sky fleet: they get to choose where the battle is. If an enemy system bristles with defences, they can attack the system next door instead. Because of this, a Black Sky fleet is always going to be able to refuse battle if it wishes, and so only fight when they think they can win.
- Any time, any place. A Black Sky fleet gives the empire the ability to guarantee the independence of small nations, to intervene in distant wars, and to support her allies. Because they don't rely on support they can fight basically anywhere. A Black Sky fleet is a tool of diplomacy.
Blue Sky Doctrine
A Blue Sky fleet is one which assumes it will fight above its own planets (hence "blue sky.") This means that it can take advantage of repair, support and defence facilities. This means that:
- Stations allow specialisation. By fighting battles near their own defence stations, a Blue Sky fleet can shift some of the weight onto them. This means that ships don't have to carry their own fighters, anti-swarm weapons, et cetera, and can specialise in their own roles.
- Aggression is a virtue. Because repair facilities are nearby, a ship which takes 90% damage can be patched up soon after battle and is as good as new. Blue Sky fleets can afford to take more damage to their ships, which means they can put less defences on those ships and save the power for bigger (and more) guns.
- You need to be strong everywhere. Blue Sky fleets need supporting planets and stations in every system in which they fight. This is not only expensive but requires preparation; a scorched-earth strategy or a sudden opening of a new front can leave you vulnerable if you haven't been thorough enough.
- Be thorough. A Blue Sky fleet can go on the offensive once the enemy are destroyed, but needs to make sure they're destroyed. Make sure that you have ships and facilities which allow you to block FTL retreat and/or pursue fleeing enemies to wipe them out.
- Fight wave-based running battles. Because repair stations are nearby, a Blue Sky fleet can fall back and repair whilst other fleets hold off the enemy. By fighting with numerous small squadrons and rotating them in and out of battle, a good micromanager with a Blue Sky fleet can keep the pressure on. This allows them to wear down their enemies. The best ships for this sort of fighting will prioritise weapons over armour and will be able to withdraw easily.
Which one is best? The one that helps you in your circumstances.
Empires which are surrounded by enemies and expect to fight defensive wars, potentially against coalitions, should build a Blue Sky fleet.
Empires which are in a safe position and need to support far-flung allies or punish those who displease them, should build a Black Sky fleet.
It's not impossible that a large empire in a strategically interesting situation might build two fleets, one Blue Sky and one Black Sky, to enable them to defend themselves and also carry out expeditions.
What sort of doctrine do you see being appropriate to your empire?
I know, it's awful.It's almost like these forums are not a hive of scum and villainy.
If the AI aren't being cooperative and throwing themselves at your defences it could be worthwhile to send a raiding fleet into their territory. Sacrifice a few corvettes to find out what kind of weapons they're using and refit your doomfleet as necessary. Wormholes would probably be the best for this as well. The further into their space you can get your raiders, the more you'll delay them on their way to your space, the more time you have to refit, build up, or advance.Dark Blue Sky. Declare war. Hold single navy of doom at a central system within your empire. Wait until their war fleet to identify and show themselves, preferably by them engaging one of your vulnerable systems. If your fleet is weaker, then build/upgrade up fast. Let them attrition their way through your defenses. When ready, send out your force and chase them back to their lair, if not able to outright engage and destroy. Efficiency of strategy dependent upon speed/type of travel of fleets. Wormholes speculated to be most efficient.
If the enemy refuses to cooperate, send the ENTIRE fleet. Take one world, move on towards another and hope the enemy seeks to liberate the previous planet. In which case, abandon the second system and engage. Might as well make progress if the AI won't come to you normally.I know, it's awful.

Dark Purple Sky? I dunno, I am neither a space naval tactician nor an expert in colours.
Blue sky and black sky I feel are more like doctrines in response to the situation than actual fleets. when you are the stronger side the black sky or decisive battle doctrine is the favorable choice because it is efficient - try to fight big key battle where you slaughter the enemy with few losses. but what if you are not bigger beast, then you are going to want to try and make use of any tricks possible to provide your smaller fleet with a force multiplier. thus the blue sky strategy would be used

I'm also very curious to know more about the logistics system. After all, amateurs study tactics, professionals study logistics...
I feel like there is still much more to say about the Red Sky Doctrine as an alternative to the Blue and Black Sky Doctrines.
