Are the AI stations immune to blade attacks?

...shall I never return to see a flak turret again.

EDIT:  ...and vampires and/or command station under attack notifications.

i thought flak turrets had an aoe effect? (meaning ignores shields)

[Spikey00]

That's what I thought too; I guess not.

 I don't know how the secondary shots work, but the primary shot has a terrible hit %. Select a flak turret and hover over targets to see it for yourself!

 In my tests, in the best scenarios (lots of enemy ships with low health and shields, snake map with only one incoming wormhole covered by lots of tractors), a cap of flak turrets did similar damage as a cap of lightnings. For a lot less energy, so they are really good in ideal situations. However in all non ideal situations they performed rather poorly.

 They do cost little knowledge and mostly use metal rather than crystals thought.

(Just try clicking on one of these bloody things without pausing the game when they're all over your structures!)

I have not tried using HBCs player-side as of yet, though I understand there are good things to come from that when I have knowledge to spare from my offensive might.

I have found that flak turrets actually work far far better when combined with gravity turrets.  I had a few vampires (3-4) attacking the command station of one of my back water systems, so I sent some engineers, and insta-built a set of five flak turrets.  Around 30 seconds later the vampires were still at pretty high health, and showing no signs of dying before the command station.  So I thought "well, it looks like the flak is missing the vampires, lets slow them down" so I built a grav turret, and Presto! The vampires were all dead in around 5 seconds.  This happened a few other times too, so I'm pretty sure it's consistent.

While grav turrets effecting the hit effectiveness of flak turrets might be a bug, it is currently happening, so I would just add in grav turrets with flak, and you will have no problems with melee ships.

it might be that the vampires just took more time to hit the command station each pass - thus making them regenerate health slower. A valid tactic certainly..
