Minor update.  Fighter repair in mothership hanger appears to be working for ships.  Were I was having an issue was PDC hanger, I haven't revisited this specific scenario though.

Figured out the PDC issue.  PDC's aren't allowed to have engineering spaces.  Without those you can't have any maintenance supplies available for damage control repairs.  Having Damage Control and/or maintenance storage bays are ignored.

Could be - I pretty much always have some engineering section on all ftrs - never use Damage control sections though

What were you repairing and how much maint did you have left on the MS - I have used this successfully in my immediately previous campaign after I had left some fighters unassigned too long and they suffered maint failures in orbit of the homeworld, which were then repaired aboard the Fighter barges (Carriers with no engines) which I have orbiting major planets.  I also did something similar with combat damage with one of my Carrier groups.

I'm fairly sure this was 5.20 - definitely no earlier than 5.04.  Unfortunately  this was the interesting campaign that went "futt.." due to DB corruption just after I posted an unbelievably large system (1.5LY IIRC) in the forums so I cant verify the version

Edit - jusr checked that post - it was 15 LY (eek!)

Scrapping is supposed to be in v5.3. 

Repairs are supposed to function in v5.2 when the fighter is in a hanger and the mothership has supplies, excepting armor.  I've yet to fiture out how.

Use the Damage Control tab on the Individual Unit Details window for the fighter that you wish to repair - if its docked it will take the required maint from the mothership (if avalaible) if not, or there are insufficient supplies on the mothership it will use its own maint supplies (if any).

the latest version of Aurora (5.20) allows you to scrap fighters.

Fighter can not be overhauled.

Fighter can not have repairs done to their hull armour.

With Fighter you need to keep them in hanger at all times, so the clock does not increase.

I do not think their is a way to scrap fighters, so I destroy them and salvage them.

My fighters have maintenance clocks that are getting up there in years. I've tried to overhaul them, but it doesn't seem to work. Does the maintenance clock affect fighters? Can I reset their clocks at all, or do I just need to build replacement fighters?
