Interception aircraft risk return fire from the UFOs they are attacking. If hit, they will sustain system and structural damage and require repair before being sent out again. This is the first step that a craft will go through upon returning to base and is the only one that is skipped if not needed (if the craft is undamaged).
All craft repair at a rate of one point of damage per hour, straight up(XX:00) spent in "Repairs" status. This converts to the following percentages of repair rates per full day spent in Repairs.
|Craft||Repair % per day|
