I don't know if it's an issue specific to Trinity or is inherent to the current strat system.
I was attacking the Bish strat center (near A224). Before I released my bombs I checked status on clipboard, all factories at 100%. No damage was visible from air either.
I dropped a few bombs on ammo & troop factories and fuel refinery each. Clipboard showed between 10 and 25% damage to the three targets.
Less than 20 minutes later (I had covered just about 2 sectors on my way home) I noticed refinery and troop factory being fully up already. Only the ord factory's damage was staying up long as expected (~45mins)
