Interesting. I wouldn't have thought, till now, that a GOOD QUESTION could also be a (or at least contain it's own) Good Answer.

And a GA from me, too!!

All your going to get are guesses... my guess is, some type of pressure equalizer for the Pratt & Whitney F119-PW-100 turbo fan jet engines... what ever that may mean...

Airplane whistles? That would explain the strange noises those things sometimes make. But I thought the strange noises came from the stealth models.

No they’ve found that those stealth models were so quiet, the ground crews didn’t know they were taxiing up behind them, and to avoid getting run over an engineering change notice was issued to medicate mitigate the problem...

The fix, they added these to the turbofans... problem solved.

The drawing may not have a key, but at least we know the holes belong there!

Go to a toy store, buy & build the model and you will probably get your answer.

Originally thought it was chassis wings. Then there was soap about the hanging points of the weapon. Didn't study this plane, it's hard to be specific. The extreme thought was soap about the fuel filter access doors.

They may be ports to equalize the air pressure inside of the bomb bays to prevent explosive decompression when opened,or to provide assistance with positive pressure to assist opening the bomb bay doors against the high velocity outside air.This would reduce the size and weight of the required hydraulics.
