Windows? Reminds me of one of Quint's lines from Jaws:
"Left, port! Right, stahb'rd! Ya git it wrong, I'll throw your a$$ out the little round winder on the side!"
I believe Mike is right, they're vents. On older kits, they're often molded with way-out-of-scale grating (eg, Hasegawa Essexes)
At what stage in her career does your model depict the Midway? I've been getting nostalgic to track down the old Revell kit depicting her in her early days.
Best regards,
