These are the USS Skipjack SSN-585 and USS Scorpion SSN-589 from Monogram. The  Skipjack is built out of the box (OOB) and was  made similar to the one on the box. The Scorpion was modified in the scope/mast array and its tiny limber hole lines to the rear of the sail. The the paint measure is as she wore before her tragic loss. Only the sail numbers were eventually painted over in gray.
