What is the big secret here? An aircraft carrier is a huge floating metal box housing a nuclear reactor supplying 1920’s technology steam propulsion plant with a large flat roof where planes can take off and land.
The Navy got the USS Gerald R Ford technology by data obtained from sinking the USS America a conventional. To sink the America it took a week of hits even that didn't sink her. She finally went down only after explosive charges that had previously been placed for the specific task were set off. If he obtained that data it compromised all our reserve conventional carriers in mothball and active CVN's as well.
