The US navy isn't everywhere all the time. Unless there were USN ships in the northern Red Sea at the time, they wouldn't have seen anything. Even if they were there & saw something, they wouldn't necessarily know what it signified. F-15s over the Red Sea? Could be Saudi. F-16s? Could be Egyptian. Tankers? Could be Saudi, could be someone's military transports.
The aircraft wouldn't have identified themselves.
