For aerospace, U of Alabama Huntsville should be on your list.
With your stats, you would receive a 45% merit discount on tuition, which would reduce the OOS cost of attendance from around 34K to around 24K. https://www.uah.edu/admissions/undergraduate/financial-aid/scholarships/freshmen/freshmen-non-al-merit-tuition-scholarships (You can also get more scholarship $ by retaking the SAT/ACT before May 1st)
UAH is particularly known for aerospace; Huntsville is a hub of the aerospace industry, with many opportunities for UAH students. https://www.ozy.com/acumen/the-new-age-of-aerospace-is-in-huntsville-alabama/83661/
Admissions are rolling; you can still apply.
I do agree that you would probably know by now if an ROTC scholarship were going to happen.
