I know very little about the Navy,other than they mostly float around on boats,and will mostly disappear the first 15 minutes of any war against Russia or China.
The subs will last longer,but once they launch their missiles,their locations will be know,too. Assuming of course there is still anybody living in Russia or China to launch missiles at them.
Because of this,I see nothing wrong with having a woman being in such a senior position in the Navy,the USCG,or the USAF.
Providing,of course,that the USAF commander should ALWAYS be a veteran who flew fighters or fighter/bombers.
IMNSHO,the US Army and the USMC should ONLY have male leaders at the top who have personally fought in ground wars.
This opinion is worth every dollar you paid for it,but I do believe it to be the correct one.
