^it might of be relevant that until very recently women were straight up not allowed to become sailors at all. Mom's lowkey salty about that because as a kid she wanted to.
While that's changed now (depending on locale obv) the military in general is still overwhelmingly a male occupation and in any case career progression takes time, doubly so in peacetime, so it'll be a long time before you start seeing meaningful numbers of women in senior posts.
And obviously they aren't going to be any younger than male colleagues advancing that far either, anyway.
