I have seen phased array aircraft radars that look as if they still
mechanically sweep the dish. I thought the entire reason for phased arrays was
so they wouldn't need to mechanically move. I know how phased arrays work in
principle, but that's as far as I go. What am I missing here?

The new Sampson phased array on the UK's Type 45 is a rotating 2-faced
array - think it rotates at around 60 rpm.
