Nit: although the 'pedia says rear admiral outranks commodore, in the U.S. Navy the rank is equivalent to commodore in other navies.

Thats because the US Navy has two rear admiral ranks. The lower rear admiral is a 1 star officer and is equivalent to commodores in other navys. The upper rear admiral is a 2 star officer is equivalent to "normal" rear admirals in most other navies.
