A rear-admiral is a flag officer, the naval equivalent of a general officer. A rear-admiral is senior to a commodore and brigadier-general, and junior to a vice-admiral and lieutenant-general.
The rank of admiral (or full admiral, or four-star admiral) is the highest rank normally achievable in the U.S. Navy. It ranks above vice admiral (three-star admiral) and below fleet admiral (five-star admiral). There have been 262 four-star admirals in the history of the U.S. Navy. Of these, 221 achieved that rank while on active duty, 40 were promoted upon retirement in recognition of combat citations, and one was promoted posthumously.
