A USN aviation wing is designated as either carrier air, maritime patrol & reconnaissance, strategic communications, training air, or type (there are type wings for strike fighters, electronic warfare, airborne early warning and logistics, maritime strike helicopter, and sea combat helicopters that provide squadrons to the carrier air wing for operations, as well as shore based fleet logistics support and tactical support wings that operate independently of aircraft carriers). All of these entities maintain administrative and standardization control and are OF 5 (US pay grade O-6) captain commands roughly analogous to a USMC Marine Aircraft Group or USAF wing. Officers in command of wing level units other than carrier air wings utilize the legacy title of "commodore" and are authorized to fly a command broad pennant from their headquarters ashore or when embarked aboard a warship as the senior officer present afloat (SOPA).
