Commander Air Group

The Commander, Air Group, or CAG when used in conversation or for shorthand, is the most senior officer of all squadrons aboard a starship. Despite most Starfleet ships operating primarily in space, the name is derived from a title used during Earth's second world war aboard Aircraft Carriers. 
=== Responsibilities ===
The CAG is responsible for the upkeep and operation of all craft and pilots, and is typically placed in direct command of up to a full Wing of craft. The CAG of a starship can range in rank from Lieutenant to full Commander, and reports directly to that ship's Commanding Officer. For Stations or other stationary assets, the CAG will typically possess the rank of Commander or Captain, and will typically report either directly to the station's Commanding Officer or the Admiral in command of the sector.. In all cases, the CAG is considered one of the fast tracks to starship command, second only to the position of Executive Officer. 
==== Examples of Use ====
CAG positions are increasingly rare across Starfleet, as more and more ships possess smaller auxiliary craft complements. Only larger ships like the Galaxy, Odyssey, Solbianca, and Jupiter classes will possess enough ships to have need of a CAG. The only current use of CAG officers within the 22nd Mobile is on Starbase 220 and the USS Adagio.
