What is casu f 14 det a us navy in world war 2?

Combat Air Service Unit 14, Detachment A. The Navy loved initials and acronyms, which in this case was confusing. There were CASUs, and CASU-Fs. A CASU was a Carrier Air Service Unit, but the addition of the "-F" to the designation meant a Combat Air Service Unit. Both types of units did the same type of work to the same aircraft, but I believe a CASU-F was intended for deployment to a shore-based naval airfield or air station in a combat zone. There was a CASU-F group number 14, according to the document linked below under "related links", but where it was deployed I do not find. A carrier aircraft service unit or a combat air service unit was a group of Navy officers and enlisted men who were assigned to a Naval air station or airfield. They comprise aviation machinist mates, ordnancemen, metal smiths, electricians, hospital corpsmen, cooks,bakers and seamen. They were not assigned to a sqaudron. The squadrons came to them. They are usually fighter, scout bomber or torpedo squadrons. Thus, the name carrier aircraft service unit, (as these were the three types of Navy carrier airplanes of WWII), or combat air service unit, where these planes are in action.
