Phil H. Listemann - USN Aircraft 1922-1962: Type designation letter ’A’ Part Two

NOTAM:

This study was undertaken using the available movement cards of each USN aircraft in service between 1922 and 1962.
These cards may occasionally contain errors which could lead to some disparities or omissions when the text below is compared
with official or non-official publications already published.
Alphabetical order has been chosen to structure the book (except sometimes for prototype), rather than the chronological
order of introduction into USN/USMC/USCG service.
Unless otherwise noted, the photographs come from the USN or from sources such as the National Archives or National
Museum of Naval Aviation.

Over forty years, between 1922 and 1962, the USN and USMC used a designation system which began with biplanes and ended with jets, having been used through two major wars, WW2 and the Korean War. This system remained largely the same during that time, though it evolved with the introduction of new types and technology, and new exceptions developed as well. The purpose of this series is to explain this system using photographs.

On 18 September 1962, a new system was introduced that was common to the three air arms (USAF, Army and USN/USMC) and which is still in force today. The application of this Tri-service system was effective immediately for aircraft pending delivery to the USN, but took a couple of weeks to be implemented fully in the case of aircraft already accepted, especially for aircraft based overseas or cruising on aircraft carriers.

The designation system was based on:

1 - A type designation which describes the basic mission of the aircraft.

2 - A letter designating the manufacturer (but not necessarily the designer) following the type designation.

3 - A configuration sequence indicating minor change to the aircraft type, the initial model being designated 1.

4 - Manufacturer type sequence.

5 - Status prefix. Only two letters were assigned, X - Experimental - and Y - Service test - from 1951 onwards.

6 - Special Purpose Suffix which indicates an aircraft used in a special configuration.

Samples :

AD-6 : Douglas First Attack type, sixth model.

F2A-1 : Brewster Second Fighter type, initial model.

A3D-2P : Douglas Third Attack type, second model, reconnaissance version.

PB4Y-1 : Consolidated Fourth Patrol Bomber type, initial model.
