Looking Back / Edited by Mark Albertson: Pages 694 & 695, December 1962 issue, ARMY AVIATION Magazine.

We now have a new AR which should be of interest to all Army Aviators. This new AR 700-26, dated 18 Sept. 1962, titled, “Designation, Redesignation, and Naming Military Aircraft, upersedes AR 705-42. The AR also implements DOD Directive 4506.6, dated 6 July 1962.
Here is what the AR does: It prescribes a standard designation for all aircraft and applies to all services, Army, Navy, Air Force, etc. It further reidentifies all aircraft which are in the nventory.
Hold it!
Don’t get panicky!
This reidentification is not as bad as you might think; it has many advantages.
Now all of the services will call an aircraft by a common designator.

This system will also permit the interchange of maintenance data and problem areas with our sister services without the barrier of different designators.
Typical Examples:
If you’ve read AR 700-26, you’ll find out the system works like this.
Let’s use the H-34C and the L-23D as examples:
C. Modified Mission symbol, “Cargo.”
H. Basic Mission and Type, “Helicopter.”
34. Design Number.
C. Series symbol
R. Modified Mission symbol, “Reconnaissance.”
U. Basic Mission and Type, “Utility.”
8. Design Number.
D. Series symbol.
The actual assignment of the designation will be made at the time of purchase of the aircraft, so in the field all you have to worry about is learning that designation. To help you to learn the new designators we have a chart to cross reference the old into the new. This system does not preclude you from using the “Popular Names” of aircraft, in fact it is encouraged.
