A Lockheed F-80 Shooting Star of the USAF Acrojets demonstration team sports the buzz number FT-507 (Bill Larkins)

If you’ve ever looked at pictures of post-WWII US Air Force aircraft, you probably noticed a series of very large letters and numbers painted on the sides of the fuselage. They’re pretty hard to miss. With the military’s penchant for stenciling serial numbers on everything from nuclear bombers to hats, these numbers actually do identify the aircraft, but there was a specific reason those highly visible ID numbers came into use.

P-51D Mustangs of the 20th Fighter Group in 1946. In this case, the F in the buzz number refers to “photograph,” as these were reconnaissance Mustangs. The F for reconnaissance was discontinued in 1948 and only used for fighters. (US Air Force)

When WWII ended in Europe in May 1945, the United States Army Air Forces had a half-million men and about 17,000 aircraft stationed in Europe. Those numbers fell quickly as forces were removed from the theater, but there were still many high performance aircraft with no missions to carry out, and thousands of bored pilots who had put their life on the line in the high-stakes atmosphere of aerial combat. With no enemy to fight, pilots of the Eighth Air Force took to buzzing the countryside for excitement, performing low-level flights over houses and farms and air bases in the finest barnstorming tradition.

Not even lowly cargo planes were safe from buzz numbers. Here, a C-82 Packet is branded with CQ-978. (Bill Larkins)

The USAAF wasn’t too keen on the practice, so they developed the Buzz Number system so spotters could identify pilots in the hopes of discouraging the practice. Alphanumeric codes were painted in the largest type possible on US aircraft, numbers that could easily be read from the ground and would identify the offending aircraft and pilot.

An F-84E Thunderjet from the 9th Fighter-Bomber Squadron takes off for a mission in Korea. The A in the buzz number indicates that FS-424 was already taken. This aircraft was shot down by flak on 29 August 1952. (US Air Force)

Using a system that was somewhat similar to the US Navy’s aircraft designation system, the first letter of the buzz number identified the aircraft’s mission: A for attack, B for bomber, C for cargo, F for fighter (or P, as earlier fighters were called categorized as pursuit), and so on. The second letter identified the specific type of aircraft, while the numbers represented the last three digits of the aircraft’s serial number. If two aircraft happened to have the same buzz number, the letter A was added after a hyphen.

F-86 Sabre 52-4666, with the buzz number FU-666 (Tim Shaffer)

For example, this restored F-86 Sabre with the serial number 52-4666 has been given the buzz number !!!error: Indecipherable SUB-paragraph formatting!!! . F for fighter, U for North American F-86, and 666 for the last three digits of the serial number. And, in a bit of added serial number trivia, the first two digits of an Air Force serial number will tell you the year the aircraft was manufactured. So, our Sabre example was built in 1952.

Even experimental aircraft didn’t escape buzz numbers. Here, the Republic XF-84H Thunderscreech gate guard is emblazoned with its own identifying buzz number. Note that it carries the same FS prefix as its F-84 Thunderjet ancestor. (Bill Larkins)

Buzz numbers were a regular sight on most US Air Force aircraft throughout the 1950s, but they were eventually phased out by the mid-1960s. Technical Order 1-1-4 in 1965 did away with the requirement for buzz numbers, and they were soon removed or painted over. A full list of buzz numbers can be found !!!error: Indecipherable SUB-paragraph formatting!!! .

The ultimate buzz number? The number FX-936 on the starboard engine of this Lockheed YF-12 may be the very last appearance of a buzz number, on one of the fastest aircraft in the Air Force inventory. (US Air Force)

Cracks me up to put a buzz number on anything that flies as high as an A-12.

Wonder what it’d be like to have your house buzzed by the YF-12.

I remember reading about this aircraft or a similar one where these hyper propellers generated super-sonic sound waves that nauseated the pilots. And other people. I guess that was a problem.

I really could have done with a bit of sun that day. Shots still came out nice, though. And that silver sword almost looks better in that light.

It could also be heard from miles away, hence the name Thunderscreech.

Shots came out very nice. No glare to contend with, that’s got to count for something. :)

Thanks. It’s always a trade off of some sort. Also , there is no photography without regret.

Yeah, I member that, now that you mention it. I watched a show about the launch of the B-58 Hustler. That was a cool aeroplane. My favorites always seem to have propellers, though, unless they are large: A-1, C-130, KC-135, B-52 or both, in the case of the B-52.

I know you dig the Orion, so check out this video. Great stuff.
