A little more than a century ago, the US Army Air Service came up with a scheme for naming the military’s multiplying fleet of airplanes.
The 1924 aircraft designation code produced memorable names like the B-17, A-26, B-29, and P-51—B for bomber, A for attack, and P for pursuit—during World War II. The military later changed the prefix for pursuit aircraft to F for fighter, leading to recognizable modern names like the F-15 and F-16.
Now, the newest branch of the military is carving its own path with a new document outlining how the Space Force, which can trace its lineage back to the Army Air Service, will name and designate its “weapon systems” on the ground and in orbit. Ars obtained a copy of the document, first written in 2023 and amended in 2024.
Drawn by local talent, cheap labor and state cash incentives, start-ups building the weapons of the future are revitalizing manufacturing in once-vibrant industrial towns.
