World War II was the most prolific period of American military flight jacket development in history. The rapid expansion of the Army Air Forces, the diverse operational environments of a truly global war, and the pace of aviation technology advancement all drove the creation of multiple jacket designs in the span of just a few years. Understanding each model — what it was for, who wore it, and what distinguished it — gives you a complete picture of American military aviation history through one of its most defining garments.
A-1 (1927): The First Standardized Army Flight Jacket
The A-1 was the first standardized leather flight jacket issued by the U.S. Army Air Corps, appearing in 1927. A front-zip leather jacket with a shirt collar, it established the basic template of the military leather jacket. The A-1 was replaced by the A-2 in 1931, which refined and improved the design significantly.
A-2 (1931): The Officers' Standard
The A-2 became the standard leather flight jacket for Army Air Corps and Army Air Forces officers from 1931 until its discontinuation in 1943. Horsehide or cowhide construction, snap-down collar, knit wool cuffs and waistband, bi-swing back, and slash front pockets. The A-2 was worn by fighter pilots, bomber pilots flying at lower altitudes, and aviation officers generally. It was revived by the U.S. Air Force in the 1980s and is currently in use.
B-3 (1934): High-Altitude Shearling Jacket
The B-3 sheepskin jacket was specified for high-altitude bomber crews facing temperatures between -40°F and -60°F in unpressurized cabins. Full shearling construction, fold-up collar, belted cuffs and waist. Worn by crews of B-17, B-24, and B-29 bombers throughout WWII. Discontinued after the war as aircraft became pressurized. Now reproduced by Cockpit USA in its original specification, available at Legendary USA.
M-422A and G-1 (1940s): The Navy's Leather Heritage
The Navy developed its own series of leather flight jackets distinct from the Army Air Forces designs. The M-422A was an early Navy jacket with a mouton fur collar — the distinctive feature that would define the G-1. The G-1, formally specified in the 1940s, became the standard Navy and Marine Corps aviator leather jacket and has been in continuous service ever since. Unlike Army jackets, the G-1 has never been replaced for naval aviation use.
B-10 (1943): The Transitional Jacket
The B-10 appeared as a transitional design in 1943 when the Army Air Forces began moving away from leather to nylon. The B-10 used a nylon shell with a knit collar — not as clean a look as the A-2, not as warm as the B-3, but lighter and cheaper to produce than either. It bridged the gap between the leather era and the full nylon jacket that followed.
B-15 (1943-1944): The First Nylon Flight Jacket
The B-15 was introduced in 1944 as the first primarily nylon U.S. military flight jacket. It featured a nylon shell, knit collar and cuffs, a synthetic fill for insulation, and a zip front with a snap wind flap. The B-15 replaced the leather A-2 for production purposes, though leather jackets remained in use from existing stock through the end of the war.
The ANJ-3 and Naval Specialization
The Navy maintained its preference for leather jackets throughout WWII while the Army Air Forces shifted to nylon. The ANJ-3 and related designations covered various Navy leather jacket specifications during the war, all sharing the mouton collar and leather shell characteristics that defined naval aviation outerwear. The G-1 designation consolidated these into a single standard that persists today.

Frequently Asked Questions
How many different flight jacket models did the US military use in WWII?
The U.S. military used more than a dozen distinct flight jacket models during WWII, covering Army Air Forces leather and nylon designs plus Navy-specific models. The most significant are the A-2, B-3, G-1, B-10, B-15, and associated naval specifications.
Which WWII flight jacket is the rarest today?
Original A-2 jackets with decorated nose art and squadron patches are the rarest and most valuable original WWII flight jackets. Undecorated original B-3 jackets in good condition are also uncommon.
What was the last leather flight jacket the Army Air Forces used in WWII?
The A-2 was officially discontinued in 1943, making it the last leather jacket in Army Air Forces production during WWII. However, existing stocks continued to be worn through the end of the war.
Did Navy pilots wear the same jackets as Army Air Forces pilots?
No. The Navy maintained its own distinct leather jacket specifications (M-422A, G-1) with the signature mouton fur collar, while the Army Air Forces used the A-2 and B-3.
