MA-1 bomber jacket


The MA-1 bomber jacket (also known as the MA-1 flight jacket) is an American military jacket which was first developed in the mid 1950s. The MA-1 and its predecessor, the B-15 flight jacket, were originally developed and needed at that time because the emergence of the Jet Age created new requirements for pilot performance, safety, and comfort.

Prior to the invention of jet aircraft, fleece-lined leather jackets were issued to flight personnel. However, the new jets could fly at much higher altitudes and in much colder temperatures than propeller aircraft. If the heavy, bulky leather jackets became wet from rain (when the pilot walked to his aircraft) or from perspiration, the water would freeze at high altitudes, making the jackets cold and uncomfortable. Also, the new jets were more streamlined in design. Cockpits were cramped and filled with new equipment. Speedy, unimpeded access to and exit from cockpits became even more critical for safety. Rather than bulky leather, a sleek, lightweight yet warm jacket was needed for the new jet technology.

To meet these needs, a new type of flight jacket was developed from the existing B-15 jacket, which was initially produced in cotton, but later produced in the same pattern but in high quality nylon. The B-15 had a wool collar with pile (a little like fur) carried over from the earlier B-10 that was found to interfere with straps in practice. Nylon had been discovered prior to World War II but it was not used in flight clothing until after the war, possibly because the demand for nylon for items such as parachutes consumed the available supply during the war.

The first MA-1 jackets were issued around 1949 or 1950 to United States Air Force and Navy pilots and flight crews. Small numbers were also issued to Army flight personnel. MA-1 jackets first appeared in Europe in very small quantities in the mid-to-late 1950s probably on the black market and at sales of government surplus. In the early to mid-1960s more MA-1 jackets appeared in Europe as Alpha Industries and later Rothco began to export MA-1 jackets and other military clothing to European Air Forces and commercial customers.

The MA-1 was designed by the United States Air Force to serve as an intermediate weight flight jacket for use all year. This was accomplished by manufacturing the MA-1 from very high quality nylon fabrics and polyester interlinings. The lightweight nylon design allowed the pilot to wear the jacket open and be comfortable in warm weather. Upon entering the aircraft, the pilot could zip the jacket closed and be afforded ample protection against the cold conditions encountered in flight.
