The MA-1, a modified version of its predecessor, the B-15 flight jacket, is mainly used in the intermediate zone, and is said to have been officially adopted in the mid-1950s, after the end of World War II. Within the broad category of flight jackets, jackets are classified according to the climate of the area in which they are used and the purpose for which they are used. Heavy Zone, -50 to -30°C, and Very Heavy Zone. Flight jackets are now generally made of sage green nylon, but until the 1940s, during World War II, cotton and leather were the most common fabrics.

In 1947, the U.S. Army Air Force was disbanded and the U.S. Air Force was officially established. As flight altitude increased, condensation on flight jackets caused water to freeze, which interfered with in-flight activities. Since then, the MA-1 has been used continuously through the Vietnam War until the 1990s, and "Alpha Industries" handled most of its production, expanding its scope to town use in the 1970s and beyond, The company started as a subcontract factory for John Ownbey, a major contractor of the MA-1 and M-65 field jacket in 1959, and quickly became the largest manufacturer of these jackets with the introduction of the MA-1.

Alpha Industries" was established in 1959, when the company was involved in the production of flight jackets from the time of its predecessor "Dobbs Industries," and also developed subcontract manufacturing for John Ownbay, as mentioned above. Since the U.S. Department of Defense commissioned the company to review military jackets, it has grown to become one of the largest contractors in the industry.

The military standard numbers (Mil-Spec) for MA-1s are divided into eight major categories. In other words, even in the MA-1 category, there are various models for each era. The first model, MIL-J-8279, was issued to combat units on a priority basis when it was first developed, and was used continuously until the early 1960s.

In 1961, the Kennedy administration sent a limited number of military advisors to support the South Vietnamese military, which triggered a surge of activity in the U.S. munitions industry. In the midst of the Vietnam War, which also intensified, Alfa Industries entered the industry in earnest, and the factory's utilization rate rose sharply, with the number of employees growing rapidly from 100 to more than 500. It is said that it was around this time that the MA-1 was issued to all pilots on land, sea, and air, and that the supply system was finally in place, although priority was initially given to combat units.

In 1963, the lining, which had been sage green, was changed to bright Indian orange, the international rescue color, to increase visibility to rescue teams in the event of an unforeseen incident involving a passenger. It became reversible. The mil-spec is MIL-J-8279D, and it is one of the models called "mid-term type" in the vintage scene.

In the 1970s, the Vietnam War, which had become a quagmire, finally came to an end, and veterans who had completed their military service were allowed to bring back the flight jackets they had worn when they left the war zone. This gave the flight jacket a new level of civilian status. The MA-1, which was sold to the general market as a so-called "military surplus," was prized for its high functionality as a warm-weather outerwear for town use and spread to many countries. The Skins, who were active in the British youth culture from the end of the 1960s to the beginning of the 1970s, wore the MA-1 with Getagrip 10-holes, vintage H-sus, and Ben Sherman's B.D. shirts as their uniform. The unique style became the uniform. In the "Oi!" scene, which was established in the 1970s as a subgenre of punk rock, the MA-1 also played a uniform role as a symbol of the working class.

This is the last model with wool pile lining. The lining gradually shifted to polyester material around this time. Flaps were adopted for the front handwarmer pockets, and the military specs also changed to MIL-J8279E. In 1973, aramid fiber with excellent flame resistance was developed, and the CWU-45P, the successor to the MA-1, was introduced. However, it is said that the MA-1 was only issued to pilots during the first phase of the war, and test pilots and ground crews continued to wear the MA-1.

In the 1980s, the decision to greatly expand the size and budget of the Pentagon under the Reagan administration led to a sharp increase in demand from the Department of Defense. The new demand created a new demand, and by the mid-1980s, $1.8 billion had been spent on clothing alone. And at the same time, "Alpha Industries" was transforming from a business for the U.S. military to a military-based global brand for the general public.

Furthermore, the commercial business took off, and "Alpha Industries" became a huge garment brand representing not only the military but also the United States. By this time, the MA-1 had easily surpassed the category of flight jackets, and was now being discussed in the context of casual and daily wear. In Japan, the release of the movie "Top Gun" rekindled the popularity of flight jackets. In Japan, the release of the movie "Top Gun" triggered a resurgence in the popularity of flight jackets, especially the black MA-1.

The MA-1 has given up its position to the CWU-45P, and in the U.S. Air Force, it has transitioned to the MIL-J-8279G used only by ground crews. The three-line logo, familiar since the 1960s, has been replaced by a new logo with initials.

With the collapse of the Soviet Union and the virtual end of the long-running Cold War, pacifism in the U.S. accelerated, and the distribution of the budget to society and the private sector, rather than defense, became the current banner. The military industry quickly stagnated and many related companies closed their doors, but Alpha Industries was able to survive because of its foresight in turning its attention to the consumer business from the 1970s. In particular, the 1990s was the era of street fashion. Many foreign street brands such as Stussy, as well as domestic brands commonly referred to as "Urahara," developed many custom models based on the MA-1 made by Alpha Industries.

On the other hand, by collaborating with various companies and events in the U.S., it also established its position as a staff jacket and advertising jacket. It is said that it was around this time that minor changes were made to the design for town use.

In 1994, the U.S. Minister of Defense served as the point of contact and supplied the Israeli Air Force with the commonly known Israeli MA-1, which was adopted not for practical use but for ceremonial purposes, such as attendance at a military service, with new evolettes on the shoulders.

The 2000s were a time of great challenges for Alfa Industries, which was approaching its 50th anniversary. after 911 and the Iraq War, the U.S. military budget was focused on electronics and technology, and the prehistoric wars that sent soldiers into the battlefield came to an end. The prehistoric wars of sending soldiers into battle came to an end.

Alpha Industries, which had been closely tied to the military, was also forced to change to a military-inspired brand targeting the consumer market, and it sought to strengthen its casual wear and street wear. The MA-1 Tight, a modernized version of the MA-1 with a more contemporary fit while maintaining the original functional beauty of the MA-1, is a Japan-only model that continues to be popular with both men and women alike as a hit item representing recent years.

After serving its military role, the MA-1 has been further sped up and transformed into everyday wear since the 2010s. Modern marketing has been successful, and the brand has gained support, especially from the younger generation. Here are the latest models introduced in 2018.

Looking back on the company's history from its founding to the present day, we can see that it has been honed to the strictest Mil-Spec standards in the world, that it has never been bogged down by fads or transient trends, and that it has a functional beauty backed by a solid reliability backed by its 60-year history. This is the greatest advantage of Alpha Industries.
