The military field is a relatively special application field for connectors, which not only means that the performance of connector products is more advanced and precise, but also for military competition between countries, military connectors are an important symbol of national military strength.

Military connectors are basic components necessary for the formation of a complete weapon system. Compared with commercial connectors, they are a special and sensitive type of connector with significant characteristics: strict manufacturing tolerances, solid structure, extremely high reliability, high cost and resistance to harsh environments. Connectors used in the military industry traditionally mainly include circular, rectangular, printed circuit board, RF and a small number of special connectors.

Military/aerospace applications have long been ranked fifth in the entire connector market after automotive, computer and peripherals, telecommunications and data communications and industrial applications. In the entire connector market, military/aerospace connectors account for about 7%. From 2000 to 2006, the world military connector market was divided in 2003. The market capacity of the world military connector market has been hovering around 2 billion US dollars. However, in 2004, stimulated by the Iraq War and the War on Terrorism, the world military connector market rebounded strongly, with sales soaring 17% over 2003 to 2.3292 billion US dollars. In 2005 and 2006, the market continued to grow significantly, with sales reaching 2.4499 billion and 2.6927 billion US dollars respectively. Bishop & Associates' latest forecast is that the world military connector market sales in 2007 will reach 2.8288 billion US dollars, an increase of 5.1% over 2006. The development momentum is still steady, which is rare in decades.

The new military revolution has spawned new connector technologies and performance, and has become the most important engine for the continuous development of high-tech connectors. From the early 1990s to the beginning of the new century, the United States launched four local wars under high-tech conditions. From the "electronic warfare" born in the Gulf War to the "information warfare" that emerged in the Kosovo War to the "network-centric warfare" demonstrated in the recent Iraq War, it vividly demonstrated the tremendous power of the world's new military changes. Supporting these high-tech wars are a large number of new high-performance weapons and equipment that are information-based and intelligent. Such new military equipment and facilities will inevitably put forward new or higher requirements for the performance of various components including connectors.

According to a research report by Fleck Research, a well-known American market research company, most connector manufacturers in the world report that the application in the military/aerospace field is growing, and reconnaissance aircraft, missiles and smart bombs are the main factors leading to the continued growth of connectors. In the Iraq War, laser-guided bombs and satellite-guided bombs increased by two times, replacing weapons in the Afghanistan War. General fighters are equipped with cluster bombs, free-drop bombs and laser-guided bombs, which require in-flight separation connectors, drop connectors, tower connectors, pylon connectors and interstage connectors. The demand for these connectors has rapidly risen to $206 million. If all types of connectors, such as PCB connectors and I/O connectors, are included, the global demand will reach $616 million.

The new military revolution sweeping the world is driving major countries in the world to continuously increase their basic R&D investment or direct purchase of military equipment, which will greatly promote the development of military connectors in the world.
