軍事專用飛機,包括很多類型、用於執行不同專門軍事任務的特種飛機,例如,執行空中警戒和指揮引導任務的空中預警機;為作戰飛機進行空中加油的空中加油機;執行空中偵察任務的電子偵察機和照相偵察機;執行協同作戰任務的電子戰飛機。還有諸如空降機,空中救護機,雷達、武器和其它電子設備的空中試驗機等等其它軍事專用飛機,其中的很多飛機,由於需要配置複雜龐大的設備和較多操作人員,用的是大型機體的飛機。由於進行專門研製的費用很高,在國際上通常是利用現有飛機進行改裝,可以節約大量的經費開支。其中一些大型的軍事專用飛機,大多是利用干綫客機改裝而成的。例如,美國波音公司應 Military dedicated aircraft, including many types of special aircraft used to carry out different specialized military missions, for example, airborne early warning aircraft that perform airborne and command and guidance missions; aerial refueling aircraft that refuel air combat aircraft; electronic reconnaissance to carry out aerial reconnaissance missions Aircraft and photographic reconnaissance aircraft; electronic warfare aircraft performing collaborative missions. There are also other military aircraft, such as air test aircraft, air ambulances, radar, weapons and other electronic equipment, and many of these aircraft, due to the need to deploy complex equipment and more operators, using large Body of the aircraft. Owing to the high cost of specialized development, it is common in the world to retrofit existing aircraft to save a lot of financial resources. Some of these large military aircraft are mostly converted from mainline passenger aircraft. For example, the United States Boeing Company should
