1. Unmanned aircraft is a kind of unmanned aircraft controlled mainly by radio or its own program.Its successful development and battlefield application have opened a new chapter of "non-contact warfare", which is dominated by long-distance attack intelligent weapons and information weapons.
2. Compared with manned aircraft, it has the advantages of small size, low cost, easy to use, low requirements on the operational environment, strong battlefield survivability and so on, so it is favored by the armies of all countries in the world.In several local wars, unmanned aircraft has played a significant role with its accurate, efficient and convenient reconnaissance, jamming, deception, search, calibrated shooting and in irregular conditions of operations and other combat capabilities, and triggered an endless series of military academic, equipment technology and other related issues research.
It will, together with Arsenal ships, unmanned tanks, robot soldiers, computer virus weapons, space-based weapons, laser weapons and so on, become an important role on the stage of land, sea, air and air warfare in the 21st century, and have a far-reaching impact on the military struggle in the future.
3. Some experts predict: "The future air war will be the battle between the unmanned aircraft with stealth characteristics and the anti-aircraft weapons."However, due to the unmanned aircraft is still a new thing in the field of military research, the actual combat experience is limited, the technology is not perfect, so its combat application is only limited to the high-altitude electronic and photographic reconnaissance and other limited technologies, did not fully play the huge battlefield influence and combat effectiveness.Therefore, the world's major military countries are stepping up the development of unmanned aircraft.According to the actual combat test and the needs of future operations, unmanned aircraft will be developed in more aspects faster.
