预警机的研制是一项庞大而复杂的系统工程,涉及到众多技术门类和专业领域,研制难度极大。我国曾于上世纪70年代在前苏联图-4轰炸机的基础上研制了空警1号预警机,但由于性能无法满足我军要求而没有服役。现在我国已成功研制了空警2000、空警200等型预警机,大大提高了我国的空防水平,对维护我国国家安全具有重要作用。 Early warning aircraft development is a large and complex system engineering, involves many technical fields and fields of expertise, the development of extremely difficult. In the 1970s, our country developed the AWACS-1 AWACS on the basis of the former Soviet Union Figure-4 bomber. However, it failed to serve because of its inability to meet the requirements of our military. At present, China has successfully developed the early-warning aircraft such as the air-marshals 2000 and the air marshals 200, which have greatly raised the level of air defense in our country and played an important role in safeguarding our national security.
