To satisfy the strategic requirements of conducting both offensive and defensive operations, the Air Force attaches importance to developing new types of fighters, air and anti-missile defense weapons, and command automation systems. It has deployed some relatively advanced computerized equipment, and air-to-air and air-to-ground precision-guided munitions, upgraded the electronic information systems of the equipment on active service, and improved the basic networks for intelligence and early warning, command and control, and communications. It has in the main established a major battle weaponry and equipment system with third-generation aircraft and ground-to-air missiles as the mainstay, and modified second-generation aircraft and ground-to-air missiles as the supplement.
