有选择地对在役的武器装备进行现代化改装 ,依靠武器装备的改进提高武器系统的性能 ,是一条行之有效 ,多快好省地发展武器装备的途径。它不但十分有利于提高武器系统的效能 ,而且研制周期短 ,研制费用低 ,改装可降低成本 ,提高效费比和经济效益。有选择地对在役的武器装备进行现代化改装 ,已深受各国的重视并被普遍采用 ,现代化改装在美国武器装备发展中的地位正日趋重要。另外 ,还研究了对在役武器装备进行现代化改装的选择原则和改装重点以及如何从国情出发 ,进行有选择的装备现代化改装 It is an effective and efficient way to develop weapons and equipment quickly, economically and economically by selectively replacing the existing military equipment with modern ones and relying on the improvement of weaponry and equipment to enhance the performance of the weapon system. It is not only very conducive to improving the effectiveness of weapon systems, but also short development cycle, low development costs, modification can reduce costs and improve cost-effectiveness and economic benefits. The selective modernization of the weapons and equipment in service has won the attention of all countries and is widely adopted. The role of modern modification in the development of U.S. weapons and equipment is becoming increasingly important. In addition, the selection principle and modification emphasis of modernizing in-service weapons and equipment as well as how to proceed with the modernization of equipment based on their national conditions have also been studied
