F-5战斗机改装工作现状

The Status of F-5 Fighters' Upgrades

据估计,目前在全世界26个国家和地区的空军中约有1700架F-5仍在服役,另有约800架与F-5在同一种原型机上发展而成的双座型教练机在美国空军中服役。据F-5战斗机的设计和制造商诺斯罗普·格鲁门飞机公司估计,目前全世界现役的1700架F-5战斗机中约有1/2可能会进行延寿和更新改装.总的更新改装费可高达15亿美元。另外美空军800多架现役双座型教练机中的一半也要进行电子设备的现代化改装。对于飞机和机载设备制造厂商来说,这是一个很有吸引力的市场。

Now, nearly 1700 F-5 Fighters are used by about 26 countries and regions air forces in the world and almost half of these aircraft need to be upgraded. This will be a major market in future F-5 upgrade. USA' x Northrop Grumman Corp. and some others countries' companies are setting about researching a variety of concepts of upgrating F-5.
