由于地缘政治的改变,以及本国国内政治、经济现状等原因,各国都加快了国防现代化的进程。战斗机在此进程中被摆在了高度优先的地位。在东欧、亚洲和南美,世界各战斗机制造公司都在为赢得数额巨大的新式多用途战斗机订单而进行着激烈地竞争。估计今年全球总共将会签订200架战斗机的合同订单。 Due to the changes in geopolitical conditions and the domestic political and economic conditions in their own countries, all countries have accelerated the process of national defense modernization. Fighters have been given a high priority in this process. In Eastern Europe, Asia and South America, fighter-manufacturing companies around the world are fiercely competing to win huge amounts of new multi-purpose fighter orders. It is estimated that this year the world will be signed a total of 200 fighter contract orders.
