让我们把目光聚焦于中俄两国在大型运输机领域的较量。由于美国C-17系列运输机早已停产，并进入存量时代，因此这场对比中，美国暂时退出了竞争舞 台。 接下来，让我们把目光转向中国的运-20系列运输机。在运-20定型之前，解放军在执行重型装备运输任务时，只能仰赖数量有限且设计并非尽善尽美的俄制 伊尔-76。2016年，运-20大型运输机正式定型。2020年之后，中国推出了全面升级的运-20B，该机型换装了四台澎湃的涡扇-20系列发动机。 运-20B的最大起飞重量超过220吨，最大运载能力达到66吨，在各项性能指标上均优于俄罗斯最新的伊尔-76MD-90A。更为关键的是，运-20的产量远超伊 尔-76。据美国媒体报道，截至2025年，运-20系列已生产超过150架。照此推算，平均年产量至少在15-16架左右，而且考虑到产能爬坡的因素，近年来的实 际年产量肯定更高。 首先，回顾一下大型运输机领域的格局。美国的C-17曾是性能卓越的代表，其最大起飞重量超过260吨，最大运载能力高达77吨。然而，自2015年停产后， 美国现役的220余架C-17，只能算是"老骥伏枥"，难以在产量上与中俄一较高下。 反观俄罗斯，2025年交 ...

Core Insights - The recent increase in the number of domestically produced Y-20 transport aircraft has surpassed 100 units, indicating a significant enhancement in China's long-range transport capabilities [1][3] - The Y-20's early versions utilized Russian engines, and while domestic engines have been adopted, there are still challenges in achieving optimal performance for long-distance and heavy-load missions [3][5] - The current air transport system in China exhibits a "middle-heavy, two-ends-light" characteristic, with a lack of super-heavy transport aircraft capable of carrying hundreds of tons, which poses a challenge for strategic airlift capabilities [5][9] Industry Analysis - Manufacturing large aircraft is a complex and costly endeavor, with few countries capable of achieving this feat, highlighting China's rapid progress in developing the Y-20 [7] - Future competition will not only focus on the quantity of aircraft but also on factors such as the level of automation, ease of maintenance, and operational versatility of the aircraft [7] - To truly establish a strong strategic transport capability, it is essential to address the core issue of engine performance and develop larger super-heavy transport aircraft [9]
