《国家利益网》2015年2月5日刊文称，美国海军一名高级官员本周三宣布，美国海军下一代空中优势战斗机（F/A-XX）不会采用高超的“速度”设计或使用太多的隐身技术。该官员还透露，不再依赖隐身技术和速度优势的F/A-XX项目将采用可以压制敌方防空系统的“武器”频谱技术。
文章称，上述言论来自格林纳特在华盛顿特区举行的美国海军未来科技博览会期间发表的演说。《华盛顿观察报》援引格林纳特的话说，“F/A-XX将不再追求速度优势，因为飞机再快也逃不过高速飞行的导弹。再高超的技术也不可能做到完全隐形，运动的物体总要留下一个特征痕迹。”他还补充说:“也许我们高估了隐身技术的作用…。如果一种东西快速通过空气，就会扰乱空气分子的正常运动，并释放热量——不管引擎的冷却系统如何高效——它总会被检测到。”
文章认为，格林纳特对飞机速度和隐身技术优势的担忧似乎很有道理。美国海军协会（USNI）网站也指出，通过扩大高速防空武器的规模，美国的潜在对手极有可能抵消美战机的速度优势。此外，隐身技术也是一种递耗资产，戴夫·马宗达最近就在《国家利益网》做了如下解释:

“俄罗斯和中国正在研究新的防空系统网络，主要采用可在超高频和VHF波段工作的雷达，它们可以让美国在第五代战斗机的大规模投资贬值。因为隐形飞机只是用来优化，应对工作在高频Ku，X，C和一部分S波段雷达探测的”。
文章也指出，美国下一代战斗机将主要针对敌人的防空系统。毕竟，美国海军已经开始使用波音EA-18G“咆哮者”和一款F/A-18F超级大黄蜂的电子战机执行任务，而F/A-XX将最终取代其中一种飞机。
不过，文章认为，格林纳特关于隐形和高速技术的看法，会让美国军队和纳税人失望。美国花了几十年时间、数千亿美元开发和部署具有速度优势的战机；F-22猛禽和F-35 联合攻击战斗机（JSF）的高效性都高度依赖隐身技术。作为美国未来战斗机部队的中坚力量，如果这两种五代机变得不足以满足美国的安全需求，美国军方可能会出现明显的战斗机缺口。
所以，尽管F-35JSF还没有服役，美国军方已经在尝试开发下一代验证机。不过，不幸的是，这些六代战斗机形成战斗力可能要等到2035年。

US Navy's 6th Generation Fighter Jets Will Be Slow and Unstealthy
Zachary Keck
February 5, 2015
The U.S. Navy’s next generation air superiority fighter will not be “super-duper fast” or employ much in the way of stealth, a senior navy official announced on Wednesday.
Chief of Naval Operations Adm. Jonathan Greenert, the Navy’s top officer, divulged some details about the Navy’s so-called Next Generation Air Dominance F/A-XX fighter jet during a speech at an industry conference.
“I don’t see that it’s going to be super-duper fast, because you can’t outrun missiles.” Greenert said, the Washington Examiner reported. “And you can’t become so stealthy that you become invisible — you are going to generate a signature of some sort,” he also noted, adding “You know that stealth may be overrated….
If something moves fast through the air and disrupts molecules in the air and puts out heat – I don’t care how cool the engine can be – it’s going to be detectable.”
In lieu of stealth and speed, Greenert said that the F/A-XX would gain access by deploying “a spectrum of weapons” that could suppress enemy air defenses.
Greenert made the remarks while speaking at the Naval Future Force Science and Technology Expo in Washington, DC.
His concerns about speed and stealth appear to be valid. As USNI News notes, the proliferation of high-speed anti-air weapons to America’s potential adversaries greatly reduces the value of speed. Stealth also is a wasting asset, as Dave Majumdar recently explained on The National Interest:
“Russia and China are already working on new networked air defenses coupled with new radars operating in the UHF and VHF-bands that threaten to neutralize America’s massive investment in fifth-generation fighters. Fighter-sized stealth aircraft are only optimized to perform against high-frequency fire control band radars operating in the Ku, X, C and portions of the S-band.”
That the next generation fighter will gain access primarily by suppressing enemy air defenses also isn’t entirely surprising. After all, the Navy already employs the Boeing EA-18G Growler, an electronic warfare variant of the the F/A-18F Super Hornet, one of the planes that the F/A-XX will eventually replace.
Still, Greenert’s claims about the declining value of stealth and speed pose some stark questions for the armed forces and American taxpayers.
The U.S. has spent decades and hundreds of billions of dollars developing and fielding the “super-duper fast” F-22 Raptor and the F-35 Joint Strike Fighter, both of which rely on stealth to be effective.
These fifth generation aircraft are expected to be the foundation of the U.S. fighter fleet for years to come. If their capabilities quickly become inadequate to meet America’s security needs, the U.S. could find itself facing a glaring fighter gap.
It’s little wonder then that the military is already fast at work trying to develop the next generation X-plane even though the F-35 JSF is not even operational yet. Unfortunately, these sixth generation fighters might not operational until 2035.
