F22因供氧系统故障全面停飞,求证消息的可靠性

BREAKING: USAF orders F-22 fleet stand-down

Got a tip today that all F-22s have been parked. Air Combat Command confirmed a few minutes ago, and our news article is posted here and is excerpted below.

Oxygen system concerns prompt F-22 stand-down
By Stephen Trimble

The US Air Force has stopped flying all Lockheed Martin F-22s for an indefinite period over concerns about a possible glitch in the onboard oxygen generation system.

The stand-down order issued on 3 May by Air Combat Command (ACC) chief Gen Will Fraser comes about six weeks after the F-22s were restricted to flying below 25,000ft due to the same problem. [Read more...]

Dave Majumder at Defense News broke the story about the F-22 OBOGS concerns back in March. Read his article here.

Stay tuned. Air Combat Command should be releasing more information shortly.

UPDATE: ACC has just sent me written answers to my questions about the stand-down order. Read them on the jump.


Air Combat Command replies:

What prompted the stand-down?
The stand-down was prompted by recent reports of potential oxygen system malfunctions.

Is this related to the OBOGS investigation?  If so, why did you tighten the flight restrictions from a 25,000 foot limit to a stand-down?

Yes, it is. Initiating a temporary stand-down in response to recent incidents minimizes further risk to aircrew until we can resolve the issue.


What is the nature of these recent incidents?

Increased frequency of pilot reported physiological incidents such as hypoxia and decompression sickness.


How does this impact F-22 training and operational readiness and training?  Are Air Sovereignty Alert (ASA) missions still being flown?  

The temporary stand-down will have a negligible effect on real-world missions such as ASA, as the F-22 remains available for National Security directed missions.  Additionally, MAJCOM commanders may allow one-time flights if warranted and prudent.  One example might be simple repositioning flights to move F-22s to home stations.  Crews will maintain proficiency through simulator and ground training events.

F22已经正式服役很长时间了,现在又出这种状况,不知道这个消息是否可靠,但是也说明了一个飞机确实是个复杂的系统工程,每一点小错误都会带来严重的

想起了当年F15当机库皇后的日子。不过这种问题应当很快解决。
另外就算是没有22,美国空军依然是这个星球上近乎于变态的强大力量。仍然是无敌的。

作为有人驾驶的最终一代作战飞机-F22一定有许多磨合不成功之处,但无论如何,它毕竟代表了一种标准、标尺,其他国家的下一代飞机就是以此作为超越的目标。
        目前因为美军不会轻易把F22用于一般的战事,更不会出口到自己的盟国,从这一点看来,美军对它也不是完全放心,必定有一些外人所不知的问题。如果说只是为了技术保密,不让中国获取尖端科技的机密,美军完全不用这么大张旗鼓的掩盖,吹嘘为保护技术领先地位。F15、F16已经面世几十年了,中国到底窃取了多少机密呢?不还是从SU27之后才取得技术上的飞跃。因此,捂得严实,防备中国之说,是没有根据的。
         如果F22真的是完美无缺才令人怀疑,毕竟集成了当今电子、电磁、空气动力、材料等学科最新技术的产品,会没有一点问题,是令人难以信服的。就像隐藏、吹嘘了许多年的F117一样,作为第一代隐形飞机,一定有它的弱点,只是在南斯拉夫打下它之前,人们不知道而已。别人不知道是因为他们没有接触F117,没有使用它们的经验,只是从一次战例中知道了它的弱点。作为美军,作为F22的订购者、生产者、使用者、维护者,他们比世人更清楚知道自己飞机的优缺点,有他们主动爆出一些无关作战的小问题,反而会令人信服,有一种残缺之美,否则就完美的近乎神话了。
        总之,F22作为美国独家享用的最尖端产品,一定会有大家说不知道的问题,与其让世人无端猜疑,不如自己主动爆一些无关紧要的小毛病,从而混淆视听,掩盖其真正的问题。扰乱潜在对手探求遏制战法的思路。

完美无缺只是科技人员追求的目标,不可能实现。

确实停了。这么牛的项目还是有很多问题啊,而且基本上都是些比较小儿科的问题,可能是美国人太过关注飞机的隐身啊,超音速巡航啊,这些技术性能了,最基本得供养出来问题,以前还出现过电脑程序错误这类事。虽然F-22是世界上唯一现役的五代机,但是它从立项到90年试飞,05年服役,这经历了很长时间,它的一些电子设备是当时的佼佼者,但是比起现在的还是略显不足啊。不管怎么说F-22是当今唯一现役的五代机,其优势还是相当的明显,当然没有那款飞机是完美无缺的,多多少少会出现这样那样的问题,科技毕竟是在进步的嘛!

飞机作为高科技产品,太复杂了,任何小问题都可能导致停飞,摔机的后果谁也伤不起
