有與其他國家不太一樣嗎？
美國 B-2 也沒好到哪。
還是你把美國也算成共產國家？
Why The B-2 Bomber Can Not Fly In Rain?

引用:
When it rains, the $2 billion stealth bomber B2 Spirit can't go for missions, but why? According to a 1997 analysis by the General Accountability Office, the B2 bomber can only be flown in or exposed to extremely favorable conditions, such as pleasant temperatures, low levels of humidity, and a lack of rain. A combination material used to build the skin of the B2 bomber absorbs radar signals; this makes the plane very hard for enemy radar to detect, but the same RAM, or radar-absorbing material, that covers its body fails when exposed to the presence of water; thus, that's the reason. A gallon of RAM paint may cost you $5,000. Bombers are more likely to be detected by radar if they are exposed to weather conditions that can penetrate their skin and weaken the material, so what the hell this B-2 doing in the rain at all? Bad weather may wreak havoc on the B2 bomber's engines as well. They lost $2 billion the last time they let a B-2 bomber remain uncovered in the rain. Rain can speed up the process of cooling, damaging the engines that are meant to work at extreme temperatures. In a year of testing that started in March 1997, the B-2 bombers could only complete their assigned tasks 26% of the time. The B2 skin's weakness was a major factor in the failures in our study.

為什麼 B-2 轟炸機不能在雨中飛行？
下雨時，價值 20 億美元的 B-2「幽靈」隱形轟炸機無法執行任務，這是為什麼？根據美國政府問責局 1997 年的分析報告，B-2 轟炸機只能在極其有利的條件下飛行或暴露，例如宜人的溫度、低濕度和無雨。 B-2 轟炸機蒙皮所採用的複合材料能夠吸收雷達訊號，這使得敵方雷達很難偵測到它。然而，這種用於覆蓋機身的雷達吸波材料（RAM）一旦遇水就會失效，這就是原因所在。一加侖的吸波塗料可能高達 5000 美元。如果轟炸機暴露在可能穿透蒙皮並削弱材料的惡劣天氣條件下，就更容易被雷達偵測到，那麼這架 B-2 轟炸機究竟為什麼要在雨中飛行呢？惡劣天氣也可能對 B-2 轟炸機的引擎造成嚴重損壞。上次讓一架 B-2 轟炸機在雨中暴露，他們損失了 20 億美元。雨水會加速冷卻過程，從而損壞那些設計用於在極端溫度下工作的引擎。在 1997 年 3 月開始的為期一年的測試中，B-2 轟炸機完成預定任務的機率僅為 26%。 B-2 機身蒙皮的薄弱是導致我們研究中故障的主要原因。
