V-22「魚鷹」拚服役2055年 美軍增14家供應商換新齒輪解墜機危機

Quick Look

美軍V-22「魚鷹」傾斜旋翼機近年發生多起致命墜機事故,齒輪箱故障影響機隊妥善率。為確保該機型服役至2055年,海軍V-22聯合計畫辦公室與貝爾波音擴大供應鏈,新增14家合作廠商,並加速零組件可靠性改善及機隊現代化,預計2029年完成齒輪箱全面升級。

Why It Matters

V-22魚鷹是美軍主要的垂直起降運輸機,結合直升機與固定翼優勢,但自2022年以來發生多起齒輪箱相關墜機事故,造成人員傷亡並影響作戰準備。

〔記者吳哲宇/綜合報導〕美軍V-22「魚鷹」(Osprey)傾斜旋翼機近年接連發生致命墜機事故,齒輪箱故障及飛行限制也嚴重影響機隊妥善率。為確保這款軍機能持續服役至2055年以後,美國海軍V-22聯合計畫辦公室(PMA-275)與製造商貝爾波音(Bell Boeing)正擴大供應鏈,最新宣布新增14家合作廠商,並加速推動零組件可靠性改善及機隊現代化。

軍聞網站「Defence Blog」報導,V-22辦公室近期與貝爾波音舉辦「魚鷹團隊工作小組」會議,吸引來自6個盟國、7個美國政府機構,以及超過35家國防與製造企業、約200名代表參與,討論如何改善零件供應、強化組件可靠性及提升機隊後勤維持能力。不過,美軍並未公布新增供應商名單及參與會議的盟國。

請繼續往下閱讀...

V-22計畫經理赫斯特上校(Robert Hurst)表示,透過協調全球供應鏈並導入新技術,可提高飛行線上的零件供應能力,確保部署部隊在高威脅環境下,仍能維持快速運輸及後勤調度彈性。

V-22最大特色是結合直升機垂直起降與固定翼飛機高速巡航能力,能將兩側旋翼向前傾轉,獲得優於傳統直升機的速度及航程。美國海軍陸戰隊使用MV-22執行兵力及物資運輸,美國空軍CV-22則負責特種部隊滲透與撤離,海軍CMV-22則執行航空母艦人員及補給運輸任務,並已全面接替今年退役的C-2「灰狗」運輸機。

不過,V-22長期受到傳動系統問題困擾,自2022年以來發生4起墜機事故,造成20名美軍官兵喪生,部分事故與螺旋槳旋翼齒輪箱故障,以及離合器突然重新接合的「硬離合器接合」現象有關。

其中,2023年11月一架CV-22在日本外海墜毀,造成8人死亡,導致美軍所有V-22機隊全面停飛,直到2024年3月才逐步恢復飛行,但仍受到航程及其他操作限制,影響實際部署能力。

為解決相關問題,美軍已從2026年1月開始接收重新設計的齒輪箱,採用強度更高的三次熔煉鋼材零組件,目前每月約交付12組。根據海軍陸戰隊航空計畫,預估2027年12月可恢復不受限制的機隊作戰運用。

至於全面完成齒輪箱升級,美國海軍及空軍預計2029年達成,海軍陸戰隊則需等到2033年。美軍希望透過擴充供應商及改善關鍵零件壽命,降低長期維修負擔,確保V-22未來數十年仍能維持遠征運輸與特種作戰能力。

Surprised to see Communist J-10 fighter jets appear at Taitung Zhihang Base on National Day? The truth exposure network was dumbfounded

When the supervision unit of the Ministry of Transportation and Communications was making a map of controlled road sections in Taitung for the National Day fireworks, it mistakenly planted a picture of the People's Liberation Army's J-10 fighter jet downloaded from the Internet above the Zhihang Base. Netizens pointed out that its obvious canard characteristics were inconsistent with the Chinese military fighter plane. The supervision unit admitted that it had mistakenly planted the picture and had removed the picture. The Zhihang Base pointed out that the J-10 could not fly to the base intact.

The cost of Haimabus can be significantly reduced, and the US military's low-cost "Blackbeard" is planned to be put on the vehicle

The U.S. defense start-up company Castelion released photos of the ground launch of the "Blackbeard" hypersonic missile it is developing, showing that the weapon may be integrated into the M142 HIMARS system in the future, with a range of nearly 800 kilometers. It will enhance the ability of the existing rocket artillery force to strike long-distance high-value targets. However, it has not yet been confirmed that it can be successfully launched from a standard HIMARS launcher, and it is still in the research and development stage.

The number of Taiwanese military volunteers who have retired early has soared. Young people would rather lose money than work for "Taiwan independence"

A report from Taiwan’s legislative body shows that the number of veterans receiving compensation for volunteer service in Taiwan’s military has increased from 40 in 2018 to 846 in 2025, an increase of more than 20 times in seven years. Reasons include frequent military exercises, equipment updates and increased load, relaxed admission standards leading to incompatibility, unreasonable treatment and poor manpower allocation, as well as the DPP authorities distorting military values ​​and coercing officers and soldiers to fight for "Taiwan independence." Taiwan's low birthrate and manpower shortage problems have intensified, and the voluntary service ratio is only 76.62%. Although the defense budget has increased, there is a lack of personnel to operate and maintain advanced weapons, forming a vicious cycle.
