美軍F-35A戰機內部武器艙升級:目標2030年前將攜彈量從4枚增至6枚

Quick Look

美軍推動『艙內六彈』(Six in the Bay)升級專案,計畫於2030年9月前將F-35戰機內部武器艙的空戰飛彈攜帶量從4枚增至6枚,提升50%彈藥量,同時維持低可偵測構型,具體改裝方式及適用型號尚未公開。

Why It Matters

F-35為美國主力隱形戰機,內部武器艙設計用於維持低可偵測性。現有構型限制內掛飛彈數量為4枚,為提升作戰彈藥量而不犧牲隱形性能,美軍推動艙內六彈專案。

〔編譯陳成良/綜合報導〕美軍主力匿蹤戰機F-35未來內部彈艙將能攜帶更多空戰飛彈。美國軍方最新採購評估報告披露,美軍正推動一項名為「艙內六彈」(Six in the Bay,SITB)的現代化專案,目標在維持內掛構型下,將F-35內部飛彈攜帶量由原本的4枚提升至6枚,攜彈量增加50%,預計於2030年9月達成開發目標。

據《Army Recognition》報導,這項升級計畫列於美軍「2027會計年度F-35現代化選定採購報告」中。F-35戰機為維持匿蹤性能,在執行相關作戰任務時,可將武器收納於機身內部彈艙。這次SITB專案的核心,就是在不增加外掛武器的情況下,讓戰機一次攜帶更多內掛空戰飛彈。

請繼續往下閱讀...

透過這項SITB專案,美軍希望讓F-35在不依賴機翼外掛架、維持低可偵測構型的狀態下,使內部飛彈攜帶量由4枚增加至6枚。換算之後,單架F-35可攜帶的內部空戰飛彈數量將增加50%,讓戰機在不增加外掛武器的情況下擁有更多可用彈藥。

這項設計對F-35尤其重要,因為外掛武器可能增加雷達反射特徵,而武器內掛則有助維持戰機原本的低可偵測構型。美國陸戰隊2026年航空計畫也已將「艙內六彈」列為F-35C的武器整合項目之一。

怎麼多塞2枚? 美方暫未公布改裝方式

不過,最新官方文件並未公開SITB的具體機械改裝方式,包括武器掛架如何調整、內部彈艙如何配置,以及增加的2枚飛彈將採用何種型號。文件也沒有說明這項升級究竟適用F-35A、F-35B、F-35C中的哪些型號。

外界過去曾討論以「Sidekick」武器掛架增加F-35內掛飛彈,但目前沒有足夠官方資料證實SITB就是採用這項方案。因此,現階段能確定的重點仍是「4枚增至6枚」以及2030年9月的開發目標。

「艙內六彈」並非獨立武器計畫,而是F-35整體現代化工程的一部分。美方同時推動感測器、通訊、電子戰及武器整合等能力升級,並透過Block 4及相關軟硬體更新強化戰機性能。

目前美軍公開資料確認的是SITB的攜彈量與時程,至於最終採用的內部武器配置及各型F-35的適用範圍,仍有待後續測試與認證。

Leopard 1 tank modified with Skyranger 35 air defense system has entered service in Ukraine

Germany's Rheinmetall has modified the Leopard 1 tank chassis into the Skyranger 35 short-range air defense system, which has been delivered to the 1020th Anti-Aircraft Missile Regiment of Ukraine. The system is equipped with a 35mm rotary cannon with a rate of fire of 1,000 rounds per minute and an effective range of 4,000 meters. It can use AHEAD air-blast ammunition to intercept low-altitude threats such as drones. The contract value is hundreds of millions of euros, supported by the frozen assets of Russia, and the Italian company is responsible for production and integration. The Leopard 1 tank is a veteran of the Cold War. It was first mass-produced in 1965. There are still more than 4,700 vehicles in service in nine countries.

"Foreign Affairs" published an article: Taiwan should turn to sea denial rather than fight for sea control

"Foreign Affairs" published a story about Taiwanese military expert Liao Hongxiang and former US Director of National Intelligence Dennis. Blair's joint article pointed out that the Taiwan Navy is overly dependent on large surface ships. In the face of China's improvement in surveillance, unmanned vehicles, and precision strike capabilities, it should shift to a military-building strategy centered on sea denial, emphasizing the dispersed deployment of small ships and land-based anti-ship systems to ensure that it can continue operations even if it suffers the first wave of strikes, and prevent the People's Liberation Army from free use of the Taiwan Strait.
