〔記者吳哲宇/綜合報導〕美國海軍持續推動新一代空對空及艦載防空飛彈研發,國防新創「大熊座」(Ursa Major)公司5日宣布,獲得總價值1.37億美元(約新台幣43.9億元)的兩份合約,負責研發「緊湊型空對空飛彈」(CAAM)及「海軍模組化飛彈」(NMM)的固體火箭發動機。兩款武器分別瞄準提升匿蹤戰機內部載彈量,以及強化軍艦防空攔截能力,其中NMM更被規劃為未來取代「標準」(Standard Missile)系列的武器。
軍聞網站「Defence Blog」報導,這兩份合約分別為9100萬美元(約新台幣29.2億)的CAAM發動機研發,以及4600萬美元(約新台幣14.7億)的NMM中程型發動機研發,相關經費由美國戰爭部次長辦公室提供。「大熊座」將運用積層製造技術,加快新型固體火箭發動機研發及量產準備。

其中,CAAM是美國海軍今年8月首次公開的新型短程空對空飛彈,主要用於近距離空戰,並特別針對匿蹤戰機及未來艦載無人機的內部武器艙設計,希望在有限空間內增加飛彈搭載數量,提升空戰持續交戰能力。
「大熊座」將為CAAM研發直徑約178公厘的發動機,與AIM-120中程空對空飛彈直徑相同。新發動機採用「高裝填密度藥柱」技術,能在相同體積內容納更多推進劑,提升飛彈可用推進能量。
另一款NMM中程型飛彈則使用直徑約254公厘的發動機,最大特色是採用四聯裝配置,能在單一艦載垂直發射單元內搭載4枚飛彈,類似現役「進化型海麻雀飛彈」(ESSM)的配置方式,可提高軍艦有限發射空間的彈藥搭載量。美國海軍希望NMM於2032會計年度達成完整作戰能力,逐步取代現有「標準」系列飛彈。
值得注意的是,「大熊座」利用工業級3D列印生產大部分發動機零組件,希望降低製造複雜度並提高產量。過去美國固體火箭發動機供應主要集中於諾斯洛普格魯曼及L3Harris兩家公司,隨著防空攔截彈及長程飛彈需求增加,美國國防部正積極扶植新供應商。
「大熊座」固體飛彈系統部門總裁梅瑞迪斯(Jason Meredith)表示,目前飛彈計畫最大的瓶頸是生產能力,公司希望透過新型製造技術,加快發動機設計、測試及資格驗證,並在完成認證後迅速擴大量產,以滿足美軍未來空戰及艦隊防空需求。

Reuters reported that a fishing vessel identified as a Chinese maritime militia vessel was operating together with two Chinese vessels in the Pacific Ocean east of Taiwan in August, marking the first time such a vessel was spotted in the waters. Experts analyzed that the ship may carry out surveillance, intelligence collection or undersea infrastructure reconnaissance missions. Taiwan officials pointed out that its activities were close to adjacent areas. The United States criticized China's destructive behavior, and the Chinese Ministry of Foreign Affairs said its actions were legitimate and legal. As the frequency of China's activities in Taitung waters increases, analysts believe that Beijing is expanding its presence and strengthening its maritime rights claims through the coordinated operation of coast guard, scientific research ships and maritime militia ships.

A U.S. Marine Corps MV-22B Osprey tilt-rotor aircraft caught fire after a hard landing during a training mission near Bladen Lake State Forest in North Carolina. The four Marines on board were sent to the hospital for evaluation. At least one of them suffered burns. The cause of the accident is still under investigation.

The Chinese-made submarine prototype Haikun (SS-711) will begin a deep-water submersible test in the deep sea waters around Taiwan in late October. This is the last hurdle before delivery. The test will verify the submarine's ability to adapt to high-pressure and low-temperature environments at a water depth of more than 100 meters. If successful, it is expected to be delivered to the Navy before the end of the year.

At the AUSA Annual Meeting in Washington, defence contractors highlighted advances in air and missile defence systems amid ongoing conflicts in Ukraine and the Middle East, with Lockheed Martin showcasing ER GMLRS and PrSM missiles launched from HIMARS platforms.

The press conference of the 16th China International Aerospace Expo was held in Beijing. A number of central enterprises demonstrated the latest independent innovation results in aerospace and defense science and technology. The number of exhibiting products increased significantly compared with the previous session, covering aerospace, aviation, electronic information and other fields.

After National Day, my country's first homemade submarine, Haikun, conducted its 24th sea test and 18th submarine test. Ji Dongyun, chairman of the Taiwan Security Development Association, distributed Q-version Haikun dolls and keychains at the scene, hoping to call on more people to support the Haikun ship and the navy, and emphasized that without a submarine, it is only half a navy.
