〔編譯陳成良/綜合報導〕日本首相高市早苗政府計畫在年底前修訂《國家安全保障戰略》等安全保障3文件,內部浮現將「研究持有核動力潛艦」納入文件的方案。這將觸及日本長年禁止自衛艦採用核能推進的政策,相關討論最快11月下旬進入下一階段。
共同社6日報導,高市政府為修訂安保3文件成立的專家會議中,有人主張引進核動力潛艦,也有人持審慎態度。自民黨執政盟友日本維新會則主張儘早引進,認為若要讓潛艦在水下運用艦載垂直發射系統(VLS),核能是必要的動力選項。
《讀賣新聞》報導,如果新文件寫入「檢討持有」或「研究持有」核潛艦,日本政府即可進一步展開調查研究,包括模擬運用及估算成本,但這並不代表日本已決定取得核動力潛艦。消息人士指出,一旦相關內容寫入文件,無論最終是否持有,都能更容易展開具體討論。
日本核動力潛艦仍有一道門檻
日本長期依循核能和平利用原則,不允許以核能作為自衛艦推進動力。1965年,當時科學技術廳長官曾提出自衛艦不得採用核能推進的見解,相關政策延續至今。日本同時奉行「非核三原則」,即不擁有、不製造及不引進核武器。
自民黨目前提出的建議則刻意採用「活用次世代動力」的表述,並未直接點名核能。日本維新會的主張則更為明確,認為具備水下VLS能力的潛艦需要核能動力,並要求加速引進。
核動力潛艦可長時間維持水下航行,且航速通常高於常規動力潛艦,因此支持者認為有助日本在周邊海域執行警戒監視及提升嚇阻能力。不過,核潛艦的建造成本預計將是常規動力潛艦數倍,核動力系統的維護、整備與操作也需要專業技術及人才。
日本政府專家會議最快預計11月下旬彙整報告,執政聯盟也將在此前後協調相關政策。防衛大臣小泉進次郎與官房長官木原稔此前均表示,不應排除討論持有核潛艦,但自民黨內仍有審慎意見,最終文件如何表述仍待協調。

A report from the U.S. Congressional Research Service shows that since the U.S. and Israel launched "Operation Epic Fury" against Iran on February 28, 81 U.S. military aircraft have been lost or damaged, with replacement costs estimated at $1.9 billion to $3.3 billion, with drones suffering the most heavy losses.

Ukraine's railways have kept the country running since a full-scale invasion in 2022, but Russian drone attacks have intensified, and attacks on locomotives have surged this year, with more than half of all attacks occurring this year, leading to massive delays and emergency evacuations.

A reporter from China News Service visited the Chinese Navy Type 055 destroyer Zunyi. The officers and soldiers of the ship inherit the spirit of the Long March and have experienced and grown up in practical tasks such as South Pacific drills, responding to the approach of foreign troops, and conquering deep-sea anti-submarine warfare. They go to sea for an average of more than 200 days a year and cover a range of nearly 180,000 nautical miles.

The delivery date of Taiwan's first homemade submarine, the Haikun, has attracted much attention and is still undergoing sea testing and adjustments. Expert Ji Dongyun analyzed that based on the highest principle of safety, the final stage of testing was cautious, resulting in a delay in the delivery schedule.

It is rumored that Latin American drug lords took the opportunity to send mercenaries to Ukraine to participate in the war and learn practical drone combat technology. According to statistics, there are about 6,400 Latin American volunteers serving in Ukraine, mainly Colombians, which has raised security concerns in Latin America.

German Defense Minister Pestorius announced that the Army will prepare the first dedicated drone regiment in 2027 to integrate aerial drones, ground robots, electronic warfare, anti-drone and deep strike capabilities of up to 500 kilometers, with the goal of achieving full combat capability in 2029. The new regiment will be incorporated into the 10th Armored Division and may support German troops with high combat readiness.
