日本目前以傳統柴電潛艦為主力,海上自衛隊擁有如大鯨級等標準排水量約3000噸的潛艦。
日本防衛大臣小泉進次郎11日在記者會上表示,日本在修訂3份安全保障文件時,潛艦動力選項「不排除任何選項」,核動力潛艦也未被排除,但目前尚未決定是否持有。
小泉被問及核動力潛艦議題時表示,這類潛艦具有長時間潛航、長距離部署及較高水下速度等優勢。不過,他也指出,核動力潛艦涉及高昂成本、較大的艦體,以及核能相關專業人才與技術等問題,聲學隱蔽性也需要考量。
軍聞網站《Army Recognition》報導指出,日本海上自衛隊目前以傳統柴電潛艦為主力,包括配備鋰電池的大鯨級潛艦,標準排水量約3000噸。柴電潛艦仍須使用柴油發電機替電池充電,過程通常需要使用通氣管,可能增加被反潛兵力發現的風險。
長時間潛航成優勢 核能技術與配套待解
相較之下,核動力推進可讓潛艦長時間維持水下航行與較高速度,並提高遠距離海域的持續部署能力,這也是日本防衛相此次說明核動力潛艦優勢時所提到的重點。
不過,若要發展核動力潛艦,日本仍將面臨龐大的配套問題,包括核反應爐技術、港口與工業設施、專業人員培訓、輻射安全程序及相關法規監管。未來若推進,也可能牽涉與其他國家的技術合作。
這項討論也讓澳洲透過「澳英美三方安全夥伴關係」(AUKUS)發展核動力潛艦的案例受到關注。不過,日本並未參與AUKUS的核潛艦計畫,若未來推進相關方向,仍須另外處理技術與同盟合作等問題。
小泉進次郎強調,日本政府目前並未決定是否持有核動力潛艦,也沒有預設結論;政府將把各種可能性一併納入修訂安全保障文件的整體討論中。

Russia's state nuclear energy chief accused Ukraine of attacking diesel fuel trucks near the Zaporizhzhia nuclear plant, killing two Russian servicemen and risking safety.

Russia's Ural Vehicle Manufacturing Plant delivered T-90M and T-72B3M combat vehicles to the Russian army. It used new and upgraded dual-track methods to supplement frontline armor losses, and strengthened protection and anti-drone capabilities based on Ukrainian battlefield experience.

Lockheed Martin released a very short mysterious video on the social platform, showing the outline of a black aircraft with the text "Unlock the next level, stay tuned for more content." After comparison, the aviation media "The Aviationist" pointed out that the silhouette closely matches the collaborative combat aircraft Vectis developed by Skunk Works, indicating that the project may have new progress. Lockheed Martin unveiled Vectis for the first time in September 2025. It is positioned as a level 5 large-scale unmanned aerial system of the US military. It can cooperate with fifth-generation and next-generation manned fighters. It aims to make its first flight in 2027. It is powered by Williams International FJ44-4 turbofan engine.

The domestically built submarine Haikun is expected to be delivered this year, and subsequent ships will be built in a "2+3+2" model. The National Defense and Security Group, a Taiwanese think tank, recommends that follow-up ships should have submarine-launched missile capabilities to enhance combat capabilities. However, Ji Dongyun, chairman of the Taiwan Security Development Association, pointed out that the current Stegoryus-class submarines can only launch Harpoon anti-ship missiles. If they want to launch submarine-launched cruise missiles, the Chinese Academy of Sciences currently does not have this capability, unless the United States technology Technology transfer, otherwise Taiwan will not be able to achieve it within 10 years, or it may even take 20 years. Because this is an offensive weapon, it needs to be developed by itself first. Currently, Japan and South Korea do not have this capability in the Dosan class. However, South Korea's KSS-3 submarine has added a vertical launch system and self-developed cruise missiles, which may be a reference for Taiwan.

Bulgarian authorities are investigating a fire at an EMCO weapons storage facility near Tsareva Livada. Interior Minister Ivan Demerdzhiev stated that sabotage is being considered, noting potential links to a similar incident in August and other historical fires.

Unverified social media images show a new variant of China's Type 19 amphibious combat vehicle featuring a turret-mounted laser weapon, potentially designed to counter drone swarms during amphibious operations.
