美军增调F-35 为何紧盯台海投射

Group 1 - The U.S. military is enhancing its deployment of F-35 fighter jets in Japan, specifically at the Misawa Air Base, which is a key military outpost for projecting air power in the region [1] - The U.S. has announced plans to modernize tactical aircraft in Japan as early as 2024, with the Pentagon already deploying F-35B and F-35C variants at the Iwakuni Marine Corps Air Station and rotating F-35A jets at the Kadena Air Base [1][3] - This series of actions is viewed as a significant move to accelerate the upgrade of aircraft along the "First Island Chain" and strengthen operational capabilities in the Western Pacific [3] Group 2 - The selection of Misawa Air Base for the deployment is attributed to its strategic geographical location near the Sea of Japan, facilitating rapid entry into relevant airspace [3] - The base serves as a joint facility for the U.S. Air Force, Navy, and Japan Self-Defense Forces, enhancing the capability for covert joint operations [3][4] - The F-35 series includes three variants: F-35A for the Air Force, F-35B for short takeoff and vertical landing, and F-35C for carrier operations, collectively increasing the U.S. military's strike capabilities in maritime operations [4] Group 3 - The strengthening of U.S. air power in Japan aligns with broader strategic planning, including the Air Force's "Expeditionary Wing 2.0" initiative aimed at enhancing rapid deployment and global power projection capabilities [6] - The upgrade of air power in Japan coincides with the upcoming 2026 National Defense Strategy report, both aimed at enhancing deterrence along the "First Island Chain" [6] - Future U.S. air deployments in Japan may require Japan to provide more dispersed bases and stronger logistical support, while both nations will enhance intelligence sharing and joint training [6] Group 4 - The focus on enhancing operational capabilities in the Pacific region emphasizes two key areas: aircraft and missiles, with a shift towards stealth fighter jets replacing older models [8] - The U.S. is also improving its conventional missile capabilities, equipping the Army and Marine Corps with longer-range missiles, which poses a greater threat to regional security [8] - In sensitive situations, the U.S. may prioritize the use of intermediate-range or hypersonic missiles, necessitating vigilance and strong countermeasures [8]
