能成功吗？美国海军“向锈迹宣战”

Core Viewpoint - The U.S. Navy is planning to address the long-ignored issue of rust on its ships, which has been a significant concern for years, particularly highlighted by Senator John Fehrenbach during a Senate hearing [1][3]. Group 1: Current Situation - The rust issue has been described as a more pressing threat than adversaries like China and Russia, with previous reports indicating severe conditions on various vessels [3]. - Mark Ratner, the Director of Ship Integrity and Performance Engineering, acknowledged that the Navy has known how to address the rust problem but has chosen to delay action due to other pressing issues [3][4]. Group 2: Proposed Solutions - Ratner suggested simple solutions such as using polysiloxane coatings, which are durable and easy to clean, and installing proper drainage systems to divert water away from the hull [4]. - The Navy is also considering using pre-mixed paint to reduce the workload on crew members and is emphasizing the need for proper rust removal before repainting [4][6]. Group 3: Implementation and Training - A new assessment program has been developed, allowing commanders to quantify the condition of their ships using a mobile application, which provides a more accurate reflection of the ship's status [6][7]. - Training programs for crew members are being implemented to ensure effective and efficient painting methods, with contractor support for more complex tasks [9]. Group 4: Challenges Ahead - Ratner acknowledged that even with the proposed solutions, the Navy may not achieve the pristine appearance of commercial vessels, as military ships do not have the same maintenance schedules and pressures as commercial cruise ships [10].
