美国海军公布下一代攻击核潜艇SSN(X)设想 定位无人潜航器母舰 目标2026年底前获里程碑A授权
美国海军 11 月 12 日在弗吉尼亚州阿灵顿举行的海军潜艇联盟会议上公布下一代攻击核潜艇 SSN(X) 的设想，该艇将作为可释放、回收并控制多艘无人潜航器的母舰。
海军水下作战部门主任、海军少将 Andrew Miller 提出 SSN(X) 的五项优先事项：更高的侧翼速度与战术控制速度、更高的在航可用性、更强的杀伤力、更优的隐蔽性与生存能力，以及对水下机器人系统的综合指挥控制。
按海军公布的进度，该项目已于 2025 年 11 月完成备选方案分析，于 2026 年 3 月获需求批准，目标是在 2026 年底前获得里程碑 A 授权，首艇采购计划在 2040 年代初。
SSN(X) 为弗吉尼亚级攻击核潜艇的后继型号，设计将采用更宽的艇体，并整合专用无人系统收放、充电与指挥控制设施。
国会预算办公室的测算以水下排水量 10100 吨、每艘 87 亿美元（按 2024 财年美元计）为假设，海军自身的估算为每艘 71 亿美元。
U.S. Navy Outlines SSN(X) Attack Submarine as Unmanned Vehicle Mothership, Targeting Milestone A Authorization by End of 2026
The U.S. Navy outlined plans on November 12 at the Naval Submarine League conference in Arlington, Virginia, for its next-generation SSN(X) nuclear-powered attack submarine to operate as a mothership capable of launching, recovering and controlling multiple unmanned underwater vehicles.
Rear Adm. Andrew Miller, Director of the Undersea Warfare Division, identified five priorities for the SSN(X): higher flank and tactical control speeds, improved operational availability, increased lethality, superior stealth and survivability, and integrated command and control for robotic underwater vehicles.
The Navy completed its analysis of alternatives in November 2025 and secured requirements approval in March 2026. It is targeting Milestone A authorization by the end of 2026, with initial procurement of the first submarine planned for the early 2040s.
The SSN(X) is the successor to the Virginia class. Its wider hull will integrate dedicated autonomous vehicle handling, recharging and command-and-control infrastructure.
Congressional Budget Office calculations assume 10,100 tons of submerged displacement and $8.7 billion per submarine in fiscal 2024 dollars, against the Navy's estimate of $7.1 billion.
