In recent years, North Korea has continued to advance its naval modernization, with a key focus on developing a new class of nuclear-powered submarines and their associated nuclear propulsion systems. Although technical details remain scarce, official North Korean media have released images and reports indicating the development of a so-called ‘tactical nuclear attack submarine,’ claiming successful creation of a compact, ship-mounted nuclear reactor. Analysts suggest Pyongyang may be drawing on early Soviet or Chinese approaches, attempting to adapt land-based small modular reactors for submarine use. However, building a reliable naval nuclear propulsion system involves overcoming significant engineering challenges, including reactor miniaturization, radiation shielding, long-term operational stability, and effective cooling mechanisms. To date, there is no conclusive evidence that North Korea has mastered a fully functional naval nuclear reactor, nor that any of its submarines possess genuine underwater nuclear propulsion capability. The international community remains deeply concerned that if Pyongyang succeeds in fielding nuclear-powered submarines, it would significantly enhance its second-strike nuclear capability, posing a new challenge to regional security. This development continues to draw close scrutiny from global intelligence agencies and defense experts.
朝鲜近年来持续推进其海军现代化，其中一项关键举措是发展新型核潜艇及其配套的核动力系统。尽管外界对其技术细节了解有限，但根据朝鲜官方媒体发布的图像和报道，该国正在研发一种被称为‘战术核攻击潜艇’的新型舰艇，并宣称已成功研制小型化船用核反应堆。分析人士指出，朝鲜可能借鉴了早期苏联或中国的技术路径，尝试将陆基小型核反应堆改装为适用于潜艇的动力装置。然而，要实现真正可靠的舰载核动力系统，需解决反应堆小型化、辐射屏蔽、长期运行稳定性以及冷却系统等复杂工程难题。目前尚无确凿证据表明朝鲜已掌握完整的舰用核反应堆技术，更未证实其潜艇具备实际水下核推进能力。国际社会普遍担忧，若朝鲜成功部署核动力潜艇，将大幅提升其二次核打击能力，对地区安全格局构成新的挑战。因此，这一动向持续受到各国情报机构与防务专家的高度关注。
