1968年12月26日，我国第一艘核潜艇——091型‘长征一号’成功下水，标志着中国成为世界上第五个拥有核潜艇的国家。今年是这一重大历史事件55周年。核潜艇作为国家战略威慑力量的核心装备，其研制成功不仅打破了超级大国的核垄断，也极大提升了我国的国防实力与国际地位。在当时技术封锁、资源匮乏的艰难条件下，以彭士禄、黄旭华等为代表的科研人员隐姓埋名、自力更生，攻克了反应堆、水下导航、声呐系统等一系列关键技术，实现了从无到有的历史性跨越。‘长征一号’于1974年正式服役，开启了中国海军迈向深蓝的新篇章。55年来，我国核潜艇技术不断迭代升级，已形成完整的战略与攻击型核潜艇体系，为维护国家主权、安全和发展利益提供了坚实保障。这一成就不仅是中国科技自立自强的典范，更是民族精神与集体智慧的结晶。
On December 26, 1968, China successfully launched its first nuclear submarine—the Type 091 ‘Changzheng-1’—making it the fifth country in the world to possess such advanced naval capability. This year marks the 55th anniversary of this historic milestone. As a cornerstone of national strategic deterrence, the successful development of the nuclear submarine broke the nuclear monopoly held by superpowers and significantly enhanced China’s defense capabilities and global standing. Under extremely challenging conditions—facing technological embargoes and limited resources—scientists like Peng Shilu and Huang Xuhua worked anonymously and independently to overcome critical technical hurdles in areas such as nuclear reactors, underwater navigation, and sonar systems, achieving a historic leap from zero to one. The ‘Changzheng-1’ officially entered service in 1974, heralding a new era for the Chinese Navy’s blue-water ambitions. Over the past 55 years, China has continuously upgraded its nuclear submarine technology, establishing a comprehensive fleet of both ballistic missile and attack submarines, providing a robust foundation for safeguarding national sovereignty, security, and development interests. This achievement stands as a shining example of China’s scientific self-reliance and the collective wisdom of its people.
