Abstract: In the era of global connectivity and network tools to enhance accessibility, cyber warfare has become an important part of conventional warfare, a new military field. In June 2017, the British think tank AngloAmerican Security Information Committee (BASIC) released a survey report “Hacking UK Trident, A Growing Threat”, saying that the British “Trident” nuclear submarine has serious cyber security risks and is vulnerable to catastrophic cyber attacks. According to the report, a successful cyber attack may completely offset the submarine operation instructions, causing casualties and may even cause nuclear warheads to be launched directly or indirectly. This growing threat of cyberattacks against strategic missile nuclear submarines may have a serious impact on strategic stability between countries and the second strike capability of nuclear warfare. This paper analyzes the security risks in the various stages of the Trident nuclear submarine supply chain, proposes countermeasures from the national strategic level, and guides the safety of the Trident system.
