In this episode of Deterrence Down Under, Carl Rhodes and Christine Leah examine one of the most debated developments in modern nuclear strategy: the United States' Sea-Launched Cruise Missile-Nuclear (SLCM-N) program. As geopolitical competition intensifies in the Indo-Pacific, policymakers and defense planners are reassessing how nuclear and conventional capabilities contribute to deterrence, assurance, and regional stability.

Carl and Christine break down what SLCM-N is, why the United States is pursuing the capability, and how it fits into the broader framework of extended nuclear deterrence. They explore the historical role of sea-launched nuclear weapons, the legacy of the nuclear Tomahawk missile, and the strategic arguments both for and against deploying nuclear-armed cruise missiles aboard naval platforms.
