China has reportedly developed a new type of nuclear-powered torpedo with a range of nearly 10,000 kilometers. This torpedo, equipped with conventional or nuclear warheads, can launch from Shanghai and potentially reach San Francisco directly. The low cost and long range of this weapon make it a significant development for China's defense capabilities. Nuclear torpedoes, with their immense power and lethality, have attracted global attention and are considered a crucial component of national defense strategies. While the United States and Russia have been active in nuclear torpedo research, China's progress in this field has been slower. However, recent reports suggest that China's nuclear torpedoes have made significant advancements. The development of these weapons raises questions about their power and their potential role in future conflicts.
