On November 10th, the next generation bomber B-21 "Raider" of the US Air Force took off from the US Air Force's 42nd factory in Palmdale, California and landed at nearby Edwards Air Force Base, completing its maiden flight. On November 18th, the French Ministry of Defense issued a statement announcing the test launch of an M51.3 submarine based strategic ballistic missile at Lande in southwestern France. On November 29th, the Russian Navy launched the Arkhangelsk nuclear submarine, which is Russia's fifth Yassen class nuclear submarine. These actions by the United States, France, and Russia are the latest developments in the intense competition among relevant countries in the nuclear field. In recent years, relevant countries have attached increasing importance to the status and role of nuclear weapons, considering them as the core means of determining the battlefield process and influencing the decision-making of opponents. In order to better enhance the effectiveness of nuclear deterrence and enhance nuclear readiness, relevant countries have upgraded their nuclear arsenal, conducted nuclear exercises, developed new nuclear vehicles, and even withdrawn from nuclear arms control treaties. All of these have increased the risk of nuclear war and conflict, seriously impacting the global strategic stability situation. The US nuclear submarine "Connecticut". In order to maintain its hegemonic position, the United States has been vigorously promoting its nuclear modernization plan and continuously improving the practical performance of nuclear weapons. On October 28th, the US Department of Defense announced the modernization upgrade plan for the B61 nuclear warhead. The upgraded nuclear warhead is named B61-13 to replace some of the active B61-7 warheads. This type of nuclear warhead can be dropped by various fighter jets and bombers such as F-15, F-16, F-35, B-2, etc., and the explosive yield can be adjusted as needed, with a minimum yield of 300 tons of TNT. The new nuclear warhead can be used to attack the underground reinforced nuclear command and control facilities of opponent countries, and the United States is attempting to use it to launch a preemptive nuclear strike. On October 12th, the Strategic Situation Committee of the United States Congress issued a report calling for the United States to further expand its nuclear arsenal, including the production of more stealth strategic bombers and strategic nuclear submarines, and enhance nuclear deterrence by enhancing the survivability and concealment of nuclear forces. Due to a certain gap in conventional military strength compared to the United States, Russia has placed more emphasis on developing nuclear forces. On October 5th, Russian President Putin announced at the annual meeting of the Valdai International Debate Club that Russia has successfully tested a Haiyan nuclear powered cruise missile. According to media reports, the "Haiyan" missile adopts a nuclear power device, can carry nuclear warheads, has unlimited range and ultra-low altitude flight capability. Similar to the Haiyan, there is also the Poseidon nuclear torpedo. On January 16th of this year, Russian media reported that Russia had produced the first batch of "Poseidon" nuclear torpedoes, which were more than 100 times more powerful than the atomic bombs dropped on Hiroshima that year. These torpedoes were about to be deployed on the strategic nuclear submarine "Belgorod". In addition to its high explosive yield, the Poseidon nuclear torpedo also has characteristics such as ultra long range, ultra-high speed, and high concealment. As the only nuclear power of the European Union and a permanent member of the Security Council
