美国军方在过去三天测试了四枚核能力导弹，就像俄罗斯总统弗拉基米尔·普京(Vladimir Putin)透露，他曾向华盛顿的同行出售先进武器一样。
在一份新闻稿中，美国海军周五表示，它“进行了四次三叉戟二号潜艇发射弹道导弹的预定导弹试验飞行”，使用俄亥俄州-级弹道导弹潜艇美国内布拉斯加号加州圣地亚哥海岸。声明称，周三发布了两次，周五又发布了两次，但“并不是为了应对任何正在发生的世界事件”。
这一消息是在普京在东部经济论坛全体会议上表示，他已于6月份通知唐纳德·特朗普总统后的第二天发布的他可以买的莫斯科即将推出的一些最先进的武器，包括核能力和高超音速导弹，目的是在军事竞争对手之间“平衡一切”。这位俄罗斯领导人随后表示，美国官员已经表示“他们将很快自己制作”，据报道，一名美国高级官员周五表达了这一立场。
“美国没有什么理由考虑从俄罗斯购买先进的导弹技术。在导弹技术的安全开发、测试和使用方面，美国比俄罗斯拥有主要的比较优势，”国营的俄罗斯新闻社援引这位未透露姓名的特朗普政府官员的话说。
三叉戟包括海运部分和大约70%的美国核三联体，其中也包括陆地和空中能力。特朗普在2017年初就职大约一年后，于去年2月公布了一份新的《核态势评估报告》，其中包括为三叉戟导弹开发低当量W76核弹头的计划，令人担忧这种修改可能会增加核冲突的可能性。
普京和他的高级官员一再向特朗普政府提出这个问题，特朗普政府指责莫斯科已经在研究这种低当量武器，但两位领导人似乎都决心以某种方式实现核武库现代化。特朗普发表核报告一个月后，普京宣布研发新的高科技武器，据称这种武器能够击败所有现代甚至未来的防御系统。
其中包括RS-28萨马特洲际弹道导弹、阿旺加尔高超音速滑翔飞行器、Kh-47M2金扎尔空射高超音速导弹、9M730布雷夫斯特尼克核动力巡航导弹和波塞冬核动力水下鱼雷无人驾驶飞机。今年早些时候，普京还透露了正在进行的测试俄罗斯高超音速潜艇发射巡航导弹3M22 Tsirkon。
普京认为，这些措施是必要的，以应对美国在2002年放弃1972年《反弹道导弹条约》和在东欧建立高科技、一度被禁止的防御系统引发的“军备竞赛”。特朗普誓言要扩大他的国家的反导弹基础设施，并于上月退出了又一项冷战时期的军备控制协议，即限制310至3420英里范围内陆基导弹的中程核力量条约。
美国辩称，俄罗斯开发了一种名为诺华9M729的巡航导弹，违反了协议，但莫斯科官员辩称，他们的五角大楼同行已经违反了规则，在罗马尼亚和波兰的国防系统中安装了同样的进攻性武器发射器。双方都否认了各自对他们的指控，在美国退出协议数周后，美国发射了一枚巡航导弹，射程超过310英里什么新闻周刊确认的是同一个发射器，尽管五角大楼说它是不同的配置。
普京周四坚称，他将遵守自己实施的暂停部署此类中程武器的禁令，但前提是特朗普不首先这样做。这位俄罗斯领导人还表示，他已经下令开发此类系统，以回应上月美国的测试。
虽然目前的导弹紧张局势主要集中在俄罗斯与美国领导的北约西方军事联盟结盟国家之间的边界，但莫斯科方面也对国防部长马克·埃斯珀(Mark Esper)表示正在考虑在亚洲部署陆基中程导弹的言论感到震惊。日本首相安倍晋三周四与普京一道表示，他没有收到美国的此类提议五年防御计划韩国上个月发布的版本不包括该平台的计划。
尽管如此，俄罗斯仍对美国不断扩大的全球军事存在表示怀疑，尤其是在长期军备控制协议崩溃之际。另一项面临风险的重大交易是限制双方允许的核武器和发射器数量的新《削减战略武器条约》。
莫斯科官员称，华盛顿方面没有回应他们关于延长将于2021年到期的条约谈判的邀请，特朗普迄今只表示有兴趣达成一项新协议，其中也包括核武器明显减少的中国。俄罗斯外交部长谢尔盖·拉夫罗夫告诉俄罗斯报纸《消息报》周三，美国和俄罗斯对这种大规模杀伤性武器负有“世界主要责任”，呼应了北京方面拒绝限制其核武器的主张。
U.S. LAUNCHES FOUR MISSILES AS IT REJECTS RUSSIA'S OFFER TO SELL ADVANCED WEAPONS
The U.S. military has tested four nuclear-capable missiles in the past three days, just as Russian President Vladimir Putin revealed he had offered to sell advanced weapons to his counterpart in Washington.
In a press release, the U.S. Navy said Friday it "conducted four scheduled missile test flights" of the Trident II submarine-launched ballistic missiles using Ohio-class ballistic missile submarine USS Nebraska off the coast of San Diego, California. Two launches occurred Wednesday and two more on Friday, but they "were not conducted in response to any ongoing world events," according to the statement.
The news came a day after Putin told a plenary session of the Eastern Economic Forum that he had informed President Donald Trump back in June that he could buy some of Moscow's upcoming, state-of-the-art weapons, including nuclear-capable and hypersonic missiles in order to "balance everything out" between the military competitors. The Russian leader then said U.S. officials have indicated "they will soon produce it themselves," a position reportedly expressed Friday by a senior U.S. official.
"There is little reason for the United States to consider the purchase of advanced missile technology from Russia. The United States has a major comparative advantage over Russia in the safe development, testing and employment of missile technology," the state-run Russian News Agency cited the unnamed Trump administration official as saying.
The Trident comprises the seaborne component and about 70 percent altogether of the U.S. nuclear triad, which also includes land and air capabilities. About a year after taking office in early 2017, Trump unveiled in February of last year a new Nuclear Posture Review that included plans to develop lower-yield W76 nuclear warheads for Trident missiles, raising concerns that such modifications could make nuclear conflict more likely.
Putin and his top officials have repeatedly raised the issue with the Trump administration, which has accused Moscow of already researching such low-yield weapons, but both leaders appear determined to modernize their arsenals in one way or another. A month after Trump's nuclear report, Putin announced the development of new, high-tech weapons said capable of defeating all modern and even prospective defense systems.
These included the RS-28 Sarmat intercontinental ballistic missile, the Avangard hypersonic glide vehicle, the Kh-47M2 Kinzhal air-launched hypersonic missile, the 9M730 Burevestnik nuclear-powered cruise and the Poseidon nuclear-powered underwater torpedo drone. Earlier this year, Putin also revealed ongoing tests of a Russian hypersonic submarine-launched cruise missile, the 3M22 Tsirkon.
Putin argued such measures were necessary in response to an "arms race" sparked by the U.S.' abandonment of the 1972 Anti-Ballistic Missile (ABM) Treaty back in 2002 and build-up of high-tech, once-banned defense systems in Eastern Europe. Trump has vowed to expand his country's anti-missile infrastructure and pulled out last month of yet another Cold War-era arms control deal, the Intermediate-Range Nuclear Forces (INF) treaty restricting ground-based missiles ranging from 310 to 3,420 miles.
The U.S. had argued Russia violated the agreement through its development of a cruise missile called the Novator 9M729, but Moscow officials argued their Pentagon counterparts were already breaking the rules by installing the same launchers used for offensive weapons in their defense systems in Romania and Poland. Both sides denied the respective claims against them and weeks after the U.S. left the deal, it fired a cruise missile traveling over 310 miles from what Newsweekconfirmed was the same launcher, though Pentagon said it was in a different configuration.
