Russia is in the midst of overhauling its nuclear forces, including new ICBMs, ballistic-missile submarines and modernized heavy bombers.

俄罗斯正在大幅修整其核武库, 包括开发新的洲际弹道导弹、反弹道导弹潜艇和现代化的重型轰炸机。

If not, ICBMs armed with nuclear weapons will not reach their targets.

否则，配备核武器的洲际弹道导弹将无法击中目标。

He said ICBMs cannot attack South Korea due to the limits of the missiles'firing range.

他说，由于导弹射程的限制， 洲际弹道导弹无法攻击韩国。

Russia says it has readied a new generation of ICBMs, which Associated Press correspondent Lisa Dwyer says have already been deployed.

俄罗斯表示自己已经准备好了新一代洲际弹道导弹，美联社记者丽莎·德怀尔称该导弹已被部署。

So because ICBMs travel so far and fast, everything is harder.

因此，由于洲际弹道导弹行进得又远又快，所以一切都变得更加困难。

Now the US and Russia have had ICBMs since the late 1950s, but building them is really hard.

现在美国和俄罗斯自 1950 年代末以来就拥有洲际弹道导弹，但建造它们真的很困难。

To be clear, we're pretty sure that North Korea doesn't have working thermonuclear ICBMs yet, but they might someday.

需要明确的是，我们非常确定朝鲜还没有可用的热核洲际弹道导弹， 但总有一天会的。

Experts say that, well, it doesn't seem like they've completely figured out how to make functional ICBMs; they are getting closer.

专家们说， 好吧，他们似乎还没有完全弄清楚如何制造功能性洲际弹道导弹； 他们越来越近了。

The silo-based missile capable of carrying multiple nuclear warheads is intended to replace the R-36 ICBMs that are known by the NATO reporting name of Satan.

这种能够携带多个核弹头的井基导弹旨在取代被北约称为撒旦的R-36洲际弹道导弹。

That's led weapons designers to build ICBMs with multiple stages instead of just one fuel tank and set of engines.

这导致武器设计者建造多级洲际弹道导弹，而不仅仅是一个燃料箱和一组发动机。

No. Experts have been saying for some time that North Korea's plan was first to develop tactical nukes, then progress to upgrading intercontinental ballistic missiles, ICBMs, and nuclear tests.

还没有。一段时间以来，专家一直认为，朝鲜的计划是首先发展战术核武器，然后是升级洲际弹道导弹、进行核试验。

UNIDENTIFIED MALE: These bases use encrypted communications but valuable intelligence could be gathered on the people working with the ICBMs and the area could also be targeted with network attacks.

这些基地使用加密通信，但可以收集有关洲际弹道导弹工作人员的宝贵情报，该地区也可能成为网络攻击的目标。

ICBMs can also carry warheads, the toxic or explosive stuff that makes them especially dangerous and a big concern these days is having an ICBM that carries nuclear warheads.

洲际弹道导弹还可以携带弹头，这种有毒或爆炸性物质使它们特别危险， 如今人们非常担心的是拥有携带核弹头的洲际弹道导弹。
