'NKorea's missile launches were nuclear attack drills'_我的网站

一 |     9月20日消息，当地时间周一，SpaceX在对星际飞船系统原型的7号超级重型助推器进行静态点火测试时，首次同时启动7部猛禽发动机，这也是公司同时启动火箭发动机数量最多的一次测试。星际飞船是高度有50米的可重复使用航天器，将由70米长、搭载33部猛禽发动机的超级重型助推器送入轨道。SpaceX最近一直在测试7号助推器，为计划中的星际飞船系统首次轨道飞行做准备。在周一顺利完成发动机静态点火测试之后，SpaceX创始人兼首席执行官埃隆·马斯克（Elon Musk）在社交媒体Twitter上表示，所有7部猛禽发动机的燃烧室压力“看起来都很正常。”在随后的一条Twitter中，马斯克表示，“7号助推器现在返回高舱进行系统稳健性升级，8号助推器将移动到发射台继续进行测试”。

It comes as intelligence suggests North Korea is preparing to hold its first nuclear weapon test in five years, the BBC reported.

In recent weeks, Pyongyang has launched seven sets of missiles in response to recent US and South Korea drills.

On Monday, state media published extensive reports claiming the missiles were designed to carry tactical nuclear weapons.

These are small short-range weapons intended for use on the battlefield. They said the military practised loading the missiles with dummy versions of these miniaturised warheads.

They also claimed to have successfully simulated hitting South Korea's military bases, ports and airports, and said the launches were a warning to US and South Korea.

State news agency KNCA ran photos of leader Kim Jong-un overseeing and "guiding" the tests.

US and South Korea intelligence officials have been suggesting that the North may soon test a nuclear weapon for the first time since 2017.

Experts believe it could also use the opportunity to detonate a smaller tactical device for the first time - the sort which would fit into the missiles it has been testing, the BBC reported.

Last month Kim declared North Korea an "irreversible" nuclear power and revised its laws, allowing it to use nuclear weapons pre-emptively. Its previous policy had been to only use such weapons in response to an attack.

It has also markedly stepped up its frequency of missile firings this year, carrying out over 40 missile launches this year so far - its most ever.

Most of the launches in the past fortnight have been short-range missiles, which landed in the sea between North Korea and Japan.

But North Korea also fired a longer-distance missile over Japan last Tuesday - which analysts say is a new intermediate-range ballistic missile, based on the weapon's design.

This year has seen the North test-fire missiles from a variety of launch sites including trains and convoys - moving platforms which would make it harder for the weapons to be destroyed in a strike, analysts have suggested.

The analysts told BBC that Monday's state media reports framed the recent launches as "tactical nuclear operations units" - instead of describing them purely as missile tests - suggesting that North Korea has now developed a system for deploying smaller, short-range nuclear weapons.

The 25 September-October 9 barrage were a response to the US deploying its nuclear-powered aircraft carrier the USS Ronald Reagan to waters around the Korean peninsula, and holding joint drills with Seoul and Tokyo.

The acceleration marks a significant change from when Pyongyang pursued denuclearisation talks with then US President Donald Trump between 2018 and 2019.

Analysts also said North Korea is also reacting to South Korean President Yoon Suk-yeol's hawkish stance to the North and closer ties with the US.

UNI ING。”马斯克所说的“全堆栈”包括位于超级重型助推器顶部的星际飞船，它们共同构成了世界上最高的火箭，总高有120米。SpaceX最近完成的这次发动机静态点火测试是8月31日火箭发动机点火数量的两倍。

三 | 在那次对超级重型助推器进行静态点火测试时，SpaceX启动了三部猛禽发动机，这也是公司首次对超级重型助推器上搭载的多部发动机同时进行静态点火测试。此前，SpaceX曾在8月9日的一次静态点火测试中同时启动星际飞船6部猛禽发动机中的2部。

四 | SpaceX还没有公布对星际飞船系统进行全栈测试的预计日期。

五 | 但公司表示，它的目标是在未来几个月内对飞船原型进行首次轨道测试。
