Experts: The USA's new space weapons

Experts: The USA's new space weapons – electronic warfare The indication from the US government that they have now "placed weapons in space" is likely about electronic warfare against enemy satellites, according to experts. – Going with this is a paradigm shift, since it was previously taboo to talk about militarizing outer space, says Anna Maria Wårlind, an expert at FOI. China warns the US about a space weapons arms race. The cryptic message from the US Air Force Secretary Troy Meink on Tuesday, that the US now has weapons in space and "will use them to defend American forces against hostile activities," is seen as a geopolitical shift – but is also too vague to be a deterrent to enemies, according to American experts. Meink's statement is "enormous," according to security analyst Victoria Samson. "It is the first time someone has said this from an official source. It also means that the US must accept that the Chinese and Russians are doing the same thing. I don't think it will benefit US security," she says to the website Defense One. According to Samson, the US's new weapons are likely space-based equipment for electronic warfare. It could involve disrupting the satellites of hostile countries, for example, when they are used for targeting the US. This could be done with electromagnetic pulses or lasers that burn or blind the satellites. China urged the US on Thursday to stop the weapons buildup in space, because "other countries will be forced to respond," in a race. Meink's remarks were interpreted by Chinese security analysts as a shift away from the land-based defense of space that has prevailed until now, writes Reuters. Since 1967, there has been a convention that prohibits the deployment of weapons of mass destruction in space, but not conventional weapons. Since then, Russia, the US, China, and India have developed technology that can be used to attack their rivals' satellites, which are important for military communication, surveillance, and navigation. – For example, you can get close to another satellite with a satellite to service it or to move a piece of debris to a safe place. But you can also tag someone and prevent them from carrying out their tasks. The major countries are developing capabilities with the aim of controlling the space domain around their objects, says Torbjörn Sundberg, a researcher at the Defence Research Institute, FOI. The space nations have also experimented with shooting down their own obsolete satellites with ground robots. The US has long complained about China and Russia's activities in space and expressed a need to control space. Taking the plunge on their own side suggests that they really have weapons there, according to Anna Maria Wårlind, a researcher at FOI. – It is the leading superpower and the most advanced space nation. They want to give this signal that they lead the field. If you get into that narrative, then there is probably the capability there, she says. Wårlind makes the same assessment as the international experts – the big thing is the US's shift in course, choosing to talk about space weapons, something that was previously taboo. – It says something more about how tense the situation is, and how the domain is developing, that you are in a paradigm shift in that way. It is difficult to say anything about it technically, it is probably something that will not cause large amounts of debris, but disrupt or prevent satellite communication. Since satellites move at such high speeds, tens of thousands of kilometers per hour, and develop enormous kinetic energy, they can be used as so-called kinetic weapons, where you simply let them collide with enemy satellites. However, this would create enormous clouds of debris and dust in space, which in a chain reaction risks destroying a large amount of other satellites, something that would be devastating. Therefore, it is assumed that the weapons the US is talking about are not kinetic. In the space defense that US President Donald Trump is betting on, the so-called Golden Dome, which is to protect the entire country from attacks with intercontinental robots, there are however plans to use satellites as kinetic weapons, as part of a ground defense robot. The idea is that they will circle at a low altitude above the earth and be able to collide with incoming missiles, and that the debris formed will burn up in the atmosphere when it falls to the earth. But a review made by the Washington Post states that it will probably require tens of thousands of satellites for anyone to be close enough to hit a missile on its way to the US during the launch phase. It would take decades to achieve this, at astronomical costs. According to Troy Meink, the US is also developing a system with space-based robots, interceptors, that will be part of the Golden Dome defense. Why the indication about space weapons now, the minister does not want to explain, more than that "there are many factors that affect how we talk about these things," that it is intended to be a deterrent and that it will be used to "control space." According to Johan Köhler, department head of the Space Agency, which is the Swedish authority for civil use of space, it is difficult to speculate what the US marking means. – But it is naturally a change in practice when it comes to the militarization of space, that is something we must monitor in a general world analysis, he says.
