War in space is no longer science fiction

Editor’s note: On February 14th the chair of America’s House intelligence committee asked Joe Biden to declassify information about “a serious national-security threat”, reportedly concerning a new Russian weapon in space.

THE FIRST shot of the next war between the world’s big powers, it is often said, will be fired in space. As conflict spreads on Earth, ill omens are emerging in the firmament. As countries race to develop new capabilities in space, some are also building the forces and weapons to fight beyond the atmosphere. On January 28th Iran said it had launched three satellites; Western countries fear they could be used in its ballistic-missile programme. Russia’s invasion of Ukraine has opened a new chapter in space war. But America’s biggest dread is China, which seeks to match if not surpass America’s primacy in the heavens. Admiral Christopher Grady, vice-chairman of America’s joint chiefs of staff, explains it bluntly: “Space has emerged as our most essential warfighting domain.”
