Today, Vice President Mike Pence gave a speech at the Pentagon in which he filled in some details on the administration's plans to add a distinct space force to the Department of Defense. The speech coincided with the completion of a Pentagon report that provides a greater sense of how the space force would be structured and fit in with the existing Defense bureaucracy. But there's still a lot unspecified regarding whether non-defense space activities, such as those pursued by the NSA, will be affected by the changes.

A significant portion of Pence's speech was devoted to arguing that this is the right time for a space force. Some of the arguments date back to the Cold War, like the development of anti-satellite weaponry, a concern enhanced by China's testing of such a weapon about a decade ago. Others are more recent, like the development of things such as GPS-jamming hardware. One of the arguments stretched logic a little, as Pence cited the threat of hypersonic missiles, which pose a risk because they don't enter space and therefore can't be targeted for antimissile interception there.
