It was only a matter of time. Canada wants to develop its own version of the US Space Force later this year. According to media reports, the Canadian Space Division would eventually employ about 270 people, versus about 16,000 in the US program.
The two nations are not alone. A quick check on Wikipedia shows space forces in numerous countries, from Italy to Peru, though the definition of “space force” is pretty wide.
Even with their growth, not everyone is a fan. The Cato Institute had this to say in its 2020 report, Space Force: Ahead of Its Time, or Dreadfully Premature?:
This investigation determines that the Space Force’s establishment is hobbled by unclear goals and uncertain effects, contending that the Space Force lacks a clearly defined organizational culture and a clear strategic purpose, both core elements of organizational success, and that the decision to create the service is premature at best and irresponsible at worst.
Not a ringing endorsement, but maybe a sign that some more thinking needs to go into the role of these new organizations. Yet just as the air force was a natural break away from the army, the space force is a natural offspring of the air force. What comes after that? Maybe a Lunar Force or a Martian Force when we start to occupy space. I would love to see those recruitment videos.
