As adversaries seek to exploit the cyber and space domains, we are committed to maintaining superiority and resilience. 

Our space and cyber initiatives include: 

  • Deploying Joint Combatant-Command Cyber Assessment Teams and conducting Defend Forward Operations to strengthen cyber defenses. 

  • Supporting partner nations with technical expertise, incident response, and intelligence sharing in the cyber domain. 

  • Enhancing space domain awareness through the acquisition of fixed and mobile telescopes and commercial space-based initiatives. 

  • Establishing United States Space Forces Southern to integrate space capabilities in support of regional security and deterrence. 

These efforts ensure that the United States and its partners are prepared to counter threats in the space and cyber domains, protect critical infrastructure, and maintain a technological edge over adversaries.
