The U.S. Space Development Agency (SDA), led by Derek Tournear, is focused on deploying a resilient Proliferated Warfighter Space Architecture of low Earth orbit satellites to enhance rapid sensor-to-shooter connections. While not overly concerned about anti-satellite attacks, Tournear emphasizes the critical threats of cybersecurity vulnerabilities and supply chain fragility, which could undermine the network’s effectiveness. SDA has faced delays in satellite launches due to supply chain issues, such as shortages of resistors and optical communication terminals. To mitigate risks, the agency prioritizes sourcing U.S.-developed software and ensuring the provenance of all satellite components. Tournear and other defense leaders, including Gen. Michael Guetlein, highlight the need for industrial base reforms, advocating for reduced reliance on single suppliers and increased production capacity to address systemic inefficiencies and prepare for crises.
