# Golden Dome missile defense requires orbital compute because ground-based processing transmission latency exceeds time-critical decision windows for missile interception

James O'Brien, chief of U.S. Space Command's global satellite communications and spectrum division, stated 'I can't see it without it' when asked whether space-based compute will be required for Golden Dome. The operational logic is specific: data latency between sensors and decision makers limits response time in missile defense scenarios where seconds matter. On-orbit data centers shift compute requirements from ground to space, putting processing power physically closer to spacecraft and reducing transmission latency. This creates faster tactical decision-making in time-critical interception scenarios. The statement is notable for its directness—not hedged language about future possibilities, but present-tense architectural requirement for an active $185B program (recently increased by $10B to expand space-based sensors and data systems). The U.S. Space Force has allocated $500M for orbital computing research through 2027, indicating this is not speculative but an operational requirement driving procurement. This establishes defense as the first named anchor customer category for orbital AI data centers, with a specific technical rationale (latency reduction for time-critical decisions) rather than general compute demand.
