For SpaceX, the argument positions Starlink and Starshield as dual-use defence infrastructure beyond connectivity, alongside its launch and Space Force contracts. The claim that stealth is "dead" remains the authors' view; detection, tracking and weapons-grade targeting are different thresholds, and the NRO does not disclose the capabilities of its satellites.
