Checkmate 10, part of the same ten-satellite April 2023 SDA Tranche 0 launch that proved small, mass-produced military satellites could form a genuine self-healing mesh network in orbit — each satellite carrying at least four optical laser crosslinks, enough to talk simultaneously with satellites ahead and behind it in the same orbital plane plus two more in entirely different orbital planes.
