LeoLabs is a US operator of a global phased-array radar network for LEO and VLEO tracking, the commercial gap-filler for the aging, northern-skewed Space Surveillance Network (with equatorial and Southern Hemisphere sites), plus a Delta product giving operators alerts on close approaches and obscured deployments. It was named to the competitive range of MDA's SHIELD homeland-defense program in January 2026 (a $151B ceiling, not an award), and its radar-versus-optical complementarity with Slingshot defines the space-sensing duopoly. Revenue is estimated at 10-100m from repeated annual government contracting.
