A successful drone creates only a temporary operational window. Drawing on Russian and Ukrainian uncrewed systems, this TSB Insight explains the four clocks that determine whether a military can turn evidence into a fielded response before the advantage expires.

Russia’s Rassvet constellation now has 31 production-series satellites in orbit and predictable visibility windows over Ukraine. This update assesses what the network can already do, what remains unproven, and how it compares with Starlink and other sovereign LEO systems.

Russia has begun deploying the first operational elements of Rassvet, its emerging low-Earth-orbit satellite internet system. The project is still far from matching Starlink in scale, but it already deserves close attention: not as a copy of a Western model, but as a sovereign communications layer with potential consequences for Russian military resilience, remote civilian connectivity, Arctic operations, and state control over critical infrastructure.
