The second MILSTAR Block I satellite, providing redundant nuclear command link coverage. MILSTAR-1 satellites prioritize survivability over capacity — they transmit slowly but are nearly unjammable, encrypted with military-grade algorithms, and hardened against nuclear electromagnetic pulse. Their purpose is to ensure that even in the most extreme scenario imaginable, the US chain of command can communicate a response.
