Testing its satellite killer systems, Russia has again reminded us that we can’t sit idle in the face of its weapons evolution.

According to the head of U.S. Space Command, Gen. Jay Raymond, “Russia conducted a nondestructive test of a space-based anti-satellite weapon.” The July 15 test involved a satellite releasing an “object in proximity to another Russian satellite, which is similar to on-orbit activity conducted by Russia in 2017 and inconsistent with the system’s stated mission as an inspector satellite.” Raymond added that the system is the same as one that “maneuvered near a U.S. government satellite” earlier this year. It’s “further evidence,” he said, “of Russia’s continuing efforts to develop and test space-based systems and consistent with the Kremlin’s published military doctrine to employ weapons that hold U.S. and allied space assets at risk.”
