The possible war-time applications of inspection satellites are obvious. “You can probably equip them with lasers, maybe put some explosives on them,” Zak said of the Kosmos triplets in 2015. “If [one] comes very close to some military satellite, it probably can do some harm.” To be clear, inspection satellites are not new. The U.S. government operates several of them. But secret inspection satellites are rare and potentially problematic, considering how easily they could be converted into weapons.
