Could this have been a classified payload to destroy North Korea’s own spy satellite or their next ICBM launch or Iran’s or Russia’s such that the real answers will never be forthcoming, meaning it is a ploy? Maybe even China?
Space-Track has cataloged the Zuma payload as USA 280, international designation 2018-001A. Catalog number 43098. No orbit details given. No reentry date given, but for a secret payload it might not be. Implication is Space-Track thinks it completed at least one orbit.
