USS Princeton 2019 aerial observations

Record summary

USS Princeton was reportedly involved in the cluster of unexplained aerial observations around Navy vessels operating off Southern California in July 2019. Accounts describe radar or visual contacts and coordination with other ships, but publicly available narratives vary considerably about what Princeton specifically observed. The ship is a useful identifiable lead because it is repeatedly named in reporting and later documentary discussions. Conventional possibilities include drones, balloons, aircraft, and sensor or identification errors; the record requires reconstruction from primary sources.
