In the summer of 2019, several U.S. Navy ships operating off the coast of San Diego reported repeated contacts with unidentified objects. These incidents occur over several consecutive nights and involve dozens of observers spread across several ships, including the USS Omaha, the USS Russell, the USS Kidd and others.
The objects are described as spherical, luminous, moving at unusual speeds and trajectories. Some reportedly made repeated “passes” around the ships. These incidents are formally recorded in the Navy's UAP reporting system.
