You have to click on the links in the story to the origin source. There are several different ‘events’ chronicled. I believe the pictures in this story are from an event captured by a Hornet driver in March of 2019 off the eastern US seaboard.
There are no links in the linked articles. No text giving date or detail. Maybe the URL for the article is wrong?
These are probably our unmanned aerial vehicles and the photos are “leaked” for the benefit of the russians and chinese.
