WASHINGTON — The strange objects, one of them like a spinning top moving against the wind, appeared almost daily from the summer of 2014 to March 2015, high in the skies over the East Coast. Navy pilots reported to their superiors that the objects had no visible engine or infrared exhaust plumes, but that they could reach 30,000 feet and hypersonic speeds.
“These things would be out there all day,” said Lt. Ryan Graves, an F/A-18 Super Hornet pilot who has been with the Navy for 10 years, and who reported his sightings to the Pentagon and Congress. “Keeping an aircraft in the air requires a significant amount of energy. With the speeds we observed, 12 hours in the air is 11 hours longer than we’d expect.”
In late 2014, a Super Hornet pilot had a near collision with one of the objects, and an official mishap report was filed. Some of the incidents were videotaped, including one taken by a plane’s camera in early 2015 that shows an object zooming over the ocean waves as pilots question what they are watching.
“Wow, what is that, man?” one exclaims. “Look at it fly!”
No one in the Defense Department is saying that the objects were extraterrestrial, and experts emphasize that earthly explanations can generally be found for such incidents. Lieutenant Graves and four other Navy pilots, who said in interviews with The New York Times that they saw the objects in 2014 and 2015 in training maneuvers from Virginia to Florida off the aircraft carrier Theodore Roosevelt, make no assertions of their provenance.
But the objects have gotten the attention of the Navy, which earlier this year sent out new classified guidance for how to report what the military calls unexplained aerial phenomena, or unidentified flying objects.
Joseph Gradisher, a Navy spokesman, said the new guidance was an update of instructions that went out to the fleet in 2015, after the Roosevelt incidents.

“There were a number of different reports,” he said. Some cases could have been commercial drones, he said, but in other cases “we don’t know who’s doing this, we don’t have enough data to track this. So the intent of the message to the fleet is to provide updated guidance on reporting procedures for suspected intrusions into our airspace.”
The sightings were reported to the Pentagon’s shadowy, little-known Advanced Aerospace Threat Identification Program, which analyzed the radar data, video footage and accounts provided by senior officers from the Roosevelt. Luis Elizondo, a military intelligence official who ran the program until he resigned in 2017, called the sightings “a striking series of incidents.”Navy pilots from the VFA-11 “Red Rippers” squadron aboard the aircraft carrier Theodore Roosevelt in 2015.

The program, which began in 2007 and was largely funded at the request of Harry Reid, the Nevada Democrat who was the Senate majority leader at the time, was officially shut down in 2012 when the money dried up, according to the Pentagon. But the Navy recently said it currently investigates military reports of U.F.O.s, and Mr. Elizondo and other participants say the program — parts of it remain classified — has continued in other forms. The program has also studied video that shows a whitish oval object described as a giant Tic Tac, about the size of a commercial plane, encountered by two Navy fighter jets off the coast of San Diego in 2004.
Leon Golub, a senior astrophysicist at the Harvard-Smithsonian Center for Astrophysics, said the possibility of an extraterrestrial cause “is so unlikely that it competes with many other low-probability but more mundane explanations.” He added that “there are so many other possibilities — bugs in the code for the imaging and display systems, atmospheric effects and reflections, neurological overload from multiple inputs during high-speed flight.”
