WASHINGTON — The White House on Monday defended President Joe Biden’s decision to shoot down three low-flying, aerial objects over U.S. and Canadian airspace in the past three days, but said it had not determined yet exactly what the objects were, who owned them or what they were doing.
“We have not yet been able to definitively assess what these most recent objects are,” John Kirby, a spokesman for the National Security Council, said at a White House briefing.
“And while we have no specific reason to suspect that they were conducting surveillance of any kind, we couldn’t rule that out,” he added.
Each of the three crafts was the size of a small car and was floating on prevailing winds.
The first of the three crafts was destroyed on Friday in U.S. airspace over Alaskan waters. It was cylindrical and had been floating at around 40,000 feet in altitude, Kirby said, posing a threat to civilian aircraft.
On Saturday, the U.S. and Canada coordinated the use of American military jets to shoot down a second object, this time overland in the remote Canadian Yukon.
That craft was similar in size, shape and flight altitude to the one that was shot down Friday, Kirby said.
The third object was octagonal and was flying lower, at approximately 20,000 feet. That object was shot down Sunday over Lake Huron, on the U.S.-Canadian border.
Kirby said the sharp increase in the number of objects shot down in recent days was partly a result of heightened radar sensitivity, implemented in the wake of the discovery of a massive Chinese spy balloon in late January.
That balloon was 200 feet high and carried a payload of surveillance equipment. Defense officials opted to let it float over the continental U.S. for a week, before shooting it down Feb. 4 above the waters off South Carolina.
“One of the reasons we’re seeing more, is because we’re looking for more,” Kirby said Monday, taking pains not to call the three latest floating objects “balloons.”
“We need to separate [the three recent objects] from the Chinese spy balloon,” he said. In the spy balloon situation, “we knew what it was, we knew where it was going, we knew what it was doing.” This time around, there are more questions, he said.
“We know that [Chinese] surveillance balloons have crossed over dozens of countries on multiple continents around the world, including some of our closest allies and partners,” said Kirby.
“We also know that a range of entities, including countries, companies, research and academic organizations operate objects at these altitudes for purposes that are not nefarious at all, including scientific research,” he said.
The effort to salvage debris from the latest incidents has been hindered so far by remote terrain and freezing temperatures, both on land and in the deep waters of Lake Huron and the Arctic Ocean.
On Monday, Secretary of Defense Lloyd Austin said that American and Canadian teams had “not recovered any debris” yet from the three most recent objects. “We don’t know if they were actually collecting intelligence,” he told reporters shortly after landing in Brussels.
In addition to the more immediate recovery and forensic investigations of the objects themselves, the Biden administration took steps Monday to address the broader implications of these objects for American defense and foreign policy.
A new, interagency task force has been assembled in order to study the broader ramifications of “detection, analysis and disposition of unidentified aerial objects that pose either safety or security risks,” Kirby told reporters at the White House.
Beijing has denied any involvement with the three most recent floating objects.
And while the Chinese government admitted that the surveillance balloon shot down Feb. 4 was indeed Chinese, it insisted the high-tech aircraft was merely an errant weather balloon blown off course.
High-altitude weather balloons have a maximum diameter of approximately 20 feet, according to the National Weather Service. The Chinese surveillance balloon was around ten times that size, according to a Defense Department official.
