The U.S. Navy has recovered a ‘significant’ portion of a Chinese spy balloon that had been floating in the ocean off the coast of South Carolina, a defense official said.

The balloon, which was carrying sensors, was first spotted by the U.S. Navy in late January and was tracked by the U.S. military until it was recovered.

The sensors were recovered from the ocean by the U.S. Navy and are believed to have been part of a Chinese surveillance program.

The U.S. military has said that it has recovered a ‘significant’ amount of sensors from the balloon, which is believed to have been launched by the Chinese government.

The Chinese government has not commented on the incident.

The sensors are believed to have been used to monitor maritime activity in the region and to collect data on the environment.

The U.S. Navy has said that the sensors will be analyzed to determine their purpose and to determine what information was collected.

The incident is the latest in a series of incidents involving Chinese surveillance balloons being detected by the U.S. military in recent months.
