U.S. military’s newest weapon against China and Russia: Hot air

The high-altitude inflatables, flying at between 60,000 and 90,000 feet, would be added to the Pentagon’s extensive surveillance network and could eventually be used to track hypersonic weapons.

The idea may sound like science fiction, but Pentagon budget documents signal the technology is moving from DoD’s scientific community to the military services.

“High or very high-altitude platforms have a lot of benefit for their endurance on station, maneuverability and also flexibility for multiple payloads,” said Tom Karako, senior fellow for the International Security Program and Missile Defense Project director at the Center for Strategic and International Studies.
