North Korea may be preparing for a massive show of force, according to an analysis Friday of new satellite imagery that shows dozens of military aircraft parked wingtip to wingtip at an airport on the country's east coast.

The purpose of the display seen in commercial satellite images of Wonsan-Kalma International Airport taken Monday and Wednesday, and shared by analysts at the North Korea-watching 38 North website, remains unclear. However, the analysis suggested the North may be preparing for a site visit by leader Kim Jong Un and a possible demonstration of its air force capabilities.

"Similarly, it may be reviving the suspended annual Korean People's Army Air and Anti-Air Force Flight Drill Competition, which is usually observed by Kim Jong Un and demonstrates the air force's ability to destroy enemy targets," the analysis said.
