North Korea may reveal more than a dozen heavy missile launchers at its upcoming Oct. 10 military parade, analysts said on Wednesday, citing recent satellite imagery showing a parade training area and workers reinforcing a bridge in Pyongyang.

A newly built heavy equipment storage unit containing more than 100 garages were identified at the Mirim Parade Training Ground, according to a 38 North analysis of Sept. 14 satellite imagery. Some of these garage bays even have space for North Korea’s largest transporter erector launchers (TELs) and missile systems.

Four new temporary structures were also built adjacent to the new garages
