China's domestically developed large transport aircraft Y-20 for the first time conducted a large-scale military operation in a situation other than war, arriving Thursday in Wuhan with medical reinforcements and supplies to join the battle against the COVID-19 outbreak.

A total of 11 transport aircraft from the Chinese People's Liberation Army (PLA) Air Force, including multiple Y-20s, Il-76s and Y-9s, arrived at Wuhan's Tianhe International Airport from multiple locations across China on Thursday morning.

This is also the first time the PLA Air Force has conducted a large-scale emergency aerial delivery mission systematically featuring large and mid-sized cargo planes.
