Southern Chan Country, Yang Province, Putuo Airport.

This airport is a permanent 4F military airport.

The so-called 4F level refers to the length and width of the airport runway; the larger the number, the longer the runway.

A 4F level airport has a runway length of at least 1800 meters and a width of several dozen meters, capable of accommodating the takeoff and landing of behemoths like the Boeing 737 and Airbus A380.

Unlike the Xavier Airport, a field airport, Putuo Airport has numerous permanent buildings and fully equipped facilities, naturally possessing strong defensive capabilities.

Especially after receiving funds from the Eight Nation Group, the other seven countries came with their own provisions to further reinforce and expand the airport.

Many ammunition and fuel depots, constructed with thick rebar and concrete, are partially buried deep within mountains and underground.

Nowadays, Putuo Airport is the largest military airport within the borders of Chan Country.
