MPO Airport exterior

The exterior of the San Hieronymo airport.

The airport on the San Hieroynmo Peninsula was the location used for the arrival and departure of military and civilian aircraft in the region.


The main airport had two stories, including the main lobby/check-in area. There were also two rooms, one of which was accessible via the terminal observation area. The rooms had doors that presumably led to the tarmac. Within the main airport is a three-story air traffic control tower.

Besides the airport, there were also other buildings nearby.

MPO Airport interior

Interior of the San Hieronymo airport.

During the San Hieronymo Incident, a U.S. government official went into hiding at the airport, after having helped FOX Commander Gene steal the American-developed Metal Gear. Spies from Big Boss's resistance group pinpointed the location of the airport by tracking the flightpaths of both military and civilian aircraft traveling from the security base, warhead storage facility and hospital on the peninsula. Resistance members then tracked down the official and interrogated him for information related to Metal Gear.

The Airport icon in Metal Gear Solid: Portable Ops.

""Priority! Direct visual confirmation of multiple military and civilian aircrafts have helped to identify the location of the Airport.""
―Spy report from the Security Base/Warhead Storage/Hospital.

FOX operatives generally patrol the exterior of the facility, while the interior is overseen by male Soviet officers. On the ground floor there are two officers, with another on the second floor, in a hall with large glass windows behind the door. Continue heading up through the facility until you reach the watch tower: a room with computers and a column. Silently take out the FOX soldier guarding the area, then sneak up behind the government official staring outside the window. Interrogate the politician to find out the location of the Silo Entrance.
