Guri (G-203) Airport

The primary reason for closure was urban encroachment and severe noise pollution. Originally built in a relatively rural area, the heliport became surrounded by large, dense residential apartment complexes as the city of Guri expanded. Decades of persistent noise complaints from local residents and continuous pressure from the Guri city government prompted the Ministry of National Defense to agree to relocate the base. This decision was made to resolve the long-standing conflict between the military and the civilian population and to free up prime real estate for urban development.

The site of the former heliport has been completely demolished. It is currently a massive construction site, part of the 'Guri Hangangbyeon Urban Development Project' (구리 한강변 도시개발사업). This project aims to transform the 1.5 million square meter area into a new urban center featuring smart city technology, residential housing, commercial facilities, and public parks. All runways, helipads, and military buildings have been removed to make way for this new development.

G-203 was a strategically important Republic of Korea Army (ROKA) heliport, not a civilian airport. The identifier 'KR-1087' was a non-standard, likely internal or database-specific code. The base housed a ROK Army aviation battalion, operating helicopters such as the UH-1H Iroquois and later the UH-60 Black Hawk. Its location in the Seoul Capital Area made it crucial for supporting the ROK Army Capital Defense Command (수도방위사령부). Its primary missions included rapid troop mobility, logistics, command and control support, and medical evacuation (MEDEVAC) capabilities for military units defending the capital region.

There are zero prospects for reopening. The land has been permanently and irrevocably repurposed for a large-scale civilian urban development project. The military unit has been permanently relocated to a different region, and the ongoing construction makes any future aviation use at this location physically and politically impossible.
