C-451 Heliport

Military reorganization and data re-designation. The heliport was not closed due to economic reasons, lack of use, or an accident. It was located within the headquarters of the Republic of Korea (ROK) Army's 1st Field Army. In 2019, this command was merged with the 3rd Field Army to create the new, larger Ground Operations Command (GOC), which is headquartered at the same site. During this transition, the original heliport designator (C-451 / KR-0064) was likely decommissioned or superseded by a new, non-public military designator. The 'closure' reflects its removal from public aviation databases rather than a cessation of helicopter activity at the location.

The physical site is an active, high-security military installation. It is now the headquarters for the ROK Army's Ground Operations Command (지상작전사령부), the largest formation in the South Korean military. While the specific 'C-451' identifier is no longer in use, the base continues to operate one or more heliports to serve the needs of the new command. Satellite imagery confirms the presence of helipads within the base perimeter. The site is strictly off-limits to the public.

C-451 was a strategically important military heliport serving as the primary air facility for the headquarters of the ROK Army's 1st Field Army Command in Wonju. The 'C-###' designation is typical for US or ROK military helipads. Its operations were exclusively military and crucial for:
- **VIP Transport:** Moving high-ranking military commanders (e.g., the commanding general of the 1st Army), defense officials, and government dignitaries.
- **Command and Control:** Facilitating rapid movement of command staff for inspections, briefings, and overseeing military exercises.
- **Liaison:** Supporting operations with nearby US and ROK military units.
The 1st Field Army was responsible for defending South Korea's eastern and central frontline, making this heliport a key logistical asset for the command's leadership.

Zero. There are no plans or prospects for reopening this facility to the public or under its old designation. As it is located within the secure perimeter of one of South Korea's most important military command centers, any and all helicopter operations are, and will remain, exclusively for military use.
