🛫 Massive Underground Air Base Carved Into Mountain

One of the world’s largest underground air bases was built by excavating into solid rock, with kilometers of internal tunnels, fighter hangars, and integrated runways hidden within the mountain — showcasing extraordinary military engineering and hardened infrastructure.

• The base features approximately 3.5 km of buried tunnels carved directly into mountain rock, accommodating aircraft and support facilities below ground.

• Underground hangars like these combine aircraft shelters, tunnels, fuel and weapons storage, living/maintenance spaces, and access to runways from inside the mountain.

• Such underground airbases aim to protect military aircraft from air strikes and extreme weather by housing them in reinforced rock.

Underground hangars and air base tunnels are rare but strategic: they provide enhanced concealment and defense for assets, and the engineering reflects a high level of military infrastructure capability — often associated with Cold War or high‑threat environment planning.
