Two large Bomb Shelters at the entrance of Jian Guo Village-I were estimated to be built in 1944 or so and completed the same time as the barracks. According to Japanese military documents, the bigger shelter was a “Bomb Shelter” as well as the “Combat Command Post,” and the smaller one was a “Power Station”; both were covered by earth and plantation for shielding purposes.
After the War, the airport and barracks became an Airforce base and Airforce dependents village; the Air Defense/Combat Command Post was used by the Communication Squad of Hu Wei Junior Pilot Training Class, which was later re-organized as the “Airforce Radio Station.” The current Activity Center was the office of the former Airforce Radio Station; relevant communication facilities of the radio station, such as wired telephone, radio transmitter, and so on, were equipped in the large shelter, where 4 or 5 people worked; the small shelter was used for storing diesel fuel and generators.
