Aircraft Shelters in Vietnam

摘要

The shelters are 72-foot-long, 48-foot-wide, and 24-foot-high corrugated steel arch structures which are covered with concrete for protection against rocket and mortar fire. The arches are made of 10-gauge galvanized steel with dimensions to fit into the 52-foot-wide steel revetments, built by Air Force troops in 1966 and 1967. The shelters are placed in 8-gauge channel base plates which are bolted to the concrete ramp. Each shelter is composed of 324 panels (with a total weight of 31 tons) bolted together into 36 rings with 15,141 bolts.
