1. Observation Point, DaNang Port Facility, July 1966. Work involved dredging an entrance channel and turning basin to a depth of 39 feet; the bulk of the dredging material was used to fill a 45-acre tidal swamp, thereby creating a staging area for off-loading supplies. A 2,000 sheet piling bulkhead (seawall) was built. Two Jacket-type piers were to be installed. Each pier is 90’ x 600’. These piers were prefabricated at Poro Point, Philippines, by RMK-BRJ and shipped by barge to DaNang. The abutment for a third pier, a mobile DeLong type, was also in the job.

4. Qui Nhon Harbor. The man-made deep draft facility at the center of photo called for dredging an entrance channel and turning basin and depositing the fill on a Japanese constructed rode breakwater. The fill formed a 30-acre staging area. The T-shaped pier is composed of four joined mobile DeLong units.

6. Vung Tau Waterfront. In early 1966, Vung Tau was the waiting point for vessels awaiting availability of deep-draft berthing space upstream at Saigon. The DeLong mobile pier (upper-middle of photo), subsequently built, is a 2-berth linger pier extending from an earth causeway. In the center of the photo, 3 tankers are tied up to a POL pier.

8. LST Ramp at Cua Viet. Cua Viet is a location about 6 miles from the DMZ. Urgently needed for military operation, this LST ramp had to be built under extremely hazardous conditions (typhoons and heavy seas), and the prevalence of the Viet Cong who were very active in the area.

10. DaNang Airfield. Located southwest of DaNang, the second largest city in South Vietnam An existing French-built 7,900' runway was modernized and re­constructed into a 10,000' jet-capable airstrip. A new 10,000' asphaltic-concrete runway was added, with 1,000' concrete touchdown sections at either end, 1,000' over­ runs, taxiways, and warm-up aprons Other major items were an 80,000 SY aircraft parking apron, a 48,000 SY helicopter parking apron, and ancillary maintenance and support facilities.

A 10,000' concrete runway with connecting taxiway and warm-up apron were added. Tan Son Nhut was jointly used by commercial airlines and military aircraft of South Vietnam and the United States. At its peak, Tan Son Nhut had more daily takeoffs and landings than any other airfield in the world.

12. Bien Hoa Airfield located about 15 miles northeast of Saigon. Bien Hoa was the only military airfield in Vietnam prior to 1965. A 10,000' concrete runway and taxiway was built by RMK in 1963. A parallel 10,000' concrete runway was added in 1967.
