F-105D Thunderchief 354th TFS/355th TFW, Thailand, 11th August 1967, "Dropping the Doumer Bridge"
General Background
The Republic F-105 Thunderchief first entered service in 1958. It had been designed for high-speed low-level penetration to deliver a nuclear bomb but was converted to deliver conventional payloads. It was the heaviest U.S. single-engined fighter ever made and could carry a greater bomb load than the B-17, B-24 or B-29. Best known for its action in Vietnam the F-105 flew over 20,000 combat missions with the loss of 382 aircraft out of the 833 produced.
The Aircraft
On 11 August 1967, the 355th conducted a raid on the Hanoi railroad and highway bridge. Thirty-six strike aircraft led by the 355th dropped 94 tons of bombs and destroyed one rail span and two highway spans on the northeast side of the bridge. The superstructure was damaged and the highway portion on the north side of the bridge, where it crossed the island in the river, was cut. This stopped the movement of an average of 26 trains per day with an estimated capacity of 5,950 short tons. Two aircraft were damaged, but no pilots were lost.
