The Hàm Rồng Bridge (Cầu Hàm Rồng (Dragon’s Jaw Bridge)), also known as the Thanh Hóa Bridge spans the Sống Mà river 3 miles northeast of Thanh Hóa, the capital of Thanh Hóa Province in Vietnam. From 1965 and the initiation of Operation Rolling Thunder during the Second Indochina War (1955-1975), it was the primary objective of many attacks by US Air Force (USAF) and US Navy aircraft, which failed to destroy the bridge due to an impressive North Vietnamese air defense network comprised of five air defense regiments in the area. Eventually, in 1972, and the initiation of Operation Linebacker, the bridge was destroyed by USAF F-4 Phantoms using laser-guided bombs and US Navy with advanced and conventional bombs.
