The United States Taiwan Defense Command was a sub-unified command of the United States armed forces. It was originally formed as the Formosa Liaison Center (founded in 1955 after the signature of the US-Taiwan Mutual Defense Pact of December 1954 and the first Straits crisis of Sept. 1954). In November 1955, the FLC become the Taiwan Defense Command. The command reported directly to the Commander-in-Chief Pacific (CINCPAC). The command was composed of personnel from all branches of the U.S. armed forces and had its headquarters in Taipei. The first commander of the USTDC was Alfred M. Pride (command of the U.S. Seventh Fleet).
