Alaska Communications System

The ACS handled the radioteletype, radio telephone, 500 kHz ship-to-shore frequencies, collected communications intelligence, and other services for more than half a century in Alaska.

[3] The Army Signal Corps (which develops, tests, provides, and manages communications and information systems support for the command and control of all the U.S. armed forces) connected military posts with each other and with the rest of the continental United States.

This system of thousands of miles of suspended landlines and submarine cable included the first successful long-distance radio operation in the world.

[4] An important message, such as General MacArthur's World War II demand for the surrender of the Japanese, was received, automatically recorded as printed text and parallel punched holes on paper tape, and could then be relayed on to other stations.

In the U.S. that year, the U.S. Army Signal Corps began to establish isolated forts (meteorological stations) throughout the Western territories.

[5][6] In 1900 the Congress appropriated nearly a half a million dollars for the purpose of establishing a land and underwater communications system connecting the various military posts in Alaska with the rest of the United States.

[8] From 1931 the Army Signal Corps did not own a cable ship and so the system deteriorated until the beginning of World War II in 1941.
