The Three Sisters

Published: January 9, 2007

While they may seem quaint or even primitive by modern standards, upon their completion in 1913, the Navy’s Radio Station Arlington Towers were considered to represent the height of cutting edge communications technology.

In their day, “The Three Sisters” as they were known, were the second largest manmade structure in the world behind only the Eiffel Tower, with the tallest of the three standing a full 45 feet higher than the Washington Monument.

Located at the intersection of Columbia Pike and Courthouse Road, the towers were built to launch the Navy’s effort to establish a worldwide communications network. Using the call letters NAA, the towers functioned to provide the first long distance radio conversation, the first transoceanic radio telephone circuit (fittingly, to a French station broadcasting from the Eiffel Tower), and served to introduce the regular broadcasts of time signals, which was important to ships at sea who relied on accurate time checks for navigational purposes.

The towers were taken down in 1941 upon the opening of National Airport as they were considered to be an aviation hazard. Today, the site at Columbia Pike and Courthouse road continues to be occupied by military communications departments, chiefly the Defense Communication Agency. There are photographs like the one above, showing the Three Sisters and cavalry exercises from Fort Myer, and you can find out more information on the towers using newspapers on microfilm, all in the Virginia Room.

    The site of the three sisters was recently renovated as a Navy Service Center for the relocation of the tenants of the Navy Annex. During the renovation, excavations unearthed footings for one of the towers. The site continues to be an archeological zone. Two of the original “out-buildings” are still standing. There is a rich history of wireless voice communication associated with the site.

    It is my understanding that the three sisters were dismantled and reassembled in Annapolis.

    Thank you both for the additional information – the link to the google map showing the three towers is especially interesting.

    We’ll try to get the original photo back this week, too.

    Arlington was the first of four identical tower sets. I’m working on the history of USNRTS Chollas Heights in San Diego. The others were in Pearl Harbor, and in the Philippines. Who supplied the steel and who did the construction? It was San Diego that broadcast the attack on Pearl Harbor in 1941. The radio station at Pearl was down for routine maintenance.

    The “Three Sisters” antenna support towers were dismantlement for scrap, not moved to Annapolis.
