Base History \ Arrival
Rock Island Arsenal
The importance of the island was identified as early as 1809, when it was set aside as a federal military reservation by an Act of Congress. It has played key parts in every major US conflict dating back to the Black Hawk War of 1832. In 1969, the arsenal was placed on the National Register of Historic Places. In 1989, the original arsenal buildings were designated as National Historic Landmarks. A complete history of the installation, along with a mini virtual tour is available on the Rock Island Arsenal.
Rock Island Arsenal Garrison (USAG-RIA) is an active U.S. Army facility located in Rock Island County on a 946-acre island in the Mississippi River, between Davenport, Iowa and Rock Island, Illinois in an area known as the 'Quad Cities'. As a once thriving riverboat community, the Quad Cities have embraced their history in the form of many summer festivals and the home of Riverboat Gambling. Today, Rock Island Arsenal is our nation's largest government owned and operated arsenal.
The base operator's phone number is 309-782-6001 or DSN 312-793-6001.
