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’. Once a thriving riverboat community, the Quad Cities have embraced their history in the form of many summer festivals and the home of Riverboat Gambling with MegaReel games. 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.

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 homepage.

Critical Installation Information

The Midwest has four distinct seasons. There is usually some minor flooding in the spring along the Mississippi River and Rock River. You should carefully consider the consequences before selecting housing along the riverbanks where it is prone to flood.

  • Both Illinois and Iowa have strict seatbelt and child safety seat laws for children 80 lbs and under.
  • Government housing is limited. Most military families end up living in the local community. Additionally, three bedroom rental properties are at a premium. Be prepared to adjust your standards and desires when searching for rental property.
  • School busing is not provided by the Illinois Quad Cities school districts. Children living in Family Housing on Rock Island Arsenal are provided busing by USAG-RIA.
  • Most gas and electric companies in the area will offer a budget billing plan for homes that have been previously occupied. It is recommended that you accept this offer, as gas bills can reach several hundred dollars during the winter months and cause unexpected hardship. Budget billing will maintain the level of your bill each month at a similar rate.
