Subj:    New address for Astronautics Corporate Headquarters

Effective January 2, 2020, Astronautics Corporation of America (Astronautics and/or ACA) is relocating its corporate headquarters from 4115 N. Teutonia Avenue, Milwaukee, Wisconsin 53209 to 135 W. Forest Hill Avenue, Oak Creek, Wisconsin 53154.  This is also its new corporate mailing address, replacing both its Teutonia Avenue and post office box addresses.

Currently, this relocation only affects its Milwaukee headquarters address and personnel.  Its Milwaukee-based manufacturing facility (Plant 4) and Federal Aviation Administration Repair Station remain at 1426 W. National Avenue, Milwaukee, Wisconsin 53204.

Astronautics’ main corporate phone number remains the same: (414) 449-4000, as does its corporate website address:

There will be no change to the direct email addresses and phone numbers of Astronautics’ personnel.  Please feel free to contact them as you have previously.

Astronautics’ new Oak Creek headquarters is located at the southwest corner of Forest Hill and Howell Avenues, near the Drexel Town Center.  For customers and suppliers traveling to visit us, Astronautics is minutes away from the Milwaukee International Airport.  Visitor parking is easily accessible on the north side of the building.

If you have any questions about Astronautics’ new headquarters location or about its products and services, please contact Brian Flagge, Senior Manager of Contracts Administration at or Karl Wolf, Manager of Purchasing at

Very truly yours,
