746th Test Squadron
The 746th Test Squadron, also known as the Central Inertial Guidance Test Facility, was established in 1959 to test and validate intercontinental ballistic missile guidance systems. Today, they are recognized by the DoD and by AF/TE as the leader in GPS electronic open-air combat threat environment testing and as the “center of excellence” for testing all aircraft and missile inertial guidance systems. The 746th is responsible for all DoD Global Positioning System integration testing on all current and future weapon platforms. The 746th operates a fleet of highly modified ground test vehicles providing low-cost and comprehensive navigation and test support. As the Air Force leader in inertial testing, the 746th utilizes sophisticated centrifuge and rate-table test assets to provide highly accurate component test results. Additionally, the squadron provides all instrumentation support for laboratory, ground vehicle, flight test and Holloman High Speed Test Track testing within the group.
