Moving to Tullahoma: Pros, Cons & What to Know
Moving to Tullahoma means moving into the home of the Arnold Engineering Development Complex (AEDC) -- the largest and most advanced complex of flight-simulation test facilities in the world -- a genuinely unique, aerospace/defense-testing economic identity unlike any other Tier B market built alongside this one.

AEDC's own official fact sheet (Arnold AFB, retrieved 2026-08-22) describes it as the largest and most advanced complex of flight-simulation test facilities anywhere in the world: 68 aerodynamic and propulsion wind tunnels, rocket and turbine engine test cells, space environmental chambers, arc heaters, and ballistic ranges, able to simulate flight from sea level to space and from subsonic speeds past Mach 20, with a replacement value exceeding $11.9 billion. More than 13 of its units offer capabilities unmatched anywhere else in the world.
Coffee County's largest employer, with a growing, well-documented economic impact
AEDC's FY2025 economic impact exceeded $1.2 billion -- up from $1.1 billion in FY2024 and $864 million in FY2021, a real, documented growth trend, not a one-year spike (Tullahoma News/DVIDS, retrieved 2026-08-22). Nearly 2,850 personnel worked at the base as of FY2025; a more granular FY2023 breakdown shows the workforce is overwhelmingly civilian-contractor (2,327 contractor/subcontractor employees) rather than active-duty military (37).
A working-age employer alongside an above-average senior population -- a real, disclosed tension
AEDC's own workforce skews working-age and contractor-heavy, which sits in genuine tension with Tullahoma's city-wide age data (a 19.1% 65-plus population share, above the national average -- see the retiring topic). Both facts are real and disclosed here rather than smoothed into a single simplified narrative; Tullahoma functions as both a real defense/aerospace employment hub and a city whose overall population skews modestly older than the national average.
Key takeaways
- Tullahoma is home to AEDC, the world's largest and most advanced flight-simulation test complex (68 wind tunnels/test units, $11.9B+ replacement value) -- a genuinely unique economic identity in this dataset.
- AEDC is Coffee County's largest employer, with a $1.2B+ FY2025 economic impact (a real, documented, growing trend) and nearly 2,850 personnel, overwhelmingly civilian contractors rather than active-duty military.
- This working-age, contractor-heavy employment base sits in real tension with the city's own above-national-average senior population share -- both facts are real and disclosed rather than resolved into one simple story.
- Middle Tennessee, Coffee County -- entirely within Tennessee's no-state-income-tax, high-sales-tax structure.
