Summary
Hill Air Force Base's official Utah Test and Training Range fact sheet describes UTTR's mission, airspace, land footprint, history, personnel, and range capabilities.
Useful Claims
- The fact sheet describes UTTR as a Department of Defense Major Range and Test Facility Base.
- It says UTTR supports operational test and evaluation for weapons requiring a large safety footprint and is the only location capable of supporting overland cruise-missile testing.
- It says UTTR is used for air-to-air combat, air-to-ground inert and live practice bombing, and gunnery training by DoD aircrews.
- It places UTTR about 100 miles west of Hill Air Force Base in northwestern Utah and eastern Nevada.
- It identifies UTTR as the largest block of overland contiguous special-use airspace within the continental United States, measured from surface or near surface.
- The history section traces the range through Wendover, Hill, and Dugway range complexes and says Air Force Systems Command redesignated them as UTTR in 1979.
Reliability Notes
This is official Air Force evidence and is strong for mission, capabilities, footprint, and institutional history. It should be paired with environmental, Tribal, local, and independent defense-infrastructure sources for impacts and contested land-use questions.
