Why Mesothelioma Cases Occur in Tucson
Tucson's asbestos legacy is anchored by its military and defense presence. Davis-Monthan Air Force Base has been a major military installation since 1927 and is home to AMARG — the world's largest aircraft storage and preservation facility. Thousands of military aircraft are stored, maintained, and regenerated at the base, and asbestos was a standard component in older aircraft, maintenance hangars, and base buildings.
Raytheon Missile Systems (now RTX) operates one of its largest facilities in Tucson, manufacturing missiles and defense electronics. During peak asbestos use, the facility used asbestos in manufacturing operations, building insulation, and heat-resistant components. Defense manufacturing operations exposed workers to asbestos throughout the production process.
The 20-to-50-Year Latency Period
Mesothelioma has a latency period of 20 to 50 years. A worker exposed to asbestos at Tucson facilities in the 1970s may only receive a mesothelioma diagnosis in 2025 or later. This is why Tucson continues to produce new mesothelioma cases decades after asbestos use was restricted.
Tucson Electric Power operated generating stations where asbestos was standard in boiler insulation, turbine casings, and steam systems. Arizona's mining industry — including copper mining operations near Tucson — used asbestos in processing equipment, mill insulation, and industrial machinery.
The University of Arizona research facilities used asbestos in laboratory construction, building insulation, and research equipment during decades of campus expansion, adding to the region's overall asbestos exposure profile.
Tucson's Asbestos Legacy by the Numbers
Davis-Monthan AFB stores over 4,400 aircraft at AMARG. Raytheon Missile Systems employs over 13,000 workers in Tucson. Arizona's mining industry has been a major employer for over a century. Arizona allows 2 years from diagnosis to file a mesothelioma claim. Documenting your asbestos exposure history is a critical first step.
