Sourcing Aerospace and Defense Parts for Arizona Programs
Arizona aerospace buying is dominated by defense production and propulsion: missiles in Tucson, engines and auxiliary power units in Phoenix, Apache helicopters in Mesa and launch vehicles and satellites in Chandler and Gilbert. Most of it lands in two metros joined by I-10, and most of it carries defense flow-downs, export controls and desert storage problems that belong on the purchase order.

Who buys aerospace parts in Arizona
Arizona demand comes from a handful of large defense and propulsion plants plus two Air Force bases, not from airliner production. Each one pulls a different kind of part.
| Buyer | Where and what | Parts that tend to come up |
|---|---|---|
| Raytheon, an RTX business | Missile plant on Air Force Plant 44, on the south side of Tucson. Programs listed for the site include AMRAAM, Tomahawk, Standard Missile, Sidewinder, Stinger and Javelin. | Production tooling, test and handling fixtures, housings, brackets, machined castings, harness hardware |
| Honeywell Aerospace | Headquartered in Phoenix. Its Phoenix Engines campus has built engines and auxiliary power units for more than 75 years, and in April 2026 the company announced on site assembly of F124 jet engines there starting in 2027. | Rotating and static engine detail parts, test cell adapters, fixtures, gauges, ducting and tube assemblies |
| Boeing, Mesa | AH-64 Apache production plant just north of Falcon Field in northeast Mesa, building new and remanufactured AH-64E aircraft | Assembly tooling, ground support equipment, structural details, sustainment spares |
| Northrop Grumman, Chandler and Gilbert | A 633,000 square foot launch vehicle campus in Chandler that builds interceptors, targets and space launch vehicles, and a satellite campus in Gilbert that has produced NASA JPSS and Landsat 9 spacecraft | Vehicle structure, motor case and stage hardware fixtures, spacecraft brackets and panels, integration and handling GSE |
| Luke AFB and Davis-Monthan AFB | F-35A and F-16 pilot training west of Phoenix; A-10C, EC-130H and rescue units in Tucson, plus the 309th AMARG storage and reclamation group | Sustainment and repair parts, ground equipment, obsolete replacements |
The pattern is medium volume production with long program lives. A Tucson missile line or a Phoenix engine line can run the same part number for years, which makes source approval, first article and configuration control more important than raw speed.
Tucson: missiles, attack aircraft and the boneyard
Tucson buyers mostly need production support for missiles and sustainment parts for aging aircraft, and the city's storage yards shape how obsolete parts get found.
The missile plant
Hughes Aircraft opened the plant in 1951, sold it to the Air Force and kept operating it; Raytheon bought the Hughes missile business in 1997. The 2,900 acre site is about 95 percent government owned and sits beside Tucson International Airport. Work for this plant arrives with full DoD flow-downs: DFARS clauses, specialty metals rules, counterfeit prevention and, almost always, ITAR controlled data.
Davis-Monthan and AMARG
Davis-Monthan's host 355th Wing trains and deploys A-10C pilots. The base also holds the 309th Aerospace Maintenance and Regeneration Group, the storage yard most people call the boneyard. Tucson was picked for dry air that slows corrosion and caliche soil hard enough to park heavy aircraft without paving. A 2019 report put the inventory at about 3,280 aircraft of 80 types on roughly 2,600 acres, with 5,744 different parts reclaimed in the prior fiscal year.

AMARG is a supply source for the military, not a parts store for contractors. Reclaimed parts go back into the military supply system, and what the services no longer need goes to DLA Disposition Services.
- Reclamation serves the fleet first. The group pulls parts from stored aircraft when the active fleet needs them, and a 2019 report noted refurbished A-10 wings and landing gear pods being used to extend the A-10's service life. For some older types it is the only source.
- Surplus has rules. Once an aircraft is declared excess, DLA decides whether parts are sold intact or destroyed and sold as scrap, based on demilitarization codes and flight safety screening. A part that reaches the open market this way still needs paperwork you can trust.
- Commercial teardown is separate. Pinal Airpark in Marana, northwest of Tucson, hosts commercial storage and teardown, including a Part 145 repair station. Parts from airline teardowns follow FAA traceability rules, not DoD ones.
For a buyer, the practical point is that a used or reclaimed part is only as good as its traceability. Ask for the chain of custody back to an authorized source, the condition and any overhaul records, and test results when the part is an electronic component. When none of that exists, reverse engineering and remaking the part to a current drawing is often the safer route. See obsolete aerospace parts and counterfeit parts avoidance.
Phoenix metro: engines, Apaches, launch vehicles and fighters
The Phoenix metro adds engine, rotorcraft, launch vehicle and satellite production, with new work still arriving.
- Honeywell Aerospace. The F124 line will support the Beechcraft M-346N bid for the Navy jet trainer program, and Honeywell expects more than 400 engines over 13 years.
- Boeing Mesa. On the last day of 2025 the Army added a contract worth about 2.7 billion dollars for post-production support of the Apache fleet.
- Northrop Grumman Gilbert. The satellite campus, about 15 miles east of Phoenix, nearly doubled its production capacity with an expansion completed in 2022.
Phoenix industrial areas, airports and summer logistics are covered on the Phoenix CNC machining page.
Semiconductor fabs and machining capacity
Chip plants now compete with aerospace for the same machinists, precision shops and cleanroom trades in metro Phoenix, so plan quotes and schedules with that pull in mind.
TSMC says its Phoenix site has been in volume production since late 2024, and in March 2025 it raised its planned U.S. investment to 165 billion dollars, adding three more fabs and two advanced packaging plants. Intel's Fab 52 on its Ocotillo campus in Chandler began high volume production on the Intel 18A process in 2025. Amkor broke ground in Peoria in October 2025 on a packaging and test campus it now values at 7 billion dollars. In 2023 TSMC itself delayed production in Arizona, saying it could not find enough workers skilled in installing fab equipment.
Fabs and their equipment suppliers buy a lot of tight tolerance machined parts, weldments and ultra clean components. For an aerospace buyer that has three effects:
- Shops that serve both markets may book capacity months ahead around fab construction and tool install schedules. Ask for a committed date, not an estimate.
- Semiconductor cleanliness and aerospace cleanliness are different specifications. A shop that cleans to a fab standard still needs your precision cleaning callout and verification method.
- A shop's ISO 9001 certificate earned for semiconductor work does not cover AS9100 requirements such as first article inspection and counterfeit prevention. See AS9100 vs ISO 9001 suppliers.
Heat and dust: shipping and storing hardware in Arizona
Arizona's risks are heat and dust rather than humidity, and both affect measurement, packaging and storage.
- Heat. The National Weather Service lists 21 days a year at 110 degrees F or hotter in Phoenix on the 1991 to 2020 normals, and 70 such days in 2024. A closed trailer or uncooled storage room runs hotter than the air. Adhesives, sealants, elastomers, prepreg and coated parts with temperature limits need cooled transport or a defined storage range on the PO.
- Measurement. Dimensions are specified at the 20 degrees C reference temperature. A part inspected warm will read large, so require final inspection in a controlled room and soak time before receiving inspection.
- Dust. The NWS monsoon season runs June 15 to September 30, and dust storms are common along the I-10 corridor between Phoenix and Tucson. Fine dust gets into open fittings, bores and bearings. Cap ports, bag precision parts and specify sealed crates for anything with fluid passages or optical surfaces.
- UV. GSE, hoses, labels and seals stored outdoors degrade faster. Call out UV rated materials and covered storage where it matters.
For packaging options, see crating and packaging and shipping flight hardware.
I-10 and freight between Phoenix and Tucson
I-10 is the main truck route between the two metros, so most Arizona parts move on it at some point. Plan for construction and summer weather on that stretch.
ADOT is widening about 26 miles of I-10 south of Phoenix through the Gila River Indian Community in the Wild Horse Pass Corridor project, with phases running through late 2029. Summer dust storms can drop visibility to near zero on the same stretch. A run between the two metros is short on a good day and unpredictable on a monsoon afternoon. For critical parts, ask for morning delivery windows in summer and confirm receiving hours at secured plants. West of Phoenix, I-10 continues toward Southern California, which matters when a special process or a second source sits in the Los Angeles basin; see our California page.
Standards and flow-downs Arizona buyers apply
Because Arizona work is mostly defense, expect the full DoD set of clauses on top of the aerospace quality system.
| Requirement | What it covers | Typical Arizona callout |
|---|---|---|
| AS9100 | Aerospace quality management system | Required for production, engine and missile parts |
| AS9102 | First article inspection | New part numbers, revisions and source changes on long running production |
| DFARS 252.225-7009 | Specialty metals melted in qualifying countries | Missile, rotorcraft and launch vehicle titanium, steel and nickel alloys |
| DFARS 252.246-7007 and 7008 | Counterfeit electronic part detection and sourcing | Sustainment buys, obsolete electronics, reclaimed assemblies |
| ITAR | Export controlled defense articles and technical data | Nearly all missile, interceptor and military rotorcraft drawings |
| DFARS 252.204-7012 and CMMC | Protection of controlled unclassified information | Any supplier handling program technical data |
More detail: DFARS specialty metals, AS9102 first article inspection and defense contractors. Controlled drawings never go through a web form; see controlled programs.

Questions
Can I buy parts from the Davis-Monthan boneyard for my program?
Not directly in most cases. The 309th AMARG reclaims parts to support military fleets, and parts the services no longer need go to DLA Disposition Services, which decides whether they are sold intact or destroyed and sold as scrap based on demilitarization and flight safety screening. If you find a reclaimed or surplus part on the open market, treat it as an obsolete part purchase: require chain of custody, condition records and testing, or consider remaking it to a current drawing.
Do Arizona missile and rotorcraft parts need DFARS specialty metals compliance?
Usually, yes. DoD prime contracts for missiles, aircraft and launch vehicles normally carry DFARS 252.225-7009, which restricts where specialty metals such as titanium, many steels and nickel alloys were melted. The requirement flows from the prime to every supplier making parts from those metals. Include the clause in your request so the material is bought with compliant mill certs from the start, rather than discovering the problem at receiving inspection.
How does Arizona heat affect inspection and storage of machined parts?
Dimensions are defined at 20 degrees C, and aluminum grows about 23 micrometers per meter for each degree above that. A 500 mm aluminum part measured 15 degrees warm reads roughly 0.17 mm long. Require final inspection in a controlled room and let parts soak before receiving inspection. For storage, specify maximum temperatures for adhesives, seals, coated parts and composite materials, since trailers and warehouses can run far hotter than the outdoor reading.
Will semiconductor fab demand make it harder to get aerospace machining in Phoenix?
It can tighten capacity. TSMC, Intel and Amkor are building or expanding fabs and packaging plants in the Phoenix area, and their equipment suppliers buy many precision machined and welded parts from the same shop base and labor pool. Ask for a committed delivery date, check that the shop's quality system is AS9100 rather than only ISO 9001, and consider splitting work across shops or sourcing outside the metro when capacity is tight.
Can you handle ITAR drawings for a Tucson or Chandler defense program?
Yes, but never through the website. Send the non-controlled details first: material, size, quantity, finish, quality requirements and need date. Every supplier signs a flow-down NDA before seeing customer files, controlled technical data moves only by secure transfer to US persons, and suppliers do not learn the end customer unless you approve it. Our confidentiality and controlled programs pages explain each step.
Does monsoon season matter for Arizona deliveries?
Yes, for timing and packaging. The NWS defines the Arizona monsoon as June 15 to September 30, and afternoon dust storms and thunderstorms can close or slow I-10 between Phoenix and Tucson and halt flights at Sky Harbor. Ask for morning delivery windows on critical parts, cap open ports and bores, and use sealed crates for precision or fluid hardware moving during those months.
