Aerospace companies in California: 347 sites, where they cluster, the listed companies and a territory plan

California has more aerospace manufacturing establishments than any other state, but half of them have fewer than 20 employees and eleven sites hold more than half the jobs. Plan a California territory around that split, not around the state total.

Market report6 min readPublished

California had 347 aerospace product and parts manufacturing establishments in 2023, employing 56,575 people on a $6.71 billion payroll (Census County Business Patterns): 18.25% of the US total and first among states. The Los Angeles metro holds 202 of them. Eleven establishments with 1,000 or more employees account for 54% of the jobs. Listed aerospace companies headquartered in the state include Teledyne, Ducommun, Rocket Lab, Karman and Joby Aviation.

  • 347 aerospace manufacturing establishments and 56,575 employees in 2023, first among states.
  • 173 establishments have fewer than 20 employees; the 11 with 1,000 or more employ 30,626 people.
  • The Los Angeles metro has 202 establishments; Riverside-San Bernardino and San Diego have 28 each.
  • Federal contracts coded to aerospace manufacturing and performed in California totaled $7.84 billion in fiscal 2025, fifth among states.
  • Kratos now lists Round Rock, Texas as its headquarters, and SpaceX announced a move to Starbase, Texas in late 2024.

California aerospace in Census data

US Census Bureau County Business Patterns (CBP) 2023, NAICS 3364 (Aerospace Product and Parts Manufacturing), State of California:

Measure (2023)California
Establishments347
Employees (week of March 12)56,575
Annual payroll$6,712,016,000
Average employees per establishment163.0
Average annual pay$118,639
Share of US establishments18.25% of 1,901
Rank among states by establishments1st

CBP counts establishments (single locations) with paid employees, so one company with three plants counts three times, and the self-employed aren't counted. California's economic development office (GO-Biz) cites a much larger figure, 110,000 aerospace jobs (from Lightcast), because its definition reaches beyond manufacturing.

Two markets in one state: many small shops, a few giant sites

Employees per establishmentEstablishmentsEmployees in that class
1 to 487146
5 to 939250
10 to 1947661
20 to 49501,594

100 to 249507,781
250 to 499165,737
500 to 999127,297
1,000 or more1130,626

The employee column comes from the same CBP state file, which publishes employment by size class for states, and it sums to the 56,575 total.

Half the establishments (173) have fewer than 20 employees and together employ about 1,000 people. At the other end, 11 sites hold 54% of the jobs. A seller can't treat those as one market: the small shops buy like small businesses, and the eleven buy through procurement departments and supplier portals.

What California makes

Industry (NAICS)EstablishmentsEmployees
Other aircraft parts and auxiliary equipment (336413)19815,396
Aircraft manufacturing (336411)50Not reported (high-noise)
Aircraft engines and engine parts (336412)492,364

Other missile and space vehicle parts (336419)193,232
Space vehicle propulsion units and parts (336415)106,496

"Not reported (high-noise)" means the Bureau published the figure but flagged it as moved by 5% or more by its confidentiality noise. The 50 space and missile establishments employ 17,395 people between them, more than the 198 aircraft parts makers. Beyond NAICS 3364, the state has 104 navigation and guidance instrument makers (NAICS 334511) with 18,327 employees and 2,221 machine shops, the second tier of the supply chain.

These eight metros hold 320 of the 347 establishments. Southern California is the core: Los Angeles alone has 58% of the state's establishments. San Jose's 13 sites average 326 employees, the Bay Area's space and eVTOL hardware. Kern County (the Bakersfield metro) includes Mojave, which Northrop Grumman's 10-K lists among its Aeronautics Systems sites, and Edwards Air Force Base. For the metro detail, see aerospace companies in Los Angeles and aerospace companies in San Diego.

Listed aerospace companies headquartered in California

Each company below was checked on the cover of its latest 10-K:

Company (ticker)HeadquartersFY2025 revenueEmployees
Teledyne Technologies (TDY)Thousand Oaks$6,115.4 millionAbout 15,800
Ducommun (DCO)Costa Mesa$824.7 million2,130
Rocket Lab (RKLB)Long Beach$601.8 million2,600+
Karman Holdings (KRMN)Huntington Beach$471.5 millionAbout 1,400
Joby Aviation (JOBY)Santa Cruz$53.4 million2,559 (31 Jan 2026)
Archer Aviation (ACHR)San Jose$0.3 million1,160 full-time plus 500 contingent

Teledyne's SEC industry code is navigation and guidance systems, and much of its business is instruments and imaging rather than aircraft. Two moves matter for anyone using an older list. Kratos Defense & Security Solutions still has a San Diego address on EDGAR, but its fiscal 2025 10-K gives Round Rock, Texas. And the Texas governor's office reports that SpaceX announced in late 2024 that it would move its headquarters from California to Starbase, Texas. Northrop Grumman, Boeing and Lockheed Martin run their largest California sites from headquarters in Virginia and Maryland.

Federal contracts performed in California

USAspending shows $7.84 billion of federal contract obligations in fiscal 2025 coded to aerospace manufacturing (NAICS 3364) with a California place of performance, fifth among states behind Texas, Arizona, Connecticut and Florida. The Department of Defense obligated $7.29 billion and NASA $488.2 million.

Recipient (as named in the federal record)FY2025 obligations
The Boeing Company$2,260.7 million
General Atomics Aeronautical Systems$1,039.4 million
Northrop Grumman Systems Corporation$529.3 million
AeroVironment$485.5 million
Northrop Grumman Systems Corp (second record)$444.4 million
Space Exploration Technologies (SpaceX)$411.9 million
General Atomics$325.5 million

Obligations are recorded where the contract places the work and exclude subcontracts.

Illustrative example. The seller and its numbers are invented; the counts are from Census data.

Coastline Quality (coastlinequality.example), a three-consultant AS9100 and ISO 9001 firm, wants a California book of business. It starts with the 85 establishments with 20 to 99 employees, where certification work is usually bought by one quality manager, and adds the eVTOL and space startups in the Bay Area, which need AS9100 before their first production contracts. At a 10% yearly win rate on 100 accounts and $28,000 per engagement, that's 10 projects and $280,000. Before writing, it confirms each target's certificate status in the IAQG's OASIS database and its entity status in bizfile. Bebop can build the target list from a plain-language description and explain each match.
