Jobs & Economy in Marietta
Marietta's economy runs through a genuinely large, real aeronautics manufacturing employer -- Lockheed Martin's Marietta plant -- alongside a broader, diversified set of Cobb County employers spanning healthcare, retail, and government. This is a meaningfully different employment profile than a bedroom-community satellite with no industry of its own.

Lockheed Martin's Marietta site employs more than 5,600 people across an 8-million-square-foot facility, building the C-130J Super Hercules (more than 2,700 C-130s delivered to 70+ countries all-time) and producing F-35 center-wing assemblies; the site also houses the Skunk Works division. Georgia's Lockheed Martin workforce grew more than 25% since 2019 (over 1,200 new jobs at Marietta alone), and the C-130J/F-35 programs together are cited as supporting more than 20,000 direct and indirect jobs across Georgia -- see the base record for full sourcing.
A diversified set of other Cobb County employers
Beyond Lockheed Martin, major Cobb County employers cited in 2026 coverage include WellStar Health System (the area's dominant healthcare employer, including WellStar Kennestone and WellStar Cobb hospitals), Cobb County Public Schools and county government, and Publix, alongside Fortune 500 companies with a Cobb County presence such as The Home Depot -- though The Home Depot's corporate headquarters sits in unincorporated Cobb County near Vinings/Atlanta rather than inside Marietta's city limits specifically, a distinction worth noting rather than assuming.
Real healthcare-sector employment alongside aerospace
WellStar Health System's significant local presence -- anchored by WellStar Kennestone Regional Medical Center in Marietta (see healthcare) -- makes healthcare a second genuine, large-scale employment sector in the immediate area, not just a downstream service industry riding on Lockheed Martin's payroll.
What this research pass could not confirm
A Marietta- or Cobb-County-specific unemployment rate was not confirmed with a precise, independently sourced 2026 figure this session. Georgia's statewide unemployment rate was cited around 3.4%-3.5% in 2026 reporting from the Georgia Department of Labor, but that describes the whole state, not Marietta or Cobb County specifically, and is disclosed here as a gap rather than substituted as a local number.
Key takeaways
- Lockheed Martin's Marietta plant employs more than 5,600 people across an 8-million-square-foot facility building the C-130J and F-35 center-wing assemblies -- a genuinely large, real anchor employer, not a marginal claim.
- Other significant Cobb County employers include WellStar Health System, Cobb County Public Schools/government, and Publix, plus a Fortune 500 presence including The Home Depot -- though Home Depot's HQ sits in unincorporated Cobb County near Vinings/Atlanta, not inside Marietta's city limits specifically.
- WellStar's substantial local healthcare presence, anchored by WellStar Kennestone in Marietta, makes healthcare a real second major employment sector in the area alongside aerospace manufacturing.
- A Marietta- or Cobb-County-specific unemployment rate was not confirmed this pass; Georgia's statewide rate was cited around 3.4%-3.5% in 2026, a state-level figure disclosed here as a gap rather than substituted for a local one.
