Cobb County
Every one of them was built here
Air Force Plant 6 is a government-owned, contractor-operated aerospace facility, owned by the US Air Force and operated by Lockheed Martin Aeronautics, and its coordinate reverse-geocodes to Cobb County 2.33 miles from the place centroid.
The claim attached to it is unusually clean for a secondary source, because it is a claim about all of something rather than a ranking. Every production C-130 Hercules ever built — more than 2,600 delivered — has been produced at Marietta since 1954, on a site with seventy-five years of Lockheed operation behind it.
That is a count and a start date rather than a superlative, which is why this page repeats it. Nothing here re-verifies it, and nothing here extends it into a claim about current strength, current workload or what the plant is building now.
An airframe plant is a place freight goes, not a place it comes from
That distinction has a consequence this research had not met before, and it is the useful part for anyone with a truck. What Air Force Plant 6 finishes, it flies out.
So the site is a freight destination and almost not a freight origin. Everything arrives by road — assemblies, tooling, consumables, the enormous quantity of ordinary material a plant of that age consumes — and the one thing that would otherwise dominate the outbound lane leaves under its own power from a runway. Most industrial nodes in this list are the other way round: a quarry or a mill exists to put tonnage onto a road, and Lockheed Martin Aeronautics does not.
What follows for a fleet is a shape rather than a number. Inbound-dominant work means deadhead on the return leg unless somebody has arranged a backhaul, and it means the trucks serving it are more often flatbeds, box trucks and step-frames carrying awkward freight than they are dump bodies carrying tonnage. None of that was measured here; it follows from what the plant is, and it is offered as a reading rather than a figure.
Georgia weight law
Cobb is metropolitan, so the variance was never on the table
Those inbound loads run under the plain ceiling, because the one Georgia concession that could lift it is switched off in this county.
O.C.G.A. § 32-6-26 puts the general gross limit at 80,000 lb on state and US highways. HB 189 (2023), as amended by HB 164 (2025), lets forest-products and agricultural loads run ten per cent over — 88,000 lb on five axles — within 150 miles of origin, on state and local roads only, and outside the air-quality non-attainment counties. HB 164 removed the 1 July 2025 sunset, so the figure is permanent.
Cobb County is one of the thirteen those conditions exclude, so the allowance is geographically unavailable here whatever is on the truck. In practice it would rarely have mattered at an aerospace plant, where the awkward freight is oversize rather than overweight — but the two are governed separately and this page is only speaking to the weight half.
The inversion still applies on the way out of the metro. Georgia state and US highways take a qualifying load at 84,000 lb including tolerances while the interstate caps at 80,000 plus the federal bridge formula, so the bigger road is the tighter one. County roads run to 56,000 lb unless the truck is making a pickup or delivery on that road.

Georgia paperwork
We need a title — unless the truck never had one
Those rules decide the load. This one decides the sale, and it is a single sentence.
Everything after that is a fix rather than a taxonomy. A lost title is a counter transaction at a tag office — a driver’s licence, the year, make and model, the vehicle identity number, a fee of $18, printed on the spot in about forty-five minutes depending on the line. Where no title exists, the bonded route runs through a surety company, an application with a sales document, a police inspection form confirming the vehicle is not stolen, then the tag office.
Georgia brands salvage by a total-loss formula rather than a fixed percentage, weighing repair cost against actual cash value with salvage value factored in. Under O.C.G.A. § 40-3-37 the commissioner inspects a salvaged or rebuilt vehicle before any title issues, and the rebuild has to have been done in Georgia.
Where there is a lien on it, the release is the slow part. Georgia files liens electronically and a lienholder on that programme cannot issue a paper release; only lienholders holding liens on fewer than five Georgia-titled vehicles may use the paper certificate.
Emissions is still not a step even though Cobb County is one of the thirteen: diesel vehicles are exempt regardless of age or weight, and anything above 8,500 lb rated gross is outside the programme entirely.

What we buy here
None of that changes what we buy. Flatbeds, step-frames and lowboys on the inbound work a plant like Air Force Plant 6 generates. Day cabs and box trucks on the supplier and logistics traffic around it. Dump trucks and straight trucks on the construction that follows any large employer in Cobb County, plus rollbacks, service bodies, and the work trucks and pickups that go out with a crew.
Whatever you drive, the offer doesn’t change. We buy all of them.
We buy complete trucks. If the engine, transmission, doors, rear ends, drive shafts, wheels or anything under the hood have been removed, we can’t buy it. Small things — a missing bumper — are fine.
Straight answers
The questions we get asked in Marietta
- Does it have to run?No. It does have to be complete — if the engine, transmission, doors, rear ends, drive shafts, wheels or anything under the hood have been removed, we can’t buy it. Rust is not a disqualifier.
- The engine is out of it. Is that different?Yes, and that is the line. A tired engine is fine. An engine that has been pulled and sold means we can’t buy the truck.
- What about the title?We need one unless the truck is old enough that it never had one. A lost title has a counter replacement; where none exists there is a bonded route. Neither stops a sale.
- It ran mostly empty one way. Does that count against it?No. Inbound-dominant work means deadhead return legs, and the odometer reflects that rather than the load. We buy on what the truck is, not on how its miles were earned.
- Is Cobb County in the emissions programme?Cobb is one of the thirteen counties Georgia’s programme covers. It does not reach a diesel truck, and nothing rated above 8,500 lb is inside it at all, so it is not a step in selling one.
- Do you actually come out to Marietta?Yes, and it is a short run. We also buy remotely and arrange the tow if that suits you better, or come to you and tow it, and you can bring it to us.
Why people call
That last one is the question under most of the calls out of Cobb County, and what sits behind it has nothing to do with Lockheed Martin Aeronautics or with 2,600 airframes.
Retiring. A medical that went the wrong way. A hauling contract that ended and left one machine too many in the yard. Sometimes it is only that the truck has been parked since the last load went out, and every month it sits is another month of insurance on something that isn’t turning a wheel.
Most of those aren’t happy reasons, and we don’t treat them like they are. Somebody wants a straight answer and the truck gone by the end of the week. That’s what we’re here for.
