Oshkosh Defense will manufacture large military drones under a partnership with Silicon Valley startup Grid Aero, the first aircraft in the history of a Wisconsin company better known for trucks that stay on the ground. The deal, announced Monday, is a small piece of a much larger bet: that the Pentagon can rebuild a domestic industrial base for uncrewed aircraft by borrowing the methods of vehicle production rather than the methods of aerospace.
The technical reality is that most large drones are built the way aircraft have always been built, in small numbers, by specialist firms, from composite materials that demand careful handling and slow cure times. Grid Aero’s Lifter is different. It is built from metal.
What the Lifter Actually Is
Grid Aero was founded in 2024 and developed the Lifter, an autonomous aircraft with modular payload capacity that the company describes as a “pickup truck of the skies.” It falls into the Group 4 or Group 5 category of unmanned aerial systems, classifications covering aircraft that weigh more than 1,320 pounds.
Co-founder and CEO Arthur Dubois said the design “borrows as much from military trucks as from traditional aircraft.” He described it as “simple, rugged, piston-powered, and made from ubiquitous materials.” That last phrase is the detail that matters for manufacturing. Composites are neither ubiquitous nor forgiving. Metal is both, at least if you already own the presses, the jigs and the people who know how to run them.
Oshkosh does. Logan Jones, the company’s chief growth officer, put the cultural gap plainly in an interview with Defense News: “We do things that like gravity and stay on the ground.” He called the partnership “a very nice fit for us.”
Why Metal Beats Composites at Scale
Oshkosh was drawn to Grid Aero in part because the Lifter uses metal construction rather than composite materials, which aligns with Oshkosh’s existing manufacturing capabilities. The company’s pitch is not that metal flies better. It is that metal builds faster, and that the bottleneck in military drone production has moved from design to output.
Dubois made the same point from the startup’s side. “They build vehicles by the thousands, and that is the rate we need,” he said in an email to Defense News. “Their lines are also built for variety. A single Oshkosh line can build many variants of a vehicle, each set up for a different mission, without slowing down. Lifter works the same way.”
That flexibility is not a small thing in a machine billed as modular. A production line that can switch between mission variants without stopping is the difference between a drone fleet configured for one fight and a fleet that can be reconfigured as the fight changes.
A Subcontractor That Behaves Like a Partner
On paper, Oshkosh is a subcontractor. Jones said the companies describe the arrangement as a partnership because Oshkosh is helping Grid Aero reconfigure the Lifter aircraft “to ensure that manufacturability is at the heart of their design and strategy from day one, not an afterthought.”
That is the most consequential sentence in the announcement. Most defence programmes discover their production problems after the design is frozen, when a change means re-certifying a wing or re-tooling a fuselage. Bringing the factory into the design phase inverts that order. The aircraft is being bent to the line, not the other way round.
For Grid Aero, the choice came down to Oshkosh’s experience. Dubois said the company’s extensive defence manufacturing record helped solidify the decision to work together.
The Arsenal of Freedom Connection
Jones said the partnership grew out of the Defense Department’s Arsenal of Freedom campaign, which aims to expand the domestic industrial base. Grid Aero needed a partner to help scale production. Oshkosh was looking to manufacture something with long-term potential.
“We looked where both the market was growing, and where the technology class would benefit from scale,” Jones said, explaining why the company has been exploring unmanned systems.
The companies plan to build thousands of Lifter aircraft for the Defense Department and commercial customers. Initially, Grid Aero will conduct low-rate production while Oshkosh establishes a production line. That sequence is standard for defence aviation, and it is also where programmes tend to stall: low-rate production is easy to fund and hard to grow out of.
What It Means for the Industrial Base
The strategic logic runs against the grain of how the Pentagon has bought aircraft for decades. Large drones have largely come from a handful of primes with specialised composite supply chains, and those chains are thin. A vehicle manufacturer that stamps, welds and assembles by the thousand offers a different kind of capacity, one measured in units per month rather than units per year.
Whether that capacity translates into aircraft the services will buy is a separate question, and not one the announcement answers. What it does show is a template: take an existing design built from ordinary materials, hand it to a factory that already knows how to make thousands of ordinary things, and let the factory shape the design before the first one ships.
The first test of the template is the low-rate production phase, which Grid Aero will run while Oshkosh stands up its line.
