Large-Caliber Munitions
Artillery, tank, and mortar rounds - 155mm, 120mm, 105mm, and 81mm. Complete rounds, projectiles, fuzes, primers, and propellant charges moving across US primes, allied MoDs, and licensed program offices.

Four peer practices, one program counterparty. Each runs independently and reports into a single program lead, so defense engagements that would normally require four vendors - or four conversations - route through one door.
We place products into defense primes, defense-tech companies, federal programs, and allied channels - opening accounts our partners could not otherwise reach, from prime subcontracts to FMS pursuits.
Most companies build well and sell narrowly. We carry their capability into rooms they don't get into - program offices, prime sourcing teams, allied attaché channels - and structure the agreements that turn pursuit into PO.
From critical minerals and refractory metals to energetics, propellants, and finished assemblies, we procure to spec, screen for compliance, and orchestrate the freight that gets material to the program line on schedule.
Material risk is program risk. We hold supplier scorecards across domestic and allied sources, verify country-of-melt and chain of custody, and run controlled-flow logistics for ITAR and DFARS material end-to-end.
A bidirectional gateway for allied defense markets - placing American capability abroad, bringing allied capability into the US, and structuring cross-border deals through vetted partners.
We work the seams between the US industrial base and allied markets - NATO, Indo-Pacific, Gulf - building the rep network, licensing, and finance structures that make cross-border programs actually move.
When a program needs hardware built to spec, we open a vetted US partner network - additive, subtractive, casting, forging, PM-HIP - and act as the single counterparty across the build.
We don't run shops. We access them. We select the right partner for the part, manage tooling and process qualification, and ship to spec with documentation that holds up under DCMA scrutiny - without the buyer having to hunt a dozen quotes themselves.
Each practice runs across the sectors that define the modern defense industrial base - from large-caliber munitions and energetics to critical minerals, unmanned systems, and suppressors. What follows is the map of where United Supply operates, and where we're active today.
These are the sectors that define our current book of work. Each sector has an assigned practice lead, a partner roster, and an active pipeline. If yours isn't listed, it's on request.
Artillery, tank, and mortar rounds - 155mm, 120mm, 105mm, and 81mm. Complete rounds, projectiles, fuzes, primers, and propellant charges moving across US primes, allied MoDs, and licensed program offices.
Small arms and medium-caliber ammunition - 5.56, 7.62, .50 BMG, 25mm, and 40mm. Finished rounds, brass, links, and components for DoD, federal LE, and allied end users.
High-explosive fills, propellants, and precursor chemistry - TNT, RDX, HMX, C4, and IMX formulations. Raw and formulated energetics feeding US and allied munitions programs, sourced through licensed producers and controlled distribution.
Tungsten, tantalum, niobium, rare earths, titanium, aluminum-lithium, magnesium, ferrosilicon, and specialty alloys. Sourced from allied and domestic producers to insulate primes and defense-tech OEMs from PRC-dominated supply chains.
Unmanned aerial systems and the counter-UAS layer that defends against them. Airframes, propulsion, batteries, ISR payloads, RF and kinetic C-UAS effectors - sourced and built with qualified US partners when a program needs hardware fast.
Complete suppressors, cans, muzzle devices, and small-arms accessories for federal LE, DoD end users, and allied contracts. Includes OEM manufacturing partnerships and export-controlled distribution.
We'll route you to the practice lead within one business day.
