A General Dynamics subsidiary doing $107 billion in federal IT work
General Dynamics Information Technology, Inc. (GDIT, UEI SMNWM6HN79X5) is headquartered at 3211 Jermantown Road, Fairfax, Virginia, and is listed in USASpending as a subsidiary of both General Dynamics Corp — the publicly traded defense giant — and WICO Limited, a corporate holding entity. Unlike the SDVOSB resellers and staffing pass-throughs covered elsewhere in this series, GDIT is a large-business prime contractor operating across all three of the primary NAICS codes tracked in the federal IT contractor landscape: 541511 (Custom Computer Programming), 541512 (Computer Systems Design), and 541519 (Other Computer Related Services).
Its top 15 awards span the Department of State ($2.77B combined), the Department of Health and Human Services ($2.87B combined), the General Services Administration ($1.42B combined), the Department of Defense ($2.97B combined), and the Department of Homeland Security ($1.25B combined) — and these are just the largest individual orders. The full agency breakdown, which has more than 15 entries, puts DoD alone at $54.2 billion, dwarfing every other customer.
Three contracts that reveal three completely different supply chains
GDIT's largest individual contracts with disclosed subaward data are not variations on a theme — they are fundamentally different operations. The same company name covers a State Department global security supply chain, an HHS cloud-software procurement vehicle, and a Navy shipboard C5ISR engineering program. Each has its own dominant subcontractor ecosystem with almost no overlap between them.
This is the largest subaward ecosystem by far — and the one most different from "IT." The vast majority of its 3,517 subawards are for physical security products and supply-chain fulfillment: cameras, scanners, access-control equipment, cabling, and hardware shipped to State Department embassies and diplomatic facilities worldwide. A single subcontractor, WESCO Distribution, Inc., received $1.677 billion across 284 subaward transactions — more than the prime contract's own obligated total, reflecting subaward draw against the full base+options ceiling.
| Subcontractor | Subaward Total | Transactions |
|---|---|---|
| WESCO Distribution, Inc. — industrial/electrical distributor | $1,677,634,971 | 284 |
| Nomad Solutions LLC — IT services | $95,768,825 | 21 |

| Top 10 subcontractors shown | ~$2.03B |
The WESCO finding. WESCO Distribution, Inc. is a Pittsburgh-based, publicly traded industrial and electrical distributor (NYSE: WCC) with roughly $22 billion in annual revenue — and its own direct federal prime contracts total just a few million dollars. Yet it received $1.677 billion as a subcontractor to GDIT on this single State Department program. This is the same "prime-as-pass-through, subcontractor-as-real-operator" pattern seen with Take2 and Booz Allen — just in the physical-security supply chain world rather than IT staffing.
This contract is the opposite of the State Dept program: it's pure cloud and SaaS procurement, with GDIT acting as a procurement-and-integration layer that passes a large majority of the contract value through to commercial cloud providers. Amazon Web Services alone received $400.6 million across two entity-name registrations (73% of all subaward dollars on this contract). Carahsoft — which appears elsewhere in this series as a reseller of AWS and Microsoft products — adds another $102.0M. The majority of the remaining subaward value goes to Snowflake ($40.5M), CDW Government ($37.5M), and Microsoft ($19.6M).
| Subcontractor | Subaward Total | Transactions |
|---|---|---|
| Amazon Web Services, Inc. (both registrations combined) | $400,573,213 | 20 |
| Carahsoft Technology Solutions (both registrations combined) | $102,044,546 | 129 |
| Snowflake Inc. — cloud data platform | $40,458,874 | 33 |
| CDW Government LLC — IT products reseller | $37,512,268 | 71 |
| Microsoft Corporation | $19,576,081 | 13 |
| Equinix, Inc. — data center colocation | $12,598,861 | 7 |
| Blue Tech Inc. — IT services | $6,785,659 | — |
| Wholepoint Systems, LLC | $6,696,750 | — |
| Top 8 subcontractors shown | ~$626.2M of $657.5M total |
This program supports Navy ship and aircraft command, control, communications, computers, intelligence, surveillance, and reconnaissance (C5ISR) systems — genuine defense-systems engineering, not software resale. Its subcontractors reflect that: Prism Maritime ($138M, ship systems), Delphinus Engineering ($55.9M, marine engineering), Serco Inc ($20.8M, defense services), HII Fleet Support Group, Tecnico Corporation. Notably, this $837.9M contract drew only one offer despite being coded as "full and open competition" — a common pattern on highly specialized defense programs where incumbent knowledge creates a practical sole-source situation even without formal set-aside status.
| Subcontractor | Subaward Total | Transactions |
|---|---|---|
| Prism Maritime, Inc. — ship systems integration | $138,029,734 | 2 |
| Delphinus Engineering, Inc. — marine engineering | $55,929,574 | 4 |
| Serco Inc — defense systems services | $20,750,101 | 3 |
| HII Fleet Support Group LLC — naval services | $6,496,746 | — |
| Tidewater Marine Electric LLC | $3,229,682 | — |
| Advanced Integrated Technologies, LLC | $2,994,548 | — |
| Tecnico Corporation — ship repair/maintenance | $2,994,548 | — |
| Top 7 subcontractors shown | ~$230.4M of $263.9M total |
One company name, three distinct supply chains — and the recurring question
Looking across GDIT's three disclosed-subaward contracts reveals a pattern distinct from the SDVOSB-reseller and staffing-pass-through profiles covered elsewhere in this series: GDIT is doing genuinely different things on different contracts, and its subcontractor ecosystems reflect actual operational substance — physical security distributors for embassy supply chains, cloud-software vendors for cloud-procurement contracts, and defense engineers for shipboard C5ISR programs.
That said, the HHS Cloud Products & Tools contract raises the same structural question found across multiple companies in this series: 73% of a $902M prime contract's subaward dollars went directly to Amazon Web Services — a company whose own federal sales capability (through AWS GovCloud and direct agreements) would allow agencies to purchase the same services without a prime contractor intermediary. Whether GDIT's integration, management, and procurement layer on this contract justifies a prime-contract position for essentially a commercial cloud procurement is a question the contract record alone can't answer — but it's worth asking, as it was worth asking for the SDVOSB-held SEWP V cloud contracts documented earlier in this series.
WESCO Distribution, Inc. — $1.677 billion as a subcontractor to GDIT on the State Department's Global Security Engineering contract, yet only a few million dollars in its own federal prime-contract history. This mirrors the Take2 Consulting finding ($512 million as a subcontractor, $1,000 as a prime) in a completely different industry segment, and suggests the "prime-as-coordinator, subcontractor-as-real-operator" structure isn't specific to IT staffing — it's a general feature of how large federal programs are actually delivered, across sectors from cloud software to embassy security equipment to naval engineering.
What we are not claiming: GDIT is a large, long-established defense and IT contractor with genuine capabilities across multiple domains. None of the subaward relationships documented here suggests any improper arrangement — prime contractors routinely and legitimately engage specialized subcontractors for supply chain fulfillment, commercial software procurement, and engineering disciplines outside their own core competency. The C5ISR contract's single-offer outcome is common on specialized defense programs and is not, by itself, evidence of any problem. What this report adds is visibility into the subaward layer — the actual economic structure beneath the "GDIT" headline on three of its largest contracts — and that visibility is useful for anyone trying to understand where federal IT and defense dollars actually go, and why "who holds the prime contract" is frequently a different question from "who does the work and who gets the money."
Scale, complexity, and the limits of a company name as a unit of analysis
GDIT's $107+ billion federal footprint is too large and too diverse to reduce to a single narrative. DoD ($54.2B) alone dwarfs most companies in this entire series combined. The company's contracts span logistics support, telecommunications infrastructure, cloud services, engineering design, research and development, and physical security supply chains — each with its own subcontractor ecosystem, competitive dynamics, and economic model.
GDIT's three largest subaward-disclosure contracts — $2.47B in State Dept supply chain (73% to WESCO Distribution), $657M in HHS cloud procurement (73% to Amazon Web Services and Carahsoft combined), and $264M in Navy C5ISR engineering — show the same structural feature documented across this entire series at every scale: the company name on a federal contract is not necessarily the company doing the majority of the economic work. At GDIT's scale, that observation applies to $1.677 billion going to an industrial distributor and $400 million going to a cloud hyperscaler — entities whose own direct federal footprint is a fraction of what they receive through a prime.
