Top Vendors by Category (via FPDS / FPDSplus)

TOP OTSBs (DOD, last 5 years)

Over the past five fiscal years, the Department of Defense (DoD) has awarded the highest federal action obligations in Engineering Services (NAICS) to a select group of Other Than Small Businesses (OTSBs). Leading the pack is HII Technical Solutions Corporation, which received over $134 million, making it the top-performing vendor by a significant margin. Following HII is Accenture Federal Services, with nearly $99 million in obligations—solidifying its position as a key player, though still considerably behind HII.

After these two giants, the distribution drops sharply. BlueWater Federal Solutions, MDPAC JV, and FSB – POND Joint Venture each secured between $19 million and $29 million, illustrating the steep curve in funding distribution. These vendors, especially joint ventures, likely offer specialized capabilities or strategic partnerships that attract mid-tier contract opportunities from the DoD.

The remainder of the top 20 vendors received significantly less, with awards ranging from around $4 million down to under $1 million. Notable names like HDR WTNA JV and SHERMCO Industries fall into this category, suggesting a highly concentrated market where a few firms dominate and the rest compete for smaller, specialized contracts.

Overall, the data highlights a top-heavy landscape where a small number of vendors consistently capture the bulk of federal obligations. Success in this space appears to be driven by scale, strategic partnerships, and the ability to meet complex defense-related engineering needs.

TOP VENDORS with $10M to $50M contracts at DOD

Over the past five fiscal years, the Department of Defense (DoD) has awarded a significant volume of mid-sized prime contracts—valued between $10 million and $50 million—within the Engineering Services NAICS code. Among the top-performing vendors in this category, Booz Allen Hamilton Inc. stands out as the clear leader, accumulating over $1.2 billion in total obligations. This suggests Booz Allen's deep integration in the DoD's engineering operations, likely supported by its extensive experience and broad capabilities.

Close behind, Lockheed Martin Corporation and Peraton Inc. have each secured over $680 million in total contract value, demonstrating strong, consistent performance across numerous contracts. These vendors have firmly positioned themselves as go-to providers for the DoD in delivering complex engineering services through multiple mid-sized engagements.

Mid-tier leaders such as SAIC (Science Applications International Corporation) and Northrop Grumman Systems have also garnered between $550 million and $590 million, with another Northrop division and SERCO Inc. following closely behind. These companies have successfully scaled their operations through strategic bidding, solidifying their roles in DoD’s vendor ecosystem.

Firms like Raytheon, BAE Systems, The Boeing Company, and General Dynamics Information Technology round out the list, each accumulating hundreds of millions in obligations. Though slightly lower in total volume, these vendors represent strong potential teaming partners for companies aiming to break into the DoD engineering space. Their ability to repeatedly win mid-sized contracts reflects reliability, technical capability, and strong government relationships—key traits for effective collaboration.

TOP SB VENDORS at DOD over the last five years

Over the last five years, Credence Dynamo Solutions LLC has emerged as the top-performing small business contractor for the DoD in engineering services, securing more than $195 million in total action obligations. This places it significantly ahead of its peers and demonstrates its capacity to handle high-value defense contracts.

In second place is Tekla Research Inc., with $182 million in obligations, followed closely by Strategic Alliance Solutions LLC, which captured around $148 million. These vendors form the leading tier of small businesses consistently winning substantial engineering contracts with the DoD, each exceeding the $100 million mark in total obligations.

Other notable firms in the top ten include EA-Baker JV, Oceanetics Inc., and Green Expert Technology Inc., all receiving between $110 million and $120 million. These companies reflect a strong mid-tier presence, indicating both reliability and specialization in serving complex DoD engineering needs.

Rounding out the top 20 are vendors such as Pelatron Technologies, EH5 Technologies Corp, and Marine Systems Corporation, each with totals in the $90–$100 million range. Although smaller in comparison to the top five, these businesses have consistently secured contracts, showcasing the depth and competitiveness of the DoD’s small business ecosystem in engineering services.
