Highbury Defense Group

What Highbury Defense Group does

Highbury Defense Group is a San Diego-based defense services contractor founded in 2013 and operating as a subsidiary of Accelint. The company delivers six core service lines: Technical and Systems Engineering, Cybersecurity Engineering, Foreign Military Sales (FMS), Maritime and Border Surveillance, Logistics and Training, and Program Management. Its customer base is centered on the US Department of Defense — across the Navy, Marines, Air Force, and Army — and the Department of State, with the FMS channel extending reach to more than 40 foreign governments.

The underlying delivery model is labor-based professional services: cleared personnel executing task orders, IDIQ contracts, and FMS case work in support of government program offices. The company does not appear to sell a standalone product or platform; revenue is generated through contract vehicles and time-and-materials or fixed-price engagements under federal procurement frameworks. The service portfolio is broader than a typical mid-tier federal contractor, with cybersecurity and maritime surveillance supplementing traditional program-management and logistics work.

The workforce is approximately 140 employees, with 85% holding ten-plus years and 40% holding twenty-plus years of defense industry experience, and over 60% drawn from former military ranks. This experience density functions as the company's primary execution asset — security clearances, FMS Trusted Agent familiarity, and accumulated past-performance dossiers are the assets that qualify Highbury for bid consideration. No financials, funding history, or specific contract values are disclosed in the available data.

Direct peers

• AMSEC: AMSEC, a subsidiary of Huntington Ingalls Industries, provides technical, engineering, and logistics support services to the US Navy — closely comparable to HDG's naval C4I, technical/systems engineering, and integrated logistics support offerings. Both firms operate in the San Diego Navy support market and compete for similar Navy program work.
• DCS Corporation: DCS provides engineering, technical, and programmatic support to DoD clients, including Army and Navy aviation/missile programs. It is comparable to HDG as a mid-tier, employee-owned (via trust) defense engineering services firm with similar service offerings and customer base.
• COLSA Corporation: COLSA provides defense, aerospace, and intelligence IT and engineering services to DoD customers. It is comparable to HDG in scale, mission focus, and emphasis on cleared technical talent supporting C4I and missile-defense-adjacent programs.
• Odyssey Systems Consulting Group: Odyssey is a mid-size DoD engineering services firm specializing in acquisition, program management, and systems engineering for Air Force and Navy programs. Its size, mission focus, and federal contracting model closely mirror HDG's positioning as a trusted-agent technical services provider.
• Systems Planning and Analysis (SPA): SPA provides analytical and engineering support to DoD and federal civilian clients, with a strong Navy and maritime focus. It is directly comparable to HDG in terms of mid-size, technical-services-led defense contractor profile and similar program management and FMS-adjacent capabilities.

Broad incumbents

• Booz Allen Hamilton: Booz Allen Hamilton is a large management and technology consulting firm with a substantial Navy and DoD practice covering C4I, cyber, and FMS support. It is a broad incumbent peer that competes with HDG for technical-services task orders but operates across many federal and commercial segments.
• Leidos: Leidos is a large defense and IT services prime contractor serving Navy, DoD, intelligence, and federal civilian clients. It is a broad incumbent peer overlapping HDG's Navy C4I, FMS, and cybersecurity work but at materially larger scale.
• ManTech International: ManTech (now a Carlyle portfolio company) provides technology and engineering services to DoD, intelligence, and federal civilian clients, with strong Navy and cyber practices. It is a broad incumbent peer comparable to HDG in domain focus but at substantially larger scale.
• SAIC: SAIC is a large IT and engineering services prime for DoD and federal agencies, with substantial Navy, Marine Corps, and intelligence community work. It is a broad incumbent peer competing for many of the same re-competed task orders HDG targets.
• CACI International: CACI provides IT, engineering, and intelligence services to DoD and federal agencies, with a deep Navy and intelligence community footprint. It is a broad incumbent peer with overlapping C4I, cyber, and FMS-adjacent offerings.
