About the company
One Defense LLC, a woman-owned small business based in Arlington, Virginia, operates as a subcontractor (67% of recent awards) on federal management consulting and disaster support programs, with limited prime footprint and a concentrated customer base across FEMA, Army Training and Doctrine Command, and DARPA. The vendor is a for-profit Subchapter S corporation structured as a woman-owned business; recent work clusters under NAICS 541611 (Administrative Management and General Management Consulting Services) and PSC categories for management support and professional services.
One Defense's award portfolio is thin and heavily sub-weighted. Total federal awards number six across a six-year window (2018–2024), with combined potential value of $315 thousand and combined obligated dollars of $794 thousand — obligated amounts exceed potential value, indicating scope expansion or rate adjustments on executed work. The vendor operates predominantly as a named subcontractor to Guidehouse and The CNA Corporation; named prime awards account for only two of six total awards. FEMA dominates customer concentration by award count (three awards), while Army Training and Doctrine Command anchors potential value at $315 thousand across two prime awards. DARPA accounts for one award. All six awards place work under either the GSA Multiple Award Schedule (six task orders) or the DARPA Technical and Analytical Support Services vehicle (one task order).
Recent sub work includes a February 2024 award on Guidehouse's DARPA enterprise support services consulting task, and two prior sub awards under The CNA Corporation's GSA PSS contract for FEMA disaster support — a COVID-19 after-action review effort in Rhode Island (August 2021) and evaluation of FEMA's Public Assistance national delivery model (April 2022). Activity is sparse and flat; the vendor has landed one award per year from 2019 through 2022, then one in 2024, with no awards recorded in 2023. SCI-reportable service-contract activity shows minimal federal presence: the vendor delivered 0.4 FTEs in FY2022 and 0.2 FTEs in FY2024, both in subcontractor capacity on contracts above the $150 thousand reporting threshold. The tight FTE footprint and award dormancy from 2023–early 2024 signal either a shift to smaller or classified work, portfolio concentration on non-SCI vehicles, or declining federal engagement.
