About Millennium Systems Services, Inc.
Millennium Systems Services, Inc., doing business as Mssi, is a SBA Certified Women-Owned Small Business based in Huntsville, Alabama, that delivers aviation logistics support, program management, engineering staffing, and technical services to the Department of Defense and federal civilian agencies as a prime contractor (100% of recent awards). Mssi is an Asian-Pacific American and minority-owned enterprise competing full-and-open across federal schedules and army-specific vehicles rather than set-aside-reserved programs.
Mssi's customer concentration is heavily weighted to Army aviation platforms. The top five funding entities account for 77% of recent awards by count but 97% by combined potential value, creating a pronounced skew toward large PEO Aviation deliverables. The Department of the Army Acquisition Support Center's PEO Aviation represents 2 awards with $220.2 million in combined potential value — the single largest concentration point — followed by the Department of the Army Materiel Command's Aviation and Missile Life Cycle Management Command (33 awards, $105.3 million potential), the GSA Federal Acquisition Service (3 awards, $93.7 million potential), and the Defense Logistics Agency Document Services (12 awards, $3.4 million potential). The Air Force Air Education and Training Command places 24 awards but with only $1.3 million in combined potential value, signaling high-volume, low-dollar activity distinct from the Army's large program structure.
Mssi's three highest-impact parent vehicles are the Multiple Award Schedule (9 task orders, $390.6 million combined potential value), the AMCOM EXPRESS indefinite delivery contract (10 task orders, $126.1 million potential), and an unnamed Indefinite Delivery Contract W58RGZ07G0005 (12 task orders, $2.4 million potential). The December 2023 MAS Federal Supply Schedule contract runs through March 28, 2028 with a $90 million ceiling and covers five special item numbers spanning IT, management consulting, logistics, and training services. A September 2023 BPA under MAS for express logistics professional services expires January 22, 2028. The flagship award is a December 2025 BPA call with PEO Aviation for Apache Logistics Support Services, valued at $194 million, placed under the MAS and running through June 2031. Mssi also holds a November 2021 Basic Ordering Agreement with Army Sustainment Command through July 2027 for Eagle Logistics Support Services, with zero-dollar ceiling but operational task-order authority, and a December 2023 BOA refresh on the same contract.
Mssi's capability portfolio centers on aviation sustainment, logistics support, program management, engineering staffing, and technical specialists. The company holds AS9100 Rev D and ISO 9001:2015 certifications, critical for defense aerospace work. GSA Schedule labor spans 40 categories across administrative support, entry-level through senior engineering, and program management, with hourly rates ranging from $45.40 for administrative support to $237.89 for senior program managers; no security-cleared positions are offered. Work is performed in Huntsville, Alabama, supporting PEO Aviation and Army field operations. The NAICS concentration runs across Facilities Support Services (25 awards), Other Support Activities for Air Transportation (17 awards), and Other Computer Related Services (11 awards), with PSC concentration in Radar Equipment, Support-Professional, and Support-Administrative categories.
Activity across the portfolio is sparse and episodic: one award in 2021, three in 2023, and one in 2025, with an early award dating to March 2003. The combined potential value across all 98 prime awards is $438.6 million, with $119 million obligated (27% realization rate). The large recent awards (PEO Aviation Apache contract and MAS schedule) represent late-stage activity and anchor the bulk of forward value; the source does not detail task-order trajectory that would signal growth or decline within those vehicles.
SCI-reportable service-contract activity is minimal: three records across FY2022–FY2024, all as named subcontractors under other primes, with 1.9 FTEs reported in FY2022 and 0.7 FTEs in FY2024. This reflects that Mssi's SCI footprint is a negligible slice of its prime federal services revenue, which flows primarily through the large GSA MAS and Army vehicle awards documented in the prime portfolio.
