About the company
Millennium LLC, a service-disabled veteran-owned, minority-owned small business subsidiary of Markon LLC, serves as a prime contractor on defense engineering, systems integration, and red team training services to the Department of the Navy, Department of the Army, and Missile Defense Agency, holding positions on multiple-award IDIQs and blanket purchase agreements with a combined potential value exceeding $142 billion. The vendor competes predominantly full-and-open (94% of recent awards are prime contracts rather than sub awards), with no characteristic set-aside posture — all major recent procurements are unrestricted, allowing Millennium to compete across the broader federal market.
Millennium's capability portfolio centers on systems engineering, logistics, cybersecurity, red team training, test and evaluation services, and operational support. The flagship engagement is a $208.8 million cost-plus-fixed-fee delivery order issued by Naval Information Warfare Systems Command on September 9, 2021, under Seaport-NXG for systems engineering, logistics, and cybersecurity services supporting the PMW 240 Sea Warrior Program and PMW 250 Enterprise Systems and Services Program, with completion scheduled for March 9, 2027. That contract has scaled consistently: SCI-reported invoicing reached $22.7 million in FY2022 (122 FTEs, 254,807 contractor hours), $32.6 million in FY2023 (147 FTEs, 306,638 hours), and $38.8 million in FY2024 (183 FTEs, 379,719 hours). Millennium has added two major vehicle wins in 2025: a $249 million BPA from the Office of the Secretary of Defense for AI test and evaluation services in support of the Joint Artificial Intelligence Center, and a $151 billion multiple-award SHIELD IDIQ awarded by the Missile Defense Agency on December 29, 2025, for research, development, prototyping, systems engineering, cybersecurity, and modernization services. A $6.03 million delivery order from the Secret Service under the OASIS+ Unrestricted IDIQ (awarded May 5, 2026) demonstrates current ordering momentum on civilian agency vehicles. Red team training capability is evidenced by a $4.05 million Fleet Cyber Command purchase order for red team training (awarded July 31, 2023, completion January 16, 2028), as well as smaller Naval Sea Systems Command purchase orders for Red Team Apprentice and Journeyman courses ($71.8 thousand in 2023, $59.2 thousand in 2021, $35.4 thousand in 2022).
Customer concentration is heavily weighted toward the Department of the Navy and Department of the Army. The top five funding agencies account for 98% of combined potential value, anchored by Naval Sea Systems Command (11 awards, $82.55 billion combined potential value) driven by the large Seaport-NXG delivery order, followed by Army Materiel Command Aberdeen Proving Ground (4 awards, $37.4 billion), Army Enterprise Information Systems (5 awards, $12.11 billion), GSA Federal Acquisition Service (5 awards, $5.04 billion), and Army Joint PEO Chemical and Biological Defense (12 awards, $2.23 billion). The Navy and Army together dominate the portfolio, though the recent SHIELD and OASIS+ Unrestricted vehicles open pathways to broader defense and civilian agency ordering.
Millennium sits on five major Army IDIQs driving task-order volume: W91ZLK13D0022 (18 task orders, $4.6 million combined potential value), W15QKN10D0009 (17 task orders, $3.2 million), W15QKN13D0010 (14 task orders, $2.3 million), W15QKN08D0002 (13 task orders, $3.4 million), and W15QKN13D0036 (11 task orders, $17.7 million). These vehicles support rapid-ordering for engineering, program management, and operational support across Army installation and acquisition commands. The Seaport-NXG contract represents Navy's primary professional services vehicle; SHIELD and OASIS+ Unrestricted provide forward-looking multi-agency reach.
Activity has remained relatively flat year over year — five awards in 2022, five in 2023, six in 2024, and six in 2025 — suggesting steady-state ordering rather than rapid growth. Only two awards (combined potential value $212.8 million) face ultimate completion inside the next twenty-four months, presenting limited near-term recompete risk in the formal sense, though the Seaport-NXG order does reach completion on March 9, 2027. On the SCI-reportable prime service-contract footprint alone, Millennium invoiced $113.1 million across three fiscal years (FY2022–FY2024), with a rising trajectory: $31.8 million in FY2022, $37.7 million in FY2023, and $43.7 million in FY2024. The vendor's SCI-reported federal services workforce scaled from 162 FTEs in FY2022 to 168 in FY2023 to 201 in FY2024. Government-paid hourly rates on prime service contracts averaged around $106/hr (median), spanning a range from $85.72/hr (10th percentile) to $123.51/hr (90th percentile), typical of systems engineering and program management labor on defense contracts.
Millennium operates as a prime builder of its own delivery teams on the flagship Navy contract but engages subcontractors for specialized work. Across SCI-reportable prime contracts, subcontractors performed roughly 18% of contractor hours, with 38 named subcontractors reported. The Seaport-NXG order specifically names Zygos Consulting LLC, Globalkynect Solutions LLC (8(a) and SDVOSB-certified), and MLT Systems LLC (SDVOSB-certified) as subs, alongside a multi-vendor technical services team including Odyssey Systems Consulting Group, G2 Software Systems, 3P Solutions Inc., Tristar Inc., Huntington Ingalls Industries, Securepro Inc., and Endevelopment LLC. In its subcontractor role, Millennium delivers red team training, cybersecurity services, and operational support to DCS Corporation on Army PEO Ground Combat Systems work (multiple sub awards across 2023–2024), to Valiant Global Defense Services on DoD Cyber Red Team initiatives, to ECS Federal on FBI cybersecurity support under ITSSS-2 REBL, and to Maveris LLC on information security risk management assessments. The sub-award activity (13 recent sub awards across multiple defense primes) indicates Millennium functions simultaneously as a prime on large Navy and Army vehicles and as a trusted specialized-services subcontractor to larger integrators.
