Epsilon Systems Solutions, Inc.

Epsilon Systems Solutions, Inc., a 100% employee-owned technical services provider headquartered in San Diego, California, competes as a prime contractor delivering ship maintenance, repair, and modernization services to the U.S. Navy and Military Sealift Command, with recent activity concentrated in small business set-aside and full-and-open competitions across Naval Sea Systems Command delivery orders and multiple indefinite-delivery vehicles.

Epsilon's footprint is dominated by naval ship repair and maintenance work. The company's top customer by both award count and dollar value is the Department of the Navy Naval Sea Systems Command, which accounts for 1,457 awards (66% of total awards) and $13.41 billion in combined potential value (66% of the $20.27 billion total). The second-largest customer by potential value is the Department of Energy National Nuclear Security Administration with $324 million across 15 awards, followed by the Military Sealift Command with $188.9 million across 83 awards. Epsilon also serves the Naval Air Systems Command Naval Air Warfare Center (176 awards, $109.7 million), the U.S. Pacific Fleet Forces (73 awards, $15.9 million), and GSA Federal Acquisition Service (25 awards, $130.5 million), with 51 distinct federal agencies in the award portfolio. The Navy concentration is structural: 86% of awards flow to Navy entities, with the bulk routed through NAVSEA.

Epsilon competes across multiple high-value parent vehicles. The top vehicles by task-order volume include Indefinite Delivery Contract N0024405D0044 (303 task orders, $19.5 million), IDC N0024405D0045 (290 task orders, $56.8 million), and IDC N5523617D0017 (264 task orders, $98.1 million) — all NAVSEA marine boatyard and ship repair IDIQs. The company also holds a $49 million single-award IDC with the Military Sealift Command for West Coast general ship repair awarded January 15, 2025, and a $300 million multiple-award IDC with NAVSEA for complex and non-complex maintenance on surface combatant and amphibious class ships. Recent awards added a $164.3 million definitive contract with NAVSEA for maintenance, repair, and assessment services at the Southwest Regional Maintenance Center (awarded September 30, 2025, running through September 29, 2030 at cost-plus-fixed-fee pricing), a $26 million definitive contract with U.S. Fleet Forces Command for Expeditionary Equipment Readiness Support Services (awarded August 16, 2023), and Epsilon's entry onto the OASIS+ Unrestricted multiple-award GWAC (awarded December 17, 2024, no ceiling specified). Representative recent delivery orders include a $5.14 million total small business set-aside for Littoral Combat Ship planned maintenance availabilities and facility maintenance (August 4, 2025), a $3.66 million order for ACB-1 S2 services under the Marine Boatyard Services IDIQ (February 20, 2023), and a $2.02 million voyage repair order for USNS Washington Chambers under the Military Sealift Command's West Coast General Ship Repair MAC (August 22, 2022).

Capability framing derives from NAICS and PSC concentration: 924 awards span Ship Building and Repairing (NAICS 336611), 915 span Engineering Services (NAICS 541330), and dominant PSC codes are Non-Nuclear Ship Repair (West, 702 awards), Support Professional Engineering/Technical (643 awards), and Maintenance/Repair of Ships and Floating Docks (109 awards). Work encompasses small boat maintenance, deck-level repairs, mechanical systems overhaul, facilities maintenance for surface combatants and amphibious vessels, propulsion system support, and continuous/corrective maintenance availabilities. Specific examples: USS Fort Lauderdale (LPD-28) maintenance availabilities on an amphibious transport dock ($698,233, July 15, 2025, total small business set-aside, 303-hour term), multiple Littoral Combat Ship planned maintenance availabilities ($24.9 million, September 5, 2022), and Mission Compatibility Analysis Tool support for Air Force Systems Engineering and Integration ($581,000, September 30, 2025, no set-aside, under GSA MAS).

Set-aside posture shows mixed deployment: 96% of recent prime awards are total small business set-asides or full-and-open competitive, with roughly 40% of delivery orders carrying total small business set-aside designation and the remainder competed without restriction. Epsilon does not hold SBA 8(a), HUBZone, SDVOSB, or WOSB designations; its small business status derives from employee ownership and size standard classification under NAICS 336611 (500 employees for ship building and repairing).

Service Contract Inventory data (covering federal service contracts above the $150,000 threshold, FY2022–FY2024) shows SCI-reportable invoiced revenue of $123.8 million across three fiscal years: $25.6 million in FY2022 (225 FTEs), $54.3 million in FY2023 (339 FTEs), and $43.9 million in FY2024 (324 FTEs). On federal services contracts captured in SCI, median government-paid hourly rates ran around $63.30/hr, with the 10th percentile at $43.31/hr and the 90th percentile at $125.67/hr. Across prime contracts, subcontractors averaged 15% of total contractor hours, with 54 named subcontractors reported. SCI is a partial view: it excludes goods, products, classified work, and non-federal revenue. The $123.8 million SCI total does not represent Epsilon's total federal revenue or enterprise revenue — the larger award portfolio totals $20.27 billion in combined potential value, but much of that reflects indefinite-delivery-contract ceilings and future task-order potential rather than invoiced dollars.

Epsilon operates as a prime contractor in 96% of awards (2,139 of 2,217 total). On the subcontractor side, the company subcontracts to major primes including Huntington Ingalls Incorporated (for DDG 51 class destroyer construction and other naval shipbuilding work), HII Fleet Support Group LLC (for Surface Engineering Maintenance Assist Team labor and Carrier Engineering Maintenance Assist Team support), BAE Systems Maritime Solutions San Diego, Vigor Marine LLC, and QED Systems, Inc. for pump and motor overhaul services. Named subcontractors on Epsilon's own delivery orders include Naval Engineering Support Inc. (maritime engineering and maintenance), Duke Marine Engineering Consulting Inc. (licensed engineering for LCS maintenance), Rolls-Royce Solutions America Inc. (marine propulsion and OEM support), and Hawaii Marine Cleaning LLC and other maritime service specialists for specialized vessel-support tasks. The sub engagement model shows Epsilon as a prime-focused operator leveraging specialized subs for targeted technical disciplines rather than building broad internal delivery teams.

Activity has declined year over year: 82 awards in 2022 fell to 52 in 2023, rebounded slightly to 64 in 2024, and dropped to 61 in 2025. Only 3 awards appear in the source for 2026 (data captured through April 3, 2026). Over the next twenty-four months, 3 awards with combined potential value of $80.6 million face ultimate completion dates and recompete exposure. The forward pipeline reflects the cyclical nature of ship maintenance: large definitive contracts like the $164.3 million SWRMC award (running through September 2030) anchor near-term execution, while delivery-order volume against marine boatyard and ship repair IDIQs provides steady task-order flow.

The corporate structure includes a named subsidiary, Epsilon C5I Inc., which the source identifies as holding significant contracts including a $4.8 billion NOVASTAR multiple-award IDIQ with the National Air and Space Intelligence Center and positions on OASIS+ and Seaport-NXG vehicles. GSA Schedule labor rates span 96 unique categories, ranging from $50.06/hr (Document Management Specialist) through $307.34/hr (Executive Consultant), with no security-clearance requirements across the portfolio. The schedule posture supports both ship-focused field labor and engineering/analyst roles. Epsilon's federal contracting footprint centers on naval ship sustainment and field engineering support, with concentration in a single customer (NAVSEA) and a disciplined set of parent vehicles that dominate task-order competition.
