Epsilon Systems Solutions Inc.

Epsilon Systems Solutions Inc., Mission Readiness Group Division, is a for-profit manufacturer headquartered in Portsmouth, Virginia, providing ship maintenance, repair, engineering, and modernization services for U.S. Navy surface vessels and submarines as a prime contractor on large-value indefinite delivery vehicles and delivery orders. The division operates as a child entity under parent Epsilon Systems Solutions, Inc., based in San Diego, California, and competes predominantly on full-and-open federal contracts without set-aside designation, though a subset of awards carry total small business set-asides.

Naval Sea Systems Command dominates the customer base with overwhelming concentration. The top five Navy commands account for 88% of awards by count, led by Naval Sea Systems Command (NAVSEA) with 697 awards valued at $15.86 billion combined potential value—a span encompassing ship maintenance, repair, and modernization across surface combatants, amphibious vessels, and littoral combat ships. The potential-value ranking mirrors the count ranking closely, with NAVSEA anchoring the portfolio, followed by Military Sealift Command ($238.5 million across 18 awards), U.S. Fleet Forces Command Atlantic ($237.5 million across 186 awards), Naval Supply Systems Command ($175.4 million across 46 awards), and Naval Air Systems Command ($148 million across 75 awards). The remaining 30 federal customer agencies combined represent 12% of awards and a small dollar share, signaling a Navy-dominant, NAVSEA-centric footprint.

Epsilon holds positions on multiple large-value parent vehicles spanning surface combatant maintenance, littoral combat ship sustainment, and submarine engineering. The $1,676 billion Littoral Combat Ships Class Sustainment Execution Contract - West Coast Part III (awarded May 23, 2025) is the largest active vehicle, supporting preventative maintenance, continuous maintenance, facilities maintenance, and CNO availabilities on LCS vessels homeported on the West Coast; 44 task orders have been placed under this vehicle. The $1,906 billion Lot 2 Non-Critical Systems Engineering IDIQ for fast attack submarine CNO availabilities (awarded September 2, 2025) anchors submarine engineering work across Portsmouth, Virginia and subordinate naval shipyards. The two $98 million plus Complex and Non-Complex Maintenance IDIQs (San Diego and Norfolk) cover hull, mechanical, and electrical repairs on surface combatants and amphibious vessels. Older vehicles still generating task orders include the Non-Nuclear Ship Repair East and West IDIQs (NAICS 336611), which together account for 618 awards and over $7.5 billion in combined potential value. The $172 million Submarine Corporate Component Repairs Program IDIQ (awarded August 11, 2025) targets Los Angeles-class and Virginia-class submarine valve and actuator component-level repairs. A $25 million Unmanned Hyperbaric System Services IDIQ (awarded September 4, 2025) with Naval Facilities Engineering Command represents work outside the primary naval maintenance domain.

Representative prime awards demonstrate breadth of work scope. A $1,676 billion LCS Class Sustainment vehicle (May 2025) covers planned, continuous, and emergent maintenance across 15+ named LCS vessels, with individual delivery orders ranging from $12,000 to $4.1 million. A $7.93 million delivery order for USS Anchorage (LPD-23) hull, mechanical, and electrical repair (February 2026) represents large-scale amphibious vessel work under total small business set-aside. A $2.42 million delivery order for ship repair at Pearl Harbor (July 2026) under the HRMC Emergent Maintenance IDIQ exemplifies regional hub work. A $663,095 delivery order for associated components for cable cutter and reel machines (July 2026) under a $2.2 billion single-award IDIQ demonstrates component manufacturing work performed in Portsmouth. A $2,022,563 delivery order for Landing Craft Air Cushion and Ship-to-Shore Connector support (September 2025) shows amphibious craft sustainment scope. Naval Supply Systems Command purchase orders for ball valves and actuators—ranging from $12,752 to $243,982 per order—comprise a recurring product revenue stream.

Activity has grown year over year from 2022 through 2025: 109 awards in 2022, 121 in 2023, 150 in 2024, and 171 in 2025. The 2026 total (106 awards through early September) reflects a partial-year snapshot. Thirty awards with combined potential value of $44.8 million reach ultimate completion inside the next twenty-four months, presenting recompete exposure and pipeline risk.

Across SCI-reportable prime service contracts, Epsilon invoiced $66.1 million from FY2022 through FY2025. FY2025 showed strongest invoicing at $27.6 million with 45.3 FTEs; FY2023 invoiced $18.1 million with 64.1 FTEs; FY2024 invoiced $12.3 million with 16.7 FTEs; FY2022 invoiced $8 million with 27.2 FTEs. On federal services contracts captured in SCI, median government-paid rates ran around $212/hr, with senior labor pricing reaching $824.69/hr and junior labor priced around $55.32/hr. Across SCI-reportable prime contracts, subcontractors accounted for roughly 1% of total contractor hours—indicating Epsilon builds its own delivery teams on these service engagements rather than relying on sub labor. The SCI dataset carries only 27 records (26 prime, 1 sub named), representing service contracts above the $150,000 threshold and excluding goods, components, classified work, and non-federal revenue; SCI is a partial view of the division's federal activity, a small fraction of the delivery-order flow visible in the prime award list.

In its subcontractor role, Epsilon performs hull, mechanical, and electrical repairs, component manufacturing, and engineering support for prime contractors including BAE Systems Maritime Solutions (USS Green Bay, USS Somerset, USS Halsey FY25 DSRA work), National Steel and Shipbuilding Company (USS America LHA 6 FY26 repairs), Huntington Ingalls (DDG 1000/1001 modernization planning), Metro Machine Corp (USS Truman FY26 work), and Teledyne Brown Engineering (FMS boats U1-U3 production). Across the sub footprint, Epsilon subcontracts to major naval shipyard primes executing docking selected restricted availabilities (DSRA), refueling and complex overhaul (RCOH), and new construction support.

The division's service footprint spans San Diego, Norfolk, Pearl Harbor, Mayport, Portsmouth, Bahrain, and overseas deployment locations. Work is performed at naval shipyards, maintenance centers, and aboard vessels worldwide. Administrative oversight and component manufacturing (valve refurbishment, hull penetrator assemblies, cable cutter components) anchors to Portsmouth; ship repair execution centers on San Diego (LCS and surface combatant maintenance), Norfolk (surface combatant and amphibious repair), and Pearl Harbor (regional hub for non-nuclear surface ship maintenance). The geographic distribution reflects Navy regional maintenance center alignment and homeport concentration for the LCS Class.

Epsilon operates as a child entity of Epsilon Systems Solutions, Inc., headquartered in San Diego. The corporate structure positions the Mission Readiness Group Division as the Navy-focused operating unit for the parent company, with primary alignment to NAICS 336611 (Ship Building and Repairing) across the award portfolio. The 1,186 total awards (91% prime, 9% sub) accumulated since 2001 reflect sustained Navy customer relationships, with density growing across the recent five-year period. The combination of large-value IDIQs, steady delivery-order issuance, and component manufacturing capacity positions Epsilon as a dominant Navy ship maintenance and repair provider, with particular strength in littoral combat ship sustainment, surface combatant hull mechanical and electrical repair, and submarine engineering support.
