Epsilon Systems Solutions Inc.

Epsilon Systems Solutions Inc., Mission Readiness Group Division, a for-profit manufacturer headquartered in Portsmouth, Virginia, provides ship maintenance, repair, engineering, and modernization services for U.S. Navy surface vessels and submarines as a prime contractor holding multiple large-value indefinite delivery vehicles. The division competes predominantly full-and-open across Navy service and supply commands, with 91% of recent awards as prime (1,034 of 1,141 total awards) and no recurrent set-aside designations; a small business set-aside appears on three recent IDIQs but does not characterize the overall prime footprint.

Naval Sea Systems Command (NAVSEA) accounts for dominant customer concentration, 660 awards valued at $15.81 billion combined potential value—covering 88% of awards and 98% of combined dollars across the top customer tier. U.S. Fleet Forces Command (Atlantic) follows with 182 awards ($237.1 million), Naval Air Systems Command with 75 awards ($148 million), Naval Supply Systems Command with 44 awards ($175.3 million), and Naval Facilities Engineering Command with 43 awards ($146.2 million). The portfolio is heavily Navy-centric; the top five customers account for 88% of award count and substantially larger shares of dollar value.

Epsilon's capability footprint centers on littoral combat ship (LCS) sustainment, surface combatant and amphibious ship hull mechanical and electrical (HM&E) repair, landing craft air cushion (LCAC) support, naval valve manufacturing and repair, and submarine engineering. Representative work includes a $1.676 billion multiple-award IDIQ awarded May 23, 2025, for LCS Class Sustainment Execution in San Diego covering preventative maintenance, continuous maintenance, facilities maintenance, and CNO availabilities on LCS vessels homeported on the West Coast; a $669.9 million multiple-award IDIQ awarded September 11, 2024, for maintenance, repair, and modernization of non-nuclear surface ships homeported in Pearl Harbor; a $496.1 million multiple-award IDIQ awarded July 25, 2024, for engineering and technical services under the 41-43 MAC framework; a $1.906 billion multiple-award IDIQ awarded September 2, 2025, for Lot 2 Non-Critical Systems Engineering support related to Chief of Naval Operations availabilities on fast attack submarines; and a $25 million IDIQ awarded September 4, 2025, for unmanned hyperbaric system services from Naval Facilities Engineering Command. Delivery order activity is dense: across the award portfolio, task orders typically range from tens of thousands to several million dollars, with firm fixed-price pricing predominant and completion windows ranging from weeks to nearly two years.

Vehicle position is extensive. Epsilon holds prime positions on the Littoral Combat Ships Class Sustainment Execution Contract - West Coast Part III ($1.676 billion, 74+ task orders), Complex and Non-Complex Maintenance on Surface Combatant and Amphibious Class Ships - San Diego (multiple-award IDIQ, 74+ task orders, $105.7 million combined value), Surface Ships - Emergent Maintenance, Continuous Maintenance and Chief of Naval Operations Availabilities (multiple-award IDIQ), HRMC Emergent Maintenance, Continuous Maintenance, and Chief of Naval Operations Availabilities on Surface Ships ($669.9 million, multiple-award), Hull, Mechanical and Electrical Repair and Maintenance - Mid-Atlantic Regional Maintenance Center (including a $98.03 million total small business set-aside IDIQ awarded May 14, 2025), Engineering and Support Services for Hull, Mechanical and Electrical Systems (multiple-award), Complex and Non-Complex Maintenance on Surface Combatant and Amphibious Class Ships - Norfolk (multiple-award), and CNO Availabilities for Fast Attack Submarines (including a $1.906 billion Lot 2 award). Additionally, Epsilon holds a $98.16 million IDIQ for SUBSAFE and Level 1 TR-317 Series hull penetrator assemblies (awarded March 5, 2026) and a $172 million multiple-award IDIQ for Submarine Corporate Component Repairs Program from Naval Supply Systems Command (awarded August 11, 2025, with option years through August 11, 2027).

Activity has grown year over year across the past five years—109 awards in 2022 to 168 in 2025—though 2026 shows 64 awards to date reflecting the partial-year snapshot. Forty-six awards with ultimate completion dates in the next twenty-four months carry combined potential value of $88.2 million, representing near-term recompete exposure. SCI-reported invoiced revenue on federal service contracts totaled $38.5 million across FY2022–FY2024 (FY2022: $8 million, FY2023: $18.1 million, FY2024: $12.3 million), with workforce delivery of 27.2 FTEs in FY2022, 60.7 in FY2023, and 16.7 in FY2024 on SCI-reportable prime contracts. Government-paid hourly rates on SCI contracts ranged from a 10th percentile of $55.32/hr to a median of $212.11/hr and a 90th percentile of $824.69/hr, reflecting a span from labor-intensive maintenance through specialized engineering support. Across SCI-reportable prime contracts, subcontractor hours averaged 2% of total contractor hours, with 2 named subcontractors reported, indicating Epsilon builds most of its own delivery teams on service contracts.

In subcontract roles, Epsilon performs hull, mechanical, and electrical repairs, engineering and technical services, and component manufacturing for major shipyard primes. Named prime contractors include BAE Systems Maritime Solutions San Diego (USS Green Bay and USS Somerset docking selected restricted availability direct subcontract costs, CNO availability for USS Halsey), National Steel and Shipbuilding Company (USS America FY26 docking selected restricted availability repair sub-contracts, USS Harpers Ferry FY25 selected restricted availability), Metro Machine Corp. (USS Truman FY26 pre-RCOH, USS Oak Hill FY25 docking selected restricted availability), Huntington Ingalls Incorporated (DDG 1000/1001 modernization period planning, FY21 RCOH accomplishment), and Teledyne Brown Engineering (production of FMS boats U1, U2, and U3 engineered systems and services). This subcontract posture—roughly 9% of total awards—reflects a primary-prime model where Epsilon anchors the portfolio to Navy service and supply direct primes while supplementing with high-value shipyard maintenance work as a tier-one sub to major construction and overhaul contractors.
