Atlantic Fabrication & Boiler Services, Inc.

Atlantic Fabrication & Boiler Services, Inc., a Portsmouth, Virginia–based small business manufacturer, operates predominantly as a prime contractor (95% of recent awards) delivering ship repair, maintenance, and fabrication services to the Department of Defense, the Department of Homeland Security, and civilian maritime agencies. The company is a for-profit Subchapter S corporation holding total small business set-asides on eight significant IDIQs and competing on full-and-open contracts across multiple federal maritime agencies. Atlantic Fabrication has registered in SAM.gov since 2003 and has built a portfolio of 350 total awards spanning over two decades, with recent activity accelerating substantially — from six awards in 2022 to 28 in 2025 and 23 through August 2026.

The vendor's concrete capability footprint centers on depot-level and voyage repair services for naval vessels: boiler fabrication, piping repairs, welding, insulation installation, tank cleaning and inspection, structural repairs, and equipment replacement. Representative prime work includes a $4.22 million Military Sealift Command delivery order for USNS Comfort fall voyage repair availability (September 2025, East Coast General Ship Repair IDIQ), a $1.34 million MSC delivery order for USNS Comfort voyage repair (May 2025, same vehicle), a $1.002 million MSC delivery order for USNS Medgar Evers voyage repair availability (March 2026, East Coast General Ship Repair IDIQ), a $810,676 MSC emergency voyage repair order for USNS Oscar V. Peterson (January 2026), and $501,529 for USNS Kanawha May voyage repair (April 2026). Coast Guard work includes a $417,835 definitive contract for USCGC Seneca FY26 availability (February 2026) and multiple smaller purchase orders ($37,056 for controllable pitch propeller flush, $214,842 for sewage repair on USCGC Diligence, $103,219 for tank cleaning and inspection). The vendor also performs Army watercraft maintenance through recent Army awards.

Customer concentration sits overwhelmingly with the Department of the Navy's Military Sealift Command, which accounts for 278 of 342 awards (81% of prime and sub combined) and $419.1 million of $1.15 billion combined potential value across all awards. The second-largest customer, TACOM Life Cycle Management Command, drives the dollar concentration via three recently awarded large IDIQs (January 2026): a $241.4 million Army Watercraft Sustainment Maintenance Program Zone 1 (CONUS) contract, a $211 million Zone 2 (OCONUS) contract, and a $69.8 million Zone 3 (pier-side) contract. Naval Sea Systems Command ranks third in dollars ($129.5 million across 21 awards) through two total small business set-aside maritime boatyard support IDIQs awarded in FY2025: a $59.66 million Lot I contract (September 2025) and a $52.9 million Lot II contract (December 2025), plus a $17 million lightweight modular berths IDIQ (August 2025). The Coast Guard (23 awards, $4.3 million) and NOAA ($73.9 million across five awards) round out the active set. The split between by-award-count and by-potential-value rankings reveals that MSC places many task orders on standing IDIQs (high volume, moderate individual size), while TACOM's recent awards are fewer but massive in ceiling value.

Atlantic Fabrication holds seats on seven named parent IDIQs with live task-order activity: the $140 million East Coast General Ship Repair IDIQ with MSC (16 task orders, $9.5 million combined potential value through September 2028), the $2.78 million Coast Guard insulation repairs IDIQ for 210-foot and 270-foot cutters (through January 2029), the $73.8 million NOAA Fleetwide Dockside and Ship Maintenance IDIQ (through August 2028), the three recently awarded TACOM Army Watercraft Sustainment Maintenance Program contracts (Zone 1, Zone 2, Zone 3; through July 2031), the Naval Sea Systems Command Lot I and Lot II Marine Boatyard Support IDIQs (through September 2026 and December 2026 respectively), and the Naval Sea Systems Command lightweight modular berths IDIQ ($17 million, through August 2030). Additionally, Atlantic Fabrication holds positions on several legacy MSC ship-repair vehicles (N4044209D7200 with 59 task orders at $9.5 million combined potential value; N3220518D4914 with 29 task orders at $8.5 million).

Activity has grown significantly year over year — from six awards in 2022 to 28 in 2025 — with only four awards completing in the next twenty-four months carrying combined potential value of $167 thousand, indicating minimal near-term recompete exposure. The vendor operates almost entirely as a prime contractor (95% of awards); across the single SCI-reportable record (FY2024), Atlantic Fabrication delivered as a named subcontractor under a prime contract, representing 3.2 FTEs on that sub engagement. In recent federal contract sub-award work, Atlantic Fabrication subcontracts to East Coast Repair & Fabrication LLC on Navy surface combatant and amphibious class vessel work (USS Gettysburg, USS San Antonio, USS IWO Jima, USS Oak Hill platform repairs and modifications), to Metro Machine Corp. on docking and extended restricted availability work (USS Oak Hill, USS Porter), and to Marine Hydraulics International and Epsilon Systems Solutions on specialized vessel system installations. The vendor's own sub footprint is lean relative to its prime posture; it functions primarily as a direct deliverer of fabrication and repair labor rather than as a teaming lead that subs out portions of scope.

Federal contract NAICS concentration aligns tightly with the maritime repair mission: ship building and repairing (278 awards) dominates, with minor presence in commercial and industrial machinery repair (14 awards), fabricated structural metal manufacturing (13 awards), and pipe and tube manufacturing (6 awards). PSC coding similarly reflects non-nuclear ship repair (East and West, 247 combined awards) and general maintenance/repair of ship and marine equipment (51 awards). The vendor's set-aside posture is predominantly total small business across its active IDIQs — a characteristic that anchors most new prime awards to set-aside vehicles while allowing competition on full-and-open purchase orders. Combined obligated dollars across all awards stand at $72.5 million (6% of the $1.15 billion potential value ceiling), reflecting the structure of large IDIQs with task orders in early or mid-execution.
