Turnbull LLC

Turnbull LLC, a Baltimore-based limited liability company and for-profit manufacturer, is the child subsidiary of Trident Maritime Systems, Inc., operating as a prime contractor supplying specialized maritime furniture, seating, equipment, and components to Department of Defense agencies — predominantly the Naval Supply Systems Command, Naval Sea Systems Command, Defense Logistics Agency Land and Maritime, and Military Sealift Command — without competing under small business set-asides. The company competes in full-and-open procurements, primarily NAICS 336612 (Ship Building and Repairing) and NAICS 337214 (Metal Household Furniture Manufacturing), with a federal PSC footprint concentrated in Miscellaneous Ship and Marine Equipment (274 awards) and Household and Miscellaneous Furniture (104 awards combined).

Turnbull's capability portfolio centers on design, engineering, manufacturing, and delivery of custom and standardized shipboard furnishings for naval vessels and shore facilities. Representative prime work includes a $428,946.95 firm fixed-price delivery order from Military Sealift Command for nurses' stations aboard USNS Comfort (T-AH 20), a $232,603 purchase order from Naval Supply Systems Command for 25 operator chairs (NSN 1H-2090-011779884-X5) with delivery to DLA distribution locations, a $193,563 delivery order to DLA Land and Maritime for pedestal ship chairs, and singular high-value awards from Military Sealift Command for stateroom furniture and laboratory upgrades aboard hospital ships USNS Earl Warren and USNS Mercy. Recent smaller purchase orders span operator chairs, watch supervisor chairs, sonarman's chairs, revolving stools, folding bulkhead seats, special-purpose chairs, and hardware components including clamps, bearings, and fasteners. Performance is centered at Turnbull's Baltimore facility with delivery directed to DLA distribution centers or directly to naval vessels and shore installations.

Customer concentration is heavily skewed to Navy logistics and supply. The five top-funded agencies account for 81% of recent awards: Defense Logistics Agency Land and Maritime (169 awards, $4.7 million combined potential value), Naval Supply Systems Command (91 awards, $5.3 million), Naval Sea Systems Command (152 awards, $494 thousand), US Pacific Fleet Forces (37 awards, $289 thousand), and Department of the Navy (28 awards, $16 thousand). A secondary concentration emerges in the top-potential-value ranking: Department of the Army Corps of Engineers Engineering Support Center Huntsville (20 awards, $6.9 million combined potential value) anchors the dollars despite lower award count, signaling occasional high-value shipboard or infrastructure modernization work. Most procurements route through Naval Supply Systems Command and DLA as purchase orders and delivery orders rather than standing contract vehicles.

Turnbull holds a seat on the Federal Supply Schedule GS27F0431G (84 task orders, $9.8 million combined potential value) and places work through two single-award indefinite delivery contracts with DLA Land and Maritime each valued at $250,000 for pedestal ship chairs. The vendor also has engagement on indefinite delivery contract SPE7M320D61RK (10 task orders, $250 thousand) and sporadic task orders under PMW 750 C4I Testing Integration and Installation 2019.

Activity has been volatile. Five-year trajectory shows 24 awards in 2022, 20 in 2023, a spike to 106 in 2024, then 23 in 2025 and one award in 2026 year-to-date. Only one award (combined potential value $33 thousand) faces ultimate completion within the next twenty-four months, limiting near-term recompete pressure. Combined potential value across all 588 awards stands at $23.1 million, though combined dollars obligated reach $86.4 million (374% of potential value), indicating that actual invoiced delivery has substantially exceeded the original contract ceiling estimates over Turnbull's contract lifetime.

In its subcontractor role, Turnbull supplies modular bathroom units, berths, cabinets, desks, chairs, lockers, and related furnishings to Huntington Ingalls Inc. on CVN 80/81 aircraft carrier detailed design and construction efforts, CVN 74 refueling and complex overhaul work, and related modernization programs. Turnbull also subcontracts to Electric Boat Corporation on submarine construction and to Scientific Research Corporation on CVN 74 completion labor. The sub-award footprint is heavily skewed to ship construction and overhaul for Huntington Ingalls (the parent of its own shipbuilding operations), reflecting Turnbull's established position as an Original Equipment Manufacturer (OEM) of technical data and custom maritime furnishings with sole-source sourcing in multiple Navy procurements.
