Mactaggart, Scott & CO. LTD

Mactaggart, Scott & CO. LTD, a British manufacturer of hydraulic motors and marine equipment components, operates as a prime contractor supplying the U.S. Navy and Coast Guard with specialized equipment overhaul, repair, and procurement services. The company does not compete under small business set-asides; 98 percent of its recent award portfolio consists of prime contracts awarded on full-and-open or sole-source bases, reflecting its position as the original equipment manufacturer for several hydraulic motor lines and the only qualified source for certain specialized maritime hydraulic systems.

Headquartered in Loanhead, United Kingdom, Mactaggart, Scott & CO. LTD is a for-profit corporate entity registered in SAM.gov since 2011. The company's capability portfolio centers on the design, manufacture, overhaul, and repair of hydraulic motors and hydraulic components for surface vessels and submarines, with secondary work in bearing assemblies, seals, and miscellaneous marine hardware. Recent representative work includes a $1,725,027 delivery order from the U.S. Coast Guard (September 2025) for the purchase of three inhaul winch motors under the company's $17.7 million Coast Guard IDC; a $1,562,310 delivery order from Naval Sea Systems Command (October 2024) for OK 542 and OK 634 hydraulic motor parts and motor housing assemblies; a $2,308,661 purchase order from NAVSEA (September 2023) for one large hydraulic winch motor to support shipbuilding; and a $1,093,684 delivery order from NAVSEA (December 2025) for two additional motors under the BOA contract.

Customer concentration is heavily weighted toward the maritime services branches. The top two agencies account for 99 percent of awards by count and 100 percent by combined potential value: the Department of Homeland Security U.S. Coast Guard holds 41 awards worth $28.2 million combined potential value, and the Department of the Navy Naval Sea Systems Command holds 36 awards worth $22.7 million. The Department of the Navy Naval Supply Systems Command adds six awards valued at $2.7 million, with Defense Logistics Agency Land and Maritime and Defense Logistics Agency Troop Support rounding out the customer set. The rankings track closely — no tension between volume and dollars — reflecting sustained, steady ordering across two primary customers in maritime maintenance and modernization.

Mactaggart, Scott & CO. LTD holds three significant IDVs anchoring its federal footprint. The Coast Guard Indefinite Delivery Contract HSCG4016D40328, valued at $17.7 million and running through September 2029, covers overhaul and purchase of inhaul winch motors for WLM-175, WLB-225, and WLBB-240 class cutters, with 11 delivery orders placing recurring task work. NAVSEA's Indefinite Delivery Contract 70Z08524DIBCT0012, valued at $4,573,288 and running through August 2029, covers OK 542 and OK 634 hydraulic motor parts and related services, with 11 task orders. NAVSEA's Basic Ordering Agreement N6449822G4002, valued at $4,397,562 and expiring December 2026, covers original equipment manufacturer hydraulic motors with integrated brakes, with three task orders. Place of performance spans Great Britain (primary manufacturing), the United States (Philadelphia, Pennsylvania; Bremerton, Washington; Baltimore, Maryland), and other domestic and overseas locations as required for delivery and integration into naval vessels.

Award activity has grown from seven awards in 2021 to a peak of eighteen in 2024, with five awards year-to-date in 2025 (as of December 9, 2025). The company faces minimal recompete cliff exposure — one award with an ultimate completion date in the next twenty-four months carries a combined potential value of $1.1 million. Combined potential value across all 89 awards (87 prime, 2 sub) stands at $53.7 million, with $23.4 million obligated. The vendor's sub footprint is negligible; two sub awards to Curtiss-Wright Electro-Mechanical Corporation (October 2024) for Rotational Deployment Mechanism repair kits and supplies represent less than 2 percent of activity, with Mactaggart, Scott operating as prime on the vast majority of its federal work.
