GK Mechanical Systems LLC

GK Mechanical Systems LLC, a Connecticut-based manufacturer of precision mechanical components and assemblies for defense and naval shipbuilding applications, operates as a prime contractor (99% of awards) supplying the Defense Logistics Agency and Department of Navy programs through full-and-open competitive procurement with no set-aside posture. The company is a subsidiary of Novaria Holdings LLC (doing business as Novaria Group), based in Fort Worth, Texas, and has been registered in SAM.gov since 2002.

GK Mechanical Systems delivers specialized hardware—quick receiver assemblies, K-lock adapters, locking sleeves, pole assemblies, guard rail sections, strut assemblies, mounting plates, and related structural fittings—predominantly to three Defense Logistics Agency divisions: Troop Support Construction and Equipment (262 awards, $5.2 million combined potential value), Land and Maritime (125 awards, $4.9 million), and Aviation (140 awards, $2.3 million). These three divisions account for 90% of the company's award volume. By dollar magnitude, the top-five customer ranking shifts slightly: the Army Materiel Command Aviation and Missile Life Cycle Management Command anchors the highest value ($6.3 million across 7 awards), followed by DLA Troop Support Construction and Equipment and DLA Land and Maritime, with Naval Air Systems Command Naval Air Warfare Center and Naval Supply Systems Command rounding out the top tier. The company's 720 awards in the source data span 2003 to present, with peak activity in 2023 (42 awards) and 2022 (40 awards), declining to 4 awards in 2026 year-to-date. Activity was predominantly full-and-open, though several awards carried Total Small Business set-aside designations (access hole frames, strut awnings, guard rail sections, twist-lock assemblies, safety rails, and tie-down hardware). The recompete cliff is minimal—only one award completing in the next twenty-four months.

GK Mechanical Systems places the bulk of its work through five indefinite delivery contracts: SPE7LX19D0145 (14 task orders, $453 thousand), SPE4A714D5097 (11 task orders, $106 thousand), SPE4A717D5278 (9 task orders, $46 thousand), SPE4A719D5107 (5 task orders, $162 thousand), and W58RGZ11D0306 (3 task orders, $1.4 million). Representative prime work includes a $592,128 Naval Supply Systems Command purchase order for 48 SEPA strut assemblies (August 2023), a $481,104 NAVSUP order for strut assembly (August 2023), a $190,668 DLA Land and Maritime purchase order for safety rails under a Total Small Business set-aside (September 2021), and a $156,112 DLA Land and Maritime award for 22 strut awning units (June 2024). The company also holds a five-year, $854,549 indefinite delivery plumbing contract with DLA Land and Maritime for drain cocks, drain cleaning, maintenance, and installation services, against which the agency has issued ten delivery orders totaling $454,849 for work performed in Brookfield, Connecticut.

In its subcontractor role, GK Mechanical Systems supplies long-lead materials and components to major naval shipbuilders: Electric Boat Corporation (streamlined changes couplings for SSBN 826 submarine construction, multiple orders 2023–2025), Huntington Ingalls Inc. (engineering efforts and steel locks for CVN 80 carrier construction, February 2025), and AAR Government Services (blade fold kits for HH-60 helicopters, May 2025). The company also subcontracts to Defense Systems and Solutions on UH-60M aircraft modification and delivery work in Jordan-unique configuration (May 2026).

The company's capability footprint clusters in aircraft parts and auxiliary equipment manufacturing (352 awards), hardware manufacturing (117 awards), overhead traveling crane, hoist, and monorail system manufacturing (33 awards), and bolt, nut, screw, rivet, and washer manufacturing (29 awards). Top procurement service codes span aircraft ground servicing equipment (239 awards), airframe structural components (103 awards), hardware commercial (95 awards), marine hardware and hull items (61 awards), and safety and rescue equipment (49 awards). Combined potential value across all awards is $28.1 million, with $26 million obligated (93% execution rate). Recent awards are nearly all firm fixed-price purchase orders under $200,000 ceiling; larger contracts (those approaching or exceeding $400,000) tend to be strut assemblies and receiver-class components for naval shipbuilding support.
