About the company
Mellinger Engineering, Incorporated, a veteran-owned precision valve component manufacturer headquartered in Sonoma, California, operates as a prime contractor (63% of recent awards) and subcontractor on naval defense programs, competing predominantly under Total Small Business set-asides. The company manufactures high-precision valve components — including ball valves, check valves, lift-check valves, stop-check valves, in-line stop valves, and gate valves — engineered to military specifications (MIL-I-45208 and MIL-I-45208A inspection protocols) and delivered primarily to Portsmouth Naval Shipyard and Naval Sea Systems Command facilities. Mellinger registers under NAICS 332919 (Other Metal Valve and Pipe Fitting Manufacturing) and PSC 4820 (Valves, Nonpowered).
Customer concentration is absolute: all 24 prime awards and all customer agency exposure flow through the Department of the Navy, with Naval Supply Systems Command (NAVSUP) accounting for the entire $14 million combined potential value across the prime footprint. Representative recent prime work includes a $1.858 million December 2025 definitive contract from NAVSUP for 346 globe valve units (NSN 3H-4820-015766630-L1) delivered to Portsmouth Naval Shipyard by August 2027; a $1.273 million August 2024 check valve contract (NSN 1H-4820-014396062-L1) for delivery by February 2027; and a $1.481 million July 2025 ball valve contract (17 units, NSN 7H-4810-014851330) due December 2026. The company has secured approximately $10.8 million across twenty-two NAVSUP prime awards since 2021. All prime awards carry Total Small Business set-aside designation; one March 2022 contract (check valves, $429,840) carried no set-aside designation.
The subcontractor footprint anchors to nuclear submarine construction and overhaul. Mellinger supplies valve components to Huntington Ingalls Inc. on CVN-class carrier engineering efforts and refueling/complex overhaul (RCOH) work, with three sub-awards in June 2025 covering in-line stop valves (CVN 80 engineering) and gate valves for CVN 75 RCOH advance planning. The company also subcontracts to Electric Boat Corporation on SSBN 826 streamlined changes, SSBN 814 long lead time material, and SSN 804 construction (FY20, Boat 1), with nine sub-awards spanning 2022–2024. Subcontract work involves specialized valve engineering and supply supporting new construction and overhaul cycles on attack and ballistic-missile submarine programs.
Activity has grown significantly: seven awards in 2022, declining to five in 2023, then accelerating to twelve in 2024 and nine in 2025. Seven awards (combined potential value $6.3 million) face ultimate completion inside the next twenty-four months, creating recompete exposure. The source reports $19 million in combined dollars obligated across the footprint, indicating prior-year funding concentration ahead of recent award dates. All work is performed at the Sonoma, California facility and requires strict compliance with Buy American Act, Balance of Payments Program, and Defense Priorities and Allocations System (DPAS) rating requirements, with first article testing and material traceability certification mandated on all military valve procurements.
