Gramberg Machine Inc.

Gramberg Machine Inc., a for-profit manufacturing firm based in Oxnard, California, fabricates specialized electronic warfare components and production hardware for naval defense systems as a prime contractor (81% of awards) and subcontractor, operating predominantly under small business set-aside vehicles. The vendor's capability portfolio centers on precision machining, fabrication, and assembly of enclosure covers, tactical clamps, frame sleeves, panel assemblies, and maintenance carts for electronic warfare and electronic attack communication jamming systems serving airborne and ground-based platforms.

The Naval Air Warfare Center dominates Gramberg's customer base, accounting for 94% of awards (12 awards) with a combined potential value of $20.3 million. The Department of the Navy Naval Air Systems Command places the remaining Navy activity. A single delivery order from the Air Force Materiel Command's Warner Robins Air Logistics Complex worth $8 thousand rounds out the customer set. Gramberg's primary vehicle is a five-year, $20 million multiple-award indefinite delivery contract awarded by the Naval Air Warfare Center on September 28, 2023, under total small business set-aside, running through September 27, 2028. This contract procures electronic warfare components and fabrication services; Gramberg has received three delivery orders totaling $267 thousand against it since award, including a $13,660 order in September 2023 for production hardware supporting EW and EA jamming systems, a $72,300 June 2024 delivery order for enclosure covers, tactical clamps, and top panel assemblies for the ALQ-167 system, and a $180,690 delivery order issued March 12, 2026, for similar production hardware with ultimate completion March 31, 2026. A prior single-award procurement from the Naval Air Warfare Center in October 2021 delivered ALQ-167 maintenance cart fabrication for $27,750. Recent activity shows modest but accelerating volume — one award in 2021, two in 2023, one in 2024, three in 2025, and one in 2026 — against a combined potential value of $23.4 million across all sources. In its subcontractor role, Gramberg supplies labor, materials, and travel support for JEACO products under General Dynamics Global Force, LLC on three sub-awards issued between January and March 2025. The vendor's work is concentrated in Southern California, with performance primarily at Oxnard, California and Naval Air Station Point Mugu.
