Roman Transportation Inc.

Roman Transportation Inc., doing business as Neptune Marine, is a minority-owned, woman-owned, Hispanic American-owned, DOT-certified disadvantaged business enterprise (DBE) based in Wilmington, California, that supplies spare parts and components for naval shipbuilding and maintenance programs as a subcontractor to prime shipbuilders and as a prime contractor on small Navy and Defense Logistics Agency orders. The vendor operates predominantly as a prime (86% of recent awards) but carries a visible subcontract footprint supplying components to National Steel And Shipbuilding Company on T-AO class (fleet replenishment) oiler construction and maintenance tasks.

Roman Transportation's customer footprint is entirely Navy-centric. The Department of the Navy Naval Sea Systems Command drives 14 of 21 awards and $48 thousand of the combined $57 thousand potential value, with the Naval Supply Systems Command holding 2 awards ($9 thousand), the Pacific Fleet Forces 3 awards, and a single award each to the broader Navy and to the Defense Logistics Agency. Award concentration is tighter on value than on count — NAVSEA's $48 thousand represents 84% of combined potential value — but the vendor's prime posture means it also holds multiple small orders across other Navy commands that carry minimal stated potential value.

Work spans ship components and industrial supplies: top NAICS categories include Ship Building and Repairing (3 awards), Other Electronic Component Manufacturing (2), and Automatic Environmental Control Manufacturing (2); top PSC codes cover Hardware, Commercial (2 awards), Connectors, Electrical (2), Microcircuits, Electronic (2), and Pressure, Temperature, and Humidity Measuring and Controlling Instruments (2). Recent sub work under NAVSEA includes detail design and construction spare parts for the T-AO 205 (Nov 2025), engineering change proposal spare parts for the T-AO 209AF (May 2024), and post-shakedown availabilty spare parts for the T-AO 206 (Mar 2024), all flowing through National Steel And Shipbuilding. Activity has been episodic — two awards in 2024, one in 2025 — following a long gap after 2011, with combined dollars obligated ($299 thousand) exceeding stated potential value ($57 thousand) by a wide margin, signaling that actual invoiced work has outpaced contract ceilings.
