California Marine Supply Inc.

California Marine Supply Inc., a for-profit manufacturer based in Flagstaff, Arizona, supplies electric sirens, signal horns, and maritime electrical signaling equipment to the Department of Defense as a prime contractor (92% of recent awards) and subcontractor on naval ship repair and maintenance programs. The vendor competes full-and-open with no set-aside designations across its entire federal footprint, operating as a Qualified Products List supplier specializing in military-specification electrical components for defense logistics and naval operations.

The company's customer concentration is tightly aligned with Defense Logistics Agency operations. DLA accounts for 96 awards and $7.2 million in combined potential value across three divisions: Troop Support Construction and Equipment (26 awards, $3 million), Land and Maritime (48 awards, $2.1 million), and Aviation (22 awards, $2.1 million). The Department of the Navy Naval Supply Systems Command and Naval Sea Systems Command together account for 30 awards and $1.055 million, capturing 99% of the vendor's combined potential value. This customer concentration reflects a narrow, recurring procurement demand for electric motorcycle sirens (National Stock Number 6350016478473 or variants) and signal horns across naval fleet maintenance and troop support logistics channels. California Marine Supply holds a single-award Indefinite Delivery Contract with DLA Land and Maritime awarded March 27, 2025, with a $250 thousand ceiling, a guaranteed minimum of 2 units, and an estimated 12 orders per year through March 27, 2026. One delivery order for $22,220 was issued under this contract as of December 11, 2025. The vendor also places orders under several older DLA and Navy IDIQs carrying minimal recent activity.

Activity has remained flat at seven to eleven awards per year over the past five years, with no apparent growth trajectory. All 141 awards in the source data are fully obligated; the combined potential value of $8.3 million equals actual dollars obligated across the portfolio. Representative prime work includes a $276,055 purchase order from DLA Troop Support Construction and Equipment (November 25, 2025) for 65 electric motor sirens (NSN 6350016478473) with delivery by May 4, 2026; a $212,160 purchase order from the same division (April 10, 2024) for 60 electric sirens with 137-day delivery; and a $200,367 purchase order from Naval Supply Systems Command (January 26, 2023) for signal horns with delivery by August 31, 2023. Awards cluster tightly around two National Stock Numbers and represent repeated procurement of the same qualified product at similar unit volumes, indicating stable but non-growing demand.

In its subcontractor role, California Marine Supply supplies electrical components and materials to BAE Systems Maritime Solutions on ship repair modifications across multiple destroyer and amphibious warfare platforms (Jack H. Lucas DDG 125, USS Essex, USS Kearsarge), to QED Systems on 400-hertz distribution modernization and shipboard systems installation tasks aboard LHA6 and LPD 17-class vessels, and to Vigor Marine on surface combatant maintenance work. The vendor's NAICS and PSC profile centers on Other Communications Equipment Manufacturing (70 awards, primarily signal and alarm equipment) and Ship Building and Repairing (13 awards), with secondary exposure to transformer and electrical control components. The company maintains a SAM registration dating to 2002 and brings over 35 years of experience supplying electrical equipment to naval and defense logistics customers.
