About the company
Custom Design & Fabrication, LTD, operating as C D F, is a woman-owned small business manufacturer based in Deptford, New Jersey, that designs and fabricates specialized hot water heating equipment (commonly called "monkey heaters") for Navy diving and submarine operations, selling exclusively to the federal government as a prime contractor through firm-fixed-price purchase orders.
The vendor holds a dominant, single-customer concentration with the Department of the Navy. U.S. Fleet Forces Command (Atlantic Fleet) accounts for 18 of 31 awards and $704 thousand in combined potential value across the recent portfolio, while Naval Sea Systems Command accounts for 7 awards and $118 thousand. Together, these two Navy commands represent 81% of recent award count and 99% of combined potential value. The Department of the Interior's U.S. Geological Survey Office of Acquisitions and Grants, Naval Construction Forces, and Navy Installations Command round out the customer set with single or dual awards. Over the past five years, activity has remained flat at one to two awards per year, with the most recent award a January 2026 total small-business purchase order from Naval Sea Systems Command for a PWH100/3 heater operations and maintenance training course valued at $9,950.
Custom Design & Fabrication operates without parent contract vehicles or seat on government-wide acquisition contracts; every award is a standalone purchase order issued on a spot-buy or sole-source basis. The company specializes in three interrelated service lines grounded in its monkey-heater core: equipment manufacturing and parts supply, field training and operator certification, and maintenance support. Representative work includes a $98,900 custom hot water heater delivery to the Department of the Interior (April 2025), a $77,394.95 order from Fleet Forces Command for monkey-heater parts, training, and a cabinet for the Navy Submarine Support Facility in Groton, Connecticut (July 2022), and a $60,830.77 sole-source parts contract from Fleet Forces Command (January 2024). The vendor has consistently held sole-source designation under FAR 6.302-1 across multiple awards, reflecting Navy determination that Custom Design & Fabrication is the only responsible source for specialized diving hot-water equipment. The source data reports 31 total awards with $1 million in combined potential value; 100% of that value has been obligated. Custom Design & Fabrication operates solely as a prime contractor with no subcontract footprint.
