This is a federal contracting justification form (SSGR 4330.51D/3, Attachment 3) for a single-source acquisition under the simplified acquisition threshold of $250,000.

The contracting officer is procuring replacement parts for Submarine Sail Safety Stanchions (Flying Bridge) from GK Mechanical Systems, located in Brookfield, Connecticut. The parts are used during submarine surface operations with a required delivery date of August 14, 2026. The justification for single-source procurement is based on the "Sole Source" rationale: GK Mechanical Systems is the Original Equipment Manufacturer and the only source capable of providing these parts. The parts are shown on the vendor's proprietary drawings and are not available through Navy Stock systems or any other source. No authorized resellers or distributors are identified. The contracting officer, Paul A. Rich, certified this justification on December 4, 2025, with one-level-above approval authority. The document notes that when this requirement is included in a contract action with brand-name specifications or sole-source designation, the contracting officer must include this justification with FAR 13.106-1(b) documentation as required, and for Federal Supply Schedule orders, the RFQ must be posted on e-Buy per FAR 8.405-6.
