TDI power supplies

The Department of the Army Materiel Command Contracting Command at Redstone Arsenal is procuring five TDI power supply units (Part Number 28-2753609-3, NSN 6130-01-487-0203) that are obsolete and end-of-life components critical for maintaining communication systems between firing units. This sole source procurement targets General Dynamics Mission Systems, Inc., as they are the only entity capable of providing these specific 36-year-old power supplies that are no longer manufactured. The procurement includes 1.6 hours per unit of engineering technician labor for evaluation and testing to ensure proper operation through comprehensive testing including full-load operation, battery cycling, and LED verification. Award evaluation will be based on best value to the government, considering factors such as lowest price, lead time, and adherence to part number specifications. Quotations must be submitted via email by 1:00 PM Eastern Time on June 27, 2025, with prospective vendors encouraged to include their business size status.

This solicitation carries no set-aside designation and is unrestricted, falling under NAICS code 335999 with a small business size standard of 600 employees. General Dynamics is identified as the sole source contractor due to their unique capability to provide these obsolete power supplies, having previously supported repairs under earlier contracts before discontinuing support due to obsolescence. The procurement involves exactly five power supply units to be delivered to Letterkenny Army Depot in Chambersburg, Pennsylvania, where they will support depot manufacturing and repair operations for shelters. The units were originally purchased between 2004-2005 directly from the original equipment manufacturer TDI and have remained inactive since that time. The contract will be awarded through a Purchase Order under FAR Subpart 13.302, with payment processed via Electronic Funds Transfer through the Defense Finance and Accounting Services.
