About this opportunity
The Defense Logistics Agency Aviation has awarded a sole-source contract to GE Aviation Systems, LLC for C-5 Regulated Transformer Rectifier Unit (RTRU) 400 AMP components (NSN 6120015249044UC, PN 716340-1) on September 25, 2026, under contract SPRWA1-26-D-0007.
The justification invokes FAR 6.302-1, only one responsible source, based on the part's military-unique design and proprietary nature. Market research through a Sources Sought Synopsis posted to SAM.gov on August 14, 2025 identified two potential vendors; both were determined incapable due to lack of access to proprietary technical data. A Cost Breakeven Analysis determined that reverse engineering would not achieve savings until 2043, making sole-source procurement the least costly alternative. Reverse engineering and competitive acquisition would delay critical spares by 4–6 years and potentially cause C-5 fleet grounding. GE Aviation Systems, LLC, classified as a large business, is the sole approved source on Source Control Drawing 4B99005.
The contract is structured as a five-year Requirements Indefinite Delivery Contract with Firm Fixed Price terms, consisting of five one-year ordering periods from June 15, 2026 through June 14, 2031. The requirement spans 60 units: two in Year 1, 28 in Year 2, and 10 each in Years 3–5. The RTRUs provide regulated +28 Volts DC at 400A maximum and support the C-5 aircraft sustainment life cycle through 2040. GE Aviation Systems, LLC is located at 1000 Macarthur Memorial HWY, Ronkonkoma, NY 11779-6026.
