Indefinite Delivery Contract SPE4A725D0365

S3 Aerodefense LLC, a small business aerospace defense contractor based in Glendale, Wisconsin, was awarded a single-award Indefinite Delivery Contract by the Defense Logistics Agency Aviation on September 10, 2025, with a ceiling value of $2.0 million and an ultimate completion date of September 8, 2028. The contract supports the procurement and manufacturing of a bleed air duct assembly (National Stock Number 1560-007805717) for the Galaxy C-5 Aircraft, encompassing parts procurement, manufacturing, inspection, testing, preservation, packaging, and shipping. The contracting agency anticipates this as a long-term supply relationship structured around a five-year base period. S3 Aerodefense's existing contract portfolio with the Defense Logistics Agency demonstrates established capabilities in aerospace components and maintenance, repair, and overhaul services across multiple military platforms, positioning the contractor to execute the technical and logistical requirements associated with this critical aircraft component.

The original market research opportunity, posted by Defense Logistics Agency Aviation on May 27, 2025, sought qualified contractors capable of managing complex supply chain and production planning requirements specific to the C-5 Aircraft bleed air duct assembly, including long-lead time parts procurement and potential diminishing manufacturing source mitigation. The procurement falls under North American Industry Classification System code 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and required interested parties to demonstrate organizational and technical capacity, financial resources, project management capabilities, and performance standards compliance. As the bleed air duct assembly is a critical thermal management component integral to C-5 Aircraft operational readiness, the award of this contract to S3 Aerodefense reflects the contractor's qualification to support Department of Defense sustainment and logistics operations through direct supply of specialized aerospace components manufactured to stringent government specifications.
