The award was issued on July 15, 2026, under solicitation SPE7M4-26-T-103T, and the items are to be delivered to DLA Distribution Red River in Texarkana, Texas, within 165 days of the order being placed, with an implied deadline of December 28, 2026.

All supplies must comply with strict packaging standards including ASTM D3951 and DLA’s RP001, and must be marked and labeled per MIL-STD-129, which mandates bar-coded identification with specific data from the purchase order, including the unit of issue and quantity per unit pack. Inspections and acceptance occur at the destination by government representatives, and compliance with the DLA Master List of Technical and Quality Requirements is enforced. The contractor is required to invoice exclusively through WAWF, using web entry, EDI, or FTP, and is bound by clauses covering veteran employment reporting and sustainable product use, both modified by DLA deviations. Southern Cross Aviation, LLC has certified as a Small Business, Small Disadvantaged Business, and Women-Owned Small Business, triggering compliance with FAR 52.219-28 and other small business reporting obligations. The solicitation does not include options, evaluation factors, key personnel requirements, or security clearances, and the award appears to follow a Lowest Price Technically Acceptable approach based on adherence to technical and packaging requirements.
