The contract solicitation W911PT26QA093 seeks 4340 alloy steel bars, square in cross-section, complying with SAE AMS6414/6415/6484 specifications, for use in the 155mm M284 cannon. The material must be 9.00 inches plus 0.125 inches on each side, with a minimum length of 10.00 feet and maximum of 12.00 feet, in one-foot increments only. The steel must be normalized or annealed, excluding merchant quality and free-machining grades, prohibiting flame cutting or cutting from plate. Each bar must have specific heat lot numbers stamped if multiple heats are involved, and final draw/tempering temperature data must be included in the certified test report package. The solicitation is a total small business set-aside under NAICS code 331110, requiring offers to be submitted electronically by June 24, 2026, at 4:00 PM local time to Amanda Robinson at the Watervliet Arsenal. The contract is awarded on a firm fixed price basis with delivery required within 90 calendar days of award to the specified Watervliet, New York location under F.O.B. destination terms, with the contractor responsible for all transportation costs. On-time delivery is deemed very critical, and failure to meet deadlines due to raw material shortages, subcontractor delays, or scheduling conflicts is not an acceptable excuse. The contractor must comply with rigorous quality and inspection controls, including preparation and submission of a Special Process Plan (SPP) as part of the first article inspection, adherence to MIL-STD-130 and MIL-STD-129 for item marking and shipment labeling, and the use of machine-readable identification compliant with Appendix A of MIL-STD-130. Inspection criteria require use of DD Form 250 and DD Form 1155 with accompanying Certificate of Conformance and Certified Test Report for each shipment, though these documents alone cannot serve as the sole basis for acceptance without government approval. Testing equipment must meet ANSI Z540-1 and ISO 10012-1 standards and maintain accuracy within 10% of the total tolerance. Security requirements include compliance with Army Directive 2014-05 for background adjudication, potential non-disclosure agreements, and adherence to Controlled Unclassified
