Precision Angle Block Set Manufacturing

The contract requires the manufacture and delivery of ten fully assembled precision angle block sets, each containing blocks calibrated in degree, minute, and second increments, and housed in protective cases designed to ensure safe transport and storage. Every set must meet an exacting tolerance of ±1 arcsecond accuracy, demanding advanced manufacturing techniques and rigorous quality assurance protocols to guarantee optical-grade precision across all components. The blocks must be engineered for long-term stability and minimal thermal expansion to maintain calibration under operational conditions. The effort is classified as a subcontract under NAICS code 332215, issued by the Department of Defense through its W6QK Acc-rsa office, with performance required at Redstone Arsenal, Alabama, 35898. Interested parties must submit responses by 9:00 PM Eastern Time on May 15, 2026, following the solicitation posted on April 29, 2026. There is no set-aside designation, and while no point of contact is listed, all submissions must comply with the technical specifications and delivery schedule outlined in the requirements, with no allowances for deviation from the ±1 arcsecond accuracy standard.
