Budget estimate

$300,000 – $2,000,000

The contract’s total value is not disclosed, but based on typical unit costs for specialized aerospace cylinder assemblies (often $10k–$50k per unit) and the best‑estimated quantity of 34 units, the likely award range is roughly $300,000 to $2,000,000. Lower end assumes modest unit cost and minimum quantity; upper end assumes higher unit cost, full quantity, and added engineering/quality‑assurance fees.
