The Real Cost of Late Deliveries in Aerospace Manufacturing

Aerospace procurement teams are working against a backlog that does not allow for missed deliveries. Boeing’s 737 MAX has nearly 5,000 unfilled orders as of March 2026, per Forecast International. The global commercial aircraft backlog now sits above 17,000 units across Boeing and Airbus, equivalent to nearly 12 years of current production capacity, according to IATA. Against that demand, BCG analysis puts the manufacturing cycle for aerospace casting and forging at 6 to 18 months, with delays of 12 months or longer when issues arise. STS Metals thinks in days and weeks. Stock items ship in as little as two weeks. Custom mill product runs on a schedule built around your commitment date, not an industry quoting window.

That gap comes from running operations differently than the rest of the industry. Many large mills schedule production to hit a revenue target, which could mean overbooking capacity, running lean on raw inventory, and stretching delivery dates when the queue gets long. STS is built around the customer commitment date. We schedule production to meet it. We carry strategic raw material inventory so we can respond in days rather than months. And we control the manufacturing process across seven facilities in the US and France, which lets us flex the schedule without waiting on a chain of outside suppliers.

That difference shows up in your total procurement cost, not just the unit price.

When deliveries are unreliable, procurement teams build defensive inventory. They order more than they need, earlier than they need it, in standard sizes that force machining waste. In titanium, buy-to-fly ratios often exceed 8 to 1, meaning more than 80 percent of a billet can end up as machined chips before the part leaves the factory, according to industry data published by Russell Finex. That waste compounds fast when material is over-ordered against unreliable lead times. Late deliveries also drive expedited freight, overtime labor, contractual penalties from end customers, and the administrative cost of managing a delinquent PO. IATA and Oliver Wyman estimated supply chain bottlenecks cost the airline industry more than 11 billion dollars in 2025 alone. None of that shows up on the original quote, but all of it shows up in the real cost of the program.

STS takes those line items off the table. Call us and you get a live person. Quote requests come back the same day. Orders go onto a schedule built around your commitment date, not ours. That is why Boeing extended its long-term supply agreement with STS in September 2025 covering titanium billet, bar, and plate for the commercial airplane portfolio. It is why Brown Europe was named a 2025 Collaborative Supplier by Rolls-Royce and Incora. Customers who need the program to run on time choose the supplier whose operations are built to do exactly that.

Most procurement teams still evaluate suppliers in the order of price, quality, and delivery. In aerospace, with backlogs this deep, that order has it backwards. Quality has to be there as a baseline. Delivery decides whether the program runs on schedule. And the supplier who shows up on time almost always wins on total cost anyway.
