Solicitation / RFP / RFQ

This solicitation, "Carbon Crunch," issued by the Defense Advanced Research Projects Agency (DARPA) Tactical Technology Office (TTO), aims to enable scalable, fast, and agile production of hypersonic aeroshells. The program seeks to accelerate carbon-carbon (C-C) hypersonic aeroshell production by developing and applying innovative manufacturing methods that are inherently faster and more scalable. The goal is to demonstrate an end-to-end manufacturing process from raw materials to near-net-shape densification, achieving high quality, rapid production, and quick design-cycle turnaround. The technology developed is intended for transition to hypersonic programs of record.

• Develop a new integrated process for producing C-C aeroshells.

• Demonstrate high-rate production of C-C aeroshells.

• Demonstrate process agility for switching designs with minimal downtime.

• Assemble teams to demonstrate the entire aeroshell production process, from preform layup to near-net-shape aeroshells.

• Focus on reducing the time to densify C-C material and the associated manual labor.

• Scope includes the aeroshell and potentially hot structure portions (e.g., leading edge, nosetips).

• DARPA is NOT interested in novel thermal protection system materials, technologies for cooling, parallelizing existing processes, processes reliant on touch labor, or final machining methods.

• Type of instrument: Other Transaction (OT) for Prototype Agreement.

• Cost sharing may be required.

• Estimated period of performance (PoP) start: October 2026.

• Key Dates:

  • Final Solicitation Posting Date: January 30, 2026
