Sintavia awarded GAMMA-H hypersonic development contract by U.S. DoD
Focusing on additive technology for next generation hypersonic propulsion systems
The U.S. Department of Defense has awarded Florida-based Sintavia, LLC, an all-digital aerospace component manufacturer, a contract to develop additively manufactured hypersonic propulsion components. The contract is part of the Growing Additive Manufacturing Maturity for Airbreathing Hypersonics, or GAMMA-H project.
By validating these processes specifically concerning hypersonic propulsion components, Sintavia’s efforts under GAMMA-H will be able to be used across the growing hypersonic industrial base. The contract is expected to run through 2025.
“The GAMMA-H award represents an important step forward in developing and formalizing standard additive manufacturing processes that can be used across the industry for hypersonic production,” said Brian R. Neff, Sintavia’s Founder & CEO. “As the industry leader in this effort, Sintavia is uniquely positioned to work with the GAMMA-H project to successfully develop and validate these processes. We are grateful to the GAMMA-H team for their trust in Sintavia regarding this absolutely critical national security imperative.”
Announced in October 2023 with a budget of $106.7M, the GAMMA-H project is a joint effort between the Office of Secretary of Defense ManTech and the Naval Surface Warfare Center, Crane Division. In addition to the direct award, Sintavia supports several other efforts also funded by the project.
