About this award

The Defense Advanced Research Projects Agency (DARPA) awarded a $2.95 million cost-plus-fixed-fee definitive contract to Lockheed Martin Aerostructures (a subsidiary of Lockheed Martin Corporation) on February 12, 2021, for the High Enthalpy Aperture Technology (HEAT) program, with completion targeted for February 29, 2024. This contract supports DARPA's mission to develop innovative aperture materials and enabling technologies capable of withstanding extreme thermal and dynamic pressures in hypersonic operational environments. The award stems from a pre-solicitation opportunity posted in March 2020, which sought proposals for new radio frequency and infrared aperture materials to advance hypersonic flight capabilities. Performance will be conducted in Orlando, Florida, with no small business set-aside designation applied to this acquisition.

Under the Phase I effort, Lockheed Martin will conduct research and development activities including demonstration of materials meeting specified performance metrics, with ground testing scheduled at month 21 to evaluate materials in simulated hypersonic flight conditions. The contract structure provided flexibility for optional Phase II extensions, which would have allowed the total program value to reach up to $3 million should the government exercise follow-on development activities. This investment in advanced aperture technologies aligns with DARPA's broader hypersonic systems development portfolio and supports the Department of Defense's strategic technology modernization objectives in high-speed flight domains.
