The Department of Defense, through the Naval Surface Warfare Center Crane Division, is issuing a Request for Solutions (RFS) for the Multi-Service Advanced Capability Hypersonic Accelerator (MACH-XL 26) project, focusing on affordable near-hypersonic and hypersonic all-up-rounds (AURs) and flexible launcher platforms. This initiative aims to address significant challenges in affordability and scalable production capacity for advanced hypersonic systems by conducting focused testing and demonstrations to identify cost-effective solutions and reduce production risks. The project is part of the Strategic & Spectrum Missions Advanced Resilient Trusted Systems (S2MARTS) consortium, and interested parties must be members of this consortium to respond. For further details, including membership information, interested parties can visit the S2MARTS website at https://s2marts.org/ and may contact Ethan Dale at ethan.w.dale.civ@us.navy.mil for inquiries.
