San Bruno, Calif. – September 13, 2026 -- Chariot Defense, a maker of software-defined power distribution systems for the battlefield, has appointed four defense and venture capital veterans to its Board of Advisors, following a $34 million Series A round led by Andreessen Horowitz and a $7.4 million contract with the Pentagon's Department of War Innovation Unit (DIU).
Los Angeles – September 13, 2026 -- Hermeus is developing Ramjet-X, an expendable, ramjet-powered test vehicle designed to be launched from its reusable Quarterhorse aircraft, aiming to make high-Mach airbreathing flight testing cheaper and more repeatable.
Ramjet engines require substantial initial speed before they can operate, historically forcing test programs to rely on large, expensive, single-use boosters. Hermeus instead uses its reusable Quarterhorse aircraft to accelerate Ramjet-X to the required speed and altitude before release, after which the vehicle enters ramjet-powered flight while Quarterhorse returns for subsequent missions.
