# Rotating-Detonation Hypersonic Engines GE Aerospace And Lockheed Martin Demo Dual-Mode Hypersonic By Kanesa David | Written with AI assistance | Published 2026-02-02 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/GE-Aerospace References: [newatlas](https://newatlas.com/military/rotating-detonation-hypersonic-missile/) & [geaerospace](https://www.geaerospace.com/)  GE Aerospace and [Lockheed Martin](https://www.trendhunter.com/trends/wildfire-management) collaborated on a liquid-fueled rotating-detonation ramjet (RDRJ) designed to improve the efficiency of hypersonic missiles. The demonstrator engine uses a rotating detonation core, featuring a supersonic combustion wave that circulates within an open-ended cylinder to sustain pressure and reduce fuel use. This approach aimed to address the so-called efficiency gap that has limited current hypersonic propulsion. The RDRJ concept combined a compact rotating-detonation engine with Lockheed Martin’s high-speed tactical inlet for dual-mode ramjet operation. In practice, the system can function as a ramjet at supersonic speeds and transition to a scramjet configuration at hypersonic velocities. Because the rotating-detonation core can operate from subsonic up to hypersonic regimes, it reduces the need for oversized rocket boosters and allows for a lighter overall propulsion package. For defense stakeholders, this engine architecture matters because it supports extended range and extreme speeds without proportional cost or size increases. The simplified construction and dual-mode flexibility point toward hypersonic systems that can be produced at greater scale while remaining adaptable to different altitudes and mission profiles. This positions rotating-detonation ramjets as a key signal in next-generation missile design, emphasizing efficiency and mass manufacturability over one-off experimental platforms.
