GE Aerospace, Lockheed Martin validate liquid‑fueled rotating detonation ramjet for hypersonic missiles

GE Aerospace and Lockheed Martin completed a series of tests demonstrating a liquid‑fueled rotating detonation ramjet as a viable, compact propulsion option for hypersonic missiles. The campaign, the partners' first under a broader joint technology development arrangement, showed improved fuel efficiency and potential for longer‑range Mach‑5+ flight.

Briefing

What Hype is tracking

  • Validates a compact, liquid‑fueled rotating detonation ramjet as a fuel‑efficient propulsion option for Mach‑5+ missiles, demonstrating a clear path to extending range and endurance and aligning with Lockheed's broader rotating‑detonation investments (source:36c3433a-2591-477a-8cc2-7fb4885d18bc).
  • The tests are the partners' first under a joint technology development arrangement and advance alternatives to current hypersonic propulsion approaches, supporting accelerated prototyping of hypersonic all‑up rounds (source:fd44f8e5-fd00-42f7-97dd-5085da47c945).
  • Adds to a series of recent propulsion hot‑fire milestones that de‑risk high‑performance powerplants needed for next‑generation weapons and platforms, underscoring the DoD push to speed propulsion development (source:3293b6db-a761-40fb-b9d7-4652f47a897e).
