US Air Force explores rotating detonation engines for mass munitions

Bottom line

The US Air Force is exploring combined-cycle rocket engines with rotating detonation (RDRE-CC) for the HAMM programme to produce high-speed, affordable mass munitions.

Why it matters

Advancements in RDRE-CC technology could significantly lower the cost and increase the production rate of hypersonic munitions, altering the strategic balance in high-end conflict scenarios and impacting NATO defense planning.

The US Air Force is investigating rotating detonation rocket engine technology (RDRE-CC) for the Hypersonic Attack Missile Modernization (HAMM) programme. This technology aims to enable the production of high-speed, affordable mass munitions, potentially revolutionizing the scale and cost-effectiveness of hypersonic strike capabilities. Prototype testing is expected within 36-48 months.
