that is has successfully demonstrated the operation of a “rotary detonation engine” in space, a world’s first.

Such an engine uses a series of controlled explosions that travel around a circular channel at its base. The result is a massive amount of thrust coming from a much smaller engine using significantly less fuel — a potential game changer for deep space exploration, according to JAXA.

It's actually called a detonation rocket engine harnesting the shockwave to propel the vehicle instead of the expanding exhaust.

If you think about it, this detonation rocket system can radically change various heavy payload delivery systems that require beyond horizon view range at hyper-sonic speed that can carry a heavy payload like anti ship and surface targeting missiles. The engine is much more compact in design with less moving parts compared to conventional liquid fuel missiles like the tomahawk missiles.

Switching from a turbofan to a rotating detonation engine probably wouldn't result in weight reductions, unless the rotating detonation engine takes in atmospheric oxygen (but then it wouldn't be a rocket)
