> How would that work?

Kinetic bombardment is possible by launching a satellite with (for example, since its a popular description) heavy tungsten rods, that are parked in orbit. The launch can be years ahead, and disguised as a communications hub.

The satellite can “shoot” at targets from orbit. A rod carries no explosives, and is hard to stop.

The speed due to falling/gravity makes the kinetic impacts huge, its basically small asteroids.

They can even be guided, like the landing boosters.

And to go full circle: the concept of aero-flaps on Falcon-9 (and later Starship Booster) was inspired by designs for falling guided bombs, where fins did not perform at the speeds achieved.
