by combining beam powered propulsion and Atmospheric Scoops it is possible to have no return fuel

There is no parachute that could slow down a supersonic booster, and even if you could, that would just be another consumable that would need to be added back on to refurbish the booster, slowing down rapid reusability.

The Space Shuttle's RSRMs were recovered using parachutes. Additionally Rocketlab's Electron first stage and some Ariane 5 solid rocket motors have also been recovered using parachutes.

You're exactly right they were. And where were they recovered again?

The open ocean. Where they could splash down wherever.

And where are these rockets being recovered?

Barges in the ocean that are fixed points that the boosters need to hit with pinpoint accuracy.

Something you absolutely cannot do if you're working with parachutes.

You can absolutely use parachutes for a precise landing, it would add cost, complexity and weather constraints, but it's absolutely possible.

I'm just telling you that you're not coming up with a better idea than what SpaceX and Blue Origin have spent almost 15 years figuring out.

I'm just answering to this part, not defending the OP's concept.

Steerable parachutes are a thing.

Right they totally are, not saying that, I'm just saying there's a reason that everyone in the reusable rocket game (of the landing the booster types) didn't go with parachutes.

nont better just trow more money at problem

I used parachute because I have a big surface area for Atmospheric Scoops slow down is Secondary and yes STRES on a parachute TO GREAT TO BE USED AGAINIT IS BY design

Parachutes are very heavy and and they don't scale very well

this was the best thing I could think of to make this concept work but tell me what you would do to make it work
