Need to rehabilitate this question. It would allow me to ask new questions on this site.

This is a new subject for Space Industry – heavy spacecraft (1200-ton) in LEO that have to burn hundreds of tons of propellant to get going to their destination.

It looks inefficient to launch 7+ fuel tankers just to fill up SpaceX Starship in LEO and then burn 40% of Starship’s fuel in a first orbit change.

Could a light space tug with expendable solid fuel boosters assist Starship in LEO?

Solid rocket fuel has all kinds of disadvantages compared to a liquid fuel.

But would solid fuel have an advantage in the case of a light space tug (less than 5 tons dry mass) with a small liquid engine and attachments for a large solid rocket boosters (expendable)?
