As its name suggests, this only costs 40,000, depending on the payload mass. In this case, it can lift 10 tons up to high Kerbin orbit, while still recovering the first and second stages. It costs 20% less than the 'Standardized Reusable Booster,' and, while taking 25% more payload mass, end up with 200-300 m/s more dV. DLC required.​
