Figures from Launch Library 2; engines and propellant as written in the Wikipedia article Astra Rocket 4, by Wikipedia contributors, under CC BY-SA 4.0. A dash means it has no value for that rocket yet; thrust-to-weight and cost per kilogram are worked out from its figures. Launch costs are rough public estimates and can be years old. Cost per kilogram divides the price by the most the rocket can lift to low orbit: that maximum is usually for a version that throws its boosters away, while the price is often for one that lands them, so read it as a best case. Total cost is the fairer comparison. The drawings are to scale but simplified: boosters and fairings follow rounded public figures.
