The Da Vinci SSTO

One of the ESA's most agile and capable space drones. Currently, six are in operation, taking turns to deliver supplies to the European Space Station Dawkins, as well as other contracted orbital missions, such as the Indian Swaraj space laboratory.

Da Vinci drones are very light, weighing only one tonne, but they are very fragile. They also don’t have much payload capacity, which is why they usually just deliver food packages and other small supplies. They use RAPIER engines and monopropellant orbital motors.
