Enceladus is a three (or two) stage Super Heavy-lift rocket designed with lunar crewed missions in mind. It's capable of work with Low-Earth Orbit rendezvous, most based on Constellation program missions style.

Specifications

Height: 106 m
Diameter: 10 m; 6.88 m (third stage)
Mass: 5,250 t
Thrust: 68 MN - 73 MN
Functional engines: 6 - first stage; 4 - second stage; 4 - third stage

Capacity

Two-stages configuration:

LEO: 170t
TLI: 35t

Three-stages configuration:

TLI: 80t

The addition of a Hydrolox highly efficient third stage provides the chance of launch heavier payloads to orbit that requires a lot of energy, while the powerful Kerolox first and second stages creates the opportunity to turn this rocket into a beast when we talk about LEO capacity.

Notes: You may encounter some problems with the tower interstage disconnecting from the rocket when you spawn it, so I recommend to increase inertia tensors on Hidden Properties, or just change cargo dimensions.

The rocket is already equipped with a simple Vizzy program just to made it off the pad. Click AG:1 ALS and it will start the show.
