Boreal is a high-performance rocket designed to carry large amounts of mass to high Earth orbits in addition to Earth Escape missions. It can be configured in two versions, the BL2S version, intended for missions that require less performance and the BL4S version, intended for missions that require high performance and ?v. When I made this rocket I thought about making it as close to reality as possible, so you will see some things if you access the internal parts of the rocket.

In addition to the Boreal, this craft also has a geostationary satellite intended for high-performance communications. InterSat 1A has engines to help correct the orbit but it is just an aesthetic satellite, I didn't get to delve into its usability. I also didn't get to make a launch tower as I didn't find one that suited this craft well. Feel free to make one and share in the future.
