BrazilianEngines is a mod for Kerbal Space Program with Realism Overhaul and RP-1, which adds a collection of Brazilian rocket engines, real and fictional, powered by liquid and solid propellants, inspired by Brazil's space program.
BrazilianEngines brings engines inspired by Brazil's space program, combining historical designs with fictional creations that celebrate Brazil's aerospace potential. This is a version in development that seeks to honor the legacy of the national space program and, in particular, the 21 heroes of Alcântara.
This mod is designed to work with Realism Overhaul and Real Solar System, offering a realistic space exploration experience in KSP.

This mod is dedicated to the 21 heroes of Alcântara, whose lives were lost on August 22, 2003, in pursuit of advancing Brazil's space program. Their sacrifice inspires this project and our mission to celebrate Brazil's aerospace history.
We thank the KSP community, the developers of Realism Overhaul, and the ROEngines team for the resources that made this mod possible.
