The engine was a core component of a spaceship, akin to a human's heart. Without a healthy heart, there was no way a body could sustain high-intensity work.
All the components which were going to be used in the restoration of the naval-issued Eagle-class frigate must be of the highest standards, so the engine of course was no different.
The Black Mamba 130 engine was built by one of the top components manufacturers in the alliance, Dark Sky Serpent Corporation. The standard frigate engine could generate a propulsion force of around a hundred standard units, while a Black Mamba 130 engine could generate up to a hundred thirty standard units of propulsion force through an optimized mechanical structure and power system, a thirty percent increase compared to the standard frigate engine.
