The '''KS-25 "Vector" Liquid Fuel Engine''' is a [[liquid fuel engine]] with a single nozzle. Despite being a size 1 part, it has a thrust and mass in between that of the size 2 Skipper and Mainsail engines. It has a relatively high thrust to weight ratio, moderate Isp, and extremely large gimbal range. More unusually, it is surface-attachable (like the Mk-55 "Thud"). These advantages are somewhat offset by its comparatively high tech requirements and cost.

The KS-25 "Vector" Liquid Fuel Engine is a liquid fuel engine with a single nozzle. Despite being a size 1 part, it has a thrust and mass in between that of the size 2 Skipper and Mainsail engines. It has a relatively high thrust to weight ratio, moderate Isp, and extremely large gimbal range. More unusually, it is surface-attachable (like the Mk-55 "Thud"). These advantages are somewhat offset by its comparatively high tech requirements and cost.

The KS-25 is a reference to the Space Shuttle Main Engines which are also named RS-25. This is likewise shown in that the part files are named variants of "SSME".

Product description

Kerbodyne's flagship engine, the KS-25 excels as a first stage engine through its high thrust-to-weight ratio and exceptional sea level efficiency. Kerbodyne engineers achieved this by running the engine in a staged combustion cycle and at extremely high chamber pressures. Special new alloys had to be invented to suppress the engine's tendency to become a bomb. The single version is designed with very durable components and high reusability, as well as higher gimbal range, but because of that is also heavier than its expendable counterpart used in first stage clusters.
