The LV-T45 Liquid Fuel Engine is an engine which requires fuel from external liquid fuel tanks, and must be either connected beneath them or be on the receiving end of a fuel line.


The LV-T45 is the first Liquid Fuel engine with thrust vector control, that allows eficient control of the rocket when it is most needed - during ascent and orbit correction burns. Despite having the same mass and fuel specific impulse as LV-T30 Liquid Fuel Engine, the more complex LV-T45 has slightly less thrust (and longer burn time at the same fuel amount), that makes it not the best solution for the first stages, so you could consider parallel ignition of several LV-T30 and LV-T45 at takeoff for maximised thrust without losing control.

Like LV-T30, the LV-T45 are not placeable on Radial Decouplers and are typically reserved as a main engine after liftoff. The LV-T45 must be directly below a non-empty FL-T500 Fuel Tank to produce any thrust.


The LV-T45 engine was considered another breakthrough in the LV-T series, due to its Thrust Vectoring feature. The LV-T45 can deflect its thrust to aid in craft control. All these added mechanics however, make for a slightly smaller and less powerful engine in comparison with earlier LV-T models.
