The LV-T30 Liquid Fuel Engine is the first liquid-fuel engine available in career mode. It 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-T30 is the first liquid fuel engine with controllable throttle. This makes it very useful for precise, controlled maneuvers and conserving fuel. They are not placeable on Radial Decouplers and are typically reserved as a main engine after liftoff. The LV-T30 must be directly below a non-empty liquid fuel tank to produce any thrust. Even after introduction of the gimballing LV-T45 Liquid Fuel Engine, more powerful LV-T30 remained the best solution for the parts where power is more important than controllability, like the first liquid stage (however, in this case winglets or gimballing engines of a parallel stage are necessary for controlling the rocket)

Product description

Although criticized by some due to it's not unsignificant use of so-called "pieces found lying about", the LV-T series has proven itself as a comparatively reliable engine. The T30 model boasts a failure ratio below the 50% mark. This has been considered a major improvement over previous models by engineers and LV-T enthusiasts.
