The Kerbodyne KR-2L Advanced Engine is an extra large liquid fuel engine which has a high specific impulse compared to the thrust. While the specific impulse is the same of the Rockomax "Mainsail" Liquid Engine in atmosphere, the I^sp in vacuum is higher than most of the engines, including the Mainsail and Rockomax "Skipper" Liquid Engine. Only the LV-N Atomic Rocket Motor, Toroidal Aerospike Rocket, LV-909 Liquid Fuel Engine and Rockomax "Poodle" Liquid Engine are more efficient, but only have 10% (at most) of this engine's thrust.

This, and the fact that it allows attaching parts on both sides of the engine, make it a very useful engine for upper stages. Especially because the S3 KS-25x4 Engine Cluster is the only other extra large engine in 0.25 but doesn't allow attaching parts below the engine. It has the second highest thrust of all engines available.^[outdated]

Product description

“

This engine is Kerbodyne's first attempt at a super heavy lifting engine. Later models have been designed with multiple nozzles to prevent a single point of failure and reduce manufacturing costs.
