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 Isp 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 0.23.5 but doesn't allow attaching parts below the engine. It's has the second highest thrust of all engines available.[outdated]

Manufacturer's 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.
