The Basic Jet Engine is an air-breathing engine which uses liquid fuel and intake air.


This engine cannot function effectively at a height of much more than 10 km, but it is much more efficient to use jet engines in the lower atmosphere. The basic jet engine works at full power while stationary, whereas the TurboJet Engine won't get up to full power until it reaches 1000 meters/second surface velocity. This makes it ideal for low-flying aircraft, as the engine has a thrust of about 150 kilonewtons on the runway and an Isp of about 850. However, for high-flying aircraft, the TurboJet engine should still get you off the runway.

Note that currently, the only planets which these engines will work on is Kerbin, and Jool's moon Laythe.

Product description

A standard air breathing engine. This model utilizes limited range thrust vectoring. This engine works best at low cruising speeds and altitudes.

The designation “J-33 Wheesley” may be a reference to the real-life JT3D turbofan jet engine, also known as the TF33, made by U.S. aerospace company Pratt & Whitney which was involved with the Space Race.
