A three-stage rocket featuring each of the default parts as of 0.8.5

This page lists the rocket parts that are included with the latest paid version of Kerbal Space Program, currently 0.17. These parts are also called vanilla parts, default parts, and stock parts.

For a list of all the parts available in the demo version of Kerbal Space Program, look at the demo parts page.

Units are given as Newtons (N) and Kilograms (kg), but there is likely a scaling factor involved. As long as your scaling factor is applied equally to all measures, the math will work just fine, so if you prefer, you can think in terms of metric tons and kN.

To reduce confusion, specific impulse is given in both velocity and time units. Please see the discussion page for further reading on ways of expressing specific impulse.
