Schick engine (or Schick ship) is an orthogonal c/2 spaceship that was found by Paul Schick in 1972. Alternatively, it may refer just to the tagalong (displayed in green) that is attached to the back of the two lightweight spaceships. The tagalong may also be attached to the back of two middleweight spaceships, two heavyweight spaceships, or a lightweight spaceship and a heavyweight spaceship.

Its eleven-cell rear spark can be perturbed by other c/2 spaceships to form a variety of puffers and thus it is a puffer engine.

The Schick engine first appeared naturally on 12th February 2019, having previously emerged (along with its middleweight and heavyweight variants) from symmetric soups on Catagolue.
