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 and its variants have not yet appeared naturally, but have emerged from symmetric soups on Catagolue.
