The Coe ship is a period-16 c/2 orthogonal spaceship that was discovered by Tim Coe in October 1995. It works as a puffer engine because it produces a long spark behind it as it moves.
Despite its small size, it never appeared in a soup until 2015 when apgsearch was devised. By doing so, it became the first naturally occurring non-period-4 spaceship to occur in Life out of an asymmetric random starting pattern.[1] A second Coe ship appeared in June 2016. However, the Schick engines and the copperhead have appeared in symmetric soups.
