c/10 orthogonal is an orthogonal speed that is equivalent to one tenth of the speed of light.

Spaceships

On March 5, 2016, zdr discovered the first c/10 orthogonal spaceship, copperhead.

On March 20, 2016 Simon Ekström found the fireship with a large spark using the copperhead's front end. Tanner Jacobi noticed that two of them can support a tagalong identical to the back end, allowing to stack them. Two years later, AforAmpere discovered cottonmouth, an extensible pushalong for the copperhead.

A Caterloopillar can theoretically be configured to move at c/10, but there are technical difficulties with speeds of the form c/(4n+2), and as of the end of 2017 this has not been done in practice.

Puffers and rakes

Nico Brown constructed a fireship-based c/10 puffer and a rake on the same day. More constructions were done by Christoph Reinthaler and GilGil, which can be found at External links below.

Guns

A copperhead gun was completed one day after the discovery of the ship. Stable signal converters starting from a glider were constructed by Goldtiger997 that made a p197 copperhead gun and a p387 fireship gun possible.
