**c/7 orthogonal** is an orthogonal speed that is equivalent to one seventh of the speed of light.

## Spaceships

On February 17, 2013 Josh Ball discovered the first c/7 orthogonal spaceship, the loafer.

Using caterloopillar technology, Michael Simkin constructed a c/7 orthogonal ship on April 16, 2016.^{[1]}

On February 4, 2017, Matthias Merzenich discovered the 339P7H1V0, a large p7 width-19 bilaterally-symmetric c/7 orthogonal spaceship. These ships can be chained by nontrivial spark interactions to produce an infinite number of distinct c/7 orthogonal spaceships.^{[2]}

## Guns

Loafer can be synthesized from 8 gliders, allowing the construction of guns.
