This page is an equivalent to the Spaceship Search Status Page, albeit for 2x2 instead of Life.
Known spaceships by width
The majority of spaceships shown as upper bounds are from LaundryPizza03's updated version of David Eppstein's glider database.[1]

Note by DroneBetter: From the previously-included (1,1)c/3 entry, it appears that unlike LifeWiki:Spaceship Search Status Page (which considers the maximum orthogonal width of the pattern itself), this page measures diagonal spaceships by the number of cells in an orthogonal ray through the footprint left in their wake (corresponding with half-diagonals of width perpendicular to travel direction). The other diagonal speeds are measured accordingly.
| Spaceships of speed c/2, 2c/4,[2] 2c/5, c/3, 2c/6,[2] c/4, c/5, c/6,[2][3] c/7,[4] 2c/38,[5] (1,1)c/8, (1,1)c/4 and (1,1)c/3. (click above to open LifeViewer) |
Notes
- ↑ was found by Josh Ball on November 5, 2015[2], width 26 has been disproven with qfind but it crashes at 28, so not guaranteed to be of minimal length, but is of minimal width so counts as a green
