Gliderless gun

A gliderless gun is a spaceship gun that doesn't involve gliders. The most famous example is the period-44 MWSS gun, based on a glider gun by David Buckingham. Additionally, Dietrich Leithner created many gliderless spaceship guns, particularly those based on the twin bees shuttle.

There is no strict definition for what constitutes a gliderless gun. For example, solutions based on Herschel tracks may produce gliders, even though they aren't utilised in the reaction.
