Low energy track

A track useful for guiding a projectile having no wheels along a launching trajectory. The track comprises: an elongate track base extending parallel to the trajectory and a plurality of spaced supporting members, each rotatably carried by the elongate track base. Each supporting member carries an upstanding columnar finger laterally positioned on the supporting member so that a top portion thereof may intersperse with columnar fingers on adjacent supporting members. A projectile seated on a columnar finger will be continuously supported on adjacent columnar fingers as it moves along the trajectory. The supporting members rotate forwardly in turn, first moving to a supporting position perpendicular to the track base, and then, continuing to rotate forwardly, to a lower non-supporting position where the projectile is supported on the next perpendicular columnar finger.
