Abstract
Abstract A man transportable rocket launcher including a pair of telescoping secti, launch tubes, which are telescoped when being transported and extended for launching of the rocket. The warhead of the rocket always rides on the inner surface of the front tube which is carried inside the rear tube. Retention means cooperate with the fins to assist in retaining the rocket fins in folded position in the launcher prior to rocket launch. The retention means is moveable, with the rocket in the rear tube, for a predetermined length of travel of the rocket at which time the fins are released by the retention means and engaged by the inner surface of the front tube.
