Abstract: A line throwing rocket arrangement is disclosed which is normally stored in a generally rectangular case. The set includes at least one rocket provided with a guide sleeve generally integral with the body of the rocket but disposed exteriorly thereof. During the launching, the sleeve slides over a straight guide rod. The storage case is provided with suitable means for securement of the guide rod to the box at different angles so that different ranges can be covered by the rocket in rescue or the like operations can be covered. The advance in the art is primarily in the simplified arrangement which facilitates the operation and reduces the manufacturing costs of the set.
