PROBLEM TO BE SOLVED: To resolve a fault found in the prior art multiple string installed rocket ammunition launcher that it shows a poor balancing for support and relative high-speed operation has been difficult due to the fact that a rear end part of a cage is applied as a turning center for its derrick operation.SOLUTION: This invention relates to a multiple string installed rocket ammunition launcher L in which a cage 1 having a plurality of rocket ammunitions stored therein is arranged in such a manner that it can perform derrick operation. In this invention, there are provided a fixed arm 3 arranged at a base 2; a cage articulation part 4 arranged at a side part of the cage 1 to determine a turning center of the derrick operation; a derrick operation mechanism 5 for operating the derrick operation of the cage 1; a support arm 6 of which a base end part is rotatably connected to the fixed arm 3 and of which an extremity part is rotatably connected to the cage articulation part 4; and an ascending or descending cylinder 7 for connecting the base 2 with an intermediate part of the support arm 6. The cage 1 is enabled to be supported under a well-balanced state to realize high-speed operation.SELECTED DRAWING: Figure 1
