摘要

A naval vessel countermeasure launching device having a launch tube (2) for launching a countermeasure (3); a cylinder (5) of pressurized gas; and a feed system (7) for feeding gas from the cylinder to the launch tube (2). A shutter of the feed system has a supporting body (32), and a cup-shaped body which slides with respect to the supporting body and has an annular end portion (42) for closing a gas feed opening (28) to the launch tube; and the supporting body and the cup-shaped body define a variable-volume inner chamber (47). The shutter (30) is housed in a seat (24) into which pressurized gas from the cylinder is fed so that the gas exerts pressure on at least part of the cup-shaped body. When the chamber is depressurized, the gas pressure on the cup-shaped body slides the cup-shaped body on the supporting body to open the shutter.
