A shutter for a launch tube (3) for launching a countermeasure (4), wherein a support (10) has a circular opening (12) of a diameter (D) equal to the diameter of the launch tube (3). The shutter has a first and second flexible panel (15, 16) fitted to the support (10) and which, when undeformed and at rest, close the circular opening. The panels (15, 16) flex and deflect, as a front end portion (6) of the countermeasure (4) moves through the circular opening (12), to permit expulsion of the countermeasure (4) through the shutter (1), which is opened by the forward movement of the countermeasure. |
