Abstract
Projectile launch apparatus () for use in a fluid environment. The apparatus () comprises a launch tube () having a supercavitating projectile () with cavitator () received within the launch tube (). A means for generating expulsion gas (not visible) is arranged to provide expulsion gas to propel the projectile () from the launch tube (), with means for bleeding expulsion gas () being provided to bleed a portion of expulsion gas around the projectile (). This allows expulsion gases to contribute to the formation of the gas cavity around the supercavitating projectile () as the projectile () is launched from the launch tube (). Particularly suited to the deployment of supercavitating projectiles underwater, such as in underwater mine disposal applications.
