This patent discloses a submarine weapon launch system that uses an external impulse tank. A submarine has at least one cylindrical torpedo tube that has a breechward section residing within the pressure hull of the submarine and a muzzleward section residing outside the pressure hull. An impulse tank that is mounted outside the pressure provides impulse water to the breechward section of the torpedo tube. A hull insert encases a space about a portion of both the breechward and muzzleward sections of the torpedo tube. The hull insert provide for venting of the encased space to the impulse tank outside the pressure hull and for venting of the encased space to the breechward section within the pressure hull. The hull insert protects the torpedo tube from pressure hull distortions while the encased space transports impulse water from the impulse tank to the breechward section of the torpedo tube.
