An underwater mine warfare countermeasure system is disclosed in which an air cushion vehicle carries an acoustic transmitter for sending out an acoustic wave pattern capable of exploding mines having acoustic responsive detonators. The vehicle includes a transmitter retraction apparatus for raising and lowering the transmitter between a storage position located just beneath the vehicle and an operative position spaced remotely from the vehicle, and also from raising the transmitter through an opening in the vehicle for placing it in an access position on the vehicle. The vehicle also includes an air seal or pressure boundary assembly which normally forms an air-tight cover for the aforementioned opening while still permitting the transmitter to be deployed to the operative position and retracted to the storage position while the vehicle is on cushion, but which opens to permit removal of the transmitter to the access position when the vehicle is off-cushion. |

DETAILED DESCRIPTION The present invention substantially alleviates, if not altogether eliminates, the disadvantages of prior known vehicles utilized in mine countermeasure warfare, particularly those utilized in underwater mine countermeasure warfare.
The present invention is an underwater mine warfare countermeasure system which includes an air cushion vehicle having a platform, a blower system mounted on the platform for discharging air into an air chamber located beneath the platform, an air retaining skirt attached to and surrounding the platform for retaining a cushion of air in the air chamber at sufficient pressure to support the vehicle above the surface on which it normally rests, and means mounted on the platform for propelling the vehicle in a given direction when the vehicle is supported by the cushion of air.
The mine warfare countermeasure system further includes an acoustic transmitter for projecting acoustic waves over an extended distance from the vehicle, the waves being capable of exploding mines having acoustic detonators.
A hoist means is mounted on the upper surface of the vehicle platform for normally suspending the transmitter beneath the platform and for raising and lowering the transmitter between a storage position located just beneath the lower surface of the platform and an operative position which is submerged substantially beneath the vehicle.
The hoist means is also operative to raise the transmitter through an access opening in the platform to the upper surface thereof for manual access to the transmitter.
The retraction apparatus also includes a pressure boundary means mounted on the platform over the opening therein for alternately normally providing an air seal between the upper and lower surfaces of the platform when the transmitter is disposed beneath the platform in either the aforementioned storage and operative positions, and exposing the access opening in the platform when the transmitter is being raised to the upper surface of the platform for access to the transmitter
