Abstract

Autonomous underwater vehicles are described that are stackable with other like autonomous underwater vehicles on a suitable launch platform, such as within a vertical missile launch tube of a submarine, waiting to be deployed into the water. The underwater vehicles can be deployed or launched individually, in groups, or all together into the water. While stacked together, the stacked autonomous underwater vehicles can connect to one another or to external structure of the launch platform. In addition, the underwater vehicles can be positively buoyant or can be made to have controllable buoyancy to allow the underwater vehicles to float up and out of the launch platform during deployment without an external deployment force.

First claim

The invention claimed is:

1. A vertical missile launch tube of a submarine, comprising:
an interior space with a vertically uppermost exit opening;
a plurality of autonomous underwater vehicles within the interior space in a vertically stacked arrangement, each one of the autonomous underwater vehicles has a maximum lateral dimension that is larger than a maximum thickness dimension thereof, and each one of the autonomous underwater vehicles is sized to permit each autonomous underwater vehicle to exit the interior space through the vertically uppermost exit opening; and
an actuatable, releasable connection mechanism on each one of the autonomous underwater vehicles that releasably connects each one of the autonomous underwater vehicles to the vertical missile launch tube.

2. The vertical missile launch tube of claim 1 , wherein there are at least three of the autonomous underwater vehicles in the vertically stacked arrangement.

3. The vertical missile launch tube of claim 1 , wherein each one of the autonomous underwater vehicles has positive buoyancy.

4. The vertical missile launch tube of claim 1 , comprising a sleeve within the interior space, and the autonomous underwater vehicles are disposed within the sleeve.

5. The vertical missile launch tube of claim 1 , wherein each one of the autonomous underwater vehicles includes a vertical thruster.

6. A submarine, comprising:
a hull;
a vertical missile launch tube in the hull that defines an interior space with a vertically uppermost exit opening;
a plurality of autonomous underwater vehicles within the interior space in a vertically stacked arrangement, each one of the autonomous underwater vehicles has a maximum lateral dimension that is larger than a maximum thickness dimension thereof, and each one of the autonomous underwater vehicles is sized to permit each autonomous underwater vehicle to exit the interior space through the vertically uppermost exit opening; and
an actuatable, releasable connection mechanism on each one of the autonomous underwater vehicles that releasably connects each one of the autonomous underwater vehicles to the vertical missile launch tube.

7. The submarine of claim 6 , wherein there are at least three of the autonomous underwater vehicles in the vertically stacked arrangement.

8. The submarine of claim 6 , wherein each one of the autonomous underwater vehicles has positive buoyancy.

9. The submarine of claim 6 , wherein each one of the autonomous underwater vehicles includes a vertical thruster.
