An AUV is described that includes an external, deployable payload releasably attached to the exterior of the AUV. The release mechanism between the payload and the AUV is relatively simple and low cost. The payload is mounted external to the AUVs hull and does not significantly increase the cost of the AUV to which it is attached. There are no complex release mechanisms or intermediate launch systems attached to the AUV. Therefore, the described AUV can deploy payloads, such as sensors, that would normally be deployed from a manned platform. This can increase the payload capability of a small expendable AUV without increasing volume or cost of the AUV.
