A submersible vehicle launch and recovery system comprises a grab comprising at least two arms capable of moving relative to each other, the arms being rotatable between an open position and a closed position, in which closed position the jaws of the arms are able to grip a handling feature on a submersible vehicle. The arms comprise attachment means so arranged that the arms tend to close when the system is suspended by the said attachment means, at least one arm comprising buoyancy means so distributed as to tend to open the said arm when the system is submerged.
