In addition to Remus mentioned by LW above, it may be of interest here to note that the RN has been transitioning to a joint Franco British vehicle called the MMCM (Maritime Mine Counter Measures) programme. The 'mothership' for these USVs is the RFA Lyme Bay which is currently in Gib but a week ago was in the Channel.
I suspect that some of the USV component are already in the Gulf.
