What he was on about and got the name wrong were,,,,,,,

The Oberon class was a 27-boat class of British-built diesel-electric submarines based on the successful British Porpoise-class submarine.

Thirteen were constructed for the Royal Navy, while another fourteen were built and exported to other countries' navies: six to the Royal Australian Navy, three to the Royal Canadian Navy with an additional two British submarines later transferred, three to the Brazilian Navy, and two to the Chilean Navy.

As of 2006, at least fourteen Oberons are confirmed to have survived in some form: Seven as museum boats or tourist attractions, two preserved in partial form as monuments, while five are to be converted into museum boats, or are otherwise awaiting disposal.
