Submariners were originally dismissed as 'pirates' by Royal Navy brass because of their sneaky and very un-British ability to hide under the sea - not sporting don't you know! While the Silent Service still struggles for recognition because of the nature of their tasking (i.e., spying in various forms), they quickly proved their value during WW I and the first subs back into port after a successful mission, proudly flew the Jolly Roger. Thereafter, pirate rig (dressing for the less than savoury environment of a submarine) and hoisting the Jolly Roger has become a firm tradition. HMCS Ojibwa is taking a leaf out of that book and proudly hoisting the Jolly Roger whenever a submariner is at the boat.
