the United States Navy has sent some of its own submariner officers to undergo the 'Perisher', in order to foster and maintain closer links with the Royal Navy. In 1995 the Royal Netherlands Navy took over the Perisher course for diesel-electric submarines, since the Royal Navy no longer operates boats of that type. The course is attended by candidate submarine commanders from navies around the world. Traditions The Submarine Service has many traditions that are not found in the surface fleet. These include slang unique to submariners (such as referring to the torpedo storage compartment as the Bomb Shop and the diesel engine room as the Donk Shop), a special communications code known as the Dolphin Code and the entitlement of a sailor to wear Dolphins and black cap covers upon entering the service. These are only awarded after completion of training and qualification in ships' systems during the first submarine posting (Part III training). The Jolly Roger and the Submarine Service Rear-Admiral Arthur Wilson VC, the Controller of the Royal Navy, has gone down in history as the officer who claimed in 1901 "[Submarines are] underhand, unfair, and damned un-English. ... treat all submarines as pirates in wartime ... and hang all crews," In fact he had advocated the purchase of submarines the year before, and he was actually expressing a desire to continue the policy of discouraging foreign powers from building submarines while the Royal Navy developed its own in secret. The legend goes that in response to these top secret remarks of Wilson's made 13 years earlier Lieutenant-Commander (later Admiral Sir) Max Horton first flew the Jolly Roger on return to port after sinking the German cruiser and the destroyer in 1914 while in command of the E-class submarine . In World War II it became common practice for the submarines of the Royal Navy to fly the Jolly Roger on completion of a successful combat mission where some action had taken place, but as an indicator of bravado and stealth rather than of lawlessness. For example, in 1982 returning from the Falklands conflict flew the Jolly Roger depicting one dagger for the SBS deployment to South Georgia and one torpedo for her sinking of the Argentinian cruiser General Belgrano. The Jolly Roger is now the emblem of the Royal Navy Submarine Service. Dolphins Badge First officially adopted in the 1950s, qualified submariners are presented the Golden
