SMS Vulkan was a U-boat salvage tug in the Kaiserliche Marine laid down in 1907 and commissioned in 1908.

The famous U-boat commander Max Valentiner served as salvage officer on Vulkan in early 1911.

On 17 January 1911, he and the crew saved all 30 men from U-3 by rescuing them via a torpedo tube after it sank near Kiel harbour in Heikendorfer Bay because of an unclosed ventilation shaft valve.

At the end of World War One on 11 November 1918 the vessel surrendered to the British forces together with the larger salvage tug SMS Cyclop.
