SMS Basilisk was an ironclad gunboat of the Wespe class built for the German Kaiserliche Marine (Imperial Navy) in the 1870s.
The ships, which were armed with a single 30.5 cm (12 in) MRK L/22 gun, were intended to serve as part of a coastal defense fleet.
Through the 1860s, the Federal Convention examined various proposals, which included plans to build at least eight vessels, to as many as eighteen armored warships.
The decision was finalized based on the fleet plan conceived by General Albrecht von Stosch, the new Chief of the Kaiserliche Admiralität (Imperial Admiralty), in the early 1870s.
He envisioned a fleet oriented on defense of Germany's Baltic and North Sea coasts, which would be led by the ironclad corvettes of the Sachsen class.
The ship was fitted with a waterline armor belt that was 102 to 203 mm (4 to 8 in) thick, with the thickest section protecting the propulsion machinery spaces and ammunition magazine.
