SMS Adler was the third and final Habicht class gunboat built for the German Kaiserliche Marine (Imperial Navy) in the early 1880s. Intended to serve abroad, the ship was ordered as part of a construction program intended to modernize Germany's fleet of cruising vessels in the mid-1870s. The Habicht class was armed with a battery of five guns, and was the first class of German gunboat to use compound steam engines. The ship had a top speed of 11 knots (20 km/h; 13 mph).
