Frankfurt is a prototype river icebreaker constructed by Hitzler Werft for icebreaking duties on the Elbe River, Oder River, and canals in Germany, operated by the Wasser und Schifffahrtsamt Eberswalde.[2] She was built in 2002. Three further vessels, built to a similar design, were ordered by the Wasser und Schifffahrtsamt in 2009.

As the lead ship of her class, models of the Frankfurt underwent testing in a large ice-tank laboratory.[2] She cost 4.2 million euros.

Her design features a pair of diesel generators that power electric motors that actually drive the propeller.[3] The use of a diesel-electric system provides a "good torque curve", and eliminates the need for a bulky gearbox. The electric motor can consume up to 700 kilowatts (940 hp) She has a third "harbor diesel" of 15 kilowatts (20 hp).
