The aircraft was fitted with a similar inverted tailplane to the W.12 in order to give unobstructed fields of fire to the observer, who was seated in a rear cockpit, immediately behind the pilot.

In order to compensate for the increased size and weight over the W.12, the W.19 was fitted with a more powerful Maybach Mb.IV engine.

Production aircraft were armed with one or two synchronised 7.92 mm (.312 in) LMG 08/15 machine guns firing forward and a single 7.92 mm (.312) LMG 08/15 machine gun for the observer.

Combats often occurred between the various Hansa-Brandenburg fighters and large British flying boats such as Felixstowe F.2s and Curtiss Americas.
