Hansa-Brandenburg W.19

The Hansa-Brandenburg W.19 was a German fighter-reconnaissance aircraft of World War I.

It was a single engined two  seat biplane floatplane, and was a larger development of the successful W.12.

It served with the Imperial German Navy during 1918.

The W.19 was of similar layout to the W.12, but considerably larger (i.e. with a 2.6 m/8.5 ft greater wingspan and a 1 m/3.3 ft greater length).

It was a single engined tractor biplane, with two bay wings.

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.

One aircraft was fitted with a 20 mm Becker cannon for tests.
