D.F.W. R.II

At least six D.F.W. R.II Riesenflugzeug giant bombers were ordered, with serial numbers R.15/15 through R.20/15. R.15 first flew in August 1917 but spent several months in testing and adjustment. In April 1918 it started operational missions out of aerodromes near Cologne. R.16 made its first flight in May 1918 and joined R.15 during the summer. Little is known of the other planes in the series except that R.20 was cancelled.
