 Each R.VI bomber cost 557,000 marks and required the support of a 50-man ground crew.The R.VI required a complex 18-wheel undercarriage consisting of twin nosewheels and a quartet of four-wheeled groupings for its main gear to support its weight, and carried two mechanics in flight, seated between the engines in open niches cut in the center of each nacelle.The bombs were carried in an internal bomb bay located under the central fuel tanks, with three racks each capable of holding seven bombs.
