The S-19 had two 150hp Sunbeam engines in tandem and a cockpit in the nose of each of the twin tailbooms that projected slightly forward of the lower wings. The design seems to have emanated from the Russian War Department, which ordered the RBVZ to match German experiments with twin-boom combat aircraft. The prototype was completed in late 1916.
