Design and development

Unsuccessfully trying to choose the most appropriate seaplane pilot training command naval aviation factory Rogožarski addressed the 1937th and ordered the seaplane school project that would fit in their characteristics the school board SIM-X. Since she could not make a simple modification (adaptation of existing aircraft SIM-X) for installation of EDO floats, head designer Eng. Sima Milutinovic incorporated increased engine power Walter Major 6 190KS, leading to an increase in aircraft size. Thus, a training school-engine high-flying boat with two float represented an entirely new plane, called SIM-XII-H. During 1937. The access to the project and at the end of the prototype was ready for testing . The test flight was conducted seventh February 1938th test pilot Ivan Koroša in hydro-based Divulje. After the flight tests achieved satisfactory results, ordered the first batch of four copies of these aircraft, which were delivered in mid-1939th year .

Aircraft SIM-XII-H, supported parasol crates, two seaplane float, with engine power Walter Major 6 (190KS), predominantly wooden construction, the fuselage of elliptical cross-section is entirely made of wood and covered with plywood wings are supporting structure made of wood covered with screen, with rounded ends. On each side, the wings are supported by a pair of inclined struts which relied on the fuselage. The fuel tank was located in the central part between the wings that is. at their junction. The first series of aircraft was built two (couple) EDO float (EDO Float Model 47).

Operational history

Experience with the use of aircraft SIM-XII-H, among pilots and technical staff of the aircraft was popularly called a "small SIM", were very positive and the Command PV (Maritime Royal Navy) 15 July 1940th year under contract with the factory for the second series Rogožarski these aircraft (also 4 copies) with the difference that these flying boat was equipped for instrument that is. "blind" flying. Rogožarski this aircraft is delivered in five months but no floats because the floats delivery from Canada was delayed several months. By agreement with the Navy in the factory Rogožarski approached the design and development of domestic aircraft floats for this but this job not completed by the April outbreak of war. In this pre-war two aircraft SIM-XII-H had accidents and two in the Bay of Kotor 1940th year. Both aircraft have been proposed for disposal, and PV is the command that requested the approval of floats from this move to new aircraft (planes SIM-XII-H of the second series) considering that these planes were equipped with Instrument ("blind") flight. Since the approval arrived it was done so that the two aircraft from the second series capable of use before the war broke out .
