The Marinens Flyvebaatfabrikk M.F.2 was a two-seat military biplane floatplane produced by Marinens Flyvebaatfabrikk in 1915 and 1916. It was designed by naval captain Halfdan Gyth Dehli, based on former models by French designer Maurice Farman and improvements by Einar Sem-Jacobsen of the Norwegian Army Air Service's aircraft factory Kjeller Flyfabrikk.[1] BackgroundThe M.F.2 was the second type of aircraft manufactured by Marinens Flyvebaatfabrikk, and was financed by the extraordinary appropriations to the Norwegian Armed Forces after the outbreak of the First World War.[1] ProductionTwo examples of the M.F.2 were delivered from the Marinens Flyvebaatfabrikk in the summer of 1916, with the numerals F.10 and F.12. A third example, F.10 (II), was delivered in March 1918, replacing the original F.10, which had crashed at Karljohansvern naval base on 21 April 1917 after a total of 22 hours flying time.[1][2] ServiceThe M.F.2s were employed for neutrality protection patrols, in addition to being used for student pilots taking their certificates. The M.F.2s were based at the Royal Norwegian Navy's main naval base at Karljohansvern in Horten until July 1918, when F.10 (II) and F.12 were redeployed to the newly established naval station at Kristiansand.[3] The M.F.2s were part of the First Aerial Group prior to the move to Kristiansand.[4] At Kristiansand the two M.F.2s served together with three Sopwith Baby seaplane fighters, and were housed in two aircraft sheds.[5] The M.F.2 type served with the Royal Norwegian Navy Air Service until 2 October 1924, when F.12 was written off after 95 hours and 30 minutes of flying time. F.10 (II) had been wrecked during take off from Kristiansand naval air station on 22 July 1919.[2] The engine of the M.F.2 was a 150 hp Sunbeam V8. The aircraft was equipped with a radio transmitter. It was armed with a fixed Madsen machine gun and could carry a bomb load of 2 x 50 kg, in the form of two small bombs or mines.[6][1] The M.F.2 was the first aircraft operated by the Royal Norwegian Navy Air Service that had permanent armament, or could carry a bomb load. The preceding Rumpler Etrich Taube, Maurice Farman MF.7 and Marinens Flyvebaatfabrikk M.F.1 types had only been able to carry carbines and pistols.[7] The wings of the M.F.2 were shorter than those of the M.F.1, and the tail section of the M.F.2 was completely different from its predecessor and included a new type of altitude and side rudder.[1] Specifications{{aircraft specifications|jet or prop?=prop |plane or copter?=plane |include 'armament' field?=yes |include 'capacity' field?=no |switch order of units?=no |ref=Marinens Flygevåpen 1912–1944.[2] |crew=Two |capacity= |length main=9.73 m |length alt=31 ft 11 in |span main=15.6 metres |span alt=51 ft 2 in |height main=3.59 metres |height alt=11 ft 9¼ in |area main= |area alt= |empty weight main=1,050 kg |empty weight alt=2,310 lb |loaded weight main=1,390 kg |loaded weight alt=3,058 lb |useful load main= |useful load alt= |max takeoff weight main= |max takeoff weight alt= |engine (prop)=Sunbeam 150hp |type of prop= |number of props=1 |power main=150–160 hp |power alt=112–119 kW |max speed main=110 km/h |max speed alt=59 knots, 68 mph |cruise speed main=100 km/h |cruise speed alt=54 knots, 62 mph |range main=350 km |range alt=189 nmi, 217 mi |ceiling main= |ceiling alt= |climb rate main=1.2 m/s |climb rate alt=233 ft/m |loading main= |loading alt= |thrust/weight= |power/mass main= |power/mass alt= |armament=
