Sablatnig SF 1
   Only a single example of this two-seat seaplane was built, and it was accepted by the Navy in October 1917. Engine, 160 h.p. Mercedes D III. Span, 191 m. (62 ft. 8 1/8 in.). Height, 4.35 m. (14 ft. 3 1/4 in.). Weights: Empty, 1,015 kg. (2,233 lb.). Loaded, 1,650 kg. (3,630 lb.). Speed, 125 km.hr. (78.125 m.p.h.). Climb, 1,000 m. (3,280 ft.) in 10 min. Armament, none.

Sablatnig SF 2
   The Sablatnig SF 2 was a conventional wood and fabric seaplane used for reconnaissance and coastal patrol. A radio transmitter was carried, but no armament. Some twenty-six aircraft were delivered from August 1916 onwards, and were allocated Navy Numbers 580-585, 609-618, 705-714. Nos. 791-800 were built by L.V.G. (Koslin) and were probably SF 2s. Engine, 160 h.p. Mercedes D III. Span, 18.53 m. (60 ft. 9 5/8 in.). Length, 9.525 m. (31 ft. 3 in.). Height, 4.25 m. (13 ft. 11 1/4 in.). Area, 56 sq.m. (605 sq.ft.). Weights: Empty, 1,078 kg.

Data applies to aircraft 609, each batch often differing slightly from each other.

Sablatnig SF 5
   A development of the earlier SF 2, the SF 5 was a conventional reconnaissance seaplane. Radio transmitter only was carried, and no armament. Altogether 101 aircraft of this type were delivered from March 1917 onwards, and it was only lack of sufficient data that prevented the type being dealt with in the main text. Navy Numbers allotted: 791-800 (L.F.G. built), 968-987, 1017-1036 (L.V.G. built), 1214-1223 (L.V.G. built), 1224-1233, 1352-1371, 1459-1468 (L.F.G. built), 1514. Engine, 150 h.p. Benz Bz III. Span, 17.3 m. (56 ft. 9 1/8 in.). Length, 9.6 m . (31 ft. 6 in.). Height, 3.55 m. (11 ft. 7 3/4 in.). Area, 50.5 sq.m. (545 sq.ft.). Weights: Empty, 1,052 kg. (2,314 lb.). Loaded, 1,605 kg.

Sablatnig SF1

  The Sablatnig SF1 was designed as an unarmed, two-seat reconnaissance floatplane of conventional design and wire-braced, fabric-covered wood construction typical of the time. Powered by a 160 hp Mercedes D.III engine, only one airframe, Marine #490, was built. Delivered to the SVK (SVK - Seeflugzeug-Versuchskommando) on 26 August
1915, tests were satisfactory and it was transferred to Borkum in November. The SF1 flew several operational patrols from Borkum in December.
  On February 3, 1916, the SF1 failed to return from a patrol and no trace of the floatplane was found. Production orders for a modified SF1, the SF2, followed.

Sablatnig SF2

  The SF2 was derived from the earlier SF1 by enlarging the vertical tail surfaces for improved directional stability and modifying the wing bracing by deleting a diagonal strut on each side. Like the SF1, the SF2 was an unarmed, two-seat reconnaissance floatplane; however, a radio transmitter was carried, making it a naval category BFT. Powered by the 160 hp Mercedes D.III as was the SF1, the SF2 was slightly lighter and faster than the SF1.
  The SF2 was put into production for the German navy and 36 were produced in the following batches and Marine Numbers:
  First production batch: Marine Nr: 580-585 (6 aircraft)
  Second production batch: Marine Nr: 609-618 (10 aircraft)
  Third production batch: Marine Nr: 705-714 (10 aircraft)
  Fourth production batch: Marine Nr: 791-800 (LVG built) (10 aircraft)
  The first production SF2 floatplanes were delivered between June and September 1916. The SF2 was used both for operational reconnaissance missions and training.

Sablatnig SF5

  Based on the modest success of the earlier SF2, the SF5 was developed to replace it in production.
  Like the SF2, the SF5 was an unarmed two-seat reconnaissance floatplane with wireless transmitter, naval category BFT. The SF5 was powered by the 150 hp Benz Bz.III instead of the 160 hp Mercedes D.III used in the SF2, probably because fighter aircraft had priority for the preferred Mercedes. The SF5 also had revised wing bracing; an additional pair of struts bracing the outer wingtips of the upper wing replaced the pylon struts over the outboard bay of interplane struts. This gave the SF5 a sleeker appearance and may have reduced drag. The SF5 also had enlarged vertical tail surfaces. The SF5 was somewhat lighter than the SF2; in light of subsequent experience this lighter structure may have compromised its strength. The final production batch had revised wing bracing to address shortcomings in the original design.
  A total of 91 SF5 floatplanes were built in the following series, with minor differences between them. The LVG machines omitted the wireless transmitter for their role as trainers. The first two LVG series were delivered from summer 1917 through the end of the year.
  Marine Nr: 968-987 [20 airplanes]
  Marine Nr: 1017-1036 (LVG) [20 airplanes]
  Marine Nr: 1214-1223 (LVG) [10 airplanes]
  Marine Nr: 1224-1233, [10 airplanes]
  Marine Nr: 1352-1371 [20 airplanes]
  Marine Nr: 1459-1468 (LVG) [10 airplanes]
  Marine Nr: 1514 [1 airplane]
  The first production batch by Sablatnig was delivered between January and May 1917. The SF5 was not popular with its crews, who had probably expected an improvement over the earlier SF2 but were disappointed. The SF5 had poor speed and climb rate; moreover, it was not especially stable. Some crews asserted that its rated cruising speed of 110 km/h (68 mph) was instead its maximum speed, and "Lame Crow" was reportedly its nickname amongst the crewmen who flew it.

Sablatnig SF6 / B.I

  The SF6 land plane, a derivative of the SF5 intended for training, is included here for continuity of the SF series and because it is not in the N-type book. Also known as the Sablatnig B.I, it was powered by the same 150 hp Benz Bz.III as the SF5. As far as is known, only one aircraft was built.

M.Dusing German Aviation Industry in WWI. Volume 2 (A Centennial Perspective on Great War Airplanes 85)

Sablatnig-Flugzeugbau-Gesellschaft m.b.H., Berlin (Sab)

Foundation:

  Josef Sablatnig initially studied mechanical engineering at the Technical University in Graz and electrical engineering at the Technical University in Brno. When the technophile Sablatnig heard about the successful flights of the Wright brothers, he left Europe and went to the USA for some time to study with the Wrights. Before returning to Germany in 1910, Sablatnig bought a Wright airplane that same year. In 1911, he became a naturalized Prussian citizen. In the same year he took up employment with Louis Bleriot and then in Wiener Neustadt with the Autoplan company, where Sablatnig met the Munich engineer Karl Bomhard.
  In May of the same year, Bomhard applied for a patent on a biplane with sweep and V-shape. He was also involved in the development of a monoplane called "Monobiplan". However, he lacked any flying experience. In 1911/12, he had a biplane built at Goetze-Flugzeugwerke. A second biplane was commissioned from Lohner, which was based on the proven model of the Lohner-Pfeil biplane. This Lohner-Bomhard biplane achieved remarkable feats in 1912 - an altitude of 850 meters.
  1912 was also the year in which Bomhard returned to Germany and met Josef Sablatnig. The latter further developed the "Bomhard arrow biplane", which was built by the Berlin coachbuilding company Kuhlstein.
  Sablatnig was a founding member of Union-Flugzeugwerke in 1913, where the first Bomhard biplanes were also mass-produced.
  During the First World War, he was involved in building up the naval air force as a war volunteer in Kiel. On October 5, 1915, Dr. Josef Sablatnig and the banker Josef Mollinger founded their own aircraft design company, the "Sablatnig-Flugzeugbau GmbH", which, among other things, designed and built the types Sablatnig SF 2, SF 5 and SF 6 in small series from 1916 onwards in the premises acquired from the Goetze Flugzeugwerke. Since the small company was overwhelmed by production orders, it was supported in this by Luftfahrzeug-Gesellschaft mbH (LFG, Roland).
  The military abbreviation was "Sab".

Aircraft Development:

  During World War I, as a war volunteer under Prince Heinrich of Prussia in Kiel, he was involved in building up the German naval air force. The first naval aircraft designed by Sablatnig, SF 1, registration 490, was built in Berlin in the workshop of the boat builder Rethel. The necessary steel parts were supplied by the Gotze company. Sablatnig presented this aircraft to the Navy administration in the summer of 1915 and hoped for a positive evaluation, since the performances presented certainly gave cause for acceptance of this aircraft as a new naval aviator type.
  Sablatnig, without having already opened his own aircraft manufacturing company, received an order to build 16 aircraft, a significant number for the Navy at that time. In the absence of his own workshops, Sablatnig agreed with Dr. Gotze to have the naval reconnaissance planes built under the designation SF 2, in the latter's aircraft works. The aircraft were delivered in the summer of 1916.
  When the Reichs-Marine-Amt held out the prospect of a follow-up order for 30 to 40 aircraft, Dr. Sablatnig and banker Moiling set up Sablatnig-Flugzeugbau-Gesellschaft mbH, Berlin, at the beginning of October 1916 by purchasing Department III of the Gotze Company at Schlesische Str. 26.
  Subsequently, they created the Sablatnig SF 2, SF 5, SF 6, and SF 8 types, which were built in small series. Greater success was achieved with the SF 5, a direct development of the SF 2, of which 101 aircraft were delivered. However, since the small company was overwhelmed by production orders, it was supported by Luftfahrzeug-Gesellschaft mbH (LFG) and Luft-Verkehrs-Gesellschaft (LVG) by acting as licensees. Sablatnig built the FF 49c under license for Flugzeugbau Friedrichshafen.
  In 1917, construction of landplanes began after an SF5 was fitted with a wheeled landing gear instead of floats for experimental purposes and successfully tested.

The front view of the SF1 emphasizes the care taken in minimizing frontal area for minimum drag. Unfortunately, the myriad of bracing wires added significant drag to the airframe, negating much of the advantage of the streamlining.
J.Herris - German Seaplanes of WWI /Centennial Perspective/ (15)
Регистрационный номер: 490 [5]
The rear quarter view of the SF1 emphasizes its streamlined vertical tail surfaces - and the struts bracing it. As a mechanical engineer and pilot Sablatnig understood the need for streamlining but was unable to design a robust structure without excessive drag. In fact, the structural design was inadequate both in strength and aerodynamic cleanliness despite the well-shaped nose, as exemplified in the need for additional bracing struts and wires above the outer interplane struts.

Employed as two seater advanced trainers, 580 was the first of 26 delivered to the German navy between June 1916 and May 1917. The SF 2's power was supplied by a 160hp Mercedes D III, giving the machine a top level speed of 81mph at sea level.

The first SF2, Marine #580, embodies the streamlined nose and rakish profile typical of early Sablatnig seaplanes, showing that Sablatnig understood the need for streamlining to achieve performance. The SF2 also exhibits the profusion of struts and bracing wires typical of Sablatnig seaplanes, revealing how difficult it was to design a sturdy yet low-drag airframe with the materials and design techniques of the time. Despite Sablatnig's advanced technical training, he was unable to advance the structural and aerodynamic state of the art for seaplanes. The result was the SF series had, at best, average performance and mediocre strength and durability.

SF2 Marine #612 (at left) and another SF2 two-seat reconnaissance seaplanes warm their engines before departing on a patrol over the Baltic Sea, late 1916. Like most seaplanes used for this purpose during the first two years of the war, they carried no defensive armament. The observer occupied the front cockpit and the windmill generator for his WIT equipment can be seen at this location. Machines were operated in pairs so that one could assist the other in the event of engine or any trouble that necessitated a forced landing at sea.

Регистрационный номер: 968 [2]
Tiger-striped Marine Number 968 was the first SF5. The SF5 was closely based on the earlier SF2, although minor structural modifications were made to reduce weight. The most obvious change was the revised wing struts; the overhead bracing of the upper wing was replaced by an additional pair of struts attached to the front, outboard interplane strut. The 160 hp Mercedes used in the SF2 was in great demand for fighters, so the SF5 used the 150 hp Benz Bz.III. The Sablatnigs were not as robust as the Friedrichshafens and did not have as good sea-keeping. Nor did they offer the exceptional performance and maneuverability of the Brandenburg W12 and its successors.

SF5 Marine Number 1230, from the fourth production batch, carried the standard late-war naval camouflage. The large radiator suspended from the upper wing created a lot of drag, as did the legion of struts and bracing wires. The additional pair of struts bracing the outer wingtips on the upper wing replaced the pylon struts over the outer bay of interplane struts used on the SF2, giving the SF5 a cleaner appearance. Aircraft of this type were used for maritime reconnaissance in the Baltic and Flanders.

The painting The Seahawks by Steve Anderson illustrates an attack by Sablatnig SF5 Marine #1023 on a Russian steamer on August 29, 1917. On that day Oblt. dRMI Hermann Pohrt and Flgmr.d.R. Johannes Jensen, flying from Angersee, spotted two loaded Russian cargo steamers. They attacked the first steamer, about 1,000 tons, with six bombs from about 700 meters altitude.
