The Albatros B.II, (post-war company designation L.2) was an unarmed two-seat reconnaissance biplane designed and produced by the German aircraft manufacturer Albatros Flugzeugwerke. It was the aircraft that brought Albatros Flugzeugwerke to the world's attention.[citation needed]

The B.II was active during the first half of the First World War, initially being used to perform aerial reconnaissance, and later as a primary trainer.[1]

Design and development

There is some dispute over the origins of this B.II; the aeronautical engineer Ernst Heinkel claimed to have designed the aircraft, however this claim is widely considered untrue by many aviation historians.[2] It is commonly accepted that the aircraft's actual designer was Robert Thelen. Irrespective of this controversy, the design process commended during peacetime and drew extensively upon preceding Albatros B.I.[1] In comparison to the B.I, the B.II had a noticeably shorter wingspan than the B.I.

The B.II was operated by a crew of two; as was commonplace at the time, the pilot was seated in the rear cockpit while the observer was seated in the forward position.[1] The field of view from observer's position was partially obstructed downwards by the center-section trestle while the forward view was negatively impacted by the protruding engine block. To improve the downward field of view, large square cutouts were present in the lower wing spars.[1] When Albatros developed the armed C.I based on their B-series, the seat positions were swapped so that the observer/gunner had a better view and clear field of fire.

The fuselage, which was atypically strong for the era, was primarily composed of plywood.[1] The structure comprised four longerons of mixed construction, comprising ash forward of the cockpit and spruce to the aft, that tapered sharply towards the rear. The design of the fuselage was commonplace amongst the company's twin-seat aircraft.[1] The nose of the aircraft features a rounded metal panel along with the aircraft's engine; various engines would be used to power the type, such as the Mercedes D.II, which was capable of up to up to 89 kW (120 hp). The majority of the engine block was uncovered.[1] Cooling was achieved via radiators fitted to the sides of the forward fuselage.[1]

The B.II was furnished with a large triangular tail, akin to the B.I; it had an unbalanced rudder and elevator control surfaces.[1] Both the tailplane and fin were braced via a streamlined steel strut. The structure was mainly composed of lightweight steel tubing, while the exterior covering was fabric.[1]

During 1914, the B.II established a world altitude record of 4,500 m (14,800 ft).[citation needed]

A floatplane variant of the B.II was developed, known as the W.1 or B.II-W, as was a purpose-built trainer with increased wingspan and different engines, designated the B.IIa. Further developments of the design led to the Albatros B.III, which was produced in small numbers.

Operational history

First flying in 1914, large numbers of the B.II were built and, though it was relegated from front-line service in 1915 following the introduction of the armed C-type two-seaters, the B.II remained in service as a trainer until 1918 and was still operated by the Swedish Air Force in 1919 and by the Polish Air Force during the Polish-Soviet war of 1920. A B.II from Feldflieger Abteilung 41 was one of the first landplanes (as opposed to Zeppelin) to drop bombs on England that caused some damage;[3] on 16 April 1915, ten bombs were dropped by hand in the area of Sittingbourne and Faversham. No significant damage or casualties resulted.[4]

Service in Sweden

In 1914, the German manufacturer Albatros-Flugzeugwerke GmbH of Berlin-Johannisthal, was touring several countries in northern Europe, displaying their new aircraft, the Albatros B.IIa. At the time, it was considered one of the best primary trainer aircraft. However, the landing gear and propeller were damaged when it arrived in Sweden. Due to the outbreak of World War I, no spares could be sent, and the aircraft was interned. It was repaired and used as a trainer by the Swedish Air Force. This aircraft was later copied and manufactured in Sweden by six different aircraft companies: Svenska Aeroplanfabriken (SAF), Södertelge Werkstäder (SW), Marinens Flygväsende (MFV), Nordiska Aviatikbolaget (NAB), AB Thulinverken as the Thulin C and Flygkompaniets Verkstäder Malmen (FVM). It was the first military trainer aircraft in Sweden and received the designation Sk 1 and Ö2 in the Swedish Air Force (the two types differed slightly, mainly by choice of engine). An FVM-built Sk 1 Albatros is on public display in the Swedish Air Force Museum near Linköping. The type was used until 1935. One aircraft was later sold to Finland.

Service in Finland

NAB Albatros Type 9 (and SW 20 Albatros), Type 12 and Type 17 were among the first aircraft of the Finnish Air Force. It was in use between 1918 and 1923. There were two Type 9s, and one each of the Type 12 and 17. There was also one SW 20 Albatros, which was similar to the Type 9. The Type 12 aircraft was destroyed in the ferry flight to Finland; the remains of the aircraft were found near Eckerö, Åland. Type 12 was actually a modified Curtiss Twin JN with floats made by NAB.

Austro-Hungarian service

The Albatros B.II was widely used by the K.u.K, but was given the designation Albatros B.I (series 21).
