Arado Ar 196

The Arado Ar 196 is a shipboard reconnaissance low-wing monoplane aircraft designed and produced by the German aircraft manufacturer Arado. It was the standard observation floatplane of the Kriegsmarine (German Navy) throughout the Second World War, and was the only German seaplane to serve throughout the conflict.

The Ar 196 was designed in response to the Kriegsmarine's requirement to replace the Heinkel He 60 biplane after the intended successor, the He 114, had proved to be unsatisfactory. Arado submitted a monoplane design to the Reichsluftfahrtministerium (German Air Ministry, RLM) while all competing bids were for biplanes; the RLM decided to order four prototypes of the Ar 196 in late 1936. Testing of these prototypes during late 1937 revealed their favourable performance characteristics, leading to production being authorised and formal service tests commencing in the opening weeks of 1939. Starting in November 1939, production switched to the heavier land-based Ar 196 A-2 model; it would be followed by several more models until production of the type was terminated during August 1944.

All capital ships of the Kriegsmarine were equipped with Ar 196s. The aircraft was commonly used by numerous coastal squadrons, and as such continued to perform reconnaissance missions and submarine hunts into late 1944 across the Mediterranean, Aegean, and Black Seas. Perhaps their most noteworthy engagement was the involvement of two Ar 196s in the detection and capture of HMS Seal. In addition to Germany, the Ar 196 was exported to the Bulgarian Air Force. Numerous examples were captured by the Allies, some of which were operated as late as 1955. Several Ar 196s have survived through to the twenty-first century, preserved for static display; none are known to be in an airworthy condition.

In 1933, the Kriegsmarine looked for a standardized shipboard observation floatplane. After a brief selection period, the Reichsluftfahrtministerium (German Air Ministry, RLM) decided on the Heinkel He 60 biplane. This was one of a line of developments of a basic biplane airframe that appeared as a number of floatplanes, trainers, and fighters. Deliveries started in a matter of months.

By early 1935, it was determined that the He 60's performance was lacking, thus the RLM requested that Heinkel design a replacement aircraft, resulting in the He 114. The first prototype was powered by the Daimler-Benz DB 600 inline engine, but it was clear that supplies of this engine would be limited and the production versions turned to the BMW 132 radial engine instead. However, the aircraft proved to have only slightly better performance than the He 60 while its sea-handling was deemed to be poor and it did not meet strength requirements for catapult launches. Rushed modifications resulted in a series of nine prototypes in an attempt to solve some of the problems, but they did not help much. The Navy gave up, and the planes were eventually sold off to Romania, Spain and Sweden.

During October 1936, the RLM issued a request for a He 114 replacement; the corresponding specification stipulated that the aircraft would use the BMW 132, and requested prototypes in both twin-float and single-float configurations. Responses were received from Dornier, Gotha, Arado and Focke-Wulf. Heinkel declined to tender, contending that the He 114 could still be made to work. With the exception of the Arado low-wing monoplane design, all submissions received were conventional biplanes. The Ar 196 was a semi-cantilever low-wing aircraft. The design of its fuselage was reminiscent of the Arado Ar 95 maritime patrol biplane. The wings and forward fuselage were metal skinned, while a fabric covering was used for the empennage and rear fuselage. Hydronalium, an alloy known for its resistance to corrosion in maritime environments, was extensively used throughout the aircraft The interior space of the floats was used to house fuel.

Deeming Arado's submission to be the most modern and capable aircraft, the RLM placed an initial order for four prototypes. These prototypes included a seaplane configured for catapult launches and stressed to perform diving bombing attacks. The RLM was conservative by nature, thus they also ordered two of the Focke-Wulf Fw 62 designs as a backup measure. It quickly became clear that the Arado was performing effectively, while also being easier to manufacture, as such, only four prototypes of the Fw 62 were built.[citation needed]

On 1 June 1937, the first prototype, Ar 196 V1, performed its maiden flight from the Plauer See. Once its use in the flight test programme had been completed, Arado begun rebuilding V1 with the intention of attempting to set a new air speed record in its category; alterations included the installation of a more powerful BMW 132SA radial engine, a new low-profile canopy, and various aerodynamic refinements to the airframe. However, the RLM learnt of the intention and forbade Arado from proceeding on the grounds of maintaining military secrecy.
