The Arado Ar 196 was a shipboard reconnaissance low-wing monoplane aircraft built by the German firm of Arado starting in 1936. The next year it was selected as the winner of a design contest and became the standard aircraft of the Kriegsmarine (German Navy) throughout World War II. In October 1936, the RLM asked for a He 114 replacement. The only stipulations were that it would use the BMW 132, and requested prototypes in both twin-float and single-float configurations. Designs 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 were conventional biplanes. This gave the Arado better performance than any of the others, and the RLM ordered four prototypes. The RLM was conservative by nature, so they also ordered two of the Focke-Wulf Fw 62 designs as a backup. It quickly became clear that the Arado would work effectively, and only four prototypes of the Fw 62 were built. The Ar 196 prototypes were all delivered in summer 1937, V1 (which flew in May) and V2 with twin floats as A models, and V3 and V4 on a single float as B models. Both versions demonstrated excellent water handling and there seemed to be little to decide, one over the other. Since there was a possibility of the smaller outrigger floats on the B models "digging in", the twin-float A model was ordered into production. A single additional prototype, V5, was produced in November 1938 to test final changes. Ten A-0s were delivered in November and December 1938, with a single 7.92 mm (.312 in) MG 15 machine gun at the rear seat for defence. Five similarly equipped B-0s were also delivered to land-based squadrons. This was followed by 20 A-1 production models starting in June 1939, enough to equip the surface fleet.
