Five prototypes of this new and improved single-seat fighter biplane appeared in 1933, powered by BMW VI or Junkers Jumo 210 engines. The first version to enter production and service (1936) was the Ar.68F, powered by the BMW engine, followed after a small production run by the superior 514kW Jumo Da- or Ea-engined Ar.68E. Prototype Ar.65G and H versions were subsequently built, of which only the supercharged 533.4kW BMW 132 Da-engined 'H' was fully developed. But even this failed to enter production despite having four machine-guns and an enclosed cockpit for the pilot. A few Ar.68 remained operational as night fighters during the first months of World War II and were the Luftwaffe's last operational biplane fighters.

Hate to have to answer my own question, but I came up with some additional information on this aircraft. It seems 511 aircraft of this type were produced during its production run. Eight of these are confirmed prototypes. This leaves 503 to be split up between the E and F versions. In 1939 the Luftwaffe only carried a handful of these aircraft on their roster. Meaning the balance were probably either relegated to training duties or written off in accidents.

Any idea on the production quantities of the "E" and "F" versions?

The choice of engine was influenced by the availability. Rethel wanted the Jumo 210 but other manufacturers had claims before Arado so they had to settle on the BMW VI until supplies of the former were more readily available. The advent of the Bf109 was the writing on the wall for the biplane fighter and thus the Ar68 was the last such type to fly with the Luftwaffe. Just prior to this decision the Ar68H was flown using the BMW 132Da radial, a license built Pratt and Whitney Hornet, this engine offered a very much improved performance (max speed 400 km /h)but it was all too late.
Do you have any comments?
