The Henschel-produced Hs 123 aircraft became the last operational biplane adopted by the German Luftwaffe heading into World War 2 (1939-1945). Born from a 1933 German requirement for a dive-bomber, several Henschel Hs 123 test aircraft would fly by 1935 (two would be lost to dive accidents in the process). Five such aircraft were then "tested" by the Condor Legion of Germany during the Spanish Civil War (1936-1939) which produced refinements in the design. the biplane aircraft would eventually see combat during the German invasions of Poland, Belgium, France, and the Soviet Union under the banner of the Luftwaffe.
Like many of the single-seat military aircraft appearing in the early-to-middle part of the 1930s, the Henschel Hs 123 showcased some of the traditional design characteristics of World War 1 aircraft - fixed undercarriage, biplane wing arrangement, open-air cockpit. The series was initially fielded through the pre-production Hs 123A-0 designation and these were used by the Luftwaffe to evaluate the design. Initial production models became the Hs 123A-1 and these arrived with 2 x forward-fixed 7.92mm machine guns while being driven by a BMW 132Dc radial piston engine. The dive bomber also was given provision for an under-fuselage external fuel tank or conventional drop bomb and four additional hardpoints were had to each wing element (two per wing).
Performance-wise, the aircraft could manage a top speed of 211 miles per hour and range out to 533 miles with the drop tank installed. Its service ceiling reached 29,530 feet and rate-of-climb was 2,950 feet per minute.
The success of the Hs 123 with the Condor Legion in Spain eventually offered up some minor modifications to the base design. The proposed Hs 123B mark was canceled in favor of the developing Junkers Ju 87 "Stuka" dive-bomber detailed elsewhere on this site. With the Hs 123 making its appearance in 1936, the impressive Stuka followed in 1937 and snuffed out any remaining future the Hs 123 may have had in Luftwaffe service.
Additional combat actions were had by the Chinese who purchased a stock of twelve biplanes and used these against Japanese naval targets during the Second Sino-Japanese War.
