Messerschmitt Bf 109G-10/Avia C-10 ‘Vigorous Fighter’

The Messerschmitt Bf 109 was a German fighter aircraft designed in the mid-1930s and it represented the first modern fighter of the era. Originally conceived as an interceptor, later models were developed to fulfil various roles, such as bomber escort, fighter-bomber, day and night fighter, ground-attack or reconnaissance. Various armament modifications evolved in service, using pre-packaged or field kits. The aircraft was of an all-metal monocoque construction, featuring an enclosed canopy and a retractable landing gear.

The G-series aircraft were introduced in mid-1942. The initial variants differed only in minor details from its predecessor, the Bf 109F, most notably in the more powerful engine. Except some early aeroplanes, the bulk of Bf 109G-10s were fitted with DB 605D engines and featured the Erla clear-view canopy, large main wheels with corresponding large oblong wing bulges, deeper oil cooler under the nose and tall tail fin.
The first Bf 109G-10s appeared in service in November 1944 and the following variants were produced: G-10 light fighter (with two MG 131 guns and a single MG 151/20 gun in the nose), G-10/R2 recce fighter, G-10/R6 bad-weather fighter and G-10/U4 fighter (equipped with an engine-mounted MK 108 cannon). In total, about 2,600 aircraft were produced by Erla, Messerschmitt, WNF and Diana factories.

After the war, a small batch of 21 Avia C-10 fighters (later designated the S-99) were completed to serve with the Czechoslovak Air Force and Police Air Force.
