Bf-109 E4

[Danelov]

The E-7 were builded from August 1940 and production ended en october of the same year. Some 439 of this model were builded. The first unit to have the model was the I./LG 2 in August 1940 at Jever. From Aug 22, the unit was deployed at Calais Marck and returned to Germany Nov 5, 1940. One visible difference in this model was the propeller spinner carenage, closing and obturing the inused engine cannon hole. Some extra kph gained with this modification. Was retrofitted also to some olds Es.

In fact a lot of Emils later became E-7 when they got upgraded to the same standard. The Emil is somwehat unique in the german designation system as it was the only type that received a new subseries number when upgraded. Because of that production numbers don't tell you how many E-7 (or E-4 for that matter) really were in use.

The planning progressed in the same manner with the G series. Continuous innovations, a new type mark was published aggregating these then. For example, the late G-6 and early G-14 the same type. G-14/AS and early G-10 have minor differences too. It occurred that later types received previous type components because of production or supply difficulties. In the later section of the war this increasingly more considerable.
