The Messerschmitt Bf 109 were begun to use from 1940 in missions
of fighters-bomber, carrying a bomb of 250 kg., while other variants
as the Bf 109E-5 and E-6 were used as recognition fighters without
cannons. The model Bf 109E-7 was a development of E-4/N, being
able to take an engine for to be thrown instead of a bomb.
Other models were the Bf
109E-7/Trop, the Bf 109E-7/U2, with bigger armour for missions
of assault air -land; or the Bf 109E-7Z provided with major power
thanks to a system of push based on nitrous oxide. A new model
was the Bf 109E-8, developed from 109E-7, equipped with an engine
DB 610E of 1.350 CV; or the Bf 109E-9, recognition fighters developed
from E-8, capably of carrying cameras and without cannons in the
wings. Stopped making at the beginning of 1942 of its version
Bf 109E, practically all the variables were taking two or three
cannons of 20 mm, with great capacity of fire and scope.
Its bigger lack was the limited
radius of action, which was not revealed as a serious problem
until the Battle of England. Thought as a weapon of support to
the rapid advances of the Werhmacht during the Blitzkrieg, it
was made necessary change airport several times, or even to improvise
runways on fields of grass, which was provoking a few accidents.
In the Battle of England, they met an enemy of its level, Spitfire
Mk I.
The German fighter was a
little faster, was carrying cannons and could realize fall down
that the English could not execute, however this one was any more
manoeuvre. In spite of it, a disadvantage was revealed like decisive:
its scarce autonomy come down to 80 minutes, was turning out to
be fatal in combat against the English fighters, which besides
were flying on its own air space, what was allowing fill up quickly.
Going out from the French airports, after crossing the English
Channel only it were having of 20 minutes to fight, for what many
fighters sank in the sea on not having been able to return to
its bases. Besides, its scarce radius of action was limiting its
assaults to the southern zone of the British Isles. The principal
mission entrusted Me 109, was to escort to the average bombardiers
He 111, Do 17 and Ju 88, which were turning out to be very vulnerable
without its support. Such a defensive mission turned out to be
a strategic mistake, since they were forced to not separate of
the bombardiers, which was reducing capacity of action against
the English Spitfire.
