Obsessed that make 30 Obsessions the British have this year an interest in things on planet earth is NOT an Obsession
spitfire first Built 1938
The first prototype BF 109 flew in October 1935—powered by a British Rolls-Royce engine, since even the Jumo was not yet available. The Jumo-powered Bf 109B, armed with four 7.92-mm (0.3-inch) machine guns, entered service in 1937 and was immediately tested in combat in the Spanish Civil War.
the Spitfire was superior to the Messerschmitt Bf 109 fighter in a dogfight since it had considerably better turning ability than its German arch-rival.
RANGECombat ranges were comparable. Both designs were initially designed to defend airbases against enemy bombing, and that was reflected in their range figures on internal fuel—680 km for the Spitfire I A/B and about 660 km for the Bf 109E.
A German Me 109 E is in pursuit of a British Spitfire Mk. I. The Spitfire turns as tightly to the left as possible which is more tightly, than the German Me 109 is able to do. The better climbing and diving qualities of the latter are of no use to the pilot in this situation: the bullets from the two machine guns and the two cannon simply pass harmlessly by the tail of the pursued Spitfire and into empty space.
Following feedback from pilots of the Condor Legion, Messerschmitt also modified the Bf 109 prototypes with a 20 mm cannon mounted between the engine cylinder banks, firing through the propeller hub. However, the vibration from the cannon was so severe that it proved to be unworkable. This problem was resolved much later in the war. In the meantime, several alternatives were trialled. The Bf 109B utilised an engine-mounted machine gun in place of the cannon. This, too, proved to be problematic.
The Bf 109C featured a redesigned wing to accommodate two 7.92 mm machine guns, with ammunition boxes stored in the fuselage. The system worked in tests, but failed under the strain of air combat. The Bf 109D carried four guns – two in the nose and two under the wings. Bf 109E-1s carried the same armament. The E-3 models, though, were equipped with a 20 mm cannon under each wing, installed in two streamlined blisters along with a 60-round ammunition drum. Finally, the issues with the engine-mounted cannon were resolved in the F-4 model, which flew with a 20mm cannon that proved to be very accurate.
When it came to maximum speed at level flight there was little to choose between either model: Spitfire (365 mph, 587 km/h), Me 109 E-1 (354 mph, 570 km/h). The Spitfire was somewhat faster at altitudes above 20,000 feet, it was slower at lower altitudes. The slight difference at level flight was of scarcely any significance, but when climbing—at least at altitudes below 20,000 feet—and diving, an Me 109 pilot would be likely to leave any Supermarine Spitfire struggling in its wake.
Overall the spitfire was better and May 1940 to October 1940 proved that when we won the Battle of Britain
with 2 x 20mm cannons a 4 303" machine guns out manoeuvred the 109 and had about the same fire power except the 108 could not fire its top Guns without blinding the Piloti
as for Quantity, the workhorse was the Hurricane and the Germans needed more because the RAF was shooting faster than the Luftwaffe was shooting down Spitfires
More than 1700 Luftwaffe (German air force) planes were destroyed.
The Royal Air Force (RAF) lost 1250 aircraft, including 1017 fighters
Eventually, 14,000 Hurricanes would be built and 22,000 Spitfires (including Royal Navy Seafires). that is 36,000 fighters against Germanys 35,000
Loosing about 700 more than the RAF from May to October 1940 saved the UK from Invasion that was only 5 months the Luftwaffe never recovered then attacked the USSR
only an Idiot would do that
