During the Battle of Britain, the Luftwaffe employed three types of level bombers and one type of dive bomber.
The dive bomber was the Junkers Ju 87 Stuka. It was primarily designed for troops support and it was devastatingly successful in this role during the Battle of France. But during the Battle of Britain, the Stuka suffered heavy losses due to its slow speed and it being vulnerable to fighter interception after diving on its target. The Stuka had limited payload and range and when its losses increased they were removed from operations over England.
The Luftwaffe had three bomber types it used for medium and high altitude level bombing, they were the Heinkel He 111, the Dornier Do 17 and the Junkers Ju 88.
Of these the He 111 was used in the greatest numbers and was the slowest. The Ju 88 was the newest and the fastest once it had dropped its mainly external bomb load. The Do 17 had the smallest bomb load.
All three level bomber types suffered heavy losses from British fighters but the Ju 88 disproportionately so.
Germany's newest bomber
The Junkers Ju 88 was developed in the late 1930s as a "fast-bomber" - a concept based on the fact that the Ju 88 would be supposedly so fast that fighters couldn't intercept it.
When the prototype Ju 88 V1 first flew, it achieved 360 mph. Georing (head of the Luftwaffe) was very impressed. Its streamlined fuselage was modelled on the Do 17 but with fewer defensive guns because of the belief that it could out-run late 1930s fighters.
Sadly by the time Luftwaffe planners like Ernst Udet had "improved" it with features added (including modifying it for heavy dive-bombing), the Ju 88's top speed had dropped to 280 mph.
The A-1 series prototypes were given Jumo 211B-1 or G powerplants and was the favoured variant by Georing for mass production. He was promised 300 Ju 88s a month.
Production was delayed terribly by developmental problems, causing service introduction to be over a year late. Only 12 Ju 88s were in service by the time Germany invaded Poland.
Even then, production was dreadfully slow with only one Ju 88 manufactured a week as problems continued.
How bad were the Ju 88 losses over Britain?
By August 1940 Ju 88 A-1s and A-5s were reaching operational units just as the Battle of Britain was intensifying.
Sadly for the Luftwaffe, the Ju 88s higher speed did not prevent its losses exceeding those of the Do 17 and the He 111.
Ju 88 losses over Britain between July and October 1940 amounted to 303 aircraft.
Do 17 losses over Britain between July and October 1940 amounted to 132 aircraft.
He 111 losses over Britain between July and October 1940 amounted to 252 aircraft.
Why did the Junkers Ju 88 suffer so many losses?
A considerable number of the Ju 88 losses were down to the aircraft's difficult behaviour compared with the proven He 111, and the crews' lack of experience on the type. Many crews had only converted to the Ju 88 only shortly before.
Of the 39 losses recorded for July 1940, only 20 were due to enemy action. The others were due to training accidents, crashes or malfunctions over mainland Europe.
A series of field modifications were implemented to make the Ju 88 less vulnerable, including replacing the single MG 15 rear machine gun with a twin-barrelled MG 81Z machine gun and fitting additional cockpit armour.
Arrival of the Flagship Ju 88 A-4
The Ju 88 A-4 went into service only during the closing days of the Battle of Britain. Although the A-4 was even slower than the A-1, it had ironed out nearly all of the problems of the A-1. The A-4 brought in additional improvements including more powerful engines.
It was the arrival of the A-4 that signalled the maturing of the Ju 88 into one of the most versatile combat aircraft of the Second World War. It was eventually used successfully as a bomber, dive bomber, night fighter, torpedo bomber, reconnaissance aircraft, heavy fighter and even as a flying bomb in the closing stages of the War.

Evening! Ju88A-4 might have featured right at the end of The Blitz, but it was definitely not around in 1940. Ju88 armament on the A-1 and A-5 (which was in service before the A-4... the A-5 entered service towards the end of the daylight BoB) was still mostly the MG15. There might have been few field mods to add MGFF in the lower nose) MG81Z wasn't introduced until 1942.
