During the War Bomber Command was eventually to consume 1/3 of British military production and had a budget the size of the whole of the Army’s. The RAF was based upon the principle of bombing and in the 20’s and 30’s Bomber Command dominated Air Force thinking. To the extent that Fighter Command was ill funded and neglected until the late 30’s.
It is a little known fact that during the battle for France and subsequent Battle of Britian that Bomber Commands crews suffered higher losses than Fighter Command as day after day they were sent out in daylight without escort over numerous well defended sites. During the whole war some 55000 men were to die in action and roughly another 15000 in training and other accidents.
When the war began the following were the main aircraft on inventory:
The Fairey Battle
The Battles were the mainstay tactical weapon, underpowered and underarmoured they were to suffer horrendous losses in France and soon withdrawn from the main inventory.
The Bristol Blenheim
Twin engined light bomber, fast enough when first introduced into service but by 1940 outclassed by German fighters. These were also thrown into the fray in France and beyond, only to suffer many losses. An interesting point about this aircraft is that it had a rearward firing MG behind the right engine!
