The RAF and USAF's bombing offensive against Nazi Germany was one of the most extended, Allied campaigns of WW2. Fifty-five thousand RAF aircrew lost their lives; this includes four thousand Australian aircrew serving in Bomber Command. The USAF conducted its own air campaign against Germany and lost twenty-six thousand aircrew who were serving with the Eighth Air Force.

Summary

This article from the Imperial War Museum makes the following points about the Royal Air Force's (RAF) Bomber Command in WW2:
  • Created in 1936.
  • Light and heavy bomber squadrons.
  • Relatively ineffective at the start.
  • Received a high proportion of Britain's economic and technological resources and many of its brightest and best young men.
  • Around 55,000 aircrew were killed.
Timeline
1939 
  • 23 operational bomber squadrons.
  • 280 aircraft.
  • Daylight raids against warships and airfields.
  • Heavy losses.
  • Night raids dropped propaganda leaflets.
  • The belief that bombers could defend themselves in daylight if they flew in close formation proved wrong.
1940 
1941  
  • Growing strength.
  • Navigation over blacked-out Europe was still a major problem. 
  • Battle of the Atlantic diverts resources to attacking German warships and U-boats. 
  • German night-fighters and anti-aircraft guns were more effective.
  • Heavy aircrew losses cause a slump in morale. 
  • The Short Stirling—the RAF's four-engine bomber enters service. 
  • Low ceiling so vulnerable to anti-aircraft fire.
1942 
1943 
  • Elite Pathfinder Force guides bombers using coloured marker flares.
  • Major attacks against Germany's industrial heart- the Ruhr.
  • The arrival of the US Eighth Air Force enables a 'round clock' offensive.
  • The RAF operated at night, and the USAAF operated during the day.
1944 
  • Allied bombers caused much devastation in Germany.
  • Took a lot of pressure of the Russian Front.
  • American escort fighters decimate the Luftwaffe, allowing daylight raids to resume.
  • German fuel supplies were successfully targeted.
  • Before D-Day, Bombers attacked coastal defences and hit railways and German troops.
  • Allied bombers made it very difficult for Germany to rush reinforcements to try to counter the D-Day landings.
  • City attacks continue. 
1945 
  • The RAF has 1,500 aircraft.
  • Oil and communications attacks continue to destroy German resources that could have otherwise been deployed against the allied and Russian advances.
  • Controversially, locations so far untouched were razed as they rose to the top of the target list.
