After reading the piece on a German night fighter ace in the latest FlyPast I was wondering if any of you had comparable loss ratios for the day and night bombing campaigns?
In other words, did night bombing give Bomber Command crews greater protection than U.S. daylight bomber crews?

I have heard that is just for the military, the British merchant navy had the worst losses.
Interesting Melvyn – they certainly had a hard time of it.
JB … the data you want re. the USAAF sorties/losses etc. is available here
http://www.usaaf.net/digest/operations.htm
But it needs analysing! I can’t do that right now, if you have the time and energy to do so, over to you … otherwise reply here or pm me and I’ll do it some day.
It is an interesting issue but comparing apples with apples (the lies, damn lies and statistics issue) would take some time. For example, the very high level aggregates suggest the circumstances were more-or-less line-ball
[quote the United States Strategic Bombing Survey of Sep 30, 1945 re European Theatre of operations]
In the attack by Allied air power, almost 2,700,000 tons of bombs were dropped, more than 1,440,000 bomber sorties and 2,680,000 fighter sorties were flown. The number of combat planes reached a peak of some 28,000 and at the maximum 1,300,000 men were in combat commands. The number of men lost in air action was 79,265 Americans and 79,281 British. (Note: All RAF statistics are preliminary or tentative.) More than 18,000 American and 22,000 British planes were lost or damaged beyond repair. [unquote]
But remember this is aggregate – all commands, fighters and bombers, etc., etc. The data can be broken down and analysed.
I suspect that when you/me/someone get/s down into the data, it will be found that being in RAF Bomber Command was more risky than a similar stint in the USAAF.

There’s also this quote from the website I’ve linked below … don’t know who it is (re. accuracy etc.) but seems to have a lot of apparently good data.
By the end of the war, RAF Bomber Command had flown 372,650 sorties and lost 8,617 aircraft and 47,268 aircrew, the highest pro rata loss rate of any Allied military unit [unquote]
I think I’ve read somewhere that the fatality rate in RAF Bomber Command was second only to the German U-boat arm (somewhere around 80% fatalities) – but I can’t back that allegation up just now.

I don’t have the data you’re looking for (you need to access Martin Middlebrook’s Bomber Command War Diaries and Roger Freeman’s similar tome on the “Mighty Eighth”) but bear in mind when you do there’s a bit more to it than straight aircraft losses. There’s also fatality rates.
The US approach to aircraft design (exemplified in the B17) was to build heavily armoured heavily defended aircraft. The UK went for hard hitting in its bomber design. So if you compare Lancaster and B17 as the prime examples, you see 2 aircraft of similar proportions, one (B17) with armour, self sealing tanks and 12x .50cal defensive weapons = bomb load c.4,000lbs. The Lanc, only armour the pilots seatback, 8x .303cal defensive weapons = 14,000lb bombload (up to 22,000 using “specials”). Far heavier hitting, but much more vulnerable. Reflect on the effect of 800x Lancs vs 300x B17s hitting a city though!
Knocking B17s down took time and many hits with heavy cannon fire (flak and lucky hits excepted). The aircraft could often fly reasonably well damaged for a period and bail-out rates/capability was therefore good. I believe average crew survival rate of a downed B17 was around 50%.
The Lanc could be and was often taken out by 2-3 cannon hits (one was enough) into the wing tanks (AP between the engines from underneath). The resulting fire destroyed the aircraft’s ability to fly within 30-60 seconds. Exiting was extremely difficult o/a crew location vis-a-vis exit doors/hatches, internal features like the infamous main spar, and the usual short duration of level flight. Fatality rate was very high, in most cases all crew were killed, in a few cases 1 or 2 got out. Contrary to popular misconception, the least likely to survive was the pilot. The stories you read of all but one surviving etc., or heavily damaged aircraft returning were the exception.
So once you’ve got the aircraft loss data, run a 50% survival rate across the US data and say 10% and 20% survival rates across the UK data. It’ll be interesting to see what you come up with.
cheers, Gnome
edit 1 … made the point above re the Lancaster Specials, which were modified to accommodate up to the 22,000 Grand Slam bomb. Normal bomload varied with distance (more/less fuel being carried) and was 14,000lbs maximum at modest (Western Eaurope) range.
edit 2 … note the other UK heavies Halifax and Stirling were less fatal if shot down .. ie you were more likely to be able to bail out. But Stirlings and early model Halifaxes operated at lower altitudes and aircraft loss rates were higher.
