Discussion of Aircraft Kill Claims
This information was emailed to me by Bill Talbott, Major, USMC (Ret)
in response to item #5 on the WW II History bit.
He has given me permission to share it here.
#5 Not that bombers were helpless. A B-17 carried 4 tons of bombs
and 1.5 tons of machine gun ammo. The US 8th Air Force shot down 6,098
fighter planes, 1 for every 12,700 shots fired.
I would like to offer some comments regarding your entry on the
number of Luftwaffe fighters shot down by 8th Air Force bomber crews.
The number cited was most likely "Claims". Most of these were later
changed to confirmed kills by Air Corps intelligence BUT they knew the
numbers were exaggerated by around 400+%. The reason for the
over-claiming (a problem for all Air Forces in the war) were many-some
technical, some political.
Technical
- After some limited experimentation, and inspection of downed
bombers, the Luftwaffe discovered in 1942 that the tactic that would
yield the most success against a US bomber box bristling with M2.50 cal
MG's was a head-on pass. It was simple. Bomber armament was weakest in
the nose position. Additionally, the high closing speed limited the
fighter's exposure to defensive fire (it also made the target solution
difficult with only a 3-6 second window for an accurate burst). The Air
Corps later added chin turrets to their B-17's and nose turrets for
their B-34's and this made the Luftwaffe's fighter jock's job even
hairier.
- Doctrine called for this head on pass to be accompanied by a
climbing turn out of the attack box and a sweeping turn around to the
front for another pass. The reality was that at 25K altitude the ME-109,
and particularly the un-supercharged FW190, was struggling. Often a
climbing turn was out of the question; especially if they bled off any
speed with evasive maneuvers post firing pass. The presence of any
escort fighters made an attempt at a sluggish climbing turn a sure
guarantee to ride the silk down. Thus, the most common attack was a head
pass followed by a half roll and dive out of the attack area. The
tactical goal of the fighter pilot was to damage the bomber and have it
drop out of the box where it be more easily attacked. This half roll,
accompanied by the Daimler-Benz' power plant's cough of black smoke in
this maneuver, made many bomber gunners think the fighter was hit and
spiraling down. Also, literally dozens of gunners were shooting at the
same fighter. If each gunner thought he hit it; each claimed it. Sorting
that out was a monumental task for the Air Intelligence officer.
Political
- The Luftwaffe had the absolutely worst signals intelligence security
of any of the German services. We read their signals easily.
Consequently, we knew as soon as the following day, how effective our
defensive fire was by reading Luftwaffe maintenance availability
reports. These were sent by radio in the Occupied Counties and by
telephone in Germany proper. It is hard to claim we shot down 100
fighters when enemy signals traffic shows only 10 lost and 20
damaged-but that's what we did. Why? Because we wanted the crews to
think they were hurting the people shooting them down. How can you ask
people to take such horrendous casualties and at the same time tell them
"Boys, you're only stinging them." The maintenance of this necessary
deception was essential to the conduct of the campaign. Since then it
has entered into WWII mythology.
- If the kills claimed by the 8th Air Force were even 50% correct, we
would have swept Luftwaffe's homeland defense force from the sky in
1943. Instead, we had to restrict bomber raids to shallow penetration
after Regensburg and Schweinfurt raids so we could make well our losses
and build up an escort fighter force.
- We aren't the only ones that did it. The RAF knew their fighter
pilots over-claimed victories by a factor of at least 2.5 times during
the Battle of Britain. The Luftwaffe records for the same period show a
factor of 2.0 over-claiming. The RAF over-claimed by a factor of 3-4
times actual Luftwaffe losses during the Channel Campaign of 1942 and
again knew it. Luftwaffe technical superiority (introduction of the FW
-190) and superior pilot skill levels (JG-26 in Abbeville, Lille France
were the Luftwaffe's Top Guns so to speak) at that point was telling.
The RAF knew that morale would collapse if the fighter jocks realized
they had lost over a thousand planes and crew for negligible results.
Same as the story for our Bomber crews a year later.
Anyway, I really liked your site. Lots of good information in a very
readable format. Well done!
