To answer at least one of the questions that has floated through this thread, I've pulled together some data on
F4F and A6M losses from 1 May 1942 through the Battle of Midway. I have not included USN vs IJN encounters
prior to 7 May 1942 as the USN F4F pilots did not encounter the A6M until the Battle of the Coral Sea where VF-42's
Walt Haas was the first USN fighter pilot to shoot down an A6M.
F4F Combat Losses 7 May 1942 through 4 June 1942:
(Format is Ship -- Squadron -- Date -- Number -- Cause)
CV-2 -- VF-2 -- 5/7/1942 -- 1 -- MIA Coral Sea Night Action/Operations
CV-5 -- VF-42 -- 5/7/1942 -- 2 -- MIA Coral Sea Night Action/Operations
CV-2 -- VF-2 -- 5/8/1942 -- 3 -- MIA Coral Sea probably shot down by A6M2s
CV-2 -- VF-2 -- 5/8/1942 -- 2 -- shot down by A6M2 US strike CAP
CV-5 -- VF-42 -- 5/8/1942 -- 1 -- forced down, battle damage by A6M2, US force CAP
CV-5 -- VF-3 -- 6/4/1942 -- 3 -- shot down by A6M2 US force CAP
CV-5 -- VF-3 -- 6/4/1942 -- 1 -- shot down by A6M2 US strike CAP
CV-5 -- VF-3 -- 6/4/1942 -- 1 -- forced down, battle damage by A6M2, US force CAP
CV-8 -- VF-8 -- 6/4/1942 -- 1 -- shot down by A6M2 (possible assist from friendly AA fire), US force CAP
So, we can see that there were a total of 15 F4Fs lost in combat. Of the first three, MIA in Coral Sea night action/
operations, we know that the one VF-2 loss, Lieut(jg) Paul Baker, and one of the VF-42 losses, Ens John Baker,
(these gents were not related, but their identical last names may have contributed to their loss, a short but sad
story of communications problems) were tragically just pilots who were lost in the dark and could not find their
ways back to their ships. The other VF-42 loss, Ens Leslie Knox, simply was never heard from again and no
specific cause can be pinned to his loss, although one of the last survivors of VF-42 still with us tells me that they
all suspected that the cause of his loss was vertigo, not enemy action. Thus, we are left with 12 F4Fs actually
shot down or forced down from damage by A6Ms. In the same period, there were 24 F4Fs lost operationally.
10 of these were the VF-8 strike CAP at Midway, all of which ditched from fuel exhaustion; seven pilots, I believe,
were recovered.
Japanese A6M losses in the same period were;
(Format is Ship -- Date -- Number -- Cause)
Shoho -- 5/7/1942 -- 1 -- shot down F4F strike CAP (VF-42)
Shokaku -- 5/8/1942 -- 2 -- shot down F4F force CAP (VF-42)
Akagi -- 6/4/1942 -- 3 -- shot down, various strike aircraft (non VF)
Akagi -- 6/4/1942 -- 1 -- AA fire Midway Island
Hiryu -- 6/4/1942 -- 3 -- shot down F4F force CAP (VF-3)
Hiryu -- 6/4/1942 -- 3 -- shot down SBD strike force
Hiryu -- 6/4/1942 -- 2 -- shot down, various strike aircraft (non VF)
Hiryu -- 6/4/1942 -- 1 -- forced down, battle damage SBD
Hiryu -- 6/4/1942 -- 1 -- forced down, battle damage SBD
Hiryu -- 6/4/1942 -- 1 -- shot down F4F force CAP (VF-3)
Hiryu -- 6/4/1942 -- 1 -- shot down F4F force CAP (VF-6)
Kaga -- 6/4/1942 -- 5 -- shot down F4F strike CAP (VF-3)
Kaga -- 6/4/1942 -- 1 -- shot down F4F (VMF 221 - land-based)
Soryu -- 6/4/1942 -- 3 -- shot down, various strike aircraft (non VF)
So, we see 28 A6Ms lost in combat. Fourteen, half, were shot down by F4Fs; one by AA fire; five either shot down
out-right by SBDs or lost due to battle damage from same; and eight were lost to defensive fires from various
other strike aircraft at Midway (TBD, SB2U, TBF, B-26). In the same time period there were 21 operational losses,
all from fuel exhaustion; seven were at Coral Sea, the balance at Midway.
Bottom line here is that between 7 May 1942 and 4 June 1942, and, thus, just on the basis of exposure, in the first
six months of the Pacific War, there were 12 F4Fs shot down by A6Ms and 14 A6Ms shot down by F4Fs, or an F4F
victory to loss ratio of 1.167 to 1.
I think, though, we need to be careful with some of the numbers ascribed to the F4F. There is a big, big boost to the
ratio of Wildcat claims to losses that stems from the F4Fs direct follow-on, the FM-2. The performance of the FM-2
was such that the USN considered its combat results separately from those of the F4F. There is, however, a
tendency to lump the two together as "Wildcat Results". This tends to skew the statistics and can lead to,
perhaps, some erroneous conclusions. Further, I would point out that, as with the BuAer bean counters, amongst
the practitioners, those who flew both the F4F and the FM-2, the two were also considered to be different breeds of
cat (pun intended) that simply had a similar appearance.
In it's brief time in combat, the FM-2 posted some pretty serious numbers. Perusing the US Naval Aviation
Combat Statistics – World War II (1946), if you look at the period 1 January 1944 through 15 August 1945,
operating FM-2 squadrons in aerial combat against the Japanese resulted in 422 credits of all aircraft types to 13
losses. During these 20 months FM-2 squadrons flew some 751 aerial combat sorties (combat sorties defined
as flights where aircraft of a given element - division or section - engaged in combat with enemy forces). This
works out to 3.29 sorties for every Japanese VF shot down and 3.87 sorties for every Japanese VT/VB or
overall 1.78 sorties for every Japanese aircraft credited. The FM-2 aerial combat losses work out to 57.8 aerial
combat sorties for every FM-2 lost. Losses to AA fire for FM-2s in the same period were 62 for some 5533
sorties with Japanese AA present, or 89 sorties encountering Japanese AA for every AA loss.
Comparatively in the same period, F6F squadrons flew 6397 aerial combat sorties with 1.3 aerial combat
sorties per credit and 27 aerial combat sorties per loss. F6F losses to AA fire were 527 in the course of some
38,427 combat sorties in the same period where Japanese AA was present, or 73 sorties for every AA loss.
For F4U squadrons there were 1.7 aerial combat sorties per credit and 26 aerial combat sorties per loss for around
2495 combat sorties. AA losses for F4Us were 331 for 24,058 combat sorties facing AA fire, as with the F6F,
some 79 sorties encountering Japanese AA for every AA loss.
From 1 January 1945 to the Japanese surrender, operating FM-2 squadrons were credited with 187 victories
(94 VF and 93 VT/VB) to 1, (yes, he said "one") aerial combat loss. Remember, of course, that a high number
of these credits were scored against some rather single minded adversaries who really weren't paying
much attention to the niceties of aerial combat, focusing primarily on just getting through the CAP defenses to work
their mischief on whatever ship to which they could get the closest. Combat sorties per credit were 1.9 and
combat sorties per losses were 362.
And finally, if you look at just the last year of the Pacific war, from 1 September 1944 to 15 August 1945, FM-2s
in action in aerial combat against Japanese VF only, the results were, credits to losses:
FM-2 vs A6M series - 87 to 2
FM-2 vs Ki-43 - 38 to 3
FM-2 vs Ki-61 - 29 to none
FM-2 vs Ki-44 - 17 to 2
FM-2 vs J2M 1 to none
FM-2 vs Ki-27 - 1 to none
FM-2 vs unidentified S/E VF types - 10 to none
This totals out to 183 Japanese VF types credited for 7 losses (26.1 to 1).
Interestingly enough, another quick calculation from these results tell us that since FM-2 pilots were credited with
94 Japanese VF victories from 1 Jan 1945 to the end of the war and 183 Japanese VF victories from 1 Sept 1944
to the end of the war, the period of 1 Sept 1944 through 31 Dec 1944 was prolific indeed with 89 VF credits over a
four month period, though theses were not without a cost. With 6 FM-2 losses, the credit to loss ratio in the same
four months drops to a paltry 14.8 to 1.
Other results for the 1 September 1944 though 15 August 1945 period were:
FM-2 vs D3A - 88 to none
FM-2 vs D4Y - 5 to none
FM-2 vs B5N - 4 to none
FM-2 vs B6N - 7 to none
FM-2 vs Ki-51 - 1 to none
FM-2 vs Total VB-VT - 105 to none
FM-2 vs E13 - 7 to none
FM-2 vs Total F/P - 7 to none
FM-2 vs G4M - 2 to none
FM-2 vs Ki-46 - 1 to none
FM-2 vs P1Y - 18 to none
FM-2 vs J1N - 9 to none
FM-2 vs Ki-45 - 4 to none
FM-2 vs Ki-21 - 16 to none
FM-2 vs Ki-48 - 21 to 1
FM-2 vs G3M - 1 to none
FM-2 vs U/I 2/E Combat Types - 9 to none
FM-2 vs Total 2/E Combat Types - 81 to 1
FM-2 vs Transports - 1 to none
FM-2 vs unidentified 2/E - none to 1
Total FM-2 vs Non-S/E VF Types - 194 to 1
Total for all FM victories, 1 September 1944 through 15 August 1945 is 377 to 9 or a ratio of 41.9 to 1.

7.0 to 1 (1333 to 191).
