I just looked up the Allied Order of Battle for
July 1943 and it's a bit more fighters than I had originally guessed. This might be helpful to understanding the Mediterranean Theater in general so I thought I'd post it. This is from Shores MAW pp 153-157
I'm just showing US fighter, fighter-recon, or fighter bomber units here though these were all mixed US / RAF. Each US Fighter Group had 3 squadrons of 16 fighters plus an HQ unit of 2-4 aircraft except where otherwise stated (one of the P-39 groups only had one squadron for some reason). Nominal US squadron strength was 16 aircraft though they would typically have about 20 or 25 in various states of repair, with ~8-16 active at any one time. So nominal strength of a FG was about 50 fighters active.
North African Tactical Air Force*
Desert Air Force -216 fighters
57th Fighter Group - P-40
79th Fighter Group - P-40
33rd Fighter Group - P-40
324th Fighter Group - P-40
99th Fighter Squadron (Tuskgegee) - P-40
US 12th Air Support command -170 fighters
31st Fighter Group - Spitfire
27th Fighter Bomber Group - A-36
86th Fighter Bomber Group - A-36
111th Tactical Recon Squadron - P-51A
1437 Flight - A-36
North African Strategic Air Force
5th Bomb Wing - (three groups of B-17s) -100 fighters
1st Fighter Group - P-38
14th Fighter Group - P-38
47th Bomb Wing (two groups of B-25s) -50 fighters
82nd Fighter Group - P-38
2686th Bomb Wing (three groups of B-26s) - 50 fighters
325th Fighter Group - P-40
North African Coastal Air Force
81st FG / 92nd Fighter Squadron - P-39 - 16 fighters
350th Fighter Group - P-39 - 50 fighters
US 1st Defense wing - 100 Fighters
52nd Fighter Group - Spitfire
81st Fighter Group - P-39
North African Photographic Reconnaissance Wing
US 3rd Photo Recon Group -32 fighters
5th Squadron - F-4 (Lightning)
12th Squadron - F-5 (Lightning)
In addition to this Shores left out the
US Night Fighter Squadrons, which also performed day-time coastal patrols and maritime strikes near Algeria and Tunisia, Malta, Sardinia, Corsica and Italy. These included three squadrons, all equipped with the Beaufighter while in the MTO:
414th Night Fighter Squadron - Beaufighter - 16 fighters
415th Night Fighter Squadron - Beaufighter - 16 fighters
416th Night Fighter Squadron - Beaufighter - 16 fighters
So by my count (correct me if I'm wrong my arithmetic isn't stellar) that ads up to 832 US Fighters active in the MTO at that time in official strength, which means probably at least 1,000 counting replacements, aircraft under repair etc. Of that number, in my opinion, ~130 losses to accidents or mechanical failure on or near base in two months doesn't seem necessarily beyond the ballpark of reality, though that is only a guess. Hopefully the TO&E is useful or interesting in it's own right.
Breakdown by type, by my count - is
P-40s - 266
Spitfires - 100
P-38s - 182 (counting recon)
P-51s - 120 (counting A-36 and recon)
P-39s - 116
Beaufighters - 48
*North African Tactical Air Force / Desert Air Force is also where most of the RAF Spitfire units were.
EDIT: Here is the Commonwealth breakdown for anyone interested.
DAF Commonwealth Fighter Units included:
40 SAAF sqn - Spitfire
60 SAAF sqn - Mosquito
6 sqn -Hurricane
7 SAAF Wing ( 3 x squadrons) -Kittyhawk
239 Wing ( 5 x squadrons) - Kittyhawk
244 Wing (5 x squadrons) - Spitfire
322 Wing (5 squadrons) - Spitfire
324 Wing (5 x squadrons) - Spitfire
225 Sqn - Spitfire
241 Sqn - Hurricane
There were also 6 x Spitfire squadrons, 3 x Beaufighter squadrons and a Mosquito squadron based on
Malta.
Coastal Air Force RAF units included
77 Sqn - Spitfire
255 Sqn - Beaufighter
GC 2/3 (Free French) - P-40
GC 2/7 (Free French) - Spitfire
Plus "
HQ Air Defense Eastern Mediterranean" which included 4 Groups consisting of 21 squadrons of mixed Hurricanes, Beaufighters and Spitfires, plus two flights of Gladiators! I think this was a reserve?
From what I understand RAF squadrons were usually 12 fighters nominally with 6-10 probably being more typical of available strength for an active unit.
