Dragondog,
I don't have the source for the study it was an AAF study conducted after the war I picked up the info from a book by Stanaway.
So, let it pass but with a sidebar comment that any such reference would be Very hard to find.
Doolittle wanted a single fighter for several reasons
1. Planing the various aircraft had different flight envelopes that affected mission planning.
2. inventory it was a nightmare to supply 3 totally unrelated aircraft.
3. The P-38 was in demand everywhere for its unique capabilities.
4. The P-51 was available in the numbers he needed and could do the job - the P-51 was almost tailor made for the war over Germany.
Doolittle didn't care - he wanted the job accomplished deep into Germany and Poland and Czechslovakia. The P-38 couldn't quite get there and besides it was heavily vested in the 15th AF which was to be a co-partner under Spaatz to attack germany from West and South. When he (Doolittle) took over there were precisely One P-51FG (9th AF 354th) and Two P-38 FG's - both operational with the third in England training for early March. All the P-51s were coming to 9th AF. In other words a.) the 8th didn't have any P-51s abd b.) none were sceduled for the 8th AF. period.
The dates I gave for the 55th and the 20th were according to the history of war web site apparently those were the dates they were set up in England.
I believe that but you said 1944 when they (55th and 20th) were in operation in mid October (10/15/43) and late December (12-28-43) 1943 - not 1944
My point with the problems with the P-51 were just to halite the fact that the P-38 had no more issues that any other fighter in the ETO.
Remember, the first combat operations for the P-38(E) was July 1942 in the Aleutians. It had 16months of operations under its belt before the first P-51B-1 packard merlin equipped Mustang rotated off the runway for its first combat mission. This a/c was a major redesign from the B with respect to forward airframe and systems. Compare the first six months of P-51B ops with P-38E, F, G, H and J, then compare the transition from P-51B to P-51D and see if you still believe that?
The P-38s in the 55th went operational in the ETO in October I believe right after the second Schwinefurt raid. the 20th sometimes had aircraft flying with the 55th on missions. At that time October/November 1943 the average loss rate of bombers was 9/10% of the total bomber stream 3/4% (The 8th was not losing 3-4% to flak - everof the bomber shot down were by AAA. By the middle of November with the 55th escorting the overall loss rate had dropped to 4/5%, this loss rate was never bettered.
Two points.
The 8th stood down as far as flying past Bremen/Kiel until mid January, 1944 - and really didn't go aggressively after deep targets until Big Week. Second point, Yes the 8th did get below 4% most of the time after May 12, 1944 and drove it continuously below 2% (mostly flak) for the rest of the War - notably without Lightnings flying escort in ETO.
One thing to be remembered was that the P-51 outfits were also more experienced with combat as most were operational with other aircraft before they received their Mustangs.
True - and False. Brand new (combat) groups flying Mustangs as a unit for their first combat experiences included 354th, 363rd, 357th, 339th - all between December 1943 and April 30, 1944. By the time the 355th converted the 55th, 20th and 363th FG were flying escort missions deep into Germany.
The combat experienced groups included 4th (Feb 25), 355th (March 8), 352nd (April) - all P-47 Radial engine experience that literally did on the job training in the Mustang - all in combat within 7 days of receiving the Mustang and switching over.
As we both mentioned identifiablity was a major issue with the P-38, Donald Caldwell while researching his book JG-27 interviewed many German pilots about how they felt about the various fighters on the P-38 their comments were that they could choose when or if they wanted to attack. P-51s and P-47s were similar enough that the German aircraft often were committed before they realized the other planes were ours. The miss identification allowed for more kills.
I made tha point earlier a a major detraction for the P-38.... easy to spot and 'choose'
Where did you find the date for the release of the fighters from close escort? I've looked for it for a long time.
USAAF Combat Chronicles for one, but the references are legion regarding Doolittle's directive to pursue in the air and on the ground. It was calculated strategy to support Operation Pointblank - destroy the LW before D-Day.. It is a misnomer to use 'release'. The verbiage was 'absent enemy activity, you may dispatch units to strafe'. The Fighter Group commanders that encouraged wholesale abandonment of their escorted bombers didn't remain in command for very long.
As for dives in the P-38 from above 20,000ft the pilot could dive but he MUST close the throttles, go to a flat pitch on the props and if needed roll the plane back and forth - unfortunately few pilots had the experience or will to do this.
The primary issue is that at altitude there was little difference between max level/full throttle speed and in a pitch over - an immediate acceleration to .67 and onset cmpressibility/shock wave. After that it didn't matter, you were piching down, control locked and praying for denser air to gently pull out.
P-38s made up more than half the long range fighters in the ETO until late April 1944 so the P-38 still had a large part of the winning of aerial superiority over Germany.
That would be absolutely incorrect. On February 25, the day the 4th FG flew its first operational mission in the P-51, the entire ETO - both 8th and 9th - had precisely 4 Mustang and two Lightning and 11 P-47 groups. On March 4, 1944 the 38/51's were three to four groups apiece. On March 8, it was five P-51 and three P-38.
The P-38, between January 1, 1944 and May 30, 1944 destroyed 135 air, P-47 destroyed 764 air and the P-51 destroyed 1171 air - mostly Feb 20-may 30.
One other thing neither the 55th or the 20th did much better with the P-51 in fact one group actually did worse!
That is incorrect (20th (88/121), 55th (103/200), 364th (27/226), 479th (52/102) - first number P-38, second number P-51'
In Warren Bodies book P-38 Doolittle comments that the P-38 was "on the balance the P-38 was ahead of all but 1 or 2 of the most outstanding fighters of the war. It was certainly the most versatile. Which is one reason he phased out the P-38s.
His opinion. In the context of enemy aircraft destroyed, just considering the US it was third behind the P-51 (5900+), F6F (5100+) P-38 (3700+) P-47 (3600+)Mossie proponents would have a good argument for most versatile - but P-38 more versatile than P-51 (at 2x cost and 2x maintenance). You could argue that 2 P-51s carry more payload, one could fly escort for the other, one could fly recon while the other CAS - but the P-38 can only do one at a time.
Yes a second factory should have been set up in 1942 at the latest which would have also allowed the P-38K to be produced which was a very capable fighter. A second factory would also have allowed dive flaps approved for production in April to be installed on H and J model P-38's.
