Milo, how many of those captured a/c you listed was airworthy and flight tested, or performed on tactical trials ?
"The 109 was a failure during Bob being unable to protect the LW's bombers adaquately."
By that criteria, all WW2 fighters were failures unless deployed in overwhelming numbers. By that criteria, the Spit and Hurri were failues as well as they could never stop any German bombing raid reaching their targets. Besides the 109s task was to shoot down enemy fighters. It did that very well, far more British fighers being lost to 109s, than vica versa. Some RAF (Hurri) squadrons fled outright when they spot the 109s. Perhaps they had different experience with the 109s in combat. But comparing the role in an escort fighter, I think we should ask those 55 thousend RAF bomber crews what they think of the Spitfires escort fighter capabilities.. why could they operate only during the night for 6 years. I think it all started at Wilhelmshaven, when the 109s were there, but the Spits - nowhere.
"Over the Reich, it was again a failure, unable to stop the USAAF's 8th AF bombers. The Fw190 doing a better job of it. "
Hmm, AFAIK, the FW 190 didn`t stop the USAAF heavies either, for reasons far beyond the tech aspects of the plane. Appearantly the FW 190 was more suited in the bomber destroyer role than fighting off the escorts, the latter was the task of Bf 109s which were seen as superior fighters in that enviroment; the 190s required their protective screen to operate effectively. Luckily for the LW, these two could supplement each other very well.
"One has to land and take off. The 109 could be 'tricky' when landing. "
Every aircraft is tricky on landing. It required more careful attention on landing, yes. No plane is 100% perfect, yet the 109 was operated successfully with even minimal ground service from the frozen airstrips of Norway and Russia to the hot deserts of Africa. On the other hand it was more forgiving in the air than any other fighter, could be quickly and easily serviced, and required only a small runway for takeoff and landing, shorter than the Spitfire or the FW 190, even according to the British.
"During the war the Spitfire`s fuel capacity was increased by about 50%, but range actually descreased slightly.
The 109s fuel capacity remained the same, yet range increased by about 50%."
Proof required.
Hmm, the Spitfire Istarted with a 85 gallon main tank, the XIV ended the war with 120 gallon main tank. The range of the Spit I was something like 480 miles, the range of the XIV was 460 miles.
The 109E, F, G and K all had 400 liter internal tankage. The Emil had 665km (413miles) max range, the 109F had 835km even with a high speed cruise, (520miles), the 109G had 1160km (725miles) on an economic cruise.
All ranges referring to internal tanks only.
So I was wrong because the 109 actually increased it`s range via perfecting the aerodynamics and powerplant by 75%, not by 50%. Most of this difference roots in that the Spit didn`t get an airframe facelift from time to time.
