Quote: " Why would the LW need that range when it had airfields everywhere?"
For ex for attacks against Allied convoys in Med. If there were Allied fighters around unescorted LW bombers tended to suffer losses. LW reply was to try to attack at dusk but when on 26 Nov 43 fighters had loitered around later than usually, they shot down 6 out of 20 attacking He 177s, surely LW would have had use for an effective escort fighter. Saying nothing when they needed to attck North Africa ports, especially after May 43.

I have a copy of Gooderson's book, so what? Maybe you don't understand that it was much easier for pilots to hit tanks in open spaces of Ukraine than in more closed country. When German tanks were caught in fairly open area as the 112 PzBrig was at Dompaire, fighter bombers could be rather effective against tanks, as all participants of the combat at Dompaire testified. On the other hand during the big battles on Summer 44 in Karelian Isthmus appr 400 Il-2s didn't succeed to destroy even one Finnish AFV and according to Soviet info but contrary to LW claims and Finnish opinion during these battles the ability of Ju 87s of I./SG 3 or Fw 190s of 1./SG 5 to destroy Soviet AFVs was very limited. The terrain is rather closed there.
Hello Tante Ju
the Finnish experience was that in practice the max flight time of Bf 109G without a drop tank was 1,5 hours and with a 300l drop tank over 2h. Combat sorties were usually 1h long. Reason for that was that at most economic speed sparking plugs began to collect carbon and exhaust gases "flooded" into cockpit. Finns definitely thought that Bf 109G was a rather short range fighter. If Bf 109F's/G's range was so good why LW didn't utilize that in Med but allowed their unescorted bombers took losses and then, because of that, switched to more inaccurate night attacks in Med and in the East, for ex during 43 attacks on Soviet a/c industry. n fact LW really had a need for long range escort fighter, as least a fighter that would have been capable to escort He 111s as far as they could deliver useful bomb loads.
On Hispano, 4 Hispanos was more than enough against even biggest LW bombers, He177 or Do 217, so RAF had no reason to go to bigger guns. That was shown many times.
I agree with LW armament from 109G-5 onwards, MG 151/20 was a very good gun, personally I liked the armament of 190D-9, 2xMG 131s and 2xMg 151/20s well concentrated.
On P-51 , its armament was clearly enough against fighters, its combat history proves that. And it was perfectly capable to dispatch He 111s or Ju 88s.
On fighter-bombers, in fact pilots of FB units had trained for their trade and according to Finnish tests, even pure good fighter pilots learned very fast to drop their bombs accurately. Il-2 was an another solution to CAS problem, it had its pros and cons, it was more vulnerable to enemy fighters but less vulnerable to AAA and totally invulnerable to rifle calibre weapons.
You might take a little time to think why German offensive in Ardennes in Dec 44 was timed for a long period of bad weather. That would have been illogical if Allied CAS was so ineffective that you and Ctrian seemed to think.

The 'Tatics' the Germans had in the early part of WW2 was 'blitzkreig' as far as I understand it. The aircraft were all designed around that concept.
There was no Lancaster or Flying Fortress.
The only long range weapon that the Germans planned was the U boat.
Range of FW 190A, BF 109G was sufficient for this task.
No, it is not. I am trying to evaluate the design of the aircraft. I do not rate the Mustang as being better than the Spitfire because it carried carried six .50s and a lot of ammunition. It was better in this regard because it could carry the weight at the performance levels it did achieve. That the USAAF chose to use this weight for a 2nd class gun installation isn't the point. The airframe designer/manufacturer rarely gets to choose the weapons the airplane will be equipped with.
Trend here is that both countries used the same engine, which had been designed from the start for an engine mounted cannon. Showing commendable foresight in the days when standard armament was a pair of 7.7-8mm mgs. However it was also a 800hp engine in it's early days and simply couldn't power an a plane with more than one cannon and a pair of small mgs. Neither could anybody else at the time. Early gun was not the Hs 404 but a slower firing, less powerful, lighter gun.
I am not saying you are doing it, but I really dislike the morphing 109 with it's 3 guns/5guns. I have gotten into debates before and the 109 proponent wants to argue the fire power of the 5 gun version but wants to argue the performance of the 3 gun version. Pick one and stick with it.
Heavier armament did decrease the maneuverability in the Spitfire. But since the Spitfire A.) was designed to have a heavier weapons load to begin with (around 165kg for the eight .303s) and B.) had that big wing adding the same amount of weight increase degrades performance less.
Typhoon was planned from the start for 4 cannon. problems with the guns forced the twelve .303 version. No 'decrease' in maneuverability. While a 109 a 7,000lbs is 61.4% of the typhoons 11,400lb weight the 109 also has 63% of the wing area. While wing loading is certainly not the only factor in maneuverability I think it shows that the 109 was getting too small to carry the loads asked of it.
Soviet considered 109G world class. Very fast, very good climber, 5 pointer Messer heavy hitter too. You forgot 5 pointer - and all 109G can be five pointer.Soviets were also saddled with the VK-105 engine, 85% of the power of the DB 605A. Their part wood construction was also heavier than all metal. 'Standard' factory finish often meant 20-30kph less speed than trial figures. 109 would certainly look world class.
Soviet aircraft were as good as best of Western aircraft. Old cold war myth they were not.. only thing not as good as radio. In many ways, Soviet planes more advanced. Look at Yak 3. La 7. Better than Western counterparts. More manouverable, faster. Armament least as good.
Also five pointer 109G - speed 650 km/h. World class. One of few fastest at time.
I did not forget the '5 pointer'. One of the original Pro 109 poster's in this last flurry of posts was running down the Mike Williams site for using the performance figures of the '5 pointer' in his comparisons. Fine and dandy, you want to argue the flight performance of the '3 pointer' you don't get to use the armament performance of the '5 pointer' and vice versa.
OK. Make analysis. With 5 pointer. I am to know if thesis of yours is correct - did small airframe with heavy guns was worser fighter automatically? Because that is what you say. Say 5 pointer comparison with similiar heavy armed aircraft. FW 190. Typhoon. Four cannon Spitfire, four cannon Allison Mustang. Climb, speed, turn, range - same timeframe. We shall see if thesis is true.. or Jakovlev or Messerschmitt school was right.
Great, we are comparing theoretical ferry ranges? 200mph at 16,500ft is a nice speed for moving a plane from one point to another. It is also almost a guaranteed way to get dead flying in a combat area. You are aware that a Spitfire MK V can do 225mph at 10,000ft burning 29 gallons an hour or 263mph at 20,000ft burning 36 gallons an hour? not quite what the 109F can do but slap even a 90 gallon tank under it and see what you get.
Data Me 109F clear. Biggest range - achieved at 7 km (23 000 ft), at 410 km/h (254 mph). Consumption: 130 liter per hour. (28 gallons). Conclusion easy to draw.
http://www.beim-zeugmeister.de/zeugmeister/index.php?id=22&L=0/
I see what I get, easy... Spitfire has 85 gallon tank. Slaps on 90 gallon drop tank. Uses that, switch to 85 gallon, fights, remainas perhaps 70 gallon, tries to return, what happens 20 gallons short of base...?
90 gallon no practical unless internal tankage is greater.
If the 109 isn't short ranged then neither is the Spitfire. Under realistic conditions, say 340-350mph at 20,000ft or so, and making allowances for combat 2 -2.5 gallons a minute and neither one is going that far.
Spitfire was short ranged. Mid/late war Marks. First Mark was medium range.
109 was short ranged in 109E. Medium range in later model: F, G, K.
Facts show. Look up.
The Spitfire had room for more tankage. the 109 not so much.
I do not agree. Similiar sized aircraft. No technical reason why 109 cannot have more tankage. But no need. Current range already good as best Spitfire, Mark VIII. With 2/3s fuel.. This is reason why spitfire added fuel. Unaccaptable range otherwise. Reason: exactly big wing... too much drag.
And I really like the logic. Compared to other fighters the later 109s were short ranged, but since they didn't need long range for the few types of mission they were still doing we shouldn't use range as a factor in seeing if they were still world class?
Because it wasn't done does not mean impossible. Faulty logic. Did 109 need range of Mustang? No. Faulty logic again. 109 could stay German airspace longer than Mustang and B-17 already. Task: interceptor. This is shooting down enemy in own air space. You do not build aircraft you do not need.
I am not arguing about which gun was better, guns changed over the life of many of the planes. The planes with a larger amount of weight and volume devoted to armament could be upgraded easier. The gun that was supposed fire through the prop on the 109 changed at least 4 times. the original 20mm design was a bust and they had to try to substitute a 3rd MG 17 as a stop gap. The 20mm MG/ff was also intended (2nd try) but never worked well enough for combat. The Germans finally get a working motor/cannon with the MG/151 in either caliber. The change to the MK 108 was better in some ways, not so good in others. The 109 had the weight allowance and volume for the motor cannon. After that everything was sort of a bodge.
109G carried 223 kg weapons and munition. 109K: 259 kg. With gondola: 458/494 kg. K-6: 522 kg.
Russian planes powered by V-12s had the same problem as the 109 with some factors worse and others better. The engine was low on power and never really got better, this means a small plane to get performance. Wooden construction of some types meant high structure weights and low volume in some interior spaces. Russians sacrificed gun life to make light, fast firing, high performance guns. The lighter guns and low ammo loads were necessary for performance but the Russians were not happy with the 3gun fighters unless it was 3 20mm guns.
Yes. But considering example of Soviet fighter firepower at much ligher weapons load, it just shows that achievement of set firepower do not depends on just adding more "gun weight".
We have been over that but try this. A DB 605 burns 10.68 litres a minute while using MW-50, say they use it for just 5 minutes. 54 litres. the engine burns 8.03 litres at 'normal' take off power, say this power is used for 10 minutes (USAAF planners called for 15-20minutes) another 80 litres. 266 liters left if the plane was carrying a drop tank and dropped it at at the instant the engine went to full MW50 power or full take off power when at altitude.
The engine burns 6.43 litres at the short power setting (30 min?) The engine in the "F-4" was good for 1.66litres a minute at that low cruise setting but that speed is useless if there is a chance of enemy planes about. Some old books claim a range of 350 miles at 330mph at 5,800 meters. no drop tank. This may very well be wrong but an endurance of just over an hour with no combat allowance does limit German options. Like fighters based in Wiesbaden-Frankfort can't reach a bomber stream routing through Bremen and return without drop tanks, or landing near Bremen after combat.
Not really. As the USAAF found out, and just like the Luftwaffe found out. it is not enough to plod along beside the bombers. To be an effective escort the fighters ( at least some of them) have to fly higher than the bombers to keep them from being bounced from above and they have to fly faster than the bombers (weaving back and forth over the bomber flight line) so they have some speed in hand when the interceptors are spotted. Trying to accelerate to combat speed from most economical cruising speed takes too long. and surrenders too much initiative to the enemy. This means the fighters actual "escort radius" was always a smaller fraction of it's book range than the bombers "mission radius" compared to book range. The other limit on fighter escort radius was that the radius was determined not by total fuel carried but the fuel left in the internal tanks after the drop tanks had been dropped and the fighter had engaged in a number of minutes of fuel sucking combat flying. Having 75-60% of internal fuel left would not be uncommon and flight out of the combat area cannot be done at most economical settings either unless you are trying to help the enemy run up his scores.
The Do 17 has already been mentioned. The Heinkel 111's wing while shorter in span was 12% bigger in sq. ft. than a Wellington. He 111s usually had more power until the MK III's came along. With a single hand aimed mg out the nose, top and bottom (3 total) this hardly sounds like a ground strafer, attack plane. Even the old "E" version (stepped windscreen) could carry 2200lbs of bombs for a 900 mile range. Sounds like a lot of range for a 'tactical' bomber.
He wasn't daft was he. If I was at home I'd dig out the actual figures for armoured vehicles destroyed by allied fighter bombers during the Normandy campaign. That's specifically armoured vehicles. It is very low indeed. Maybe someone else has them to hand.

OK. Make serious analyse. Set condition - equal to all. Plane has to fly this speed for this long. Then fly at this speed for this long. Then fly to maximum rating for this long.
Use same standard. Then apply to 109, P-47, Spitfire, Mustang, FW 190 etc - you choose. And see what you get.
Hello Ctrian
artillery was also decisive at eastern front, especially Soviet artillery, IMHO Germans thought so and definitely Finns had higher regard on Soviet artillery than on Il-2s. Also Soviets, at least in Baltic area, thought German artillery effective, but after all Heer's defensive doctrine was based on artillery fire.
