Even today high quality bearings for specific applications that involve exotic materials operating at high temperatures, like aerospace for example, are difficult to source with short lead times.

The P51 Mustang was a US fighter which first saw action with the RAF. Whilst it was a good plane, the British found it's performance was poor at high altitude and swapped out the original Allison engine with their own Rolls Royce Merlin engine (the same engine used in the Spitfire, Hurricane and Lancaster amongst others). This made a vast improvement to the Mustang's performance enabling it to operate efficiently at higher altitudes. This in itself increased the plane's range as at higher altitudes, where the air is thinner, there's less drag, additionally the smaller Merlin allowed larger internal fuel tanks to be fitted. When the USAAF needed a long range escort fighter the British modified Mustang was the best option available, the addition of external drop tanks meant that the Merlin Mustangs could escort bombers all the way to Berlin and back,

Hi Connor, later in the war RAF accuracy was greatly improved by the pathfinder force, using the best navigators the RAF could find, sticking them in a Mosquito and having them mark the target with flares, then a pathfinder squadron of Lancaster's would drop more flares of different colours that changed every raid, so the Germans couldn't guess the colour and light up a load of flares on a patch of wasteland as a decoy. They may drop incendiaries as well, then the main bomber force would start to arrive. It could involve several hundred Lancasters and Halifaxs, it was called a bomber stream, because the formation was only maybe three planes wide, but it stretched back for miles and miles and miles.

Connor: just watch the video

The Americans stopped painting there planes as they did not last that long and to paint the plane took about 300 lbs of paint.

@@Ayns.L14A For the next important and powerful Merlin 66 engine, Rolls Royce finally decided to use the Bendix-Stromberg Injection carburettor. The American Bendix-Stromberg pressure carburettor was developed in the mid 1930’s and was in production from 1938. This carburettor was designed to operate as a fully pressurised fuel system that dispensed with the problematic float controlled fuel level with its emulsion tubes and diffusers. Negative G had no effect on fuel flow or carburettor function. The pressurised and metered fuel flow was delivered as a spray into the inlet air stream just in front of the supercharger inlet. This feature virtually removed the risk of carburettor icing, in fact the throttles and chokes of the injection carburettor did not need heating by hot oil or coolant circulation at all and their deletion removed several other problems associated with the previous provision of those heating circuits. Rolls Royce had been aware of the Bendix-Stromberg Pressure type of carburettor for several years and versions of the carburettor were used on many American engines including the Allison V-1710. Notably, Packard built their Merlins in the USA with a version of the Bendix PD16 from the very start of Packard Merlin production. ROLLS-ROYCE MERLIN CARBURETTOR DEVELOPMENT page

Ahhh so this is what 'just cause' based that mechanic of

The main difference was the variety of the payloads these planes could carry. The USAF were only able to carry small bonbs and a light payload. The Americans built plans arounb crew safety but in reality were not effective as a bombing force. The RAF could hit a much larger variety of targets with more distruction to those targets.

We did night and the US did day because they couldn't cope with navigating at night. This is what British pilots told you. There were lots about when I was a child-this is what they all said, that American crews were courageous but less accurate. The German parachutists in Crete were definitely shot, but only if you had guns-they were also pitchforked by anyone, including grandmothers. Villages were decimated for this-but they did it for sure. We went to the museum in Heraklion Crete they had photos of this happening , they were only welcoming when they realised we were British- they shielded lots of British soldiers who were stranded when the island fell- oh yes that's cousin Yanni , he's a bit simple etc! The thing that made this effective is that we bombed by day AND night-think of the psychological effect of that. In the end it is the teamwork is what worked- the Germans realised they couldn't win with this level of bombing, that's the meaning of total war.

There was an interesting electronic warfare campaign between the Luftwaffe ground-based and airborne radar and the RAF's jamming & other counter-measures.

Bomb aiming maps had rivers painted silver so they matched more closely the river patterns on the ground which at night reflected as silver in the moon light.

The US bombing was not as accurate as claimed. US bombers dropped bombs on Swiss towns near the German border. The famed Norden bombsight was found to be no more accurate than bombsights used by the Germans or British. Both the Germans & the British tested the Norden bombsight & found it lacking in combat situations. The British used Mosquito fighter/bombers for accurate bombing of specific targets such as an individual Gestapo building or breeching the walls of prisons without hitting the buildings holding prisoners. The British conducted very accurate bombing using the Tallboy & Grand Slam bombs towards the end of the war. My husband's uncle flew with the famous 617 Dambuster squadron that specialised in pinpoint bombing after the dam raid. They were able to hit warships from great heights.

"Not so the Americans, who from first to last were determined to bomb by day and in the end achieved their object with conspicuous success." page 1 Hyperwar Royal Air Force 1939-1945 Vol III

With flak, the early shells were mechanically timed. It would take roughly one second to climb 1000ft. With the bombers at 30,000ft that’s 30 seconds for the shells to arrive if the bomber keeps flying straight and level. At low altitudes AA guns like the German 20mm are used. Those shells explode on impact with the target. The allies later developed the proximity fuse for higher hit probability. Today some vehicles like the CV9040 use gated proximity fuses that activate once close to the target range so they can fly over trees or other obstacles without detonating early

Just about anything that moves in an aircraft or piece of machinery employs bearings. Engines are probably the most important component that relies on bearings. Accurately machined ball bearings are essential to bearing production. Schweinfurt produced a good percentage of ball bearings for the German aircraft industry. Take that one facility out and you severely hamper aero engine and therefore aircraft production, at least for a while.

Stuff About London The American Memorial Chapel, St Paul’s

Before the US entered the war in Europe, the UK mainly practiced night time bombing as it was harder to see the aircraft. The US disagreed with this strategy and did round the clock bombing. Of course the US could do this because it had more planes.

@etherealbolweevil6268

29 күн бұрын

Also, had sat out 1939, 1940 and 1941 and a lot of 1942 so no backlog of personnel losses.

When WW2 started Britain lacked 3 main things - a heavy bomber capable of reaching Germany, accurate bomb sights, and a long range fighter to defend the bombers. Germany had control of the skies over Europe and Britains early attempts at daylight bombing sustained horrendous losses. We reverted to night time bombing as a means to protect our aircraft as much as possible even though bombing accuracy was very poor, carpet bombing an area became the accepted method to increase the possibility of hitting the intended targets. The USA first bombed Germany in January 1943, believing that their bombers were so heavily armed that they were relatively safe. The idea was “A slower, heavily armed plane, able to clear its way with its own armament, can always get the best of a faster pursuit plane…. A unit … of … slower heavily armed planes is in a position to stand up to the fire of enemy pursuit planes and carry out its mission successfully.” This view was shared in the years after World War I by Brig. Gen. William “Billy” Mitchell, regarded by many as the founder of the U.S. Air Force, and by many of the officers who served under him. By the beginning of World War II, many of these officers were now generals in senior command positions. Regardless of the changes in military aviation and especially in fighter technology that had taken place in the 20 years between the two wars, many of these men remained rigidly committed to Mitchell’s views on aerial warfare, and failed to consider the improvements in fighter technology since 1918.. The first major strategic air battle of the war was fought as the USAAF attacked both the Messerschmitt factory at Regensburg and the ball-bearing production center at Schweinfurt. The Germans discovered the B17 had a severe weakness to head on attack and the American losses were devastating; 60 bombers were lost, 36 from the Schweinfurt flight and 24 from the Regensburg flight. In addition, 87 bombers were damaged beyond repair, or were forced to be left behind in North Africa because of inadequate repair facilities. This led to a total loss to the Eighth Air Force of 147 B-17s from that one raid, and the USAAF eventually lost over 8000 bombers over Germany by 1945. After the Schweinfurt-Regensburg raids, there were fewer long-range bomber attacks into Germany as the Eighth Bomber Command licked its wounds and replaced its losses. It did not resume the heavy bombing of Germany until September. Losses continued to mount as 106 bombers were knocked out of the sky during the first 10 days of October. On Thursday, October 14, 1943, the still-unescorted B-17s were again ordered to attack the factories at Schweinfurt. Not surprisingly, the raid was a disaster. The Luftwaffe was ready and attacked the 291 B-17s, 60 were shot down, five crashed on landing while 17 more managed to land but were damaged beyond repair. The total number of B-17s lost was therefore 82 of the 291 dispatched bombers. In addition, 142 that had returned to England were damaged, therefore, a mere 33 of the 291 returned unscathed-just 11 percent of the force. Losses and damages added together totaled to more than 50% for the month, at this rate, an entirely new bomber force would have to be created almost every three months in order to sustain the level of the bomber offensive. The bomber generals’ belief in unescorted daylight precision bombing-a belief to which they had been faithfully dedicated for virtually their entire military careers-was a complete disaster It was a tragic irony that the P51, a long-range escort fighter had been readily available for about two years since 1940. Things improved dramatically when the P51D was introduced in 1944 and could accompany the bombers all the way to their targets, and by late 1944 had more or less achieved aerial supremacy over the Luftwaffe, which in turn made it safer for the bombers during daytime.

No one had heavy bombers at the start (except possibly the Russians). Germany never did get them and the US ones never had a heavy bomb load.

The British bombed at night as their day raids led to high attrition rates. Their accuracy was so bad early in the war that the Germans could never work out what they were trying to hit. Later they became more accurate and could hit cities but not individual targets. This resulted in lots of destroyed houses but it did not hugely effect German production. The British approach was a bit war crimy as bombing cities resulted in civilian deaths. With the Americans they could do more precise bombing. They employed economists to try to work out bottlenecks in the German economy. Thus they tried to knock out ball bearing production and later oil. The main achievement of the Americans was to destroy the German air force through attrition. Towards the end of the war they hit the railway system which achieved some results. The Germans probably did more damage to themselves by diverting huge amounts of resources into the V1 and V2 programs which were a complete waste of time.
