    On the other hand, outside the European theater, the Merlin was somewhere between an also ran and a minor player in terms of usage. Worldwide, the engines that saw the widest use were the Allison V 1710 and various US radials. Even Commonwealth aircraft made by Canada or Australia, as two examples, ended up using American radial engines rather than British ones.

    The Merlin had nearly zero impact on the Pacific War, SWPA war, Eastern Front, and only a moderate one in the Mediterranean. The US engines were ubiquitous, the Merlin never was.
    Does the above bold statement apply to 1939, 1940, 1941?

      Actually, the Merlin was in the minority in DAF use. None of the bomber force used it. Less than half of fighters assigned used it. The most common fighter in use by the DAF was the P-40. The second most common was the Hurricane.
      Sorry, but so what if the bombers used different engines than the Merlin? Although some Wellingtons may have had them fitted.

      As for P-40 versus Hurricane, arrivals in the Middle East and Malta between January '41 and September '42 were, respectively: 1,131 and 1,924 (plus 467 Spitfires)

      More importantly the Allies would have been SOL if they had to rely on the Allison V-1710 to power their defence against Axis bombers.

        The bold part is incorrect as 462 Squadron RAAF's Halifax bombers were Merlin equipped.

          Pretty much. France, Belgium, Finland, etc., all ordered American aircraft with American engines. The Allison by 1941 was ubiquitous. Even in England both the P-39 and 40 were using it. Elsewhere both planes were in service.

            Part of Bomber Command, not the DAF. The original post cited the DAF.

              462 squadron Raaf was part of 205 Group which was part of the WDAF, not bomber command. Perhaps you’re confused by the fact 462 was reformed later in the UK as part of bomber command. Perhaps you can provide a source to support your point?

                  To little to late. What is really extraordinary is how war can accelerate the introduction and manufacturing of new weapons and constant upgrades to existing ones in the "battle for superiority" over your enemy.

                  One of the commenters on the above video posted this:
                  The problem with the 152 is that by 1945 the Germans had no fuel to put in these planes, so they were just empty shells. I talked to a B-17 belly gunner, who flew on bombing missions in 1945, and stated he saw hundreds of German aircraft on airfields, but never saw a German plane in the air. When the Russians overran the Romanian oil fields in 1944, the German mechanized war stopped. The Germans built 1,500 ME-262 jet aircraft, but could only put about 30 in the air at the same time. Russia and the US had massive supplies of indigenous oil, while the Germans, Italians, and Japanese had none. Oil was a huge factor in WW2

                    • But, IMO, big radials as seen here on the Grumman Tigercat(in this case the P&W R2800 also used in the P47, Hellcat and Corsair), especially those highly tuned and with the resultant sound of "lumpy" camshaft timing at idle, sound better than the very popular V12's such as the Merlin/Griffon/Allison/DB605 et al:



                      This "lumpy" sound at idle(listen for it particularly at the very start of the video) is a compromise forced on the engine designer to allow the engine to produce extra torque at the (higher)rev range most used in combat or in high output situations like at take off, where the uneven sound smooths out(listen @20 seconds where it is smooth under full throttle).

                      Highly tuned auto/race car engines often have similar characteristics, although modern fuel injection systems/electronics are making these much less cantankerous than they once were.

                      Engine designers did not have access to these palliatives in the 1930's/40's.

                      Every aircraft engine design is a compromise, as is aircraft airframe design.

                      Some designers were better at it than others when it came to negotiating these compromises.

                      • Of course, I don't reckon anything can beat a good "blow job", as the Me262's were referred to some time after their introduction to service.


                        The Me 262 Stormbird: From the Pilots Who Flew, Fought, and Survived It

                        https://books.google.com.au/books?id...%20job&f=false

                        The German name for it was the "Schwalbe" or swallow.

                        Blow job.....swallow.....oh dear.


                        The aircraft in the following video is a "reproduction" version, not an original, and is powered by later generation engines but of the same configuration as the Jumo 004(i.e. turbo jet rather than the later and more fuel efficient/quieter turbo fan ) so the sound won't be too far from the original.

                        It is IMO, but based on the input of Captain Eric "Winkle" Brown, as from my earlier post #83 that:


                        the Me 262 “was the most formidable aircraft produced in World War II"

                        • The P-38, and other US aircraft with a turbocharging system sound more like sewing machines. They are surprisingly quiet.
