The first is that the Germans did not transfer their advanced radar to Italy for the sake of secrecy, and although Italy also relied on its own efforts to develop the radar, the detection range and accuracy were very problematic, and they did not develop a long-wave radar that could bypass the earth's curved surface and the detection accuracy was at least somewhat practical (Note 1), so it only needed the aircraft to penetrate at low altitudes to achieve surprise. However, in the case of low-altitude bombing, it is impossible for the aerial bomb to obtain too much falling kinetic energy, and the destructive power generated by the bomb explosion itself, no matter how powerful, it is difficult to pose a fatal threat to the rough-skinned battleship, so it can only use aviation torpedoes to attack.

It is said that due to some previous Chinese war examples, many people in the British Navy advocated abandoning the torpedo aircraft that has now been jokingly called "advanced target aircraft", but the conservatives in the navy finally won the victory, and now this is a blessing in disguise for the British. Moreover, because the combat plan is "ultra-low-altitude penetration + night attack", the weakness of the torpedo bomber's extremely poor survivability has been very well avoided, and even the biplane "Swordfish" carrier-based bomber, which has been criticized, has become the best choice because of its stability when flying at ultra-low altitude

But the use of torpedoes for an attack also raises two other problems, one is the depth of the water, and the other is the mine protection net. The depth of the water in Taranto was too shallow, and the torpedo was likely to fall into the sea due to the kinetic energy of the fall and sink into the sediment, or even detonate prematurely because it hit the bottom, so the British decided to reduce the throwing height. Anyway, it was supposed to take the method of ultra-low-altitude penetration.

The mine protection net is a bigger problem, because the Italian mine protection net is completely protected, if the depth of the torpedo is set high, it will be blocked by the mine protection net, and if it is set low, it will pass directly under the warship, and there is no gap to drill in between, so that the traditional trigger fuse torpedo can not hurt the Italian warship at all.

For this reason, the British Admiralty decided to use the current unreliable and unreliable magnetic fuse torpedo, which can be detonated without direct contact with the hull of the ship, and if it explodes under the warship. Even if it is not directly attached. Its power is also likely to blow up the keel and cause it to break in two and sink quickly

Of course, the reliability of the magnetic-fused torpedo is poor, but its poor reliability is that it sometimes does not explode, and it does not explode prematurely like the original oxygen torpedo of the devil. So it is only necessary to increase the number of torpedo machines put in. It's not something that can't be overcome.

For this operation. Except for two battleships that were left in Alexandria because they could not keep up, almost all the other high-speed warships of the British Mediterranean fleet were poured out, including 2 aircraft carriers, 2 heavy cruisers, 2 light cruisers, and 5 destroyers. However, at this time, Taranto's Italian navy had 6 battleships, 7 heavy cruisers, 2 light cruisers and 8 destroyers, so the British Mediterranean Fleet could only pin its hopes on the dozens of "Swordfish" bombers carried on the two aircraft carriers.

However, to the dismay of the British officers and men, three "Swordfish" crashed during an anti-submarine patrol flight during the voyage, and it was found that one of the aircraft carrier's fuel tanks was contaminated, and the fuel in this tank could no longer be used by the aircraft, but the officers and men of the fleet quickly adjusted their mood and continued to move forward

Unlike in history, the British Navy at this time was already able to form a larger bomber formation, so the bombers on the two aircraft carriers were not divided into two batches, which undoubtedly greatly enhanced the effect of the raid. And because there were already a large number of examples of air-to-sea warfare for reference, the main goal of the British was to destroy the Italian capital ships, and the airborne radar was used as an eye, so this time the British planes all brought torpedoes, instead of carrying flares, and did not bring small aerial bombs that did not have much effect as in history, so they achieved greater results

Under the sudden blow of the British, the Italian battleship Vittorio. The Veneto was hit by a full six torpedoes, the hull almost completely disintegrated, and quickly sank to the bottom of the sea. The Count of Cavour and Cailliaud. The Duilio was also hit by 3 torpedoes and 2 torpedoes, respectively, and sank one after the other at a later date. Although Italy can theoretically fish them up and repair them, even if everything goes well, it will take more than half a year, and the cost will not be small, not to mention that with Italy's ship repair capacity, at least Vittorio. The Veneto could not be repaired

In total, the British were shot down only 6 planes, and although the losses were slightly larger than in history, they were still minimal. And with such a great result at such a small cost, the Battle of Taranto became another miracle of the British Royal Navy, as in history.

However, due to the butterfly effect caused by Hu Weidong's crossing, although this victory benefited Britain in the short term, on the one hand, the Royal Navy temporarily gained sea supremacy in the Mediterranean, and on the other hand, the confidence of Britain and even the Commonwealth countries in defeating the Axis powers and achieving a final victory also recovered a lot, but from the subsequent evolution of the situation, this victory put the allies in a greater predicament. The reason for this is that after the poor performance of the Italian Army, the Italian Navy also deeply disappointed Mustache, which directly led him to make a major decision that many people did not expect - Mustache actually left the Italian government and extended an olive branch to the Klim "rebels" in North Africa

Although he suffered heavy setbacks before, the French government still increased troops to the North African colonies many times, and the military strength even exceeded 800,000 (including colonial soldiers) at the maximum, and Kerim's military talent was difficult to defeat no matter how against the sky, but he was far more open-minded than back then, but he unexpectedly divided his troops across the Sahara Desert to attack Mauritania, Niger, Mali, Chad and other places where the French colonial army was seriously underarmed, and used the advantage of the common faith to fully mobilize the local black Muslims to rise up and resist, As a result, the anti-colonial struggle in Africa became a burning order

Note 1: In fact, there is another type of long-wave radar that relies on ionospheric reflection and has a longer detection range, which is called skywave radar, and the radar wave that advances around the curvature of the earth is called groundwave radar. With the level of science and technology during World War II, it was impossible to put skywave radar into practical use anyway, so the long-wave radars that appear in this book are actually all ground-wave radars.
