readx; In the 1923 improvement plan, they used the Mark 2 2-pounder naval gun to improve, and the body barrel was increased to 56 times and 112 times, and the former had an initial ammunition velocity of 732 meters per second, and the latter was 701 meters per second, with a rate of fire of 115 rounds per minute, respectively, to hit enemy aircraft in different airspace. The pen "Fun" Pavilion www.biquge.info ammunition used a chain to feed a group of 14 rounds, and began to use a braided bullet chain, and later simply used a steel bullet chain.

In the end, the British Navy had no choice but to accept this problematic weapon, and mixed the two types of guns with 4 pieces each as auxiliary weapons for the air defense of the battlefleet. The single-barreled 2-pounder gun is also used flexibly on small vessels such as frigates. The last Prince of Wales equipped with these anti-aircraft guns was finally sunk by the Japanese in Southeast Asia, and the Porfors only played the advantage of high speed, and in the absence of tracer shells and large effective range, such anti-aircraft capabilities were limited, and finally this outdated and unsuitable Porfors began to give way to the Swedish Bofors 40 anti-aircraft guns of the same caliber (or the better Bofors). So whether it was at that time or in later generations, this thing is a pit existing.

It is very peculiar that the maximum speed was set at 30 knots in that era, and you don't see that other naval powers have been greatly increased by the maximum speed of battleships by 35 knots, why don't John Bull make it into an engine with a maximum speed of 40 knots or something like that, is it that you can't get this kind of engine or the technology is not up to par or what?

In a certain mindset, the protection requirements of this battleship are different from those of other countries, and God knows why John Bull's cerebral groove circuit is different from others, and we really want to know why.

First of all, for horizontal protection, John Bull thought that it was best to withstand 16-inch shells fired from 14,000 yards (12,802 meters), but in the middle of World War II, the 460-mm main gun appeared in the book, which became a nightmare designed to protect against 16-inch shells.

secondly, vertical protection was required, capable of resisting 1,000 pounds (454 kg) of armor-piercing shells dropped from a height of 15,000 feet (4,573 m); and can withstand 30,000 yards (27,432 m) of 16-inch shells fired from a distance. It was well defended in the middle of World War II, but it was not so beautiful in the later period.

The protection outside the furnace compartment can be lower than the standard of the ammunition compartment, but if you encounter the 460 mm main gun, you can only wait to be exploded, because at that time the outside of the furnace cabin has been broken, and the engine inside will be scrapped directly for this reason, and the battleship can't run if it wants to, and it can only become a dish for a strong opponent.

John Bull, who has a bag in the braincase, also asked the battleship to withstand the 1,000-pound (454kg) TNT equivalent explosion under the water, but the problem is that if it encounters a TNT equivalent explosion of more than or even one ton in the future, the battleship can only stage a dolphin jump posture (the explosion flies up and falls on the water to split in half and sink to the bottom of the sea, when the fish in the sea are a new paradise).

In the development requirements set out above, the defense standard was set to be able to withstand 16-inch guns (the weight of shells was not specified). But there is no provision to limit the standard displacement of new ships. This gives designers a lot of leeway to achieve design standards. That's all there is to it, how can you resist artillery beyond that size, it seems that there is only one more first-class battleship? It's just a waste of time and energy, and in the end, nothing will come of it.

Over the next two months, preliminary design work began. So in April, 4 schemes such as 16d-16g with a standard displacement of more than 40,000 tons were introduced (what the hell is this?). ）。 According to the first scheme 16D standard, the displacement reaches 42500 tons, which fully meets the requirements put forward by the Navy Staff at the current stage.

The second scheme 16E has 4 turrets with 12 main guns. The standard displacement reached 48500 tons. However, the main engine output is the same as in several other schemes, with only 120,000 shaft horsepower. So the speed... There are only a pitiful 26 verses. In order to achieve a maximum speed of 30 knots, the standard displacement must exceed 50,000 tons.

Although at that time the Admiralty preferred this scheme. But its biggest drawback is that its size exceeds the Rossyth and Portsmouth shipyard limits. And equipping 4 turrets is difficult to design. A width of 110 feet (exceeding the Panama Canal limit) and a draft of 35.17 feet (exceeding the Suez Canal limit) also do not allow for rapid global deployment.

The third plan is just right, and it just so happens that the 39,500-ton 16F was formulated in response to the government's intention to limit the displacement of the additional clause to 40,000 tons, which is very much in line with the provisions of the treaty. As a result, it ended up with only 12 secondary guns.

The fourth scheme, 16g, is a retro scheme of the dreadnought period equipped with torpedo tubes. The standard displacement is 43000 tons, which is a bit more than the tonnage.

The main thickness and arrangement of the armor of these 4 schemes are the same as those of the K-G-V. The design requirements for withstanding 16-inch shells were achieved primarily by adding additional anti-shrapnel armor to important areas. The above designs all reflected the trend of increasing protection, firepower and speed of new battleships at that time by controlling the displacement by technical means. In addition, the Admiralty proposed in the design requirements the equipping of the radar.

The meeting of the Admiralty Ministers was held on May 26, 1938, and the final decision was made to adopt the 16F plan. But it was necessary to increase its standard displacement to meet the requirements for the number of 16 secondary guns, as well as to increase the thickness of the main armor belt and the power of the main engine. Based on these directives, the new scheme 16f was soon introduced, and the contract design period began in July and ended in September. In the face of the increasing air threat, the military demanded that the original number of "bang bang" guns be increased from 4 (8 in pack) to 8. However, it was difficult to find a suitable position for so many anti-aircraft guns that were not affected by the opening of the main and secondary guns. The best position for these anti-aircraft guns was in the middle of the hull between the front and rear chimneys. But the British laid out seaplane-related equipment here. In the end, a compromise was adopted: the "Bang Bang" guns were 6 and 48 guns, and the number of aircraft was reduced from 4 to 2.

Then, on September 15, 1938, the Admiralty approved the final design and immediately invited tenders from the shipyards, which ended on February 21 of the following year. Such swift action is a reflection of the Admiralty's desire for the new ship to be built as soon as possible.

The Lion class is an improved version of the George V class. Not only does it retain the basic features of the K-G-V in terms of appearance, but its interior layout can also be said to be a copy of the K-G-V. It was a typical fast battleship, and it also pinned on the expectations of the British to maintain their leading position in the field of battleships.

Construction of the first two Lion ships, the Lion and the T-EM-ER-A-I-RE, began on 4 July and 1 June 1939 at Vickers Armstrong's Newcastle and Kemore Laird shipyards in Birkenhead. The British hoped that the two ships would be completed in time for 1942. The third Conqueror is scheduled to begin construction at Clydebank in August, and the fourth Thunderer, although scheduled to be built at Glasgow's Fairfield Shipyard, has never actually been ordered. After the outbreak of World War II, the Lion and Savage were still being built as planned. But in October, an order was issued to suspend the construction of two warships for a year. In this way, part of the completed steel structure of the hull rests on the slipway. In the end, it was tragic that it did not make it to the Second World War......
