In general, when it comes to battleships and their ancestors battleships with dreadnoughts, first of all they begin to compare with each other. On the one hand, it is logical, the battleships were created primarily to fight their own kind (everything that is smaller than them, they allowed to the bottom by definition), hence the corresponding requirements for speed, booking and armament. Opponent had to catch up, or go away from him, if it smells like roast, hence the very impressive speed. It was necessary to withstand the blow of the enemy, hence hundreds of millimeters of armor. According to the enemy, in a short time it was necessary to release a large number of shells, hence several towers, from which the trunk sticks out on the 3. And what to do when the enemy is safely drowned or holed up in the harbor? It is widely believed that after Tsushima and ending with nothing and nothing (OK, the Germans formally won on points) of the Jutland battle, there was not much work for the battleships, or they, like Yamato, went ahead with a song to death under a barrage of bombs and torpedoes. As if not so: the same sunk battleships in Pearl Harbor were raised and repaired by the year of 1944. These old ruins could no longer chase the Japanese squadrons, the speed was not the same, but they greatly contributed to the stripping of the Japanese of various islands. The island and the Japanese fortifications will not run away anywhere, and the shells by the ship with a displacement of several tens of thousands of tons are in abundance.
After World War II, the use of battleships as floating batteries continued, for example, an 406-mm projectile was left simply by chic craters in place of the Vietnamese jungle. The last time the main caliber guns opened fire during the "Storm in the desert." In fact, the battleship of the Second World War is capable of striking 40 + km at a distance with shells weighing more than a ton. Of course, the accuracy is limited by accidents affecting the flight of the projectile, but the shells themselves are worth pennies compared to the guided bombs and the cost of the flight for their delivery. Missed meters on 30, repeat with the amendment.
The question arises: is it possible, instead of an ultra-high-speed steel monster, producing maximum shells for the minimum of time on the same moving target, to build a well-armored artillery ship not for fighting its own kind, but for shelling the coast? The speed of such a ship is not needed, huge savings are achieved in the power plant and fuel, while shooting for the most part will take place on requests from ground forces, i.e. in small batches, which means dragging 8-9 guns in 3-4 towers not required, enough 2 turrets for 2 guns. In fact, the battleship is obtained at a new technological level. Acting such a ship, like an aircraft carrier, should be part of a compound that will take on air defense and anti-submarine defense, which means that additional armament can be minimized: near anti-aircraft defense and anti-aircraft defense, which can be used by some Somali pirate or terrorist in a boat loaded with explosives to drown. The displacement of the battleships of the 19-20 turn of the centuries with four 305-mm guns was about 15000 tons, something similar should happen and we, if not less, can also save on armor, and leave the 150 armor belts. Yes, and 305-mm gun - it is very harsh, to counteract such a little that count.
Compared to the era of the Second World War, such a ship will have a number of advantages:
1. The plane then cost a penny, cheaper tank, now for the price of one aircraft you can buy a tank company. Plus departure price. Each cruise missile has a sophisticated engine, a sophisticated navigation system, all one-time. In fact, it is a disposable aircraft. The shell is worth a penny. Just like pennies (and even a negative amount due to the need for disposal) are high-explosive bombs, abundantly poured by our bombers on the heads of Ishilovites and other abnasra. Artillery generally solves any tasks much cheaper than aviation, the only question is range.
2. The torpedo bombers disappeared as a class. Divers, too. And the resistance to subsonic anti-ship missiles at an armored ship should be very high. As with any shelling from the ground. Stationary coastal batteries of the same battleships in the presence of cruise missiles simply lose their meaning. To sink such an armadillo will not be easy.
3. Modern air defense systems can be provided within a radius of tens of kilometers, and even hundreds. 70 years ago, only fighters could make long-range interception of aerial targets, now it will be perfectly available with missiles. On the other hand, if not the same, then similar enemy air defense systems readily repeat the one described at the beginning of the article. history, but already with our planes. Before the aircraft carrier can really help someone, he will have to somehow solve the task of suppressing enemy air defenses.
4. The projectile can be equipped with homing tools. The 152-mm guided projectile Krasnopol and its foreign counterparts Copperhead and Excalibur have been around for a long time. You can use shells with an extra long range. Zamvolt was about to spit on a 120-mm cannon for 155 km. For operations to capture the bridgehead, where you can then deploy and capture the airfield, the defeat range is quite enough. You can even clear the sky for aviation, destroying, among other things, the detected SAM batteries. The highest efficiency, when receiving the coordinates of the target, it is enough to charge the gun and enter the coordinates into it, the computer will calculate all the necessary pointing angles instantly. Well, if the range is not enough, then, if necessary, you can connect the "Gauges", which can also be folded into a small specialized carrier (arsenal ship) and strategic aviation. In fact, the Zamvolt is such a “battleship” for shelling coastal areas, only without armor, a pair of ultra-long-range guns and it is unclear why the Tomahawks pack, that is, everything that was possible was crammed onto the ship. A sort of floating T-35. Although the idea of an arsenal ship that could carry hundreds of cruise missiles, launching them on command, has already been like 30 years old. But, apparently, the construction of extremely simple systems did not meet the task of developing the funds allocated to the American the fleet.
You do not need to perform acrobatic tricks on speed ejection, when an aerofinisher cable breaks or another trouble occurs on an aircraft carrier, and build monsters in 100 000 tons, living in Midway’s realities with Guadalcanal. Everything you need to successfully install your flag on a foreign shore was invented even in the 19 century, and much earlier, in those very times when they learned how to make powerful floating batteries from ships.
Maybe someone will have a question: if everything is so simple (to develop, for example, an 254-mm gun and a ship with a displacement of 10-15 thousand tons, to install it, compared to the design and construction of even a mini-aircraft carrier - the simplest task) why not build? Well, apparently, for the same reason that aircraft carriers are not building either. The task of disembarking a couple of thousand kilometers from home beyond the reach of ground aviation is simply not worth it, or rather, the probability of such an operation is estimated as negligible.
