After determining the aircraft carrier, battleship and cruiser, the next step is to choose destroyers, frigates and submarines, these three types of battleships Chen Feng has already thought about it, and he chose the domestic one, the domestic performance is good and inherits the fine tradition of Chinese manufacturing - the price is cheap!

Domestic missile destroyers are made up of 051, 052, 055 and other models, and frigates are 053H1, 054, 056 and other models, after comparison, Chen Feng selected the two most cost-effective ones, one is the 051 type destroyer, the other is the 053H2 type frigate.

The Type 051 destroyer is a first-class destroyer built by China in the seventies and eighties of the twentieth century, and is a first-class destroyer built by China itself. There are 6 types of destroyers of this type together with improved models, including Type 051, Type 051D, Type 051Z, Type 051DT, Type 051S (planning aborted), Type 051G1/G2, and Chen Feng selected the most original model, Type 051.

The Type 051 destroyer has a hull size of 132 meters in length, 12.8 meters in width, and a draft of 4.6 meters. The displacement standard is 3,250 tons, the full load is 3,670 tons, the power is 2 boilers with twin-shaft propulsion and 2 steam turbines, the maximum output is 72,000 horsepower, the maximum speed is 36 knots, the endurance is 2,970 nautical miles, and the staffing is 280 people, including 45 officers.

The Type 051 destroyer is armed with two twin 13O mm guns with an elevation angle of 85 degrees and a firing rate of 17 rounds per minute with a range of 29 km, and four twin 37 mm artificially operated anti-aircraft guns with an elevation angle of 85 degrees. Firing rate 180 rounds / min, range 8.5 km, two twin 25 mm guns, 85 degrees elevation rate 270 rounds / min, range 3 km, two FQF250O 12-tube fixed launchers (120 rocket depth bombs; firing range 1200 meters; warhead 34 kg).

4 BMB-2 deep bomb launchers, 2 deep bomb delivery racks, and two triple "Sea Hawk-2" (HY-2) missile launchers; Active radar or infrared guidance, 0.9 km at Mach 95.

The electronic equipment includes anti-air groping (354 eye-shield anti-air search radar), sea search (fine mesh sea-to-sea/low-altitude search radar), and long-range alert (515 mesh long-range anti-air warning radar).

In general, foreign military circles do not have a high opinion of this class of ships. It is considered that its level is only equivalent to that of the fifties and sixties of the twentieth century. This is mainly due to the limited level of industry in China and the lack of sufficient experience of the design team. The main problem is that it lacks effective air defense and anti-submarine firepower, and at the same time, the structural design is backward, and the entire hull has few waterproof compartments. There is also a lack of adequate protection between the cabins. Poor design resistance to sinking and damage.

In addition, there is no perfect air-conditioning equipment and nuclear, biological and chemical three-proof system. Communications and electronics lagged behind, and earlier models did not have an integrated combat command center. The tonnage is too small, and the length to width ratio of the ship is large. It is unfavorable to stiffness and strength, and the seaworthiness is poor. The human-machine interface is poor, the habitability is not good, the temperature of the machine furnace room is high, there is no restaurant, and the living conditions are very difficult.

Despite its many drawbacks, the price is very cheap and only costs 8000 credits. And its performance is not as unbearable as the outside world says, there is no problem at all to deal with the cruisers of the little Japan, whether it is in terms of firepower or speed, the cruiser of the little devil is completely destroyed, as for the destroyer of the little devil, it is not an opponent of the same level at all.

The Type 053H2 frigate is a series of sea-facing missile frigates built by China after 053H and 053H1, which is developed from the Type 053H1 ship, and the hull adopts a fully enclosed, fully air-conditioned, and long bridge structure. The normal displacement is 1700 tons, the full load displacement is 2100 tons, the main engine adopts 2 sets of 18E390A diesel engines, the total power is more than 20000 horsepower, and the maximum speed can reach 30 knots.

The Type 053H2 frigate weapon system includes eight YJ-81 ship-to-ship missiles, and auxiliary weapons include two twin Type 79 double-barreled 100-mm automatic cannons in the bow, four twin 37-mm anti-aircraft cannons and two five-barreled anti-submarine rocket launchers, which are not much different from the Type 053H1.

In addition, the Type 053H2 frigate is also equipped with a large number of electronic equipment, including one Type 354 two-coordinate sea search radar, one Type 352C sea search/anti-ship missile fire control radar, one Type 752A or RM-1290 navigation radar, and one Type 343 100 mm naval gun fire control radar.

Although the performance is very good, the price is not very expensive, not counting the ammunition production line, a Type 053H2 frigate only costs 5000 points.

After the main warship is selected, it is necessary to choose the submarine, and in comparison, the selection of the submarine should be more cautious and cautious, and the submarine is equipped with the ability to use the cover of the water layer to carry out covert activities and carry out surprise attacks on the enemy; In addition, it has a large self-sufficiency, endurance and combat radius, which can be far away from the base, and can fight independently in a longer period of time and a larger ocean area or even deep into the enemy's sea area, and has a strong assault power; It can launch missiles, torpedoes and lay mines underwater to attack sea and land targets.

In naval warfare, it is not only the nemesis of transport ships, but also the adversary of large and medium-sized combat ships, especially aircraft carriers. Among the 42 aircraft carriers sunk before the Second World War, 17 aircraft carriers were sunk by submarines, accounting for 40.5%, of which 15 were sunk by submarines alone and 2 were sunk in cooperation with aviation; Of the 38 aircraft carriers damaged, 9 were damaged by submarines, accounting for 23.7 percent.

Among the existing combat forces at sea, surface warships and shore-based air forces have shortcomings such as limited combat radius and weak survivability, and it is possible to launch an attack on aircraft carriers only when they enter the effective combat radius. However, aircraft carrier formations, on the other hand, rely on their advantages of wide combat range and good maneuverability, and in the vast majority of combat operations, they are deployed at a distance far from the combat target.

In this case, it is possible to surprise it only with submarine forces. In the more than half a century since the end of World War II, although anti-submarine forces and weapons have developed greatly, seawater is still an effective barrier for submarine concealment.

At present, all countries in the world do not attach much importance to submarines, especially Britain and the United States, because the United Kingdom, the United States and other naval powers at that time were still skeptical of submarines, and always believed that submarines were just weapons used by weak and small countries for sneak attacks, and this hindered the development of submarines.

But they will soon taste the bitterness, and the Germans will use a new tactic to beat the invincible British Navy to the bitter one, and this new tactic is the wolf pack tactic.

"Tigers are afraid of wolves", bloodthirsty wolves make all the behemoths in nature shudder, and under their repeated siege, even the king of beasts will not be spared. During the Second World War, Nazi Germany's admiral Dönitz pioneered the "wolf pack tactic" of naval warfare and took the helm of the wolf.

After the German occupation of France, the ports on the west coast of France and the Bay of Biscay were transformed into German submarine bases. The German submarine production line at full capacity had also produced a number of new submarines for use by the troops, and the wolf pack tactic had entered its most glorious period at this time.

The record for the highest attack by a German submarine was the sinking of 38 Allied merchant ships in two days, and in 1942 alone, German submarines sank a total of 471 Allied ships with a total tonnage of nearly 2.2 million tons. Of these, Britain suffered the most. In 1942, the German "wolf pack" reached the peak of sinking Allied merchant ships, sinking a total of 1,160 merchant ships with a total tonnage of 6.3 million tons, while its own loss rate was less than 7%.

The great success of the wolf pack tactics also made the Nazi German Navy rampant in the early days of World War II. The "wolf pack tactic" and Guderian's "blitzkrieg" are called the two "magic weapons" of the Nazi German army on land and sea.

How could Chen Feng miss such an important naval weapon, but Chen Feng took a look at the list of submarines from various countries in the world, the most advanced nuclear-powered submarines are still the most expensive, and any one requires tens of thousands of points, and submarines have great requirements for quantity, no matter how advanced the performance of three or two submarines is, the threat to the enemy is not very great.

It is completely conceivable that in tens of thousands, or even tens of millions of square kilometers of sea, a submarine is nothing, even if it is blocked in the golden waterway, it may not be able to meet a ship in a day. Even the most advanced nuclear-powered submarines pose a limited threat to the Japanese, who have a staggering number of ships.

But if there are dozens, hundreds, or even hundreds of search submarines, the effect will be completely different. In Germany, for example, during the war, submarines of various countries sank a total of 192 combat ships. The use of submarines to attack merchant ships on the sea lines of communication has achieved even more remarkable results, with submarines of various countries sinking more than 5,000 merchant ships, amounting to 14 million tons. Among them, more than 1,300,000 tons of merchant ships were sunk by German submarines.

Therefore, this submarine is a must, and there are a large number of equipment troops, in the case of limited points, which kind of submarine to choose is the most important, Chen Feng at this time believes that the performance of some submarines can be appropriately sacrificed for the sake of quantity, which is also completely understandable.

In Chen Feng's mind, the number of 40 is the most appropriate, which means that the navy should be equipped with at least 40 submarines. Chen Feng calculated that 6 aircraft carriers need 330,000 points to count the ammunition production line, and 1 battleship needs 38,000 points to count ammunition.

Soviet-made cruisers cost 15,000 points each, 5 ships are 75,000 points, and 95,000 points if you count the ammunition production line.

The U.S. Leahy-class missile cruisers cost 17,000 points each, 5 ships are 85,000, and the ammunition production line requires 105,000 points.

Plus 15 destroyers, 7,000 points each, plus the ammunition production line, you need at least 130,000 points. 20 frigates, 5,000 points each, plus the ammunition production line, also need at least 120,000 points, so calculated, the 920,000 points in Chen Feng's points account are only a little more than 100,000, so you must choose a submarine that can meet the needs of operations and is cheap.
