Half an hour away from the No. 4452 Sea Dragon-class giant submarine, a submarine numbered No. 4450 Sea Dragon-class submarine was quietly lurking in the sea water of 200 meters, quietly sailing to the handover destination under the cover of the deep dark sea water at a depth of several hundred meters.

This behemoth in the sea water at a depth of four or five hundred meters, but from the shape it looks a bit like an enlarged version of the Typhoon-class ballistic missile nuclear submarine, of course, this guy is different from the hairy style product of the Typhoon-class double-layer shell, and there is no small pressure-resistant shell or anything like that in the inner layer; It's a pity that this guy doesn't have the habit of arranging missiles outside the pressure-resistant shell at all, of course, it is not excluded to load them later ... It looks like the Sea Dragon and the Typhoon are similar, but it is not uncommon for the Typhoon to wrap the outer layer with non-pressure-resistant materials to form a smooth shape according to the usual style of hairy bears. And between the two layers of the woolly bear is a ballast water tank or a flooded part. It is completely different from the Cold War-era creation typhoon, where a reactor and power plant are arranged in each of the two shells to drive a propulsion shaft. However, according to Zhao Heng's idea of infinite brain, this guy needs at least three to four layers of shell, one layer is not pressure-resistant, the second layer is pressure-resistant, the third layer is pressure-resistant sound insulation layer, and the fourth layer is pressure-resistant constant temperature layer; This kind of unscientific design can only be made by Zhao Heng, who has non-earth technology and black technology.

If you have to say that this guy is a simple Typhoon-scale amplified version, it would be wrong. The boat has a standard elongated teardrop-shaped hull with a sleek exterior and a streamlined nose and command station enclosure. A new type of sound-absorbing film is pasted on the outside of the hull (a layer of skin such as shark skin, which is a bionic high-tech product, and if the effect is concerned, it is greatly improved compared to the sound-absorbing tiles widely used by various naval countries in the world in later generations, and even the later naval overlord Midi has been thrown off several streets). As with the Typhoon, all the kinematic machinery in the boat is mounted on a shock-absorbing base. As a result, the boat is extremely quiet when sailing underwater. The boat has a multi-hull structure.

(The submarines of the 4400 series are almost all similar, of course, some submarines will be converted into diving aircraft carriers, and the 4450 is such a diving aircraft carrier) The previous part of the command cabin of the ship was a hangar except for the torpedo compartment at the head, which was used to park the carrier aircraft and store maintenance equipment and parts. The fuel tank is under the hangar, and the fuel tank is double-layered, which can store more than 12,000 tons of oil. The front of the command module is a straight deck, which serves as the flight deck of the carrier aircraft. The hull is made of high-strength steel, and it can dive to a maximum depth of 1,000 meters (note that at the current level of technology in the world, this is still an insurmountable black technology). The normal establishment of the whole boat is 162 crew members and 150 aviation personnel.

The design length of the 4400 series is 457.4 meters, the width is 91.2 meters, and the height (bottom to antenna) is 68 meters. Such a size is almost more than the battleships of that time, of course, compared to the catamaran super battleships of the current time and space... The two are not the same breed at all.

Let's take a look at its displacement: first of all, its surface standard displacement is much heavier than that of conventional battleships, reaching 90,600 tons, which is about the same as the largest aircraft carrier of the later Midi; However, its underwater displacement is the largest of all large submarines now, and of course the tonnage is larger than that of the Typhoon-class submarines built by the Soviet Union during the Cold War, reaching an astonishing and terrifying 108,200 tons!

The 4450 submarine is a submarine aircraft carrier, and its flight deck width is twice that of the I-400 series of diving carriers equipped by small Japan, reaching 49.2 meters, and its deck length is not much different from that of most aircraft carriers of World War II, reaching an astonishing 240 meters. The deck has a twin runway, reserved for two electromagnetic catapults as a backup, for the future two jet fighters to quickly take off one after the other, currently taking off this foldable wing version of the HNA loose incense MKB-SPEC coaxial reverse propeller canard fighter (from a production aircraft equipped by the Eternal Child in the anime "Sky Killer").

The power system of this type of aircraft-carrying nuclear submarine is very peculiar in this era, unlike the diesel engine and battery used by U-boat and Yi series submarines. This giant guy actually has 4 sets of relatively independent nuclear power units (you read that right, the cold fusion nuclear power version), 4 new gas turbines, 4 propulsion shafts, 4 pump jet propulsion, each power shaft has an independent power system, and 4 sets of parallel connections, which can save emergency electric propulsion systems. Noise generated by the propeller is eliminated, further enhancing stealth performance. The boat adopted an X-shaped tail rudder. The maximum speed at the surface is 36 knots, and the maximum speed underwater is 66 knots (in terms of speed, it is still slow compared to the blue Iron Maiden battleship).

The weapons systems of aircraft-carrying nuclear submarines were not designed from the very beginning for the main purpose of direct engagement, but the necessary weapons systems for self-defense were needed. Due to their large size, submarines of this type are generally equipped with 16 torpedo tubes in the bow, of which 8 are 650 mm and 8 are 533 mm. The torpedo tube can fire four types of ammunition: the Yu-18 torpedo, with a speed of 90 knots and a range of 50 nautical miles; Yu-19 torpedoes with a speed of 120 knots and a range of 35 nautical miles; Torpedoes can carry 96 pieces. The boat can also perform the relatively simple task of laying mines to block the entrance and exit of a certain seaport area.

The aircraft-carrying nuclear submarine will be equipped with electronic systems, which are the most advanced electronic equipment in the world today with the obvious black technology provided by Zhao Heng. Its new sonar system will include an advanced bow timing/passive ball array sonar system (and I have to say that the two modes are actually freely convertible, even if no country in later generations has done this, but I can't tell...... The side of the boat is equipped with a side-array passive sonar system, and there are two accommodating cabins above the X-shaped tail rudder, which contains a towed line array sonar system towed line array sonar (tactical towed line array sonar is equipped with large and medium-sized anti-submarine surface ships and attack submarines, and the towed cable and line array are up to 1000 meters ~ 2000 meters in total Passive detection distance of 50 nautical miles ~ 100 nautical miles, and the maximum towing speed can reach 30 knots.

The tactical towed line array sonar of surface ships works in conjunction with hull sonar or towed body sonar to passively receive the echo generated by the active sonar emission sonar signal on the target, and its action distance is much greater than the active detection distance of the hull sonar or towed body sonar when working alone, so as to improve the anti-submarine search capability of surface ships. Surveillance towed line array sonar, mainly equipped with marine surveillance vessels. Its towing speed is extremely low. The total length of the towed cable and line array is more than 5,000 meters, and the passive detection distance can reach more than 300 nautical miles when working in the low sound frequency and infrasound frequency band. ）。 and active high-frequency sonar: a series of sonar systems that will help submarines search for all underwater and surface targets. I have to say that it is a very good and powerful system, but Zhao Heng has been getting bigger and bigger recently, completely beyond the current science in this world......

The boat will be equipped with a global navigation system equipped with the "Sky Eye 2" multi-function satellite to navigate it. And when the submarine surfaced, this guy also turned on a collapsible multi-functional passive phased array radar hidden (black technology does not explain) to help the submarine search for air and surface targets within 500 kilometers, so as to ensure the air safety of the submarine and provide early guidance for fighters. The boat will also be equipped with a high-power all-band electronic jamming system, an advanced command and control system, and a friend or foe identification system.

First of all, the carrier-based aircraft of this submarine will be the core combat force of this type of submarine, so its combat power cannot be lower than that of the advanced fighters of various countries in the current era, and its combat effectiveness must be strong. This type of submarine was first put into service around 1938, and its main fighter is the self-developed fighter Sanxiang MKB-SPEC coaxial reversal propeller canard wing fighter, and the performance of the aircraft is already the limit of the piston engine in this era, and it is also a fighter advanced enough, so it can be improved to the carrier-based fighter of the 4400 type aircraft-carrying nuclear submarine, and its development cost is very low (Zhao Heng is very lazy and directly copied the design of the book to develop the seismic canard wing local fighter at the end of World War II).

The 4400 carrier submarine is equipped with the Sanxiang MKB-SPEC coaxial counter-propeller canard fighter is different from the original, with a wingspan of 9.44 meters, a total fuselage length of 9.54 meters, a total fuselage height of 4.2 meters, and a main wing area of 20 square meters.

The replica of its own engine ARGOS-666E1 liquid-cooled 12-cylinder 48-valve diesel version has a maximum power of 3,500 horsepower, while the on-board radar is a model of TS-08_Z, and the fuel used by itself is the use of fuel new C41 aviation diesel, the empty weight of the fighter is 3.15 tons, and the maximum weight of the fighter is 5.72 tons.

The maximum flight speed of the aircraft at about 900 km/h has exceeded most propeller aircraft at that time, and its cruising speed is rare to reach some civil large jet airliners in later generations of about 680 km/h, its practical ceiling is to break through 15,000 kilometers, this figure reaches 16,000 kilometers such an amazing altitude, and its range range of 1280 kilometers is not inferior to the early jet fighters, and the aircraft landing speed is about 150 km/h.

The onboard armament is a total of 6 QJG-02G 14.5mm anti-aircraft machine guns on the left and right sides of the nose, which is more powerful than the Browning 12.7mm heavy machine gun! And equipped with 500 rounds of 14.5 mm bullets per box of ammunition chained ammunition box; and the weapon frantically reached the level of the Western 20 mm anti-aircraft guns in the later generations, the machine gun muzzle velocity in 995 m/s (through the detonation of the bomb), 1250 m/s (shelling bomb) to completely explode the fighter guns of this era, to get this kind of fighter is completely Zhao Heng's lazy idea, the result of a test is very good, no matter what fighter you in World War II can not escape the fatal damage of this weapon. Of course, in order to avoid damage to the fighter by recoil, a mechanical-hydraulic recoil counteraction device was specially installed at the tail of the machine gun.

Therefore, the Type 4400 aircraft-carrying nuclear submarine will be able to carry 48 fighters called J1-H and 8 JE-4H electronic warfare aircraft. If necessary, the vessel may also carry helicopter gunships or serve as a temporary transit point for helicopters. Of course, for Zhao Heng, it is not yet time for armed helicopters and helicopters to appear, so it is still the J1-H fighter as a cheating-level weapon.

The take-off and landing process on the Type 4400 aircraft-carrying nuclear submarine is like this, first of all, the first thing after the all-time giant submarine surfaced was to lift 1-3 fighters under the command cabin by two elevators with a load of 30 tons installed in the carrier aircraft channel, and the door in front of the upper part of the channel was automatically opened, and the fighters were dragged to the take-off position by the tractor, and the ammunition could be transported out by the 30-ton elevator with the fighter, or it could be transported out by the ammunition elevator after reaching the take-off position, and then the fighter aircraft taxied and took off; When the fighter returns, it lands on the flight deck in the same way as a normal fighter, and then pulls it back into the carrier tunnel by the tractor, and then carries it back to the hangar by the elevator.

In wartime, the core task of the ship is to cooperate with surface ships and land-based fighters to send carrier-based aircraft to launch a sudden and fatal attack on the enemy's aircraft carrier task force.
